Answer:
He should word his statement as "Free replacement for tires that wear before 30875 miles."
Step-by-step explanation:
If he is willing to replace 10% of tires he should find the life of tires that gives an area of 10% in the normal distribution graph.
Now for 10% of area standard normal deviate Z can be obtained from normal distribution table
Using normal distribution table for 10% area we have Z = -1.28
Thus we have ![Z=\frac{X-\overline{X}}{\sigma }\\\\\therefore X=\sigma Z+\overline{X}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7BX-%5Coverline%7BX%7D%7D%7B%5Csigma%20%7D%5C%5C%5C%5C%5Ctherefore%20X%3D%5Csigma%20Z%2B%5Coverline%7BX%7D)
Applying given values we get
![X=-1.28\times 2500+34000\\\\X=30875miles](https://tex.z-dn.net/?f=X%3D-1.28%5Ctimes%202500%2B34000%5C%5C%5C%5CX%3D30875miles)
We can start by multiplying $19,200 by 12%. This is 2304. Subtract 19,200 from 2304 and you get 16,896. We could have also received this answer by multiplying by 88%. This would have given us 16,896. So we can use this equation: (((((19,200*88%)88%)88%)88%)88%)=$1011.08.
Hope this helped!
Answer:
the correct answer is d
Step-by-step explanation:
w(s)=weeks saved and 20s is the gain of 20 dollars every week. and the 95 is the starting amount that sam had
(a)
The unknown information is the amount of potting soil Emmanuel bought last week.
(b)
40 lb of potting soil is 4 lb more than 3 times p (the amount of potting soil he bought last week).
The equation:
![40=3p+4](https://tex.z-dn.net/?f=40%3D3p%2B4)
(c)
![40=3p+4 \ \ \ |\hbox{subtract 4} \\ 36=3p \ \ \ \ \ \ \ \ |\hbox{divide by 3} \\ p=12](https://tex.z-dn.net/?f=40%3D3p%2B4%20%5C%20%5C%20%5C%20%7C%5Chbox%7Bsubtract%204%7D%20%5C%5C%0A36%3D3p%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%20%7C%5Chbox%7Bdivide%20by%203%7D%20%5C%5C%0Ap%3D12)
The solution to the equation is 12.
(d)
Last week Emmanuel bought 12 lb of potting soil.
