Camille asked five of her friends how long they studied for the last math test and what grade they received. She found a linear

regression equation for the data to be y = 9.6x + 65.8, with x representing hours.
What does the 9.6 and the 65.8 mean in the context of this equation?
A) 9.6 = the lowest score you can get;
65.8 = the highest score you can get
B) 9.6 = the number of points you would increase each hour of studying;
65.8 = your score if you studied 0 hours
C) 9.6 = the number of points you would increase each hour of studying;
65.8 = the highest score you can get
D) 9.6 = the number of hours you studied;
65.8 = your score if you studied 0 hours

Answer:

B. 9.6 = the number of points you would increase each hour of studying;

65.8 = your score if you studied 0 hours

Step-by-step explanation:

A linear regression equation y = 9.6x + 65.8, with x representing hours.

When x = 0, then y = 65.8. This means

65.8 = your score if you studied 0 hours

When x = 1, then

y=9.6+65.8=75.4

is your score after studying one hour.

The score increased by 75.4-65.8=9.6, so

9.6 = the number of points you would increase each hour of studying.

To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...
To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
To find the y-intercept, set x = 0 \displaystyle x=0 x=0.


Hope this helped brainliest is appreciated

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50
Vsevolod [243]

Answer: The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Step-by-step explanation:

Hi, to answer this question we have to analyze the equation given:

3.00 + 0.50 m = 9.50

Where m is the number of miles.

The equation states that the fixed fee charged (3.00) plus the product of the value of each mile traveled (0.50) and the number of miles traveled (m); is equal to 9.50.

So, the correct statements are:

  • The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
  • Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Feel free to ask for more if needed or if you did not understand something.
