Of the following individuals, which person is the most likely to engage in leisure-time physical activity?
a. a newly retired township firefighter
b. a young, single mother
c. a young man with a white-collar job
d. an east coast grandmother

The correct answer is C)  A young man with a white-collar job

A young man with a white-collar job is the most likely to engage in leisure-time physical activity because he does not have enough responsibilities. So, in order to pass his time he will engage himself in a leisure-time physical activity.

Whereas, a newly retired township firefighter is old enough to participate in physical activities. On the other hand, a young, single mother will have other responsibilities so she will have no time to engage in physical activity.  

Similarly, a grandmother is old enough so she will not participate in any physical activity.

Thus, option C) is the right answer.

0.5 < x < 3

or (0.5, 3)

Step-by-step explanation:

-16t² + 56t + 2 = 26

Subtract both sides by 26

-16t² + 56t + 2 = 26

                 -26   -26

-16t² + 56t - 24 = 0

Divide both sides by -8 to simplify

(-16t² + 56t - 24)/8 = 0/8

2t² - 7t + 3 = 0

Factor

(x - 3)(2x - 1) = 0

Do this to find the x's

x - 3 = 0

 + 3  +3

x = 3

2x - 1 = 0

    + 1  + 1

2x = 1

2x/2 = 1/2

x = 0.5

0.5 < x < 3

This means the intervals will have to be between 0.5 and 3 seconds
