Answer:

A. ASA Congruence Postulate

Step-by-step explanation:

We have marked that ∠BAE and ∠CDE are congruent. We also have marked that AE and ED are congruent.

∠AEB and ∠CED are also congruent; this is because they are vertical angles. Vertical angles are opposite angles that share only a vertex; these are vertical angles and thus are congruent.

This gives us two angles and an included side; this gives us ASA.

I am a part of a whole I am greater than 3/4 but less than 9/10. I am a decimal with 3 in the hundredths place. What number am I

Alborosie

Answer:

"You" are 0.83.

(Alternative fraction version: 83/100)

Step-by-step explanation:

First, let's turn 3/4 and 9/10 into decimals.

3/4 becomes 0.75, and 9/10 becomes 0.9.

We know that it has to be a decimal, and we also know it must be greater than 0.75 but less that 0.9.

It can't be 0.73, since that's less than 0.75. It also can't be 0.93, since that's over 0.9. That means we're left with 0.83.

Our final answer is 0.83, AKA 83/100.

The impact on sampling of increasing the sample size is: There is no specific relationship between sample size and sampling erro

m_a_m_a [10]

Using margin of error, it is found that increasing the sample size results in a smaller sampling error.

The equation for the <em>margin of error</em> is given by:

$M = c\frac{s}{\sqrt{n}}$

In which:

c is the critical value according to the distribution used.

s is the standard deviation, either of the sample or of the population.

n is the sample size.

From the equation, it can be noted that the margin of error is inversely proportional to the square root of the sample size, hence, increasing the sample size results in a smaller sampling error.

Can I PLEASE get some help?

V125BC [204]

The 1st and 3rd choices are irrational. The other 2 are rational. Irrational numbers are numbers that you can't make a simple fraction out of.
