Answer:
30 miles
Step-by-step explanation:
2.5 h
12 miles per hour
12x2.5=30
The anwser of your question is 36 sq.ft.
a) For x = 27:
z = 27-28/2 = -0.5
For x = 31:
z = 31-38/2 = 1.5
From the normal distribution table, P(27 < x < 31) = P(-0.5 < z < 1.5) = P(z < 1.5) - P(z < -0.5) = 0.9332 - 0.3085 = 62.47%
b) For x > 30.2:
z = 30.2-28/2 = 1.1
From the normal distribution table, P(x > 30.2) = P(z > 1.1) = 1 - P(z > 1.1) = 1 - 0.8643 = 13.57%
Dose not make sense because I don't get what you mean when you say there their for classes I think it should be there are and you didn't tell use how much classe there are
