Answer: 8.7
Step-by-step explanation:
Given:
hypotenuse = 9
Angle x =75
opposite of angle = x
Solution:
From SOH CAH TOA, use SOH
sin x = \(\frac{opposite}{hypotenuse}\) > substitute
sin 75 = \(\frac{x}{9}\) > multiply both sides by 9
9*sin 75 =x
x=8.7

What is the image point of (2,8) after the transformation rx-axis D₂?
After transformation, the point (-1,2) in the image would be (-1,-2)
What is composition of transformations?Each transformation applied to the prior image is combined into a composition of transformations. The result of a translation is identical to a composition of reflections across parallel lines (twice the distance between the parallel lines). The composite transformation is carried out by multiplying the matrix in order from the right to the left side if it is represented as a column. The output from the preceding matrix is multiplied by the new matrix that will follow.
First, we must mirror the point (-1, 2) around the line y=-x.
(X, Y) is the rule (-y,-x)
you obtain (-1,2)—>(-2,1) (-2,1)
At this point, you must rotate (-2,1) by 90 degrees.
(X, Y) is the rule ( -y,x)
so (-2,1)—> (-1,-2) (-1,-2)
After transformation, the point (-1,2) in the image would be (-1,-2)
The complete question is,

The mean score on the quiz was 6.625 with a population standard deviation of 1.9. Which of the following statements best describes the quiz scores? (DOK 3) All of the earned scores are within one standard deviation of the mean. All of the earned scores are within two standard deviations of the mean. All of the earned scores, except for one, is within two standard deviations of the mean. The value of 10 is an outlier so it should be removed from the data set.
The range of the scores is given by :
\(\text{range}=\operatorname{mean}\pm\text{standard deviation}\times1\text{ or 2 or 3}\)For one standard deviation :
\(\text{range}=6.625\pm1.9\times1\)The range is :
6.625 - 1.9 = 4.725
6.625 + 1.9 = 8.525
So it follows that the range of the scores is from 4.725 to 8.525
And it concludes that NOT all scores are within the one standard deviation because the histogram shows a score of 2, 9 and 10.
So choice A is NOT VALID
For two standard deviations :
\(\text{range}=6.625\pm1.9\times2\)The range is :
6.625 - 1.9(2) = 2.825
6.625 + 1.9(2) = 10.425
So it follows that the range of the scores is from 2.825 to 10.425
And it concludes that All of the scores are within the two standard deviation except for the score "2".
So Choice B is also NOT VALID
But the Choice C, will satisfy this condition. For all of the earned scores, except for one, is within two standard deviations of the mean.
So the answer is Choice C or Third Option.
Type the answer in standard form below.

Kelly paid $45.36 for a sweater that was on sale for 25% off the original price. She paid 8% sales tax on the sale price.
What was the original price of the sweater, in dollars
The sales tax is determined by computing a percent of the purchase price. To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price.

A marketing researcher must determine how many telephone numbers she needs to order from a sample provider to complete a survey of ATM users. The goal is to complete 400 interviews with ATM users. From past experience, she estimates that 70 percent of the phone numbers provided will be working phone numbers. The estimated incidence rate (percentage of people contacted who are ATM users) is 45 percent. Finally, she estimates from previous surveys that 37 percent of the people contacted will agree to complete the survey. How many telephone numbers should she order to complete the 400 interviews
Answer:
the required number of telephone orders to complete the 400 interviews is 3433
Step-by-step explanation:
Given the data in the question;
Let us represent the telephone numbers the researcher orders to complete the 400 interviews with Y.
Thus, The working phone numbers = 70% × Y
Now, number of ATM users = 45% × The working ph0ne numbers
⇒ 45% × ( 70% × Y )
number of ATM users = 0.45 × 0.70 × Y = 0.315Y
Thus; Number of people contacted that agrees to complete the survey will be;
⇒ 37% × number of ATM users
⇒ 0.37 × 0.315Y = 0.11655Y
so, since the researcher needs at least 400 interviews
Hence;
0.11655Y ≥ 400
Y ≥ 400 / 0.11655
Y ≥ 3432.0034 ≈ 3433
Therefore, the required number of telephone orders to complete the 400 interviews is 3433

which function will have the greatest value at
\(x = 16 \)
\( y = {10}^{16} \)
\(y = {x}^{2} - 17x + 182\)
\(y = {1.17}^{x} \)
The function that would have the greatest value at x = 16 include the following: B. y = x² - 17x + 182.
How to determine the corresponding output value for the given function?In Mathematics and Geometry, a function is a mathematical equation which defines and represents the relationship that exists between two or more variables such as an ordered pair in tables or relations.
In this exercise, we would determine the corresponding output value for this function of y based on the x-value (x = 16) in simplified form as follows;
\(y = 10^{16}\)
y = 10,000,000,000,000,000.
y = x² - 17x + 182
y = 16² - 17(16) + 182
y = 256 - 272 + 182
y = 166.
\(y = 1.17^x\\\\y = 1.17^{16}\)
y = 12.330304108137675851908392069373.
