Suppose a batch of steel rods produced at a steel plant have a mean length of 164 millimeters, and a variance of 121. If 287 rods are sampled at random from the batch, what is the probability that the mean length of the sample rods would be less than 164.56 millimeters? Round your answer to four decimal places.

900 degrees

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
