Answer:

270 miles

Step-by-step explanation:

45 minutes = 67.5 miles

1 minute = 67.5 ÷ 45 = 1.5

3 hours = 60 x 3 = 180 minutes

180 minutes = 1.5 x 180 = 270

pashok25 [27]

Answer:

Step-by-step explanation:

Whenever p < alpha we reject our null hypothesis.  Otherwise we accept our null hypothesis.

Hence p should be high to accept null hypothesis

Option A is incorrect

B is correct

C is wrong as p is the probability

D False

Option B is right.

What is the equation of this line in slope-intercept form?
Sloan [31]

The correct answer is A) y = -3x - 1

In order to find this, start by using the two points on the line to find the slope.

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

m = (-4 - 2)/(1 - -1)

m = -6/2

m = -3

Since A is the only one with a -3 slope, this is the correct answer.
