  • Consume per min=40
  • Popcorns be x

Equation of expression

\\ \tt\hookrightarrow y=40x+682

Compare to y=mx+b

  • Slope=m=40
  • Y intercept=b=682

Slope intercept form: y = mx + b

Equation: 682 = 40x
Slope = 40 (or 40/1)
Y-intercept = 0

In this case,

y = the total
x = the amount of minutes
y-intercept = 0, since there isn’t a b in the equation.
slope = 40, because y = mx + b is 682 = 40x

This should be correct, unless there is missing information in the question.

Answer:

Since the calculated value of z= -1.496 does not fall in the critical region z < -1.645 we conclude that the new program is effective. We fail to reject the null hypothesis .

Step-by-step explanation:

The sample proportion is p2= 7/27= 0.259

and q2= 0.74

The sample size = n= 27

The population proportion = p1= 0.4

q1= 0.6

We formulate the null and alternate hypotheses that the new program is effective

H0: p2> p1   vs  Ha: p2 ≤ p1

The test statistic is

z= p2- p1/√ p1q1/n

z= 0.259-0.4/ √0.4*0.6/27

z=  -0.141/0.09428

z= -1.496

The significance level ∝ is 0.05

The critical region for one tailed test is z ≤ ± 1.645

Since the calculated value of z= -1.496 does not fall in the critical region z < -1.645 we conclude that the new program is effective. We fail to reject the null hypothesis .

Determine the slope of each line.
faust18 [17]
(2,-2)(5,7)

7-(-2)= 9
5-2= 3
9/3= 3

slope = 3

(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
