Answer:
Step-by-step explanation:
x, height of men is N(69, 2.8)
Sample size n =150
Hence sample std dev = 
Hence Z score = 
A) Prob that a random man from 150 can fit without bending
= P(X<78) = P(Z<3.214)=1.0000
B) n =75
Sample std dev = 
P(X bar <72) = P(Z<9.28) = 1.00
C) Prob of B is more relevent because average male passengers would be more relevant than a single person
(D) The probability from part (b) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height.

Answer:
the is option d cause big number is divided by small ones.
Step-by-step explanation:
hope it's right
15 meals x $0.80 = $12.
$18 - $12 = $6.
If one movie ticket is $3 then she must have purchased 2 with $6.
Part A - 15x0.8=18-x=x
Part B-
15 x 0.8 = 12
18- 12=6
Part C- 2
Answer:
Step-by-step explanation:
Given
Required
Determine a homogeneous linear differential equation
Rewrite the expression as:
Where
and 
For a homogeneous linear differential equation, the repeated value m is given as:
Substitute values for 
and 
Add 1 to both sides
Square both sides
In complex numbers:
So, the expression becomes:
Add 1 to both sides
This corresponds to the homogeneous linear differential equation
