Find the distance between the two points. (1, 2), (7, 6)

zubka84 [21]

$\text {Distance = } \sqrt{(Y_2-Y_1)^2+(X_2-X_1)^2}$

$\text {Distance = } \sqrt{(6-2)^2+(7-1)^2}$

$\text {Distance = } \sqrt{(4)^2+(6)^2}$

$\text {Distance = } \sqrt{52}$

$\text {Distance = } 2\sqrt{13} \ \text { (radical form) or } 7.21 \ \text { (nearest hundredth)}$

The researcher is interested to know if policy A (new) is more effective than policy B (old). Frame the hypothesis and describe

vesna_86 [32]

Answer:

Null hypothesis: Policy B remains more effective than policy A.

Alternate hypothesis: Policy A is more effective than policy B.

Step-by-step explanation:

Remember, a hypothesis is a usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.

We have two types of hypothesis errors:

1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.

That is, rejecting the assumption that policy B remains more effective than policy A when it is actually true.

2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is actually false.

Are the equations m+ 3 = -5 and m = -2 equivalent? Explain.

Agata [3.3K]

*Answer:*

no.

*step-by-step solution:*

m + 3 = -5 || m = -2

*plug in -2 into m in the equation.*

-2 + 3 ≠ -5 || -2 + 3 = 1 <— THIS IS THE CORRECT ANSWER.
