C=r(5-d)/y We need to solve for d.

GrogVix [38]

Answer:

5-Cy/r = d

Step-by-step explanation:

C=r(5-d)/y

Multiply each side by y

Cy=r(5-d)/y *y

Cy=r(5-d)

Divide each side by r

Cy/r=r(5-d)/r

Cy/r=(5-d)

Subtract 5 from each side

Cy/r - 5 = 5-d-5

Cy/r - 5 = -d

Multiply by -1

-Cy/r + 5 = d

5-Cy/r = d

A random sample of 10 subjects have weights with a standard deviation of 11.0482 kg. What is the variance of their weights? Be

Paladinen [302]

Answer:

The variance is 122.0627 kg

Step-by-step explanation:

The square of the standard deviation of a distribution gives us the variance.

If a random sample of 10 subjects have weights with a standard deviation of 11.0482 kg.

Then the standard deviation is

${ \sigma} = 11.0482$

To get the variance, we square both sides to get;

${ \sigma}^{2} = 11.0482^{2}$

This implies that,

${ \sigma}^{2} = 122.0627kg$
