Apizza shop advertises that they deliver in 30 minutes or less or it is free. people who live in homes that are located on the opposite side of town believe it will take the pizza shop longer than 30 minutes to make and deliver the pizza. write the null and alternative hypotheses that can be used to conduct a significance test. a. h0: m ≤ 30, ha: m > 30 b. h0: m > 30, ha: m < 30 c. h0: m < 30, ha: m > 30 d. h0: m ≥ 30, ha: m < 30

The correct option is a) : m ≤ 30, : m > 30

Step-by-step explanation:

Consider the provided information.

A pizza shop advertises that they deliver in 30 minutes or less or it is free.

People who live in homes that are located on the opposite side of town believe it will take the pizza shop longer than 30 minutes to make and deliver the pizza.

: Pizza shop makes and delivers the pizza ≤ 30 minutes.

: Pizza shop makes and delivers the pizza m > 30 minutes.

Hence, the correct option is a) : m ≤ 30, : m > 30

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
