Answer:

<h3>"In a linear regression model, the variable that is being predicted or explained is known as <u>_dependent variable</u> It is denoted by y and is often referred to as the response variable".</h3>

Step-by-step explanation:

Given that "In a linear regression model, the variable that is being predicted or explained is known as <u>dependent variable</u> It is denoted by y and is often referred to as the response variable".

  • Because linear regression models for variables are used to explain or predict the relationship between two variables.
  • The variable in the given model that is being predicted is called the dependent variable.

A.) The formula for the volume of a sphere is given below and the relationship between the radius r and the diameter d is r=d/2.
Tasya [4]

Answer:

\displaystyle V=\frac{4}{81}\cdot \pi\ cm^3

Step-by-step explanation:

<u>The Volume of a Sphere </u>

The volume of a sphere of radius r is given by:

\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3

A. )

If the diameter of the sphere is d, the radius is r=d/2. Substituting:

\displaystyle V=\frac{4}{3}\cdot \pi\cdot \left (\frac{d}{2}  \right )^3

Operating

\displaystyle V=\frac{4}{3}\cdot \pi\cdot \frac{d^3}{8}

Simplifying

\displaystyle V=\frac{1}{6}\cdot \pi\cdot d^3

B.)

The diameter of the sphere is 2/3 cm, thus the volume is:

\displaystyle V=\frac{1}{6}\cdot \pi\cdot \left (\frac{2}{3}  \right )^3

Operating:

\displaystyle V=\frac{1}{6}\cdot \pi\cdot \frac{8}{27}

\displaystyle V=\frac{8}{27}\frac{1}{6}\cdot \pi

\boxed{\displaystyle V=\frac{4}{81}\cdot \pi\ cm^3}

Find the solution to the system of equations.
VARVARA [1.3K]

Answer:

(2,3)

Step-by-step explanation:

use the equal values method.

set y equal to itself.

y = -2x+7 but also 5x-7

-2x+7=5x-7   ............................. solve the equation

7x=14

x=2

Now substitute the x value into one of the equations given. for example i'll do -2x+7.

-2(2) +7 =y

-4+7=y

3=y

so thats your answer

x=2, y=3

(2,3)
