Can some one help me Please?Tracy wants to find out if her math test scores are related to the
number of hours she studies for the tests

which is the dependent variable in the experiment?

A. hours studied

B. test scores

Please let me know in the comments

Answers

Answer 1
Answer: In independent variable would be the hours studied, because it doesn't depend any anything. The dependent variable would be the test scores, as they all tie into each other. 

Answer: B. test scores
Answer 2
Answer: B Is the correct answer ,  Because you have to study for the test in order to  take the test , so her studying will show up on her test. its the dependent variable

dose this help?

All she needed was 8 cups should I explain

In your own words, explain the steps you would need to take to find slope from data in a table. The sample response is… Start by choosing two data points. Calculate the difference between the second y value and the first y value. Then divide that by the difference between the second x value and the first x value.

But at the end it says you should include this info… Choose two sets of data (x and y values). Calculate the difference between the two y values. Calculate the difference between the corresponding two x values. Slope is the difference in y values / difference in x values.

Use this information to your advantage.
Hope this helps! :))

Answer:

Take two pairs for example (1,1) and (2,2) and then put y coordinates over x coordinates in like a fraction and then subtract them. Once the y coordinate have been subtracted from each other and the x coordinates have been subtracted from each other then divide the top from the bottom.

Hope that help. Really sorry if it doesn’t

thank you, this helps a lot!! I think I’m ready for my math test now ☺️

If a test has 95 questions how many points would each question be worth? Using your answer how many could you miss without going below an 80?

Answers

One can miss up to 24 questions and still achieve an 80% score.

In order to calculate the points each question is worth and determine how many questions you can miss while maintaining an 80% score.

To find the points each question is worth, we divide the total points by the number of questions. Let's assume the test is out of 100 points, which is a common scale. Therefore, each question would be worth \((100)/(95)\) or approximately 1.05 points.

Now, let's determine how many questions you can miss while still achieving an 80% score (which is 80 out of 100 points). We'll set up an equation to solve for the maximum number of questions you can miss, denoted by "x":

\(80 = (100 - x)/(95) * 100\)

To solve for "x," first, we'll simplify the equation:

\(80 = (10000 - 100x)/(95)\)

Next, we'll isolate "x" by multiplying both sides by 95:

\(7600 = 10000 - 100x\)

Now, isolate "-100x" by subtracting 7600 from both sides:

\(-2400 = -100x\)

Finally, divide both sides by -100 to solve for "x":

\(x = (-2400)/(-100) = 24\)

So, you can miss up to 24 questions and still achieve an 80% score.

100/95= 1.05. Each question worth 1.1 rounded. You could miss 19 but if you miss 20 you go under 80.

Charlie runs at a speed of 3 yards per second. About how many miles per hour does Charlie run?

Answers

Times 3 by 3,600 and you find out that he runs 10,800 yards per an hour. Now there are 1,760 yards in a mile so if you divide 10,800/1,760 and get 6.14 
So charlie runs 6.14 MPH
