Answer:
c
Step-by-step explanation:
we have to use a mean to describe the center
Answer
given,
thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.
X = U[0.95,1.05] 0.95≤ x ≤ 1.05
the cumulative distribution function of flange
F(x) = P{X≤ x}=
=
b) P(X>1.02)= 1 - P(X≤1.02)
= 
= 0.3
c) The thickness greater than 0.96 exceeded by 90% of the flanges.
d) mean = 
= 1
variance = 
= 0.000833
2t+2d+2c=30
2(8.50)+2(3.50)+2(3.00)=$30
t representing tickets d representing drinks c representing candy
the answer really depends on how much of each item they buy
if they bought more than 2 of each just change the 2 to the number of items bought
The answer is positive 25 and negative 25
