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.

Phantasy [73]

Answer:

A) 25

Step-by-step explanation:

You use x= -b/2a in order to get your maximum so x= -10/ 2(-5) and you get x=1. You plug 1 into the function as h(1)=-5(1)^2 + 10(1)+ 20 which gets you 25

11. What is the value of x in the figure at the right? (Examples 3 and 4)
natka813 [3]

Answer:

x = 11

Step-by-step explanation:

  • Vertically opposite angles are equal
  • Angles around a point add up to 360°

Therefore, 15x + 15x + 15 + 15 = 360

\implies 30x+30=360

\implies 30x=330

\implies x=11

Is the answer 24 ?? Someone please help
ELEN [110]
Yes the answer is 24 cm2
because the width is 4 cm then 2 width = 2(4) = 8 cm
perimeter = 20 cm
20-8=12 cm
so 12 cm left is 2 length then the length is 12/2= 6;cm
that's why the area is 4*6= 24 cm2
