Answer:
3972.72 specimens
Step-by-step explanation:
We solve using the z score formula:
z = (x-μ)/σ where
x is the raw score = 73 cm
μ is the population mean = 147 cm
σ is the population standard deviation = 30 cm
N is the number of samples = 4000
For x > 73
z = 73 - 147/30
z = -2.46667
Probability value from Z-Table:
P(x<73) = 0.0068189
P(x>73) = 1 - P(x<73) = 0.99318
The probability of having a height greater than 73cm is: 0.99318
The number of specimens that have a height greater than 73cm is calculated as: 0.99318 × 4000
= 3972.72 specimens

Answer:
There are 4 Phones in the Family phone Plan.
Step-by-step explanation:
Given:
Monthly payment for each phone = 
Let the number of phones in the plan be x
cost of the family data plan per month = 
Total Monthly bill = 
Total Monthly bill = Monthly payment for each phone 
number of phones in the plan 
cost of the family data plan per month
∴ The equation becomes after substituting the value,
∴There are 4 Phones in the Family phone Plan
I just graphed all 4 and didn’t see where any are on the same horizontal line. I might be missing something.
Your answer is 2. Simply do -12.2- -14.2 and you will get 2.
