Answer:

[tex]s = 0.0394[/tex]

Step-by-step explanation:

Given:

0.612 0.523  0.606 0.631  0.584  0.592  0.644  0.597  0.639  0.607  0.564  0.673

Required

Calculate the sample standard deviation

First, calculate the mean

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\bar x = \frac{0.612 +0.523 +0.606 +0.631+ 0.584 + 0.592+ 0.644 +0.597 +0.639 +0.607 +0.564+ 0.673}{12}[/tex]

[tex]\bar x = \frac{7.272}{12}[/tex]

[tex]\bar x = 0.606[/tex]

The sample standard deviation is then calculated using:

[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]

[tex]\sum (x - \bar x)^2 = (0.612 -0.606)^2+(0.523 -0.606)^2+(0.606 -0.606)^2+(0.631 -0.606)^2+(0.584 -0.606)^2+(0.592 -0.606)^2+(0.644 -0.606)^2+(0.597 -0.606)^2+(0.639 -0.606)^2+(0.607 -0.606)^2+(0.564 -0.606)^2+(0.673 -0.606)^2[/tex]

[tex]\sum (x - \bar x)^2 = 0.017098[/tex]

So, we have:

[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]

[tex]s = \sqrt{\frac{0.017098}{12-1}}[/tex]

[tex]s = \sqrt{\frac{0.017098}{11}}[/tex]

[tex]s = \sqrt{0.00155436363}[/tex]

[tex]s = 0.0394[/tex] -- approximated

Step-by-step explanation:

∠VMC=180-90-48

          =42

∠PMV=180-22-90-42

         =26

5/sin48=VM/sin90

VM=6.728( correct to three decimal places)

6.728/sin22=PV/sin26

PV=7.873( correct to three decimal places)

Answer:

I think (25, 20) is your answer. hope it helps.

The equivalent ratio to (5, 4) is (25, 20). Therefore, option C is the correct answer.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

The coordinates from graph are (5, 4), (10, 8), (15, 12) and (20, 16).

Equivalent ratios are ratios that can be simplified to the same value by dividing both the values by a common fraction.

Here,

(5, 4)=5(5, 4)=(25, 20)

(10, 8)=2(10, 8)=(20, 16)

(15, 12)=2(15, 12)=(30, 24)

(20, 16)

The equivalent ratio to (5, 4) is (25, 20). Therefore, option C is the correct answer.

Answer:

1 3/8 inches

Step-by-step explanation:

Total Length after adding 2 meteors of equal length = 16 inches

Let the length of the added meteor = x

To obtain the total length, we sum of each meteror multiplied by its frequency is obtained ;

(2/8)(1)+(3/8)(3)+(4/8)(2)+(6/8)(2)+(10/8)(1)+(11/8)(2)+(14/8)(2)+(15/8)(1) + 2x = 16

13.25 + 2x = 16

13.25 + 2x = 16

2x = 16 - 13.25

2x = 2.75

x = 1.375

1.375 = 1 3/8

Answer:

It will take 24 minutes before they are on the same problem.

Step-by-step explanation:

Caroline is on number 12 and can solve 1 math problem in 1.5 minutes.

Per minute, she solved [tex]\frac{1}{1.5} = \frac{2}{3}[/tex] of a problem. So, after t minutes, she will be on the problem:

[tex]Ca(t) = 12 + \frac{2t}{3}[/tex]

Chase is on number 16 and can solve 1 math problem in 2 minutes.

Per minute, he solved [tex]\frac{1}{2}[/tex] of a problem. So, after t minutes, he will be on the problem:

[tex]Ch(t) = 16 + \frac{t}{2}[/tex]

How many minutes will it take before they are on the same problem?​

This is t for which:

[tex]Ca(t) = Ch(t)[/tex]

So

[tex]12 + \frac{2t}{3} = 16 + \frac{t}{2}[/tex]

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

[tex]\frac{4t-3t}{6} = 4[/tex]

[tex]\frac{t}{6} = 4[/tex]

[tex]t = 24[/tex]

It will take 24 minutes before they are on the same problem.

Given:

A figure of dilation and the center of dilation is O.

To find:

The value of y.

Solution:

The distance between center and vertex of image (d') is proportional to the distance between center and the corresponding vertex of original figure (d).

[tex]d'\propto d[/tex]

[tex]d'=kd[/tex]

[tex]\dfrac{d'}{d}=k[/tex]

Where, k is the scale factor or constant of proportionality.

So, the scale factor for the given dilation is

[tex]k=\dfrac{OB'}{OB}[/tex]

[tex]k=\dfrac{36}{16}[/tex]

[tex]k=\dfrac{9}{4}[/tex]

We know that,

[tex]k=\dfrac{\text{Side length of image}}{\text{Corresponding side length of original figure}}[/tex]

[tex]\dfrac{9}{4}=\dfrac{A'C'}{AC}[/tex]

[tex]\dfrac{9}{4}=\dfrac{27}{y}[/tex]

[tex]9\times y=27\times 4[/tex]

Divide both sides by 9.

[tex]y=\dfrac{27\times 4}{9}[/tex]

[tex]y=3\times 4[/tex]

[tex]y=12[/tex]

Therefore, the value of y is 12.

15 * 10 = 150; 150 * 2 = 300

5 * 10 = 50; 50 * 2 = 100

5 * 15 = 75; 75 * 2 = 150

300 + 100 + 150 = 550

Answer:

50 students in total or X=50

Step-by-step explanation: 12 is 24% of X

We can make this into a box-like figure

12  24

X   100          X is the missing number

We then multiply 12 by 100 which equals to 1,200.

We then divided the 1,200 by 24, this results in your X which equals to 50.

X=50 students

112 B

Step-by-step explanation:

The number of coins Sally and Bill will be 64 and 112 and the ratio will remain the same.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that Salley collected 32 coins, the ratio of Sally’s coins to Bill’s coins is 4: 7, and Sally and Bill each double the number of coins they have now.

Suppose the number of coins that Sally and Bill will be 4x and 7x respectively.

If Sally has the 32 coins and if she doubles the coins she has 64.

4x  = 64

x =16

Sally’s coins,

4x = 4 × 16 =64

Bill’s coins,

7x =7× 16 = 112

Thus, the number of coins Sally and Bill will be 64 and 112 and the ratio will remain the same.

I think the question is asking for the ratio to be simplified, if so then that's what the answer is.

Answer:

75

Step-by-step explanation:

12 : 50 :: 18 : x

In proportion, Product of extremes  = Product of means

                       12 * x = 50*18

                             [tex]x =\frac{50*18}{12}=\frac{50*3}{2}[/tex]
