Answer: 11.63%
Step-by-step explanation:
Given : The average time taken for your Internet service provider to remotely resolve a trouble ticket has a Normal distribution with a mean of 4.3 hours and a standard deviation of 4.3 hours.
i.e. 
and 
Let x denotes the time taken for your Internet service provider to remotely resolve a trouble ticket ( in hours).
The probability time can you expect to wait longer than a full (8-hour) business day for a resolution :
![P(x>8)=1-P(\leq8)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{8-4.3}{3.1})\\\\=1-P(z\leq1.1935)\ \ [\because\ z=\dfrac{x-\mu}{\sigma}]\\\\ =1-0.8837\ \ [\text{By z-table}]\\\\=0.1163=11.63\%](https://tex.z-dn.net/?f=P%28x%3E8%29%3D1-P%28%5Cleq8%29%5C%5C%5C%5C%3D1-P%28%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5Cleq%5Cdfrac%7B8-4.3%7D%7B3.1%7D%29%5C%5C%5C%5C%3D1-P%28z%5Cleq1.1935%29%5C%20%5C%20%5B%5Cbecause%5C%20z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5D%5C%5C%5C%5C%20%3D1-0.8837%5C%20%5C%20%5B%5Ctext%7BBy%20z-table%7D%5D%5C%5C%5C%5C%3D0.1163%3D11.63%5C%25)
Therefore , the percent of the time can you expect to wait longer than a full (8-hour) business day for a resolution = 11.63%
I have no clue how to do that if u do no how to do other math can u help me I need alot of help
Answer:
7/12
Step-by-step explanation
We have both of the values of the dozen of doughnuts 5/6 of a dozen blueberry and 1/4 dozen pumpkin. In order to determine how many more blueberry muffins Min has, we have to set the denominators to be the same number. To do this we need a common denominator. The least common denominator between 6 and 4 is 12. We multiply the top and bottom of the fraction 5/6 by 2 to get 10/12. We then multiply 1/4 by 3 to get 3/12. 10-3 = 7, therefore Min has 7/12 more blueberry muffins
Answer: Each person will get 3 candy bars
Step-by-step explanation:
The equation would be 26/7. Then, 7 goes into 26 three times with a remainder of 5.
x² + 2x + 2
Step-by-step explanation:
(F + G)(x)
= F(x) + G(x)
= 2x + x² + 2
= x² + 2x + 2
