PLEASE ANSWER ASAP WILL GIVE BRANLIEST TO CORRECT ANSWER The distributions of heights of 1000 men and 1000 women selected at random from the population of a large metropolitan area are shown. Compare the heights of the men and women by comparing the mean and the spread of the data sets.

60% of women are 66 inches tall and 73% 45 inches tall... i think...

Answer

There is more variation in height for men, the mean is 70. The women's height has less variation, the mean is 65.

Explanation

(how to find a mean: The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.) That is just what I did, I have no clue if the answer is correct, im just trying to help.

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
