Answer:
Step-by-step explanation:
Z-score:
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
You listen to the radio station for 1 hour, at a randomly selected time, and carefully observe that the amount of advertising time is equal to 17 minutes. Calculate the z-score for this amount of advertising time.
We have to find Z when X = 17. So
Answer:
I think the answer is 25
Step-by-step explanation:
So, if you add 2 and 3, you get 5.
Multiply 5 by 10 to get 50
Divide 50 by 2 to get 25
So, you'll need 25 gallons of paint.

Answer:
3 hours 40 minutes.
Step-by-step explanation:
We are told that we have 1320 garments and it takes an employee 20 seconds to tag a garment.
1 employee tags one garment in 20 seconds.
So garments tagged by 1 employees in 1 minute will be 
garments.
2 employees will tag 3*2=6 garments in 1 minute.
To find the total time it will take two employees to tag all the garments we will divide total number of garments by 6.
Therefore, it will take 220 minutes or 3 hours and 40 minutes for 2 employees to tag 1320 garments.
The answer is $50
Assume the original cost price to be $x
Therefore ,
X - 36X/100 = $32
-> 100x - 36x = 32 x 100
-> 64x = 3200
-> x = 3200/64
-> x = 50
