Answer:
0.9007 is the probability that a student scored below 86 on this exam.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 77
Standard Deviation, σ = 7
We are given that the distribution of examination grades is a bell shaped distribution that is a normal distribution.
Formula:

a) P(student scored below 86)
P(x < 86)
Calculation the value from standard normal z table, we have,

0.9007 is the probability that a student scored below 86 on this exam.
0.77(13.50×40)= 415.8
The answer is $415.8
Hope this helps :)
The Pizza maker can make 1.5 pizzas in 1 minute.
Slope of 2y = x + 5:-
This is y = 0.5 x + 2.5 in slope intercept form so its slope = 0.5
Slope of the line perpendicular to it = -1 / 0.5 = -2
it passes through (2 , 1) so we have
y- 1 = -2(x - 2)
y = -2x + 4 + 1
The answer is y = -2x + 5
