Answer:
B) 10 visits
Step-by-step explanation:
Let the number of visits be x.
Pool A cost: 1x + 40 = x + 40
Pool B cost: 5x
Set the two costs equal and solve for x.
x + 40 = 5x
Subtract 5x from both sides. Subtract 40 from both sides.
-4x = -40
Divide both sides by -4.
x = 10
Answer: B) 10 visits
Answer:
The probability that a randomly selected American adult takes multivitamins regularly and works out regularly is 0.103
Step-by-step explanation:
p(Americans adults take multivitamins regularly) = 50% = 0.50
p(American adults work out regularly) = 20.6 = 0.206
p(Americans adults take multivitamins regularly and American adults work out regularly) = 0.50* 0.206 = 0.103
Thus, p(Americans adults take multivitamins regularly and American adults work out regularly) = 0.103
