Answer:
448in^2
Step-by-step explanation:
The area of a trapezoid is the bases added divided by two times the height.
(32+24)/2*16=28*16=448 in^2
Answer:
7x^2a
Step-by-step explanation:
7x^3a+7x^2a^2
7x^3a = 7 xxxa
7x^2a^2= 7 xxaa
The common terms are 7xxa
7x^2a
This is the greatest common factor
Answer:
a)
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
b)
Now we can find the means for x and y like this:
So the line would be given by:
Step-by-step explanation:
Part a
The correlation coeffcient is given by this formula:
For our case we have this:
n=4
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
Part b
Where:
With these we can find the sums:
And the slope would be:
Now we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
