Answer:

Eight times the **difference **of y and nine will be **8(y - 9).**

It should be noted that eight times the** difference **of y and nine simply means that one has to** subtract **9 from y and then **multiply **the difference by 8.

Therefore, eight times the** difference **of y and nine will be **8(y - 9).**

In conclusion, the correct option is **8(y - 9).**

This is a extremely important geometry im giving brainliest and 50+ points. Provide steps as needed.

Please help!!! Will mark brainliest!!!!!!!! Dan wants to determine the probability that the republican on the ballot will be elected mayor of his town. He surveys a random sample of 25 people in the town who are registered to vote. Based on this data, the republican on the ballot has a 36% probability of being elected. Dan now wants to gauge the variation in predictions, to determine how accurate this probability may be. Which if the following would be the best method for him to do this?A) Ask the same 25 people he originally surveyed to make sure they are convinced of their choicesB) Survey several more random samples of 25 people each from people in the town who are registered to vote C) Survey serveral more random samples of 25 people each from the Republican voters in townD) Survey a random sample of 25 people who are registered to vote in another town

The figure shows two right triangles, each with its longest side on the same line.What is the length of XY?

If f Subscript x(a,b)equals f Subscript y(a,b)equals0, does it follow that f has a local maximum or local minimum at (a,b)? Explain. Choose the correct answer below. A. Yes. The point (a,b) is a critical point and must be a local maximum or local minimum. B. Yes. The tangent plane to f at (a,b) is horizontal. This indicates the presence of a local maximum or a local minimum at (a,b). C. No. One (or both) of f Subscript x and f Subscript y must also not exist at (a,b) to be sure that f has a local maximum or local minimum at (a,b). D. No. It follows that (a,b) is a critical point of f, and (a,b) is a candidate for a local maximum or local minimum.

20.8

20.86

20.9

**Answer:**

20.9 is the answer because To round 20.86 to the nearest tenth consider the hundredths’ value of 20.86, which is 6 and equal or more than 5. Therefore, the tenths value of 20.86 increases by 1 to 9. 20.86 rounded to the nearest tenth = 20.9

a. yes.

b. no.

2. Number of workshops attended.

3. Whether the student passes the course.

a. yes.

b. no.

4. Final exam score Correlation.

**Answer:**

2. Number of workshops attended.

**Step-by-step explanation:**

The variable of interest for predicting the final exam score and doing regression analysis is workshop attendance. Therefore, the response variable should be the number of workshops attended by each student.

This also agrees with what the college tutoring center staff are considering, which forms the research question: "should the center increase the number of math workshops they offer to help students improve their performance in math classes?"
