Answer:
The guaranteed mileage should be 31800 miles.
Step-by-step explanation:
Consider the provided information.
It is given that the normally distributed with a mean of 40,000 miles and a standard deviation of 4,000 miles. Also the company desires that no more than 2 percent of the tires will fail to meet the guaranteed mileage.
That means the p < 0.02
Now with the help of the table the respective Z-score value of p < 0.02 is -2.05
From the provided information mean and standard deviation is given as
Now use the formula:
Substitute the respective values in the above formula.
Hence, the guaranteed mileage should be 31800 miles.
Given:
The vertices of a polygon QRST are T(-2, 3), Q(1, 5), R(3, -1) and S(0, 0).
To find:
The vertices for .
Solution:
The rule represents refection of polygon QRST across the x-axis.
If a figure is reflected across the x-axis, then
Using this rule, we get
Therefore, the vertices for are T'(-2, -3), Q'(1, -5), R'(3, 1) and S'(0, 0).
