Answer:
a) True
b)False
c)False
d)False
e)False
Step-by-step explanation:
Correlation is a statistical technique that help us to know relation between two variables.
a) True
it is correct to say as a negative correlation means that there is an inverse relation between the two variables.
b) False
The coefficient of determination, , can never have a negative value because it is square of coefficient of regression and a squared value can never be negative.
c)False
The variable to be determined is dependent variable and its value depend on the independent variables.
d)False
The value of correlation coefficient must be zero. A negative correlation means that there exist an inverse relation.
e)False
It ranges from -1 to 1.
(See attached diagram.) The positions of the vaulter's left and right hands are marked. The length of the entire pole is 15 feet. The segment below her left hand is twice as long as the segment above, so label those two parts with x and 2x. Those two segments add up to 15 feet:
The lower segment is 10 feet long. The vaulter's right hand is 1.5 feet above her left, so it is 10 + 1.5 = 11.5 from the bottom of the pole.
Answer is D because the rate can not be changed
Step-by-step explanation:
-8 ( - 5 + 13) + 2 : 1 x 2
-8 ( 8) + 2 : 2
-64 + 1
-63
Well I think it's c+m=152
