Answer:
Khan Academy is a great website for Algebra l math
If you have the time and money Kumon is a good in-person learning assistance (I-H level is about algebra I)
Step-by-step explanation:
Answer:
Positive exponent
Step-by-step explanation:
Like x root 1 , 2 , 3 etc
If it said negative exponent then x root -1, -2 etc etc.
Answer:
the numerical value of the correlation between percent of classes attended and grade index is r = 0.4
Step-by-step explanation:
Given the data in the question;
we know that;
the coefficient of determination is r²
while the correlation coefficient is defined as r = √(r²)
The coefficient of determination tells us the percentage of the variation in y by the corresponding variation in x.
Now, given that class attendance explained 16% of the variation in grade index among the students.
so
coefficient of determination is r² = 16%
The correlation coefficient between percent of classes attended and grade index will be;
r = √(r²)
r = √( 16% )
r = √( 0.16 )
r = 0.4
Therefore, the numerical value of the correlation between percent of classes attended and grade index is r = 0.4
I hope this helps you
9=n.n
3.3=n.n
n=3
3(2x - 1) - 2(3x + 4) = 11x
- Distribute 3 inside the parentheses.
6x - 3 - 2(3x + 4) = 11x
- Distribute 2 inside the parentheses.
6x - 3 - 6x - 8 = 11x
-11 = 11x
<h3>x = -1</h3>
