Answer:
1.1572971e+42
Step-by-step explanation:
We will check if the elevator can hold 10 man
X~(177,32^2)
n= 10
P(SigmaX>172)
SigmaX~(177*10,(32^2)*10)
SigamX~N(1770, 101.19^2)
P(SigmaX>172*10=1720) =Z=(1720-1770)/101.19
Z = -0.49
From Z table Z=-0.49
P(Z=-0.49) = 0.3121 (probability they will not overload)
1- 0.3123 = 0.6879 = 68.79%
The elevator is not safe, the probability to be more the 172 is 68.79%, high probability they could not make it.
Answer:

Step-by-step explanation:
Hope this helps. I switch the x and y so its easier to solve.
Answer:
From general equation of a line:
m » slope, b » y-intercept.
but perpendicularly:
at point (6, 2):
therefore, equation is :
