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 $\mu = 40,000\ \text{and}\ \sigma = 4000$

Now use the formula: $z=\frac{x-\mu}{\sigma}$

Substitute the respective values in the above formula.

$-2.05=\frac{x-40000}{4000}$

$-8200=x-40000$

$-8200+40000=x$

$31800=x$

Hence, the guaranteed mileage should be 31800 miles.

In slope-intercept form, what is the equation of the line passing through the points (2, 13) and (5, 22)

KiRa [710]

(2,13),(5,22)
slope = (22 - 13) / (5 - 2) = 9/3 = 3

y = mx + b
slope(m) = 3
use either of ur points...(2,13)...x = 2 and y = 13
now sub and find b, the y int
13 = 3(2) + b
13 = 6 + b
13 - 6 = b
7 = b
so ur equation is : y = 3x + 7 <===
