W = 17/13.
I hope this helps. I'm pretty sure I got it wrong, but just let me know.
Answer:
$514.50
Step-by-step explanation:
7+4+2+8=21
$12.25x21=$514.50
Answer:
A)3.74
B)17.04
C)61.92
Step-by-step explanation:
The equation of the line of best fit:

Where x is time in hours
y = midterm score
a)For an increase of one hour in the time spent studying, what is the predicted increase in the midterm score?
General equation y = mx+c
where m is the slope .
On comparing m = 3.74
Slope is the rate of increase per hour
So, For an increase of one hour in the time spent studying, the predicted increase in the midterm score is 3.74
b)What is the predicted midterm score for a student who doesn't spend any time studying?
Substitute x = 0
y=3.74x+17.04
y=3.74(0)+17.04
y=17.04
c)What is the predicted midterm score for a student who studies for 12 hours?
Substitute x = 12
So,y=3.74x+17.04
y=3.74(12)+17.04
y=61.92
Answer: A
When x=1 or 8, the value of the expression does not equal to zero.
Remember
that the circle formula is (x – h)2 + (y – k)2 = r<span>2 where h and
k represents the center of the circle. We determine as follows:
</span><span>A.(x - 2)2 + (y + 7)2 =64
</span><span> (h,k) = 2,-7 QUADRANT 4
</span><span>B.(x - 5)2 + (y + 5)2 = 9
</span><span>
(h,k)
= 5,-7 QUADRANT 4</span>
<span>C.(x - 9)2 + (y + 9)2 = 16
</span>(h,k) = 9,-9 QUADRANT 4
<span>D.(x - 12)2 + (y + 0)2 = 72
</span><span>
(h,k)
= 12,0 QUADRANT 4</span>
