Answer:
The test statistic for this hypothesis test for a proportion is z=1.90.
Step-by-step explanation:
This is a hypothesis test for a proportion.
The claim is that the unemployment rate is less than 5%.
Then, the null and alternative hypothesis are:

The sample has a size n=1500.
The sample proportion is p=0.061.

The standard error of the proportion is:
Then, we can calculate the z-statistic as:

Answer:
The answer is C, use a calculator and you'll get the answer.
The proofing of the triangle is illustrated below.
<h3>How to illustrate the triangle?</h3>
Based on the information, the reflexive property of equality states that an angle or shape is always congruent to itself.
The alternate interior angle theorem is that when two parallel lines are cut by a transversal, then the alternate interior angles are the same.

It’s 4 because it’s in front of X
Answer:
The number is 8.
Step-by-step explanation:
Rewrite the word problem as an equation.
The sum of (we will be adding.), half of a number (we can use x, this will be written as x/2.) and double the number (this will be written as 2x) is 20.
To find the number, solve the equation.
x/2 + 2x = 20
Multiply both sides by 2.
x + 4x = 40
Combine terms.
5x = 40
Divide both sides.
x = 8.
