Answer:
The correlation between the Math SAT and the Verbal SAT computed from the data on all the individuals who took the tests would be less than 0.97.
Step-by-step explanation:
Averaging data into blocks (in this scenario, by State) tends to a reduction in variation and an increase in correlation between the studied variables. Therefore, when applying regression to the original individual data, a reduced correlation would be expected:
Therefore, the correlation between the Math SAT and the Verbal SAT computed from the data on all the individuals who took the tests would be less than 0.97.
Answer:
no solutions
Step-by-step explanation:
10x+2y=42
5x+y=20
Multiply the second equation by -2 to use elimination
-2(5x+y)=20*-2
-10x -2y = -40
Add this to the first equation
10x+2y=42
-10x -2y = -40
--------------------------
0 = 2
This is never true. This means there are no solutions
D) 8. The tens digit is 3 and the tenths digit is 5. Add them and you get 8 (your answer)
The answer is
-26 & -25
it's sum = -26+(-25
= -26-25
= -51
