Please help and give a reasonable answer.
8 7 8 9 8.5 7.5 7 6.5 7 7.5 8.5 9 8.5 8 13. Mrs. Bergstedt's class is getting a new student. They want to predict the shoe size of the student. They ask all the girls to record their shoe sizes. Which measure of center should they use to make their prediction and what should be their prediction? A) the mean and they should predict size 8 B) the mean and they should predict size 7 C) the mean and they should predict size 8.5 D) the median and they should predict size 8

the median and they should predict size 8

Step-by-step explanation:

It is this answer because if you put the numbers in order from least to greatest and then start to find the median you will get two answers for the median and the numbers you should get are two 8 so then you add the two 8's up and then you get 16 so then you divide it by 2 and you will get 8 and that is your answer.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
