Answer:
P(odd number) = 0.5
Step-by-step explanation:
There are 90 members in the set (10, 11, 12, .. , 97, 98, 99)
When we have an even number of consecutive numbers, the number of even numbers equals the number of odd numbers. This means that half of the numbers in this set are even and half of them are odd.
So the probability of P(odd number) = 0.5
Answer:
8 minutes
Step-by-step explanation:
The amount in the glass after m minutes can be described by ...
a = 4 + 3/2m
We want to find m when a=16, so ...
16 = 4 + 3/2m
12 = 3/2m . . . . . subtract 4
8 = m . . . . . . . . . multiply by 2/3
It will take 8 minutes to fill the glass.
The answer is 7 3/4 inches.
