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.
You write y=mx+b
m= slope
x=variable
b= y-intercept
A resposta é oito. :))))))
The linear parent function is y = x
it has a slope equal to 1 and passes through the origin. All the other linear functions are derived from this parent function.
So, the correct answer to this question is option B
