A professor gives a multiple choice exam where each question has five choices. The professor decides not to count a question against students if the class as a whole does significantly worse on the question than they would have done simply by guessing. In other words, the teacher tests H_0: p=0.20H 0 :p=0.20H, start subscript, 0, end subscript, colon, p, equals, 0, point, 20 versus H_\text{a}: p<0.20H a :p<0.20H, start subscript, start text, a, end text, end subscript, colon, p, is less than, 0, point, 20 for each question, where ppp is the proportion of students who would correctly answer the question.

i believe that is true.

step-by-step explanation:

hope my answer has you if not i'm sorry.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

.

step-by-step explanation:

.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
