The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%
<h3>
How to find the probability?</h3>
We know that roughly 75% of the students take the bus, then, if we select a student at random.
- There is a probability of 0.75 that the student takes the bus.
- There is a probability of 0.25 that the student does not take the bus.
The probability that at most 8 out of 9 students take the bus, is equal to one minus the probability of the 9 taking the bus, which is:
p = (0.75)^9 = 0.075
Then we have:
P = 1 - 0.075 = 0.925
The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

Step-by-step explanation:
Answer:
9 inches
Step-by-step explanation:
Perimeter of equilateral triangle = 3x
Perimeter of square = 4x
3(x + 6) = 9 + 4x
3x + 18 = 9 + 4x
-x = -9
x = 9
Answer:
Monthly Expense = $270.83
Step-by-step explanation:
The semi-annual premium is paid twice a year so,
Automobile insurance premium for whole year = 650*2
= $1300
Monthly premium will be paid 12 times a year so,
Health insurance premium for whole year = 125*12 = $1500
Annual premium is only paid once a year.
So adding all the premiums will give us the total premiums for whole year.
Total amount of premium for a year = $1300+$1500+$450
= $3250
The premium amount for whole year is $3250. To find the monthly expense, we will divide it by 12.
So monthly expense is:
= 3250/12
= $270.83 ..
