Answer:
a) 0.8836
b) 0.7339
c) 0.2342
Step-by-step explanation:
Books classified as fiction = 94% or 0.94 probability
Books classified as non-fiction = 1 - 0.94 = 0.06
a) for two books, we get: 0.94 * 0.94 = 0.8836 Probability
b) The probability that all five books are fiction is: 0.94^5
This equals 0.7339 Probability
c) Probability that one books is non-fiction, while the other 4 are fiction is determined in the following way:
Probability of non-fiction * probability of fiction^(number of books)
0.06 * 0.94^4 = 0.0468
This does not account for the order at which the non-fiction book shows up. Such as the non-fiction book being the first book picked, or in another case - the non-fiction book being the last picked.
Since there are 5 ways this could occur, the total probability will be calculated as shown: 0.0468 * 5 = 0.2342 Probability
Answer:
see below
Step-by-step explanation:
4a) x / 12 = 5
multiply both sides of equality by 12
x = 60
4b) Dan charges $12 per hour, this doesn't change so it's the constant of proportionality.
4c) S = 12h
If you substitute the h with the number of hours worked multiply with the constant of proportionality 12 you'll get the amount charge S.
5) Equation for a slope is (y₂ - y₁) / (x₂ - x₁):
(2 - 0) / (6 - 1)
= 2/5
