Answer: 0.60
Step-by-step explanation:
Given: Mean : 
Standard deviation : 
The formula to calculate z is given by :-
For x= 20 minutes
The P Value =
Hence, the probability that a randomly selected shopper will spend less than 20 minutes in the store= 0.60
Answer:145,003 59
Step-by-step explanation:
he population 2016, this is more precise, will be 145116 people. If you just rounded the value of X to population growth rate to 1.176, then the population Uh in 2016 is 145,003 59.
To find x:
tan ° = opposite / adjacent
you should get, 6.008…
To find y:
cos ° = adajcent / hypotenuese
you should get, 11.666..
[I'll let you try how to find it with the clues given]
Volume of a cone: (1/3)πr²h
Data:
V=31.5 in³,
r=3 in
Then:
V=(1/3)πr²h
31.5 in³=(1/3)π(3 in)²h
<span>(1/3)π(3 in)²h=31.5 in</span>³
(1/3)π(9 in²)h=31.5 in³
3πin² h=31.5 in³
h=(31.5 in³) / (3π in²)
h≈3.34 in
answer: the height of the cone is 3.34 in.
