With 10 to the power to a negative number, it's easier.
Here's a trick: The negative number is the places to the right of the decimal. The last number is a 1, while the rest are 0s.

From this, we get: $10^{-4}=\boxed{0.0001}$

10^4 = 10000 (four zeros at the end)
10^-4 = 0.0001 (four zeros at the front)

Please Answer If each quadrilateral below is a rectangle, find the missing measures

denpristay [2]

To solve for YW and VX I would use the Pythagorean Theorem. Add 19^2 to 31^2. Your answer should come out to be 1322. Now, find the square root of 1322. Due to the fact that it is not a perfect square, I would round this number. I am not sure if you were given a decimal place to round to, so I will just give you the full number (36.35932) Also, both diagonals are congruent, so ZX would just be half of 36.35932. Again, round the where you are asked to round.

Researchers study the relationship between interpersonal violence and health in college age women. The selected an alpha of 0.05

Lina20 [59]

Answer:

Explained below.

Step-by-step explanation:

A statistical hypothesis test is being performed to determine whether there was a significant difference in the type of primary residence (home vs. student housing) for abused versus non abused college aged women.

The hypothesis can be defined as:

H₀: There is no difference in the type of primary residence or abused versus non abused college aged women.

Hₐ: There is a significant difference in the type of primary residence or abused versus non abused college aged women.

The significance level of the test is:

α = 0.05

The computed p-value is:

p-value = 0.35

p-value = 0.35 > α = 0.05

The null hypothesis will not be rejected.

The p-value is inversely related to the sample size of the test.

That is, larger the sample size smaller is the p-value and smaller the sample size larger is the p-value.

A p-value of 0.35 is very large and unusual. This can happen because of the inadequate sample size selected.

As the p-value indicates an unusual result, it can be said that an error has been made while concluding that the null hypothesis is true, when in fact it is not.

This type of error is known as the type II error.

The correct decision should be:

There is a statistically significant difference in the type of primary residence for abused vs. non-abused college aged women.
