Step-by-step explanation:
you divide 2.28 by 9.5 for the first answer then multiply that answer by 5.5
Answer:

Step-by-step explanation:
We want the probability that the 35 cars are loaded onto the ferry. Therefore:
Since
μ=1.8 and σ=0.5 we have:
P(X<35 )=P ( X−μ<35−1.8 )=P((X−μ)/σ<(35−1.8)/0.5)
Since
(x−μ)/σ=Z and

we have:

Use the standard normal table to conclude that:

11 units is the correct answer to this question.
88 + 89 + 79 + 77 = 333. 420-333= 87. The minimum score he can get is 87
