The owner of a fitness center conducted a survey using 20 people at the center, selected at random. Each person was given 30 many push-ups as possible, and 30 seconds to do as many sit-ups as possible. The data is shown in the graph. Comparison of Push-Ups and Sit-Ups Number of Sit-Ups 15+ 10 5 = 1 person 0 2 4 6 8 10 12 14 16 18 20 Number of Push-Ups Which two statements correctly describe the data? A. There is a cluster of data at about 9 push-ups and 15 sit-ups. B. Most people in the survey can do more sit-ups than push-ups. C. The data shows no association between the number of push-ups and sit-ups a person can do. D. The data shows a negative association between the number of push-ups and sit-ups a person can do.

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

the answer would be c:   ax + b = ax + c
