The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle you need to go half way around the circle and then across a diagonal to get back to where you started so the perimeter is 1/2 π × d + d.

When the mean value of the dependent variable is independent of variation in the independent variable, the slope of the regressi
miss Akunina [59]

Answer:

zero

Step-by-step explanation:

The optimally fitted straight line via the locations and points on a graph is determined via linear regression. You may use regression equations to see if your data can indeed be fitted into a formula. If you want to create assumptions from your data, either future forecasts or indicators of previous behavior, using the Regression equation is highly beneficial.

The regression line is expressed as:

Y_i = a +bx_i

where;

Y_i = dependent variable

a = intercept

b = slope

x_i = independent variable

So, when Y_i is independent of the variation of x_i, it means that Y_i does not linearly depend on x_i . Thus, the slope of the regression will be zero.
