The point lies directly on the regression line (Apex)
elena55 [62]3 years ago
5 0

Answer:

The correct answer is “the point lies directly on the regression line”

Step-by-step explanation:

When you do a regression analysis, then you get a line of regression that best fits it. The data points usually tend to fall in the regression line, but they do not precisely fall there but around it. A residual is the vertical distance between a data point and the regression line. Every single one of the data points had one residual. If one of this residual is equal to zero, then it means that the regression line truly passes through the point.

An exponential function is expressed in the form y=axb^x. The relation represents a growth when _______ and a decay when ______.
seropon [69]

Answer:

Growth when: b>1.

Decay when: 0<b<1.

Step-by-step explanation:

Any function in the form f(x)=a{\times}b^x , where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b.

If 0 < b < 1 this is an example of an exponential decay.

The general shape of an exponential with b > 1 is an example of exponential growth.

Hence,

An exponential function is expressed in the form f(x)=a{\times}b^x,   The relation represents a growth when  b >1 and a decay when 0<b<1.
