The function would be:
6.95 + (0.75*t) = p
The pictures too blurred, can you write it out?
I don’t understand what the question is telling me
The probability that a randomly selected customer takes more than 10 minutes will be 8.38%
<em><u>Explanation</u></em>
The average or mean
is 8.56 minutes and standard deviation
is 1.04 minutes.
<u>Formula for finding the z-score</u> is: 
So, the z-score for
10 minutes will be.....

Now, according to the standard normal distribution table,
. So.....

So, the probability that a randomly selected customer takes more than 10 minutes will be 8.38%
Answer:
A triangle is a total of 180 degrees
So to find what x equals we are going to add up all the degree measurements and make them equal to 180
3x+2x+20+4x-20=180 (combine any like terms on the left)
3x+2x+4x+20-20=180 (3x+2x+4x=9x, 20-20=0)
9x=180 (divide both sides by 9)
x=20
Hope this helps ;)
