75 supermarkets are surveyed to determine which brands of detergent they sell. All sell at least one of brands A, B, or C. 55 sell brand A, 57 sell brand B, and 50 sell brand C. 33 supermarkets sell both A and C, while 17 supermarkets sell both A and B but not C. 22 supermarkets sell all three brands. Construct a Venn diagram which represents this situation. Use this diagram to determine how many supermarkets sell: a) both A and C but not B
b) at least two of these brands.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
