There is no picture attached to the question??
To simplify by distribution we proceed as follows;
7a(3b-2c+4)
=7a*3b-2c*7a+4*7a
=21ab-14cb+28a
the answer is:
21ab-14cb+28a
Answer:
Step-by-step explanation:
Answer:
The correct option is B.
Step-by-step explanation:
It is given that the correlation coefficient between two variables is -0.95.
Correlation coefficient between two variables is denotes by ρ. The value of ρ is leis between -1 to 1.
If
, then it represent perfect negative correlation.
If
, then it represent perfect positive correlation.
If
, then it represent no relationship between the variables.
Since the -0.95 is near to the value -1, therefore we can say that there is a strong negative association between the variables. Option B is correct.
