If tan theta=5/6 and tan gamma=1/11 the show that (theta + gamma)=180/4​

Answers

Answer 1

(theta + gamma) = 45 degrees, which is equal to 180/4.

Property of right-angled triangle.

tangent of an angle is defined as the ratio of the opposite side to the adjacent side of a right-angled triangle.

Let's consider a right-angled triangle ABC, where angle B is 90 degrees, and angle A(theta ) and angle C(gamma) are the angles whose tangent values are given.

Using the given information, we can say that:

tan(A) = 5/6

tan(C) = 1/11

We can now use the following trigonometric identity:

tan(A + C) = (tan(A) + tan(C)) / (1 - tan(A) * tan(C))

Substituting the given values, we get:

tan(A + C) = (5/6 + 1/11) / (1 - 5/6 * 1/11)

tan(A + C) = (55/66 + 6/66) / (66/66 - 5/66)

tan(A + C) = 61/61 = 1

Now, we know that:

tan(180/4) = tan(45) = 1

Therefore, we can conclude that:

A + C = 180/4 = 45 degrees

Hence, we have shown that (theta + gamma) = 45 degrees, which is equal to 180/4.

The x ≤ 32Putting x = 24 in the expression we get RC = 96Therefore, the value of RC is 96.

In order to find RC, we will make use of the given information in the following manner: Given that ABDC is a parallelogram. Hence, AB = DC. We have also been given that PQ = 735 and QR = 112.Now, extend PQ to meet DC at S.Let PS = x; then DS = DC - x = AB - x. (Since AB = DC)We have that PS/SP = QR/RB (Since PQR is similar to DBR)Therefore, we getx/SP = 112/(AB - x)We can cross multiply and simplify to getSP = (112* x)/(AB - x)......(1)Further, we have that AQ/QB = SP/BR (Since PQR is similar to AQB)Therefore, we getx/(AB - x) = SP/BROn substituting the value of SP from equation (1) above, we getx/(AB - x) = (112* x)/(BR*(AB - x))Therefore, we getBR = (x*(AB - x)*QR)/[PQ*(AB - 2*x)]BR = (x*(32 - x)*112)/(735*(32 - 2*x))BR = (56*x*(16 - x))/(245*(16 - x))BR = (56*x/245)Since the sum of all sides of a parallelogram is equal to the sum of its opposite sides, we have thatRC + QR = AB + AQ - QBRearranging the terms we getRC = AB + AQ - QB - QR......(2)Now, AQ = PQ - APSubstituting the values of PQ and AP we get AQ = 735 - (DC - x) = 735 - 32 + x = x + 703Also, QB = AB - AQ = (32 - x) - (x + 703) = -x - 671Substituting the values of AQ and QB in equation (2) above we getRC = 32 + (x + 703) + (x + 671) - 112RC = 48 + 2xRC = 2(x + 24)We know that AB = 32, hence, x ≤ 32Putting x = 24 in the expression we get RC = 96Therefore, the value of RC is 96.

Which of the following statements most accurately describes the relationship between cultured yeast preparation conditions and fermented alcohol yield, based on passage data?Neither glucose concentration nor percentage yeast inoculate was positively correlated with fermented alcohol yield.A is correct. Table 1 shows that the maximum fermented alcohol yield was obtained in Broth A, with 10% glucose (not 12%, as in Broth C) and 8% yeast inoculate (not 10%, as in Broth B). Therefore, increasing neither glucose concentration nor percentage yeast inoculate led to more production of alcohol, so neither of those parameters showed a positive correlation with alcohol yield.

Answers

Based on the passage data, the most accurate statement describing the relationship between cultured yeast preparation conditions and fermented alcohol yield is: "Neither glucose concentration nor percentage yeast inoculate was positively correlated with fermented alcohol yield."

What this means is that increasing the concentration of glucose or percentage of yeast inoculate did not lead to more production of alcohol. The data in Table 1 shows that the maximum fermented alcohol yield was obtained in Broth A, which had 10% glucose and 8% yeast inoculation. Broth C, which had a higher concentration of glucose at 12%, did not result in a higher yield of alcohol. Similarly, Broth B, which had a higher percentage of yeast inoculate at 10%, did not lead to a higher yield of alcohol.

Therefore, it can be concluded that neither glucose concentration nor percentage of yeast inoculates was positively correlated with fermented alcohol yield.

Suppose you roll a special 37-sided die. What is the probability that one of the following numbers is rolled? 35 | 25 | 33 | 9 | 19 Probability = (Round to 4 decimal places) License Points possible: 1 This is attempt 1 of 2.

Answers

Answer:

5/37

Step-by-step explanation:

There are 37 possible outcomes when rolling a 37-sided die, so the probability of rolling any one specific number is 1/37.

To find the probability of rolling any of the given numbers (35, 25, 33, 9, or 19), we need to add the probabilities of rolling each individual number.

Probability of rolling 35: 1/37

Probability of rolling 25: 1/37

Probability of rolling 33: 1/37

Probability of rolling 9: 1/37

Probability of rolling 19: 1/37

The probability of rolling any one of these numbers is the sum of these probabilities:

1/37 + 1/37 + 1/37 + 1/37 + 1/37 = 5/37

So the probability of rolling any of the given numbers is 5/37, which is approximately 0.1351 when rounded to four decimal places.

The ratio of gold to silver to bronze medals won by Belarus in its simplest form is 4:0:1, which means that Belarus won four times as many gold medals as bronze medals, and no silver medals.

What is simplest form ?

In mathematics, the simplest form refers to the most reduced or compact form of an expression.

The simplest form can be achieved by simplifying, reducing, or condensing a mathematical expression or ratio to its smallest possible form using various techniques such as factorization, cancellation, and distribution.

To find the ratio of gold to silver to bronze medals won by Belarus, we need to look at the row corresponding to Belarus in the table:

Country Gold Silver Bronze

Belarus    8             0              2

The ratio of gold to silver to bronze medals won by Belarus is: 8:0:2

However, this ratio is not in its simplest form, because we can simplify it by dividing all of the numbers by the greatest common factor of the three numbers. In this case, the greatest common factor of 8, 0, and 2 is 2, so we can simplify the ratio by dividing each number by 2:

8 ÷ 2 : 0 ÷ 2 : 2 ÷ 2

Answers

To estimate the difference between the giving rates of school A and school B, we must first identify the missing value. It is not given in the statement.

1. However, it can be assumed that the giving rate of school B is 0%, as the difference between the two figures should be expressed as a percentage.

If school A has a graduation rate of 90%, we can estimate its giving rate as follows: Given that school A's graduation rate is 10 points higher than school B's graduation rate, the Giving rate of school A = (90 + 10)% = 100%Thus, school A's giving rate is expected to be 100%.

2. If we learn that schools A and B have identical student-to-faculty ratios, the answer to the previous question would not change. The student-to-faculty ratio has no bearing on the graduation and giving rates of the school.

The student-to-faculty ratio is a measure of class size and may be used to determine how well the school is prepared to manage the educational needs of its students.

3. The question does not provide a list of 123 schools to choose from. It is not possible to determine the school with the highest or lowest giving rate without this information.

4. To calculate whether the school's giving rate is greater or lesser than 8%, we must first estimate the value of the giving rate. The problem statement does not provide a clue to the school's giving rate.

Nonetheless, we can estimate that the giving rate of a school with a 67% graduation rate and a freshman retention rate of 77% would be relatively lower than 8%. Schools with a higher graduation rate are more likely to have a higher giving rate because their alumni are more inclined to contribute to the institution.

Therefore, it is not possible to calculate the school's giving rate without more information.

James bought a total of 7 yards of ribbon for his craft project.

To begin with, let's first convert the length of the ribbon from feet to yards. There are 3 feet in a yard. So, to convert 2.1 feet to yards, we need to divide it by 3.

2.1 feet ÷ 3 = 0.7 yards

So, each piece of ribbon is 0.7 yards long.

Now, let's calculate the total length of ribbon James bought by multiplying the length of each piece of ribbon by the total number of ribbons he bought.

What is multiplication?

Multiplication is a mathematical operation that involves combining two or more quantities to find their product. The quantities being multiplied are called factors, and the result of the multiplication is called the product. Multiplication is denoted by the "×" or "*" symbol, and is read as "times" or "multiplied by". Multiplication has many applications in mathematics and everyday life. It is used for calculating areas and volumes, scaling objects, calculating distances and speeds, and much more. It is also a fundamental operation in algebra, calculus, and other branches of mathematics.

Here,

To find out what number is equal to 0.02 times 100, we can use the formula:

0.02 * 100 = x

where "x" is the number we want to find. To solve for "x", we can multiply 0.02 and 100 using the distributive property of multiplication, which states that:

a * (b + c) = a * b + a * c

Using this property, we can write:

0.02 * 100 = 0.02 * (50 + 50)

Then, we can distribute the 0.02 to each term inside the parentheses:

0.02 * 100 = 0.02 * 50 + 0.02 * 50

Next, we can simplify each multiplication:

0.02 * 100 = 1 + 1

Finally, we can add the two numbers to get the result:

0.02 * 100 = 2

(a) P(two red marbles) with replacement:The probability of drawing a red marble from a jar with five red marbles and four black marbles is 5/9, as there are five red marbles and nine total marbles. As a result, the probability of selecting two red marbles in a row with replacement is:P(two red marbles with replacement) = (5/9) × (5/9) = 25/81without replacement:When the first marble is removed, there are now only eight marbles remaining in the jar. Because there are only four black marbles in the jar, the probability of drawing a red marble is now 5/8. Therefore, the probability of selecting two red marbles in a row without replacement is:P(two red marbles without replacement) = (5/9) × (5/8) = 25/72(b) P(two black marbles)with replacement:For the first draw, there are four black marbles in the jar and a total of nine marbles. Therefore, the probability of drawing a black marble on the first draw is 4/9. Since the first marble was not removed, there are now eight marbles in the jar, including three black ones, and there are a total of nine marbles. Therefore, the probability of selecting another black marble is 3/9 or 1/3.

The probability of drawing two black marbles in a row with replacement is:P(two black marbles with replacement) = (4/9) × (1/3) = 4/27without replacement:Since the first marble was removed, there are only eight marbles in the jar, and there are four black ones. Therefore, the probability of selecting a black marble is 4/8 or 1/2. When the first black marble is removed, there are only seven marbles left, including three black ones. Therefore, the probability of selecting another black marble is 3/7. As a result, the probability of drawing two black marbles in a row without replacement is:P(two black marbles without replacement) = (4/9) × (3/7) = 12/63(c) P(one red and one black marble)with replacement:When one red and one black marble are selected with replacement, there are nine marbles in the jar for each draw. The probability of selecting one red and one black marble in a row is:P(one red and one black marble with replacement) = 2 × (5/9) × (4/9) = 40/81without replacement:Since there are five red and four black marbles in the jar, the probability of selecting a red marble first is 5/9. Once the red marble has been drawn and removed, there are only eight marbles remaining, including four black ones. As a result, the probability of selecting a black marble is 4/8 or 1/2.

As a result, the probability of drawing one red and one black marble without replacement is:P(one red and one black marble without replacement) = (5/9) × (4/8) + (4/9) × (5/8) = 20/36 + 20/36 = 10/18 = 5/9(d) P(red on the first draw and black on the second draw)with replacement:There are nine marbles in the jar for each draw. The probability of selecting a red marble first is 5/9. When the red marble is returned to the jar, there are still nine marbles in the jar, but now there are only four black marbles. The probability of selecting a black marble on the second draw is 4/9. As a result, the probability of drawing a red marble first and a black marble second with replacement is:P(red on the first draw and black on the second draw with replacement) = (5/9) × (4/9) = 20/81without replacement:Since there are five red and four black marbles in the jar, the probability of selecting a red marble first is 5/9.

4/7+1/8+1/3 prime number​

Answers

Since 7 is the smallest integer that divides 173/168, we can conclude that the sum is not a prime number.

How to solve?

To add the fractions 4/7, 1/8, and 1/3, we need to find a common denominator.

The prime factorization of 7 is 7, the prime factorization of 8 is 2²3, and the prime factorization of 3 is 3. The least common multiple (LCM) of these three numbers is 7× 2²3× 3 = 168.

So, we can rewrite the fractions with the common denominator of 168:

4/7 = 96/168

1/8 = 21/168

1/3 = 56/168

Now we can add these fractions:

96/168 + 21/168 + 56/168 = 173/168

To check if this sum is a prime number, we can use trial division by checking all the integers between 2 and the√ of 173/168 (which is approximately 1.053):

2 does not divide 173/168

3 does not divide 173/168

4 does not divide 173/168

5 does not divide 173/168

6 does not divide 173/168

7 divides 173/168 (24 times)

8 does not divide 173/168

9 does not divide 173/168

...

Since 7 is the smallest integer that divides 173/168, we can conclude that the sum is not a prime number.

How to do matrix multiplication in MIPS?

Answers

To perform matrix multiplication in MIPS, we can use nested loops to iterate over the rows and columns of the matrices.

The outer loop iterates over the rows of the first matrix, while the inner loop iterates over the columns of the second matrix. We then perform the dot product of the corresponding row and column, which involves multiplying the elements and summing the products.

To perform multiplication efficiently, we can use MIPS registers to store intermediate values and avoid accessing memory unnecessarily. We can also use assembly instructions like "lw" and "sw" to load and store values from memory, and "add" and "mul" to perform arithmetic operations.

In summary, matrix multiplication in MIPS involves nested loops, efficient use of registers and assembly instructions, and arithmetic operations.

Show that, the sum of an infinite arithmetic progressive sequence with a positive common difference
is +∞

Answers

Answer:

Show that, the sum of an infinite arithmetic progressive sequence with a positive common difference

is +∞

Step-by-step explanation:

To show that the sum of an infinite arithmetic progressive sequence with a positive common difference is +∞, we can use the formula for the sum of the first n terms of an arithmetic sequence:

Sn = n/2 [2a + (n-1)d]

where a is the first term, d is the common difference, and n is the number of terms in the sequence.

Now, if we let n approach infinity, the sum of the first n terms of the sequence will also approach infinity. This can be seen by looking at the term (n-1)d in the formula, which grows without bound as n becomes larger and larger.

In other words, as we add more and more terms to the sequence, each term gets larger by a fixed amount (the common difference d), and so the sum of the sequence increases without bound. Therefore, the sum of an infinite arithmetic progressive sequence with a positive common difference is +∞.

Answers

Therefore, the difference in the price of 300 cm of ribbon between shop A and shop B is £1.20.

What is equation?

In mathematics, an equation is a statement that two expressions are equal. It usually contains one or more variables, which are typically represented by letters, and may contain constants and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. An equation can be true or false depending on the values of the variables. Solving an equation means finding the values of the variables that make the equation true.

Here,

To find the difference in price between the two shops, we need to first calculate the cost per centimeter of ribbon for each shop:

Shop A: £1.68 / 140 cm = £0.012 per cm

Shop B: £1.72 / 215 cm = £0.008 per cm

Now, we can calculate the cost of 300 cm of ribbon at each shop:

Shop A: 300 cm x £0.012 per cm = £3.60

Shop B: 300 cm x £0.008 per cm = £2.40

The difference in price between the two shops for 300 cm of ribbon is:

£3.60 - £2.40 = £1.20

B. there is a low probability that the obtained results could be due to random error.C. the independent variable fails to have an effect on the dependent variable.D. the researcher is convinced that the variable is ineffective in causing changes in behavior.

Answers

The null hypothesis is rejected whenever "there is a low probability that the obtained results could be due to random error." The correct answer is Option B.

What is the null hypothesis?

The null hypothesis is a statistical hypothesis used to test the difference between two sample data groups. The null hypothesis is the hypothesis that the sample statistics are not significantly different. Any significant differences between the sample data are seen as supporting the alternative hypothesis.

A null hypothesis is often expressed as "no difference," "no correlation," or "no significant effect." For example, the null hypothesis for an experiment comparing two groups of people could be "there is no difference between the two groups." When the null hypothesis is rejected, it means that the results of the experiment are statistically significant, and the alternative hypothesis is supported.

Therefore, the null hypothesis is rejected whenever there is a low probability that the obtained results could be due to random error.

Therefore, we estimate that about 7 sixth graders should be chosen to create a representative sample, given that 9 seventh graders were chosen.

What is statistics?

Statistics is a branch of mathematics that involves the collection, analysis, interpretation, presentation, and organization of data. It provides methods for summarizing and describing data, making inferences about populations based on samples, and testing hypotheses. Statistics is used in many fields, such as business, economics, health care, social sciences, engineering, and more, to make decisions and draw conclusions based on data. Some common techniques used in statistics include descriptive statistics (e.g., mean, median, mode, standard deviation), probability theory, hypothesis testing, regression analysis, and sampling methods.

Here,

To estimate the number of sixth graders that should be chosen to create a representative sample, we can use the proportion of seventh graders in the sample and assume that the proportions of each grade in the sample should match the proportions in the population. We know that the sample contains 9 seventh graders, but we don't know the total size of the sample yet. We can use the following formula to estimate the sample size:

sample proportion = population proportion

where

sample proportion = number of seventh graders in the sample / total sample size

population proportion = number of seventh graders in the population / total population size

We can plug in the values we know:

9 / total sample size = 180 / (160 + 180 + 140)

Simplifying the right-hand side:

9 / total sample size = 0.4

Multiplying both sides by total sample size and simplifying:

total sample size = 9 / 0.4

total sample size ≈ 22.5

This means that the sample size should be about 22.5 students. Since we can't choose a fractional number of students, we should round up to the nearest whole number, giving a total sample size of 23 students.

To estimate the number of sixth graders in the sample, we can use the proportion of sixth graders in the population and assume that the proportion should be the same in the sample:

number of sixth graders in the sample / total sample size = 160 / (160 + 180 + 140)

Simplifying the right-hand side:

number of sixth graders in the sample / total sample size = 0.32

Multiplying both sides by total sample size and simplifying:

number of sixth graders in the sample = 0.32 * 23

number of sixth graders in the sample ≈ 7
