VLD [36.1K]

Answer:

True

Step-by-step explanation:

In regression analysis, it tries to infer that there is a supposed relationship between two or more variables.

Now it has a couple of functions such as;

It allows us to directly estimate the parameters in linear functions only, although there are some other ways in which it would allow many non - linear functional forms to get estimated indirectly.

Regression also allows us to test and find out if there is a functional relationship between two or more variables. This is done by testing the hypothesis whether each of the slopes have a value of zero.

Thus, from the definitions given, we can see that regression is a basically a functional relationship between two or more variables, where one or more variables are used to predict a single variable of interest.

Thus, the given statement is true.

On the scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is
baherus [9]

Answer:

I=\frac{3}{8}\cdot F and F = \frac{8}{3}\cdot I.

Step-by-step explanation:

Let I represent inches and F represent feet.

We have been given that on he scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is 16 feet.

We will use proportions to solve our given problem as:

\frac{\text{Length on scale}}{\text{Actual length}}=\frac{6}{16}

\frac{I}{F}=\frac{6}{16}

Now, let us solve for I.  

I=\frac{6}{16}\cdot F

I=\frac{3}{8}\cdot F

Now, let us solve our equation for F.

I\cdot\frac{8}{3}=\frac{8}{3}\cdot\frac{3}{8}\cdot F

\frac{8}{3}\cdot I= F

F = \frac{8}{3}\cdot I

Therefore, our required equations would be I=\frac{3}{8}\cdot F and F = \frac{8}{3}\cdot I.
