Answer: A) and B)

Step-by-step explanation:

So for the first one, a closed circle means that it includes the point and the graph proceeds in the positive direction. So it will be whatever number it starts on in the x axis is less than or equal to x.

The second one you find the distance it moves each second.

You do this by distance over time d/t. Then you divide the 408 by that number.

So 264cm / 11 seconds = 24 cm/sec

Then 408cm/ 24cm per sec = 17s

Pick any value in the y column of the table. I'm going to pick 81. Divide the value you picked by the previous y value, which in my case would be 9

Dividing the values gives: 81/9 = 9

So the base is 9. We multiply each y value by 9 to get the next y value
Eg: to go from 1/81 to 1/9, we multiply by 9. Same for 1/9 to 1, and so on.

Answer: Choice B) 9

Note: This trick only works because x is increasing by 1 each time

EleoNora [17]

Answer:

Step-by-step explanation:

Given that a professor sets a standard examination at the end of each semester for all sections of a course. The variance of the scores on this test is typically very close to 300.

$H_0: s^2 = 300\\H_a: s^2 \neq 300$

(Two tailed test for variance )

Sample variance =480

We can use chi square test for testing of hypothesis

Test statistic = $\frac{(n-1)s^2}{\sigma^2} \\=62.4$

p value = 0.0100

Since p <0.05 our significance level, we reject H0.

The sample variance cannot be claimed as equal to 300.
