57.5 is the answer. Because think of 200 as 100% and 15 out of a hundered is ______. Right.
Approximately 95% of bags contain between 65 and 85 potato chips.
<u>Step-by-step explanation</u>:
step 1 :
Given,
The mean, M = 75
Standard deviation, SD = 5
step 2 :
From Normal distribution,
The left side of mean is 32% = M-SD, 16% = M-2SD and 2% = M-3SD
The right side of mean is 32% = M+SD, 16% = M+2SD and 2% = M+3SD
step 3 :
Calculate for left side: M-SD = 75-5 = 70 and M-2SD = 75-10 = 65
Calculate for right side: M+SD = 75+5 = 80 and M+2SD = 75+10 = 85
step 4 :
Calculate the percentage between 65 and 85:
(M-SD) + (M-2SD) + (M+SD) + (M+2SD) = 32% + 16% + 32% + 16%
= 96 % (which is approximately 95 %)

The number of hours it take to watch the series twice is 18.25 hours.
<h3>
Number of hours</h3>
First step is to calculate the time it takes to watch it twice
Time=2×3.285×10^4
Time=6.57×10^4 seconds
Second step is to convert the second into hour
1 hours=3600 second
Hence:
6.57/3600×10^4
18.25 hours
Inconclusion the number of hours it take to watch the series twice is 18.25 hours.
