Answer:
99.8% is the percent of bags contain between 62 and 86 potato chips.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 74
Standard Deviation, σ = 4
We are given that the distribution of number of potato chips in a bag is a bell shaped distribution that is a normal distribution.
Formula:

P( bags contain between 62 and 86 potato chips)

The answer to the question
Answer: x = 11
Step-by-step explanation:
Complementary angles = 90*
Set the two equations equal to 90. Solve
4x + 6 + 4x - 4 = 90
8x +2 = 90
8x = 88
x = 11
Plug it in to see if it makes equation true
4 (11) + 6 + 4 (11) - 4 = 90
44 + 6 + 44 - 4 = 90
50 + 40 = 90
90 = 90
Answer: C. 4 friends will borrow 4 books each, 1 friend will borrow 3 books
Step-by-step explanation:
Friend 1 has 4 books
Friend 2 has 4 books
Friend 3 has 4 books
Friend 4 has 4 books
So far, that’s a total of 16 books.
Now add the 3 books of the 5th friend to that:
16 + 3 = 19
This is the way in which a group of friends can most evenly divide the 19 books.

Answer:
Step-by-step explanation:
Direct proportion
60: 1 5 /12 = 120 : x
60: 17/12 = 120:x
Product of extremes = product of mean
60*x = (17/2)*120
