Empathy means being able to understand what others feel. To see how the brain expresses empathy, researchers recruited 16 couple
yulyashka [42]

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

Please check the attachment for the table, it will aid you in understanding the solution

2Y - 1.7 =3.3 <br><br> HELP !!!!!
bogdanovich [222]

Answer:

2.5

Step-by-step explanation:

Simplifying

2y + -1.7 = 3.3

Reorder the terms:

-1.7 + 2y = 3.3

Solving

-1.7 + 2y = 3.3

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '1.7' to each side of the equation.

-1.7 + 1.7 + 2y = 3.3 + 1.7

Combine like terms: -1.7 + 1.7 = 0.0

0.0 + 2y = 3.3 + 1.7

2y = 3.3 + 1.7

Combine like terms: 3.3 + 1.7 = 5

2y = 5

Divide each side by '2'.

y = 2.5

Simplifying

y = 2.5
