Dr. Sharif wants to know whether owning a dog affects the amount of exercise her patients get each week. She surveyed her patients and recorded the average hours of exercise per week of patients who own a dog and of patients who do not own a dog. Which of the following is the best conclusion that can be drawn from the collected data?

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

d

step-by-step explanation:

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
