Art [367]

Answer:

±12.323

Step-by-step explanation:

A study by the department of education of a certain state was trying to determine the mean SAT scores of the graduating high school seniors. The study examined the scores of a random sample of 238 graduating seniors and found the mean score to be 493 with a standard deviation of 97. Calculate the margin of error using the given formula. How could the results of the survey be made more accurate?

The formula for margin of Error =

±z × Standard deviation/√n

We are not given the confidence interval but let us assume the confidence interval = 95%

Hence:

z score for 95% confidence interval = 1.96

Standard deviation = 97

n = random number of samples = 238

Margin of Error = ± 1.96 × 97/√238

Margin of Error = ±12.323

A rectangle prism is 8 inches long and 5 inches wide. It is filled with water up to 2 inches below the top. The height of the wa
Tamiku [17]

The volume of the rectangular prism is 240 in³

<u>Explanation:</u>

Given:

Length of the prism, l = 8 in

Width of the prism, w = 5 in

Height of the prism, h = 2 + 4 in

                                 h = 6 in

Volume of the rectangular prism = length X width X height

V = 8 in X 5 in X 6 in

V = 240 in³

Therefore, the volume of the rectangular prism is 240 in³

What is the right answer. Thank you!!!! :) there is a picture also!
Archy [21]
To solve this problem, you must know that an inscribed angle equals 1/2 of the arc that it intercepts.  

Therefore, because <ABC intercepts arc ADC, we know that

the measure of angle ABC = 1/2 * (measure of Arc ADC)

OR, when the values are substituted into the equation

165 = (1/2) (5)(x-3)

When simplified, this equation equals

330 = 5x - 15

345 = 5x

x = 69

Therefore, your answer is the second option, that x = 69 degrees.
