The percentage of bags contain between 65 and 85 potato chips is 95%.
<u>Step-by-step explanation:</u>
A probability distribution that is symmetric and the data near the mean are more frequent than far is known as a normal distribution. Normal distributions are important in statistics and are often used to represent real-valued random variables.
The formula for finding the percentage of bags using normally distributed is given as
f(x) = (1 / sigma * square root 2 *pi) * e^((-1/2)*((x-u)/sigma))
Substituting the values of mean and standard deviation,
The percentage of bags contain between 65 and 85 potato chips is 95%.
Answer:
Expected revenue = $400
Step-by-step explanation:
Expected revenue is given by the formula;
Expected revenue = Sum of x * p(x)
x = 200
x = 600
p(x) = 1/2
p(x) = 1/2
Substituting, we have;
Expected revenue = 200*1/2 + 600*1/2
= 100 + 300
= $400
Therefore, expected revenue = $400
Let her salary before the rise = x pounds then
x + 0.02x = 39474
1.02x = 39474
x = 39474 / 1.02 = £38,700 answer
Answer:
Given
This is our initial premise.
2) Linear pairs of angles are supplementary
This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.

4) Substitution of 1. into 3.
As with 2), this may differ based on the teacher or book. Some may prefer that you write out the equation, whereas others may be satisfied with the references as given. Check for similar examples.

Answer:
24/25
Step-by-step explanation:
.96
the last digit is in the hundredths place so put it over 100
96/100
now we simplify
divide top and bottom by 4
