5% of 9 is 0.45.
Why? Well 0.45 times 20 is equal to 9, and 100 divided by 20 is 5 therefore 5 percent.
Answer: 3a - 8
The product of ‘a number’ and 3 could be written as 3 x a or 3a
Eight less than 3a means 3a minus 8 or 3a - 8
Answer:
a) The probability that exactly 17 of them enroll in college is 0.116.
b) The probability that more than 14 enroll in college is 0.995.
c) The probability that fewer than 11 enroll in college is 0.001.
d) It would be be unusual if more than 24 of them enroll in college since the probability is 0.009.
Step-by-step explanation:
We can model this with a binomial distribution, with n=29 and p=0.65.
The probability that k students from the sample who graduated from high school in 2012 enrolled in college is:

a) The probability that exactly 17 of them enroll in college is:

b) The probability that more than 14 of them enroll in college is:

c) Using the probabilities calculated in the point b, we have:

d) The probabilities that more than 24 enroll in college is:

The two parallel lines are FL and GK, on the right side of the shape. The other line is perpendicular to them.
The answer is C. 864, 5184, 31104
