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

Hello!</h2>
The answer is:
The correct option is:
A. $0.49
<h2>
Why?</h2>
From the statement, we know that the iHome is used on average three hours a day, and we are asked to find the cost for a week, so first, we need to calculate the total hours that the iHome is used for, and then, calculate the kilowatt-hour consumption rate.
Now, we must remember that:
So,
Then, calculating the cost, we have:
Hence, we have that the correct option is:
A. $0.49
Have a nice day!
I think the answer is 2 parts rice. If you added half to the beans, do it to the rice too.
AS North Korea is generally closed off the foreigners, the Nato nations & others can only guess how much nukes the NK have. Due to reports of missiles flying & landing in water, we can interpret that they have more than 1 missile. However, we believe that they have less than 100 still
1 < x < 100
this means that x is greater than 1, yet less than 100.
hope this helps
