Answer:

C = 5n + 4f + 15b

Answer:

Bus vs Highway: Houston

Let's start by finding out how many people took the bus.

If the number of people who took the highway is x, then the number of people who took the bus is 1.5x (since it's one and a half times the number of people who took the highway).

We know that the total number of people who traveled to Houston is 31,426, so we can write an equation:

x + 1.5x = 31,426

Simplifying the equation:

2.5x = 31,426

Dividing both sides by 2.5:

x = 12,570.4

Since we can't have a fraction of a person, we can round this down to 12,570.

Now we can find the number of people who took the bus:

1.5x = 1.5(12,570) = 18,855

To find out how many more people took the bus, we can subtract the number of people who took the highway from the number of people who took the bus:

18,855 - 12,570 = 6,285

Therefore, 6,285 more people took the bus.

Answer: 77/6 or 12 5/6

Step-by-step explanation:

To solve this subtraction problem, we need to first convert the mixed numbers to improper fractions.

20 1/3 can be written as:

20 + 1/3 = 60/3 + 1/3 = 61/3

7 1/2 can be written as:

7 + 1/2 = 14/2 + 1/2 = 15/2

So, the problem becomes:

61/3 - 15/2

To subtract two fractions, we need to have a common denominator. The smallest number that both 3 and 2 divide into is 6. So we will convert both fractions to have a denominator of 6.

61/3 = (61/3) * (2/2) = 122/6

15/2 = (15/2) * (3/3) = 45/6

Now we can subtract the two fractions:

122/6 - 45/6 = 77/6

So, the final answer is:

20 1/3 - 7 1/2 = 77/6 or 12 5/6 (as a mixed number)

The equation 32 - 3x + 13 = 0 can be rewritten as 3x = 19. Therefore, x = 19/3. Because x is a real number, the solution to the equation is x = 19/3.

Real numbers are any number that can be expressed as a decimal number or a fraction. This includes the natural numbers (1,2,3,4, etc.), the negative numbers (-1,-2,-3, etc.), the rational numbers (fractions, such as 1/2, 3/4, etc.), and the irrational numbers (numbers that cannot be expressed as a fraction, such as pi, square root of 2, etc.). Real numbers can be manipulated with basic arithmetic operations such as addition, subtraction, multiplication, and division. Real numbers have an infinite number of decimal places, making them useful for measuring physical quantities such as time, distance, and temperature.

Expressing this answer in the form a + bi, where a and b are real numbers, gives the solution a = 19/3 and b = 0. Therefore, the answer is 19/3 + 0i = 19/3.

The value of the probability is 0.3125 and this is proved by the calulations below

The probability of getting exactly 3 heads in 5 coin tosses can be calculated by multiplying the probability of one specific combination of 3 heads and 2 tails by the number of possible combinations.

The probability of one specific combination, for example HHTTT, is (1/2)^5 = 1/32, because each toss has a 1/2 chance of being a head or a tail.

There are 5C3 = 10 possible combinations of 3 heads and 2 tails in 5 tosses.

For example: HHTTT, HTHTT, HTTHT, HTHHT, TTHHH, etc.

Therefore, the probability of getting exactly 3 heads is:

Probability = 10 * (1/32)

Probability = 10/32

Probability = 0.3125.

Hence, the value of the probability is 0.3125.

So first of all u have to convert the metres into centimetres. After the conversation draw the map of both in centimetres and your map is done. The question is answered

Answer:

Determine the dimensions of the room: Measure the length and width of the room you want to draw a floor plan for using a tape measure. Record these measurements in meters.

Choose a scale: Since you want to use a scale of 1cm to 0.5m, you need to convert your measurements from meters to centimeters. For example, if your room measures 6 meters by 4 meters, you need to multiply each measurement by 100 to get 600cm by 400cm. Then, divide each measurement by 2 to get your scale measurement. In this case, your floor plan will be 300cm by 200cm.

Draw a rough sketch: Using a pencil and graph paper, draw a rough sketch of the room's shape based on the dimensions you have recorded.

Add doors and windows: Using the same scale, add doors and windows to your floor plan. Doors are typically represented by a straight line with an arc on top, while windows are represented by a straight line with a horizontal line through the middle.

Add fixtures and appliances: Add any fixtures and appliances that are permanent to the room, such as sinks, cabinets, and appliances. You can use symbols to represent these items, such as a rectangle for a refrigerator or a triangle for a sink.

Label everything: Finally, label everything on your floor plan using a legible font. This includes the dimensions of the room, the location of doors and windows, and the names of fixtures and appliances.

Step-by-step explanation:

Step-by-step explanation:

Theoretical probabilities can be calculated using the concept of probability. Each student has a 0.5 chance of selecting either List A or List B. Therefore, the probability of getting 27 heads and 33 tails can be calculated as:

P(27 heads and 33 tails) = (60 choose 27) * (0.5)^27 * (0.5)^33 where (60 choose 27) is the number of ways to select 27 students out of 60.

Using a calculator, we can compute the above probability as approximately 0.109. This means that if we were to repeat this experiment many times, we would expect to get 27 heads and 33 tails about 10.9% of the time.

Comparing this theoretical probability to the experimental results, we see that the observed proportion of heads (27/60 = 0.45) is lower than the expected proportion of heads (0.5) and the observed proportion of tails (33/60 = 0.55) is higher than the expected proportion of tails (0.5).

However, it is important to note that due to the random nature of the experiment, we would not expect the exact theoretical probabilities to match the experimental results exactly. In other words, there is always some amount of variation expected in the results. Nonetheless, the experimental results are consistent with the theoretical probabilities, and we can conclude that there is no significant deviation from what we would expect by chance.

We must solve the absolute values first

An absolute value is the numbers distance from zero

So a simplified version of your problem would be

2-1

So your answer is 1

The absolute value of a number is its distance from 0, so |-2| is 2 and |-1| is 1. Substituting these back in, the expression 2 - 1 equals 1.

To evaluate the expression |-2| – |-1|, you first need to understand what the absolute value symbol does. The absolute value of a number is its distance from 0 on the number line, regardless of direction. So, both |-2| and |-1| become positive numbers, as distance is always positive.

Therefore, |-2| equals 2 and |-1| equals 1. If we substitute these values back into the original expression, 2 - 1, the result is 1.

As a result, there is a 90° angle separating each couple of animal residences.

A geometric shape known as an angle is created by two rays that meet at a spot in the middle known as the vertex. The rays are typically depicted as a line section with an arrow pointing in the direction of the ray's extension on one end. When a complete circle is divided into 360 equal parts, each component being one degree, an angle is created that is measured in terms of degrees. The angle created when the radius of a circular equals the length of its arc is measured in radians.

given

A circle that includes the tree, pond, spider web, and bird's nest has been drawn by the photographer, with the camera in its middle. This is due to the fact that each time she rotates the camera anticlockwise, she is actually rotating it around the middle of this circle.

Call the angle between each set of animal residences "x" for simplicity. We can infer the following because the shooter always rotates the camera through the same angle:

Angle from pond to spider's web turned equals x Angle from tree to pond turned equals x

Angle from bird's nest to branch turned equals x

Since the photographer has made a full rotation, the total of these angles must be 360 degrees. Therefore:

x + x + x + x = 360

4x = 360

x = 90

An exponential function can model California's population growth from 1950 to 1980. The predicted population in 2020 is around 43.3 million (43,301,300), assuming exponential growth.

To find an exponential function that models the population, we can use the formula:

P(t) = P0 * e^(rt)

where P0 is the initial population, r is the growth rate, and t is the time in years. We can use the information given to find P0, r, and then plug in t = 0 to find the exponential function.

P0 = 10,586,223 (initial population in 1950)

P(30) = 23,668,562 (population in 1980, 30 years later)

t = 30

P(0) = P0 * e^(0*r) = P0 (population in 1950)

So we have:

23,668,562 = 10,586,223 * e^(30r)

Dividing both sides by 10,586,223:

e^(30r) = 2.234

Taking the natural logarithm of both sides:

30r = ln(2.234)

r = ln(2.234)/30

Now we can use this value of r to find the exponential function:

P(t) = 10,586,223 * e^(t*ln(2.234)/30)

To predict the population in 2020, we can plug in t = 70 (since 2020 is 70 years after 1950) into the function we just found:

P(70) = 10,586,223 * e^(70*ln(2.234)/30) ≈ 43,301,300

Therefore, the predicted population of California in 2020 is approximately 43,301,300.

The equation Av = λv, where v is a non-zero vector, is satisfied by an eigenvector v and an eigenvalue given a square matrix A. In other words, the eigenvector v is multiplied by the matrix A to produce a scalar multiple of v. Due to their role in illuminating the behaviour of linear transformations and differential equation systems, eigenvectors play a crucial role in many branches of mathematics and science. When the eigenvector v is multiplied by A, the eigenvalue indicates how much it is scaled.

The eigenvalue and eigenvector states that, let v be a non-zero eigenvector of A corresponding to the eigenvalue λ.

Then, we have:

Av = λv

Taking transpose on both sides we have:
