suppose 215 subjects are treated with a drug that is used to treat pain and 54 of them developed nausea. Use a 0.01 significance level to test claim that more then 20% of users develop nausea

answer:

24pi or letter c

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.

step-by-step explanation:

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
