Graph B.
Because y< so shade underneath the line
And because it is less then not less than or equal to then the line is dashed.

Answer:

(B)

Step-by-step explanation:

The given equation is $y< \frac{-2}{5}x+1$

Taking different values for x and y, we have the graph. Since y is less than $\frac{-2}{5} x+1$ , therefore the line plotted will be dotted because it is not having equality sign. If y would be less than or equal to $\frac{-2}{5}x+1$ , then the line will be the solid one.

1252 divided by 48 equals 26 r 4

Ksenya-84 [330]

I assume that in this question, you are asked to evaluate the value(s) of r. To answer that question, dividing 1252 by 48 gives us 26.0833 or 26. Mathematically expressing the solution,
26 = 26r^4
Then, divide the equation by 26, giving us 1 = r^4. Evaluate r. This will give us answers of +-1.

Answer:

b. Do not reject H0. We do not have convincing evidence that the mean weekly time spent using the Internet by Canadians is greater than 12.7 hours.

Step-by-step explanation:

Given that in a study of computer use, 1000 randomly selected Canadian Internet users were asked how much time they spend using the Internet in a typical week. The mean of the sample observations was 12.9 hours.

$H_0: \bar x =12.7\\H_a: \bar x >12,7$

(Right tailed test at 5% level)

Mean difference = 0.2

Std error = $\frac{6}{\sqrt{1000} } \\=0.1897$

Z statistic = 1.0540

p value = 0.145941

since p >alpha we do not reject H0.

b. Do not reject H0. We do not have convincing evidence that the mean weekly time spent using the Internet by Canadians is greater than 12.7 hours.
