Answer:
7, 9, 17
Step-by-step explanation:
The sum of the two smallest numbers has to form a number larger that the largest number, and 7 + 9 = 16 which is less than 17.
10 boxes of paper at 6 lbs each = (10 * 6) = 60 lbs
36 boxes of pens at 12 oz each = (36 * 12) = 432 oz.
there are 16 oz in 1 lb....so 432 oz = (432/16) = 27 lbs.
so we have a total weight of (60 + 27) = 87 lbs
shipping charges : $ 12 for first 20 lbs, $ 10 for the next 30 lbs....so thats 50 lbs...leaving 37 lbs at 0.50 per lb = 37(0.50) = $ 18.50
for a total of : 12 + 10 + 18.50 = $ 40.50 <==

The number of employees is 91.
According to the statement
Given that the standard deviation = 24.5
The width in the question = 13
We solve for the margin of error E.
E = width / 2
E= 13/2 = 6.5
At 90%
Alpha = 1-0.90
= 0.1
Alpha/2 = 0.1/2 = 0.05
Z 0.05 = 1.576
Now find the Sample size n
= ((1.576x24.5)/2)²
= 90.8
= 91
So, The number of employees is 91.
