yarga [219]

Answer: $\text{Mean length}=590.5\ mm\\\\\text{Variance of the lengths}=0.03\ mm$

Step-by-step explanation:

The mean and variance of a continuous uniform distribution function with parameters m and n is given by :-

$\text{Mean=}\dfrac{m+n}{2}\\\\\text{Variance}=\dfrac{(n-m)^2}{12}$

Given : $m=590.2\ \ \ n=590.80$

$\text{Then, Mean=}\dfrac{590.2+590.8}{2}=590.5\ mm\\\\\text{Variance}=\dfrac{(590.8-590.2)^2}{12}=0.03\ mm$

The scatter plot shows the relationship between the time since Martha has left work and the distance she is from home.

telo118 [61]

The correct answer is A.

The independent variable is time and the dependent variable is distance; this means the slope tells us how far she goes per minute. Since the slope is negative and we are referring to her distance from her house, this means the distance from her house is decreasing, which means she is getting closer to her house.
