Answer:
Probability of getting at least 9 out of 18 correctly is 0.0043
Step-by-step explanation:
We have
n = 18
p = 1/5 for correct answer
q = 4/5 for wrong answer
P( 9 
X 18) = 1 - P(0 X 8)
= 1 - 0.9957
=0.0043
Say she chooses topic A. She needs at least one book to arrive on time. The probability that no books arrive on time is 0.1 x 0.1 = 0.01 so the probability that at least one book arrives on time is 1 - 0.01 = 0.99.
Say she chooses topic B. She needs at least two books to arrive on time. The probability of no books arriving on time is 0.1 x 0.1 x 0.1 x 0.1 = 0.0001. The probability of exactly one book arriving on time is 4 x 0.1 x 0.1 x 0.1 x 0.9 = 0.0036 (binomial probability distribution formula - the 4 comes from 4C1). So the probability of her not getting enough books is 0.0001 + 0.0036 = 0.0037 and the probability she does get the books she needs on time is 1 - 0.0037 = 0.9963.
So she should choose topic B.
Answer:
He worked 40 regular hours.
He 4 hours beyond 40.
He worked 40 + 4(1.5) = 40 + 6 = 46 adjusted hours
Step-by-step explanation:
John worked 44 hours and a regular work week is 40 hours. This means John worked 40 regular hours plus 4 hours over time. He receives time and a half or 1.5 for each hour over 40.
So 40 + 4(1.5) = 40+6=46 adjusted hours.
This is the General quadratic equation
