The ages (in years) and weights (in pounds) of all wide receivers for a football team are listed. Find the coefficient of variat

IceJOKER [234]

Answer:

The coefficient of variation for the weight and age are 5.9% and 10.6%.

Step-by-step explanation:

The coefficient of variation (CV) is well defined as the ratio of the standard deviation to the mean. It exhibits the degree of variation in association to the mean of the population.

The formula to compute the coefficient of variation is:

$CV=\frac{\sigma}{\mu}\times 100\%$

Here σ = standard deviation and µ = mean.

Compute the mean and standard deviations of the two data set in Excel using the following functions.

Mean=AVERAGE()

Standard deviation=STDEV.S()

Consider the Excel sheet attached.

The mean and standard deviation of weight are:

Mean = 202, Standard deviation = 11.87

And the mean and standard deviation of weight are:

Mean = 25.88, Standard deviation = 2.75

Compute the coefficient of variation for the weight as follows:

$CV_{weight}=\frac{\sigma}{\mu}\times 100\%$

$=\frac{11.87}{202}\times 100\%\\\\=5.87624\\\\=5.9\%$

Compute the coefficient of variation for the age as follows:

$CV_{age}=\frac{\sigma}{\mu}\times 100\%$

$=\frac{2.75}{25.88}\times 100\%\\\\=10.62597\\\\=10.6\%$

Thus, the coefficient of variation for the weight and age are 5.9% and 10.6%.

(2) You have $20 and are able to save $15.50 a month. Your friend has $88 and is able to save $7 a month. Enter the number of mo

S_A_V [24]

Answer:

8 months is the answer.

Step-by-step explanation:

20 + (15.50 x 8) = 144

88 + (7 x 8) = 144

How I found the answer was by plugging in numbers where 8 was until they both matched.

HELP ASAP PLEASE <br> IN SPANISH BUT ITS FINDING AREA

kicyunya [14]

Answer:

Area of the square:

12 x 16 = 192

Area of the semi circle on top:

16 - 8 = 8 is your diameter

half of 8 is 4.

I got 8 from adding the two fours on the side of that semi circle on top.

4^2 x 3.14

16 x 3.14 = 50.24

50.24 divided by 2 = 25.12

Area of the semi circle on the side:

12 - 8 = 4

4 is your diameter and half of that which would be your radius is:

2 so

2^2 x 3.14

4 x 3.14 = 12.56

12.56 divided by 2 = 6.28

Now we are going to add all the areas:

192 + 25.12 + 6.28 = 223.4 is your answer
