Answer:  (7) 7.0              (8) 17.3            (9) 64.7°

Step-by-step explanation:

Law of Cosines is: a² = b² + c² - 2bc · cos A

                         or: b² = a² + c² - 2ac · cos B

                         or: c² = a² + b² - 2ab · cos C

7) b = 4, c = 10, ∠A = 34

a² = b² + c² - 2bc · cos A

   = 4² + 10² - 2(4)(10) · cos 34°

   = 16 + 100 - 80 (0.829)

   = 116 - 66.323

   = 49.677

a = [tex]\sqrt{49.677}[/tex]

a = 7.0

8) a = 11, b = 8, ∠C = 131

c² = a² + b² - 2ab · cos C

   = 11² + 8² - 2(11)(8) · cos 131°

   = 121 + 64 - 176 (-0.656)

   = 185 + 115

   = 300

c = [tex]\sqrt{300}[/tex]

c = 17.3

9) a = 10.5, b = 5.9, c = 9.6

9.6² = 10.5² + 5.9² - 2(10.5)(5.9) · cos C

92.16 = 110.25 + 34.81 - 2(10.5)(5.9) · cos C

92.16 = 145.06 - 123.9 cos C

-52.9 = -123.9 cos C

0.427 = cos C

cos⁻¹ (0.427) = C

64.7° = C

Answer:

1/18

Step-by-step explanation:

We are considering that we have 2 dices with 6 faces each (so, the probability to getting any face in any dish is 1/6). To get an 11, we only have two ways to obtain it:

Dice 1= 6 and Dice 2 =5 or Dice 1= 5 and Dice 2 =6

So, the probability of the event is given as:

P(Dice1=5 ∧ Dice2=6) ∪ P(Dice1=6 ∧ Dice2=5) = P(Dice1=5) x P(Dice2=6) + P(Dice1=6) x P(Dice2=5) = 1/6 x 1/6 + 1/6 x 1/6 = 1/36 + 1/36 = 2/36 = 1/18.

As 1/18 = 0,055, and 0,055 > 0,05, we consider the event as not significative (according to the definition of significance in the sentence).

Answer:

1. They are all red. 2. There is no possible way to come to a conclusion

Step-by-step explanation:

If there is a 100% chance you will draw a red marble, they all have to be red or it would not be a 100% chance.

We can't conclude how many marbles are in the bag because the question states nothing about how many marbles there are.

Answer:

The only prime number is 19

Okay, I am going to answer this question personally.

Suppose we want to choose 3 colors, without replacement, from the red, blue, green, and purple.

(a) How many ways can this be done, if the order of the choices is taken into consideration?  

(b) How many ways can this be done, if the order of the choices is not taken into consideration?

Answer

(a) 6 choices

(b) 3 Choices

Given:

3 Colors

Order of choice : Red, Blue, Green

(a) Order of the choices taken into consideration :

When we are picking  the first colour there are 3 color choice.

When we are picking second colour there are 2 choice and so on.

Therefore, total choices are = 3*2 = 6 choices

(b) Order of the choices not taken into consideration :

When to take this option we choose as   and the remove the duplicates

Therefore, choices are 3 Choices

Mean = sum of all numbers / 20 = 1669 / 20 = 83.45

Standard deviation = 7.86

Z-score = -1

So...

Z = (x - mean) / standard deviation

x = Z * standard deviation + mean = -1 * 7.86 + 83.45 = 75.59

Rounded: 75.6

Answer:

[tex]-2\frac{7}{20}[/tex]

Step-by-step explanation:

Given the following question:

[tex]3\frac{2}{5} -5\frac{3}{4}[/tex]

To find the answer we first need to convert the mixed numbers into improper fractions, find the common denominator, subtract the denominators, and of course convert the improper fraction back into a mixed number.

[tex]3\frac{2}{5} -5\frac{3}{4}[/tex]
[tex]3\frac{2}{5}=5\times3=15+2=17=\frac{17}{5}[/tex]
[tex]5\frac{3}{4} =4\times5=20+3=23=\frac{23}{4}[/tex]
[tex]\frac{17}{5} -\frac{23}{4}[/tex]

Find the common denominator:
[tex]CD=20[/tex]
[tex]\frac{17}{5} \times4=\frac{68}{20}[/tex]
[tex]\frac{23}{4} \times5=\frac{115}{20}[/tex]
[tex]\frac{68}{20} -\frac{115}{20}[/tex]
[tex]68-115=-47=-\frac{47}{20}[/tex]
[tex]=-\frac{47}{20}[/tex]

Convert the improper fraction into a mixed number:
[tex]-\frac{48}{20}[/tex]
[tex]-\frac{47}{20} =47\div20=-2\frac{7}{20}[/tex]
[tex]=-2\frac{7}{20}[/tex]

Your answer is "-2 7/20."

Hope this helps.

[tex]2\frac{7}{20}[/tex] is the mixed number we get by subtracting  [tex]3\frac{2}{5}[/tex] from [tex]5\frac{3}{4}[/tex].

To subtract [tex]3\frac{2}{5}[/tex] from [tex]5\frac{3}{4}[/tex], we first need to convert both mixed numbers to improper fractions.

[tex]5\frac{3}{4}[/tex] = (4 × 5 + 3) / 4 = 23/4

[tex]3\frac{2}{5}[/tex] = (5 × 3 + 2) / 5 = 17/5

Now we can subtract the two fractions:

23/4 - 17/5

To subtract fractions, we need to have a common denominator.

The common denominator for 4 and 5 is 20.

We'll convert both fractions to have a denominator of 20:

23/4 = (23 × 5) / (4 × 5) = 115/20

17/5 = (17 × 4) / (5 × 4) = 68/20

Now we can subtract the fractions:

115/20 - 68/20

= (115 - 68) / 20

= 47/20

Answer:

7.79

Step-by-step explanation:

A hundredth is the second number after the decimal. For example, in the number 100.234, the "3" would be the hundredth, the "2" would be the tenth, and the "4" would be the thousandth.

To round to the nearest hundredth, you have to look at the thousandth because when rounding, you look at the next number to decide whether to round up or down.

Since 8 is in the thousandth place in this question, and 8 is bigger than 5, you round up. So, you round the "8" in the hundredths place up to 9.

Therefore, you get 7.79.

Answer:

y = -8x + 54

Step-by-step explanation:

Since the lines are parallel, their slopes are the same, leaving you with y = -8x.

That equation at x = 7 would make y -56, but we want it to be -2. Therefore we add a 54 in the end, leaving you with y = -8x + 54.
