Answer:
c) 
Step-by-step explanation:
Equation for regression line of y on x is given as
where
= predicted value
m = slope of line
b = intercept
m and b are found as
r = correlation coefficient = 0.88
Sx = standard deviation for independent variable x = 13
Sy = standard deviation for dependent variable y = 27
= mean value of independent variable x = 21
= mean value of dependent variable y = 55
Substituting these values in (2) and (3)
Putting these values of m and b in (1)
To solve the problem, do the problem in the parenthesis () then do your answer with the numbers outside the ().
(8-3) = 5 x 3 = 15
(6 + 4) = 10 / 2 = 5
(6 - 4) = 2 / 2 = 1
(6 x 4) = 24 / 2 = 3
Um... part of the (6 4) doesn't make sense... What goes between the numbers? Plus, minus, multiply or division sign? Please tell.
But, I already got you started off and I'll let you figure out the rest. (If you can not figure out the rest, please tell me what sign is between the 6 and 4 in (6 4) and then I'll give you the answer and a better explanation.)
I hope this helps! :D
6 because 6x6=36
-------------------
100 times 100
When you want to multiply 100 by 100, count up all the zeros first.
There are 2 zeros in one 100 and 4 zeros in two 100's.
Since there are 4 zeros, that means 100 • 100 is a 1 followed by 4 zeros.
This means 100 • 100 = 10,000
100 multiplied by 100 is 10,000 (ten thousand)
Hope this helps!
