Answer:
B
Step-by-step explanation:
We want to find the quadratic regression formula given the table.
So, let's use the quadratic regression function on your graphing calculator. I don't have one on me, but I believe you simply need to enter the data and hit quadratic regression or something similar.
I'm going to use an online quadratic regression calculator by Keisan Casio.
Refer to the screenshot.
Note that it says to use the 24-hour clock to represent time after noon. So, 2 P.M. will just be 14, 4 P.M. will be 16, etc.
Therefore, our quadratic regression equation is, approximately:
The choice that <em>best</em> represents this is B.
So, our answer is B.
And we're done!
Answer:slope=1.2
Step-by-step explanation:
Slope=y-y/x-x
=1-(-5)/7-2
= 6/5
=1.2
2.1S + 4.8H = 2808
H = 2S
2.1S + 4.8(2S) = 2808
2.1S + 9.6S = 2808
11.7S = 2808
S = 2808/11.7
S = 240
H = 2S
H = 2(240)
H = 480
so the standard version (S) has 240 downloads and the high quality version (H) has 480 downloads
C, line equations are not about degrees. Line equation are fill with integers.
