Answer:
There are no "following values" in the problem.
Step-by-step explanation:
ƒ(x) = -2x + 3
For any value of X, enter that number in the equation and calculate f(x) [y].
For example, if x is 2:
ƒ(x) = -2x + 3
ƒ(2) = -2(2) + 3
y = -2(2) + 3
y = -4+3
y = -1
The ordered pair for when x=2 would be (2,-1)
Answer:

Step-by-step explanation:
The average is:

The standard deviation is:

We want the probability that a tire lasts more than 39,000 miles.
This is:

Now we must transform these values to those of a standard normal distribution to facilitate calculation by using the probability tables.

This is:
---------- (For the symmetry of the standard normal distribution)
When you search for the normal standard table, you get the following value:
