At a store, customers are randomly selected to participate in a survey.
On Friday, there were 500 customers at the store. Of those, 90 were
selected to participate in the survey. On Saturday, the store manager
wants 126 people to participate in the survey.
Part A: If the probability of being selected to participate in the survey
on Saturday is the same as it was on Friday, how many total
customers must enter the store on Saturday?
Part B: If 25% of the customers who completed the survey were
female, how many total females completed the survey?

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
