Answer:
And for this case
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:
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:
And for this case
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%.
X=7
add 3 to both sides.
hope this helps!
Answer:
a. 22.5953 b. 3.6
Step-by-step explanation:
A. When a number is in parentheses and directly beside another number it means multiple. so you simply multiply to two together.
B. When a number is in parentheses but has a division sign or forward slash in front of it it is simply keeping the number separate as not to create confusion so just divide them.
ps. when you teacher says shoe work he/she means dint just write an answer. They mean write out beside your answer "2.43 x 9.71 = 22.5953" & "4.68 ÷ 1.3 = 3.6"
3a - 6=5a +4
then you would subtract 3a on both sides to get
-6=2a+4
then you would subtract 4 on both sides to get
-10=2a
divide 2 into -10 and get
a= -5
C)!!!! Probably too late? ;)
