Answer:

No

Step-by-step explanation:

If the lines are perpendicular then they will be the negative reciprocals of each other.

Calculate the slope using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)

$m_{PQ}$ = $\frac{-12+10}{-5+8}$ = - $\frac{2}{3}$

Repeat the process with

(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)

$m_{RS}$ = $\frac{-5+6}{17-9}$ = $\frac{1}{8}$

The slopes are not the negative reciprocal of each other, thus they are not perpendicular.

Which of the following is true?

VARVARA [1.3K]

Answer:

The correct option is c which is if this test was one-tailed instead of two-tailed, you would reject the null.

Step-by-step explanation:

a: This statement cannot be true as the p-value for a 1 tailed test is dependent on the level of significance and other features.

b: This statement cannot be true as there is no valid mathematical correlation between the p-value of the one-tailed test and the current p-value.

c: This statement is true because due to the enhanced level of significance, the null hypothesis will not be rejected.

d: This statement is inverse of statement c which cannot be true.

e: The statement cannot be true as there is no correlation between the current p-value and the p-value of 1 tailed test. The correlation exists between the values of one-tailed and two-tailed p-values.

Radical 6x^2 multiplied by radical 18x^2

Alina [70]

Does radical mean square root?, because radical can mean square root, cube root, fourth root, etc.

Well, I'm going to assume that radical = square root

So, if you have two square root functions, you can multiply the numbers within the square root, so you now have $\sqrt{48x^4}$ , which I'm not sure if you want it simplified or not
