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
is your score after studying one hour.
The score increased by 
so
9.6 = the number of points you would increase each hour of studying.
Answer:
No, Jill is incorrect because 23/1000 and 0.23 are not equivalent. But 23/100 is equivalent to 0.23 and 0.023 is equivalent 23/1000
The expression for (r-s)(x) is found by subtracting s from r. That difference is
. The expression for (r+s)(x) is found by adding them, which is
. Now we are told to evaluate (r*s)(x) which means they want us to multiply those and state the "new" expression that results.
. There you go!
