A random sample of 10 subjects have weights with a standard deviation of 13.5620 kg. What is the variance of their weights? Be sure to include the appropriate units with the result.

183.927844 kg²

Step-by-step explanation:

Calculation for the weight variance:

Given that s =13.5620 kg

The Variance will be the square of the Standard Deviation

S²=13.5620 kg²

S²=183.927844

The units of the variance will be the units of the Standard Deviation Squared which is Kg²

Therefore the variance of their weight will be:

183.927844 kg²

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
