Use compatible numbers to estimate the correct quotient.
The estimate of the quotient expression using compatible numbers is 100
How to estimate the number of quotient?From the question, we have the following parameters that can be used in our computation:
7 | 497
This quotient expression from the question can be expressed as
497 ÷ 7
From the question, we are to make use of compatible numbers
This means that we have the following approximation
497 = 500
7 = 5
Next, we estimate the quotient using approximated values
So, we have
497 ÷ 7 = 500 ÷ 5
Evaluate the quotient
497 ÷ 7 = 100
Hence, the estimate is 100

pls help super easyy due tomm!!!
If a < b, then multiplying both sides of the inequality by -4 will reverse the direction of the inequality. The resulting inequality will be:
-4a > -4b
This is because multiplying a negative number by a negative number results in a positive number, and multiplying a positive number by a negative number results in a negative number. Therefore, the inequality must be reversed when both sides are multiplied by a negative number.
Two student clubs were selling t-shirts and school notebooks to raise money for an upcoming school event. In the first few minutes, club A sold 2 t-shirts and 3 notebooks, and made $40. Club B sold 1 t-shirt and 1 notebook, for a total of $16.
A matrix with 2 rows and 2 columns, where row 1 is 2 and 3 and row 2 is 1 and 1, is multiplied by matrix with 2 rows and 1 column, where row 1 is x and row 2 is y, equals a matrix with 2 rows and 1 column, where row 1 is 40 and row 2 is 16.
Use matrices to solve the equation and determine how many of each item were sold. Show or explain all necessary steps.
The value of the matrix multiplication A x B is matrix C
The value of B is [tex]B = \begin{pmatrix}x\\ y\end{pmatrix} = \begin{pmatrix}8\\ 8\end{pmatrix}[/tex]
What is multiplication of matrices?
The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix
Given data ,
The number of shirts sold by club A = 2
The number of notebooks sold by club A = 3
The number of shirts sold by club B = 1
The number of notebooks sold by club B = 1
Now , the value of matrix A is
[tex]A = \begin{pmatrix}2&3\\ 1&1\end{pmatrix}[/tex]
The value of matrix B is
[tex]B = \begin{pmatrix}x\\ y\end{pmatrix}[/tex]
The product of matrix A and B will be C , and the value of matrix C is
[tex]C = \begin{pmatrix}40\\ 16\end{pmatrix}[/tex]
So , the equation is
A x B = C
Substituting the values in the equation , we get
[tex]\begin{pmatrix}2&3\\ 1&1\end{pmatrix}\begin{pmatrix}x\\ y\end{pmatrix}=\begin{pmatrix}40\\ 16\end{pmatrix}[/tex]
On simplifying the equation , we get
[tex]\begin{pmatrix}2x+3y\\ x+y\end{pmatrix}=\begin{pmatrix}40\\ 16\end{pmatrix}[/tex]
So , the equations are
2x + 3y = 40 be equation (1)
x + y = 16 be equation (2)
Multiply equation (2) with 2 , we get
2x + 2y = 32 be equation (3)
Now , subtracting equation (3) from equation (1) , we get
y = 8
Substituting the value for y in equation (2) , we get
x + 8 = 16
Subtracting 8 on both sides of the equation , we get
x = 8
Therefore , the value of x is 8 and y is 8
Hence , the value of matrix B is [tex]B = \begin{pmatrix}x\\ y\end{pmatrix} = \begin{pmatrix}8\\ 8\end{pmatrix}[/tex]

h(x) = −7x² + 10x - 5
Answer: The expression you provided is a quadratic function in the form of H(x) = ax^2 + bx + c, where a = -7, b = 10, and c = -5. The graph of this function is a parabola with the vertex located at x = -b/2a = -10/(-14) = 5/7. The y-coordinate of the vertex can be found by plugging the x-coordinate into the original function, giving us H(5/7) = (-7)(5/7)^2 + 10(5/7) - 5 = -5/7 + 25/7 - 5 = 0. This means that the vertex of the parabola is located at the point (5/7, 0). The general form of the quadratic function is H(x) = -7(x - 5/7)^2.
What are the solutions to this quadratic equation? Select all that apply. x2 – 3x – 18 = 0 A. x = 6 B. x = –3 C. x = –2 D. x = 9 E. x = –18 F. x = 3
The solutions of the quadratic equation x² - 3x - 18 = 0 are
x = -3 and x = 6
What is Factorization method?
Factorization of a quadratic equation means writing the given expression as a product of its factors. These factors can be numbers, variables, or an algebraic expression.
According to the given question:
The given quadratic equation is x² - 3x - 18
Applying factorization by splitting middle term method
x² - 3x - 18 = 0
x² - 6x + 3x - 18 = 0
Grouping the terms to get
x(x - 6) + 3(x - 6) = 0
(x + 3)(x - 6) = 0
Hence the solutions are x + 3 = 0 and x - 6 = 0
The solutions of the quadratic equation x² - 3x - 18 = 0 are
x = -3 and x = 6

Match the linear equation to the correct graph.
Answer: y= 1/2x + 2
Step-by-step explanation:
The linear equation is y= mx + b
The y-intercept is located at (0,2), so b equal to 2
Let's pick two points ( 0,2) ( 2, 1)
To find the slope, we need to find the rise over run.
Rise decrease by 1, and run increase by 2, so the slope is 1/2
So the equation is y= 1/2x +2

what does the univariate t test tell you that the bivariate correlation test alone does not? what does the bivariate test tell you that the univariate test does not tell you?
In univariate data, only one variable is assessed for each person. Two variables are measured for each person in bivariate data.
The definition of univariable data is "one variable," and it is generally understood to be one sort of data. It is one of the straightforward methods for data analysis. The data in univariable data only include one variable.
The cat's weight, for instance, is 10, 15, 25, 27, 30, 35, and 40.
The variable is hence "Cat weight."
The definition of bivariate data is "Two Variable," and it essentially consists of two different forms of data. It is a straightforward type of statistical analysis.
Only one variable is analysed at a time in univariate statistics. Two variables are compared in bivariate statistics. Multiple variables are compared using multivariate statistics.
In a bivariate analysis, the correlations between the two variables are measured. When there are more than two variables in the data set, a more complicated statistical analysis technique called multivariate analysis is utilized.
Therefore,
In univariate data, only one variable is assessed for each person. Two variables are measured for each person in bivariate data.

The symbol for parallel lines is represented by two tiny parallel lines when written in geometric shorthand, as this ║. For instance, we write JI║NX to indicate that lines JI and NX are parallel. A transversal line is one that runs parallel to another line. The transversal forms eight angles when cutting across parallel lines.

A = -x² + 20 is a quadratic function in standard form that depicts each area as a function of width.
What makes anything a quadratic function?A quadratic in mathematics is a particular kind of problem that involves squaring, or multiplying a variable by itself. This terminology comes from the fact that a square's area equals the product of its side length and itself. Quadratum, the Greek word meaning square, is where the word "quadratic" originates.
Briefing:Now, give the x and y labels to the two sides.
We are aware that a rectangle's area is;
A = length * width
Thus;
A = xy
Given that she has 40 feet of fencing, the following follows:
y = 0.5(40) - x
y = 20 - x
Consequently, the area in the quadratic function formula is;
A = x(20 - x)
A = 20x - x²
A = -x² + 20

In the given Isosceles trapezoid, the value of x and y is 12 and 5 respectively.
What is Isosceles trapezoid?An isosceles trapezoid, or isosceles trapezium in British English, is a convex quadrilateral in Euclidean geometry that has a line of symmetry cutting through one pair of opposite sides.
It is an uncommon instance of a trapezoid.
Alternately, it can be described as a trapezoid with equal amounts of both the base angles and the legs.
Note that the second requirement, or the fact that it lacks a line of symmetry, prevents a non-rectangular parallelogram from being an isosceles trapezoid.
Two opposite sides (the bases) of each isosceles trapezoid are parallel, while the remaining two sides (the legs) are each the same length (properties shared with the parallelogram).
So, solve for x and y:
For x:
4x - 27 = x + 9
3x = 36
x = 36/3
x = 12
For y:
3y + 19 = 11y - 21
8y = 19 + 21
8y = 40
y = 40/8
y = 5
Therefore, in the given Isosceles trapezoid, the value of x and y is 12 and 5 respectively.
