The average life of an automobile tire of a certain manufacturer follows a Normal distribution, with a mean of 32,000 miles and a standard deviation of 1,250. Use the z-table to answer the question.

What tire life span separates the upper 30% of the life spans from the lower 70% of the life spans?

31,344 miles

32,650 miles

32,875 miles

33,250 miles

(B) 32,650 miles

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
