The LSR equation for GPA on IQ is y = 0.10x - 3.49. A student with an IQ of 127 has a GPA of 7.85. Find the predicted GPA and residual for this student. Be sure to label each answer. Also, correctly interpret the slope.

predicted GPA=9.21, residual= 1.36,  a correct value of slope would be 0.09

Step-by-step explanation:

y=0.1x -3.49

y: GPA

x: IQ

y=0.1(127)-3.49

y= 9.21

Predicted GPA= 9.21

residual= 9.21- 7.85= 1.36

The equation doesn't model the exact relationship between GPA and IQ.

A better slope value could be

7.85= m(127)-3.49

m=0.09

answer: 12

step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
