The regression equation for change in temperature, y, to amount of humidity in
mr_godi [17]

Answer:

Residual = 11.462

Since the residual is positive, it means it is above the regression line.

Step-by-step explanation:

The residual is simply the difference between the observed y-value which is gotten from the scatter plot and the predicted y-value which is gotten from regression equation line.

The predicted y-value is given as 20.7°

The regression equation for temperature change is given as;

y^ = 9.1 + 0.6h

h is the observed amount of humidity and it's given to be 23 percent or 0.23.

Thus;

y^ = 9.1 + 0.6(0.23)

y^ = 9.238

Thus:

Residual = 20.7 - 9.238

Residual = 11.462

Since the residual is positive, it means it is above the regression line.

15. Find the force on an electron crossing a uniform magnetic field of intensity 0.5 T WILII
EleoNora [17]

Answer:

F = 8.48 x 10^{-18} N

Step-by-step explanation:

The force on an electron in a magnetic field can be determined by;

F = qvB Sin θ

where: e is the electron, v is its velocity, B is the measure of the magnetic field, and θ is the angle of its path.

Thus,

q = -1.6 x 10^{-19} C

v = 106 m/s

B = 0.5 T

θ = 90^{o}

So that,

F = 1.6 x 10^{-19} x 106 x 0.5

  = 8.48 x 10^{-18} N

The force on the electron crossing the uniform magnetic field is 8.48 x 10^{-18} N.
