Amanufacturer produces crankshafts for an automobile engine. the crankshafts wear (inches) is of interest because it is likely to have an impact on warranty claims. a random sample of 15 shafts is tested and the sample mean wear is computed to be 2.78 inches. it is known that the population standard deviation is equal to 0.90 inches and that wear is normally distributed. if you were to do a hypothesis test using the data from this problem to determine if the population mean wear is not equal to 3 inches, which test statistic would you need to use?

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)

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph

step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9
