We are given with
P(pop quiz) = 60%
P(not do homework) = 85%

And the condition that
P (pop quiz and do homework) > 5%

So,
P (pop quiz) x P (do homework)
P (pop quiz) x ( 1 - P (not do homework) )
60% x ( 1 - 85%)

The result is greater than five percent so he will not do his homework.

At 12 noon in anchorage Alaska Janice noticed that the temperature outside was 12
Alisiya [41]
I assume that you want to know the temperature at a certain timing.
Well, you know that at 12:00 pm, the temperature was 12 F and that it decreases by a steady rate of 2 F each hour.

This means that at 1:00 pm, the temperature was 12-2 = 10 F
At 2:00 pm, the temperature was 10-2 = 8 F
At 3:00 pm, it was 8-2 = 6 F
.......and so on

You can follow this sequence to the timing you are looking for.
