Sport Chek conducts customer satisfaction surveys by having its customers complete questionnaires regarding their customer service experience. Their computer system automatically sends surveys to customers who spend more than $100 at their store. What type of bias might result? a) Response Bias
b) Sampling Bias
c) Both response bias and sampling bias
d) Neither response bias or sampling bias

b

Step-by-step explanation:

Because only the customers who spend more than $100 get to complete the form. The other customers wont be able to complete it(people who spent less than $100). thats why the answer would be sampling bias.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
