Answer:
The slope to line a is 2,3
The slope to line b is 2,4
Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
Use Pythagorean theorem.
a^2 +b^2 = c^2
4^2 +b^2 = 5^2
16 +b^2 =25
-16 from both sides
b^2 = 9
square root b^2 = square root 9
b = 3
b=x
x=3
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
