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:
Yes, distance in yards can be obtained by multiplication.
Step-by-step explanation:
Given that the distance between tow points is 90 feets, The distance between these two points in yards can be obtained either by multiplication or division.
I foot = 0.3333 yards
To convert distance between the second and third bases from feet to yard ;
Multiply distance in feets by 0.3333 to obtain the corresponding distance in yards ;
90 * 0.3333 = 29.997 = 30 yards
Answer:
Step-by-step explanation:
Hi Sorry this took so long!
1. True
A=hbb
/2 or Half of Base times Height.
2.False it would be 63
A= b * h
3.True
A=a+b/2 * h
Hope this helps!
5% tax of 135.69
Multiply 135.69 * .05 = 6.7845
5% tax of 135.69 is 6.78
135.69+6.78=142.47
14*3=42
142.47 + 42 = 184.47
Gary will pay $184.47 in all.
Hope this helps you! (:
