Briefly explain how multiple regression enhances the two primary purposes of regression analysis.

Answers

Answer 1

The statistical goal of multiple regression analysis is to build a linear equation model that identifies the optimal weighted linear combination of independent variables in the study in order to optimally predict the reference variable.

Regression analysis is usually performed for one of two purposes. Predicting the value of the dependent variable of a person whose information about the explanatory variable is available, or estimating the effect of the explanatory variable on the dependent variable.

In multiple regression analysis, researchers can determine the strength of the relationship between the outcome (dependent variable) and multiple predictors, and the importance of each predictor in the relationship, often the effect of other predictors. It can be evaluated by statistically eliminating it.

The coordinate of the point C from the given triangle ABC after translation is C' = (4, -2)

Translation of coordinates

A triangle is a 2D figure with 3 sides and angles. Given the coordinate C points of the triangle;

C = (-2, -3)

If these coordinate point is translated 6 units to the right and 1 units up, the resulting coordinate will be at:

C' = (-2 + 6, -3 + 1)

The cost of renting a canoe L depends on the number of hours t of rental. The cost is $17 per rental hour.

Answers

Answer:

Option 1

Step-by-step explanation:

Hello!

We can see that the base price for a canoe is $12, as you have to spend the $12 to get the canoe.

You also have to spend $5 per hour in the canoe, which is why "t" is being multiplied by 5.

We can also look at this graphically.

The x-axis is the number of hours, while the y-axis is the price. When x is 0 (no hours on canoe), you can see that the price is $12. But as it increases by 1 hour, the price increases by $5.

A Weak (negative) correlation exists between the list price of condominiums and co-ops and the unemployment rate.

The correlation coefficient is a statistical measure of the strength of the connection between the relative actions of two variables. The values varied between -1.0 and 1. zero. A calculated wide variety greater than 1. zero or less than -1.zero means that there was an error within the correlation size.

The correlation coefficient is decided with the aid of dividing the covariance by way of the product of the 2 variables' popular deviations.

Answers

The equation representing the given case is 2(x - 8) = 3(x + 3), where x is the number.

The number satisfying this equation is -25.

In the question, we are asked to find the number when twice the difference of the number and 8 is equal to thrice the sum of the number and 3.

We assume the number to be x.

The expression representing twice the difference between the number and 8, can be shown as 2(x - 8).

The expression representing thrice the sum of the number and 3, can be shown as 3(x + 3).

We are informed that these two expressions are equal. This can be shown as the equation:

2(x - 8) = 3(x + 3).

Thus, the equation representing the given case is 2(x - 8) = 3(x + 3), where x is the number.

Now, to find the number, we solve the equation as follows:

2(x - 8) = 3(x + 3),

or, 2x - 16 = 3x + 9 {Simplifying},

or, 2x - 16 + (16 - 3x) = 3x + 9 + (16 - 3x) {Adding (16 - 3x) to both sides of the equation},

or, 2x - 16 + 16 - 3x = 3x + 9 + 16 - 3x {Simplifying},

or, -x = 25 {Simplifying},

or, -x(-1) = 25(-1) {Multiplying both sides of the equation with -1},

or, x = -25 {Simplifying}.

Thus, the number satisfying the equation is -25.

Determine the area of the figure.

Answers

The area of ​​the trapezoid is x+11 cm.

Given a trapezoid has one side of (x+6) cm, the other side is 5 cm, and the height is 2 cm.

A two-dimensional quadrilateral consisting of the sum of non-adjacent parallel sides and a suitable non-parallel side is denoted as a trapezoid.

Now we will use the formula to find the area of ​​a trapezoid

Area = 1/2 × (base 1 + base 2) × height

Here base 1 = (x+6) cm, base 2 = 5cm and height = 2cm

Substituting the values ​​into the formula,  we get

Area = 1/2 × (x+6+5) × 2

Area = 1/2 × (x+11) × 2

Area = x+11

Thus, the area of ​​the given figure when one side is x+6, the other side is 5 cm and the height is 2 cm is x+11 cm.

The product of 8 and the sum of 4 and a number is 112. What is the number?
Which equation could be used to solve for the number?
8 + 4n = 112
O 8 x 4 + n = 112
8(4 + n) = 112

Answers

Answer:

8(4 + n) = 112

Step-by-step explanation:

Let's start by reading the problem since it maybe is a bit confusing at first.

The product of 8

Now we know that it starts with 8 multiplied by another number. We do not know that number yet, so let's put 8 * () and fill in the parentheses later.

So far, our equation is:

8()

.. And the sum of 4 and a number

So, 4 + n

We can enter that into our equation

8(4+n)

The next line says "..Is 112"

So, the solution to our equation is 112

Our equation becomes:

8(4+n)=112
