<h3>Answer: D) 4</h3>

===========================================================

Explanation:

The width of the confidence interval is 20-12 = 8 units. That cuts in half to get 8/2 = 4 which is the margin of error.

The center of the confidence interval is (12+20)/2 = 32/2 = 16. Add four onto this to get 16+4 = 20, which is the right endpoint. Subtract four from the center to get 16-4 = 12, which is the left endpoint.

Effectively, it's like saying "an archer aims for the value 16 on the number line, and the arrow could land as high as 20 or as low as 12".

ki77a [65]

Answer: she would receive 39,000 and that is 60% of her incomeExplanation: Now as you can she is making 65,000 per year. So you multiply 65,000 with 60/100. You make 60% into 60/100 because it's a percent and a decimal. Like I was saying if you multiply 65,000 with 60/100 you will get 39,000 which is 60% of her tax income

Nancy has not used the most effective word in sentence 4. Which word should replace have to create a more effective sentence?.

katrin [286]

The best word to replace "have" is the word "manage".

<h3>What is an effective word?</h3>

A word is considered effective/ineffective depending on whether the word transmits the author's message. In the case of Nancy, she wants to show students struggle as they deal with classes, homework, and extracurricular activities.

<h3>How to replace the word "have"?</h3>

The word "have" is ineffective because it does not completely show how difficult the situation is for students. One word that can show this struggle is "manage" because this emphasizes Nancy's point of view.

Note: This question is incomplete because the text and options are missing; here are the missing sections:

Select the correct answer. what is the value of this limit? a. b. c. d. e.

dlinn [17]

The value of the limit expression $\lim_{x \to 3} \sqrt{x^2 + 7} + 5$ is 9, and it means that the function approaches 9, as x approaches 3.

<h3>How to evaluate the limit?</h3>

The limit expression is given as:

$\lim_{x \to 3} \sqrt{x^2 + 7} + 5$

This means that we determine the value of the function as x approaches 3.

So, we have:

Limit = √(3^2 + 7) + 5

Evaluate the square

Limit = √(9 + 7) + 5

Evaluate the sum

Limit = √16 + 5

Evaluate the square root

Limit = 4 + 5

Evaluate the sum

Limit = 9

Hence, the value of the limit $\lim_{x \to 3} \sqrt{x^2 + 7} + 5$ is 9
