Answer:
Options a, b, c are correct.
Step-by-step explanation:
First let's see the equation that governs the statement, which is the following:
Therefore, reading options a, b, c are correct.
Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.
This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.
that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.
Simplified would be 2a+2b
Answer:
C
Step-by-step explanation:
It is not E becuase SQRT(97) is less than SQRT(100), SQRT(100) is 10,
SQRT(81) is 9 SO SQRT(97) is between 9 and 10, C.
Hope it helps :)
