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
Answer:
19.5
Step-by-step explanation:
I'm presuming the scale factor's 1.75/1
14*1.75=21.5
21.5-2=19.5

Answer:
d is less than or equal to 6
Step-by-step explanation:
Treat it like a normal equals equation like d/3=2. In that case just multiply both sides by 3 and you get d=6, but then substitute the less than or equals sign for the equals sign which means d is less than or equal to 6.
