SCORPION-xisa [38]

Answer:

6 hours

Step-by-step explanation:

Let

x----> the number of hours worked at the donut shop

y----> the number of hours worked at the school bookstore

we know that

x+y=20

x=20-y -----> equation A

10.25x+8.75y=196 -----> equation B

Substitute equation A in equation B and solve for y

10.25(20-y)+8.75y=196

205-10.25y+8.75y=196

10.25y-8.75y=205-196

1.5y=9

y=6 hours at the school bookstore

Harlamova29_29 [7]

Answer:

Option C is the correct one

Step-by-step explanation:

The events are independent because you are selecting the students randomly and how much they like rap music does not depend on the results on the other students. However, in each event of the binomial distribution there are two possible outcomes: success and fail. In this experiment there are 10 possible results for each event, therefore the distribution inst binomial. The correct answer therefore is C.
