A teacher wants to see if a new unit on taking square roots is helping students learn. She has five randomly selected students t
Dima020 [189]

Answer:

The P-value for this test is P=0.00006.

Step-by-step explanation:

We have a matched-pair test, with a test statistic t=-14.9.

The degrees of freedom in a sample of 5 students is:

df=n-1=5-1=4

For a  t=-14.9 and 4 degrees of freedom, a left-tail test will have a P-value of:

P-value=P(t_4

The claim is that the new unit on taking square roots is helping students to learn. This test concludes that there is statistical evidence to support the claim that the new unit is helping students to learn.

Find the equation of the linear function represented by the table below in slope-
Anarel [89]

Answer:

y = 3x + 5

Step-by-step explanation:

slope:

11 - (-1) / 2 - (-2) = 12/4 = 3

slope intercept form is y = mx + b, so right now you have m = 3:

y = 3x + b

now, since you know x = -2 and y =-1 is a solution, you can plug those values in:

-1 = 3 * -2 + b

-1 = -6 + b

5 = b

This means the equation is y = 3x + 5

Answer:

A. (x-5)(x-7)

B. It means the zeroes of the graph are at (5,0) and (7,0)

Step-by-step explanation:

A

find what + what equals -12, and multiples to 35.

List all multiples of 35.

1 35

<em>5 7</em>

- 12 is negative so that means it is -5 and -7

(x-5)(x-7)

B

The factor numbers are where the zeroes on a graph are, <u>but</u> whatever is in parenthesis, the number is opposite on a graph (e.g. if it was (x-3), the zero would be (3,0)
