Answer:
And for this case ![r =0.45](https://tex.z-dn.net/?f=%20r%20%3D0.45)
The % of variation is given by the determination coefficient given by
and on this case
, so then the % of variation explained is 20.25%.
The proportion of the variability seen in final grade performance that can be predicted by math ability scores is 20.25%.
Step-by-step explanation:
For this case we asume that we fit a linear model:
![y = mx+b](https://tex.z-dn.net/?f=%20y%20%3D%20mx%2Bb)
Where y represent the final grade and x the math ability scores
Where:
And we can find the intercept using this:
The correlation coeffcient is given by:

Answer:
no it is not
a whole number is a number with that is a multiple of 1
ex 1,6,4
but not 2/3,-5.5,-225
if we simplfy -7/2 we get -3.5
Hope This Helps!!!
Answer:
I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.

<span>the number 57,733 contains two sets of digits in which one digit is ten times as great than the other. what are the values of the digits in each set? Answer: 7000 & 30 </span>
3x^2 + 6x - 24
3(x^2 + 2x - 8)
3(x + 4)(x - 2) <==
