Answer: n = 11
Step-by-step explanation:
2^10 = 1,024
1,025 + 1,025 = 2,048
2^11 = 2,048
Answer:
x=-4, y=15
Step-by-step explanation:
3x+y=3
2x+y=7
Multiply top by -1
-3x-y=-3
2x+y=7
Add equations together
-x=4
x=-4
Plug x=-4 into any equation
3(-4)+y=3
-12+y=3
y=15
The answer would be C. Move eight units right on the X axis and two units down on the Y axis.
Answer:
the residual is 0.2032
Step-by-step explanation:
The regression line has been given as:
Y^ = 0.00753X-0.06759
The paired observation for X is (31, 0.369)
The value of X is the empathy score under subject 15 = 31
The value of the brain activity under subject 15 is 0.369
So we have y^ = 0.00753(31) - 0.06759
= 0.1658
Then the residual = y - y^
= 0.369 - 0.1658
= 0.2032
Therefore the residual is 0.2032
