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

Answer:
<h2>y=7x+10</h2>
Step-by-step explanation:
Step one:
Base fee Charge= $10
Charges per hour= $7
Let the number of hours be x
and let the total charges be y
Step two:
the linear function for the total charges can be represented using the equation of a straight line, which is
y=mx+c
where y= tota charges
m= the charges per hour
x= is the number of hours worked
c= the base fee
Step three:
the equation is
y=7x+10
