The difference between the actual value of the response variable and the corresponding predicted value(regression error) using the multiple regression model is the correct option.
A residual is a measurement of the vertical distance between a point and the regression line. It is just the discrepancy between an actual value observed and a value that was projected.
To ensure that the requirements for making conclusions about the coefficients in a linear model have been met, one should always perform a residual analysis.
In regression analysis, a residual is the discrepancy between an observed value and a predicted value.
It is determined by,
Residual = Observed value – Predicted value
The residual is the discrepancy between the expected value and the actual value.
Observed value minus predicted value equals residual.

make an inequality.
She can spend a maximum of $2763.
How to calculate how much can she afford to spend on Furniture?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression.
The credit card works as there can be a negative balance in the card. For example if Sally has a shortage of money and she is in need of some, she can take money from her credit card and then repay it later.
Sally already has $763 in her possession in this situation, and her credit card can only have a $2000 balance.
So Sally can spend $763 which she already has in her hand and then spend a maximum of $2000 using her credit card.
Given,
credit card limit = 2000
current balance = 763
2000+763=2763
So She can spend a maximum of $2763.

The value of m∠T in the triangle is 65°
How to find m∠T in the triangle?
The congruence of any two figures is generally understood as two figures which can perfectly overlap each other. Congruent triangles are triangles that are perfect copies of one another.
Given: ΔABC and ΔRST
If the two triangles ABC and RST are arranged, two angles and a side of one are respectively equal to two angles and the corresponding side of the other (AAS). Thus, the triangles are congruent. This implies:
∠A = ∠R, ∠B = ∠S, |AB| = |RS| .Also, ∠C = ∠T, |AC| = |RT| and |BC| = |ST|
Thus, <R = 41°, ∠S = 74°,
<R + ∠S + ∠T = 180° (Sum of angle in a triangle)
41 + 74 + ∠T = 180
115 + ∠T = 180
∠T = 180 - 115
∠T = 65°
Therefore, m∠T = 65°

20x-45y=650 solve for x
Answer:
x = 45y + 650/2
Step-by-step explanation:
20x - 45y = 650
20x - 45y + 45y = 650 + 45y
20x = 650 + 45y
20x/20 = (650 + 45y)/2
x = 45y + 650/2
Thus, The value of x is 45y + 650/2

What is an equation?
In mathematics, an equation is a formula that expresses equality by connecting two expressions with an equal sign. Equations and their cousins in other languages may have subtly different meanings. For example, in French an equation is defined as containing one or more variables, whereas in English any well-formed expression consisting of two expressions joined by an equal sign is an equation.
To solve an equation involving variables, it is necessary to determine which values of the variables make the equation true. The variables for which the equation must be solved are also called unknowns, and the values of the unknowns that satisfy the equation are called the solution of the equation. There are two types of equations: identities and constraints. The ID applies to all values of the variable. Constraint expressions apply only to specific values of variables.
Therefore, The answer for this equation is true.

What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
Both mathematical phrases, equations, and inequalities are created by connecting two expressions.
The equal sign (=) indicates that two expressions in an equation are believed to be equivalent.
The symbols >,<, ≥, ≤ or ≠ indicate that the two expressions in inequality are not always equal.
So, initial payment = $35
$12 in additional fees for each class
The minimum goal is $100.
There are C classes in total.

What is solving an equation?
A General Rule for Equation Solving:
Simplify each side of the equation by removing parentheses and combining like terms.
To separate the variable term on one side of the equation, use addition or subtraction.
To find the variable, use division or multiplication.
Given;
√3x + 2 = 3√2x - 2
⇒
3√2x - √3x = 2 + 2
(3√2 - √3)x = 4

A popular act commands $250,000 for a single appearance plus 20% of ticket sales and 10% of concession receipts. If ticket sales are $1,250,000 and concession receipts are $400,000, what will the act be paid for their performance?.
The required will the act be paid for their performance is $540,000.
Explain percentage.In mathematics, a percentage is a number or ratio that can be communicated as a negligible portion of 100. In the event that we need to compute percent of a number, partition the number by the entire and duplicate by 100. Consequently, the rate implies, a section for every hundred
How will the act be popular paid for their performance?The total amount that should be paid is the sum of the single appearance fee, the 20% of ticket sales and the 10% of concession receipts.
We have,
single appearance = $250,000
sales =$1,250,000
concession receipts = $400,000
Total amount = single appearance + (10% of sales) + (10% ofconcession receipts)
Then,
Total amount = $250,000 + (20% x 1,250,000) + (10% x $400,000) = $540,000
Thus, required total amount is $540,000.
