Answer:
Let's simplify step-by-step.
(3)(3)−(19)(2)+kx−30
=9+−38+kx+−30
Combine Like Terms:
=9+−38+kx+−30
=(kx)+(9+−38+−30)
=kx+−59
Answer:
=kx−59
_ * 5 > 5
3/3 is equal to 1 which would make them equal to each other.
2/3 is less than one which means it would make the number on the left less than 5, not greater than.
the answer is 5/3 because it is bigger than the other answer choices and will result in a greater number than that on the right.
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)
