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.
The correct answer is $3.18 per gallon
Answer:
1,A 2:C
Step-by-step explanation:
Answer:
It’s B
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
The figure inside the circle is symmetric. Therefore, 3x + 5 = 5x - 7. Solving for x, we subtract 3x from both sides and then add 7 to both sides. This comes out to 2x = 12, meaning that x must be 6.
