for a rectangle you have to lengths and 2 width so you will have to have 2w+2 and then times 4w+3 which should equal 56

Option A is the dot plots which would most likely have the highest standard

deviation.

This is referred to as the measure of the amount of variation or dispersion of a set of values and the one with a higher standard deviation will usually have its average points farther away from the mean which is located at the center while those with a lower  standard deviation will usually have its average points closer to the mean.

From the options provided , option A has a lot of points on 2 and 14 which are further way from the center (mean) and is therefore the reason why it was chosen as the correct choice.

The coordinate matrix of x relative to an orthonormal basis b in [tex]R^n[/tex] can be found by computing the inner product of x with each basis vector and representing these inner products as the entries of a column vector.

To find the coordinate matrix of x relative to an orthonormal basis b in R^n, we need to express x as a linear combination of the basis vectors in b. This can be done by computing the inner product (dot product) of x with each basis vector and representing these inner products as the entries of a column vector. The resulting vector is the coordinate matrix of x relative to the orthonormal basis b.

For example, let x be a vector in [tex]R^n\\[/tex], b = [tex]{b_1, b_2, ..., b_n}[/tex] be an orthonormal basis in R^n, and let A be the coordinate matrix of x relative to b. Then the entries of A are given by:

A = [tex]( x, b_1 , x, b_2 , ..., x, b_n )^T[/tex] where [tex]x, b_i[/tex] denotes the inner product of x and [tex]b_i[/tex].

It is important to note that the basis b must be orthonormal for the coordinate matrix to have this form, if the basis is not orthonormal, the process will be different.

Then solve it

First solve the number in the bracket

(3)² = 9

Then

4 x 9 + 3 x 7

According to BODMAS, we should solve numbers that need to be multiplied

4 x 9=36

3 x 7= 21

Then add those two numbers

Answer:

[tex]y = \frac{1}{10}x - 1[/tex]

Step-by-step explanation:

We are given the equation x - 10y = 10.

We want to write it in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept, hence the name.

Notice how in slope-intercept form, only y is on one side.

This is because the equation is basically solved for y in slope-intercept form.

So, we should solve the equation for y.

Start by subtracting x from both sides.

x - 10y = 10

-x           -x

_______________

-10y = -x + 10

Now, divide both sides by -10 to isolate y.

-10y = -x + 10

÷10    ÷10

Therefore , the solution to the given problem of triangle comes out to be the length MP is measured at 6 units.

Due to its three vertices and three sections, a component is a polygon. It has a simple geometric form. Triangle ABC refers to a triangle only with points A, B, and C. When components are not collinear, a singular plane and triangle are found. Triangles are regarded as polygons since they have three corners and a right side. The points where a triangle's three sides intersect are known as the triangle's corners. By compounding three triangle angles, one gets 180 degrees.

Here,

Triangle OMN is provided.

Now, OMN and OPQ are comparable. It follows that the side lengths are in proportion to one another. We can write:

=>OP = OM = PQ = MN

=>OM = PQ/MN in 12

=>(OP + PM)/12 = PQ/MN

Considering that -

=>PQ = MP + 2

=>12/(OP plus PM) = (MP plus 2)/MN

=>12MN equals (MP + 2)(OP + PM).

=>12 × 12 = (MP + 2)(MP + 12)

=>2 MP plus 12 MP plus 2 MP plus 24 = 144

=>(MP)² + 14(MP) - 120 = 0

We can write - if MP = x.

=>x² + 14x - 120 = 0

=>(x + 20)(x - 6) = 0

=>(x + 20) = 0 and (x - 6) = 0

x = - 20 and x = 6

There can be no negative lengths, hence x = 6

Consequently, the length MP is measured at 6 units.

Therefore , the solution to the given problem of triangle comes out to be the length MP is measured at 6 units.

What is arithmetic?

In general, the term "arithmetic" (which comes from the Greek word "arithmos," "number") refers to the fundamental concepts of number theory, arts of mensuration (measurement), and numerical computation (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).

Given:

Jacqueline, Kimberly, and Julia collect mechanical pencils.

Kimberly owns two less than three times the number of mechanical pencils Jacqueline owns.

Julia owns three less mechanical pencils than Jacqueline.

Together, the three collectors own a total of 100 mechanical pencils.

We have to find the number of mechanical pencils Kimberly own.

Let the mechanical pencils of Jacqueline is x.

As Kimberly owns two less than three times the number of mechanical pencils Jacqueline owns.

⇒  The mechanical pencils of Kimberly are 3x - 2

As Julia owns three less mechanical pencils than Jacqueline.

⇒  The mechanical pencils of  Julia are x - 3

The three collectors own a total of 100 mechanical pencils.

⇒  x + (3x - 2) + (x - 3) = 100

                         5x - 5 = 100

                              5x = 105

                                x = 21

⇒ Mechanical pencils does Kimberly own are 3(21) - 2 = 63 - 2 = 61.

This system of equations has infinitely many solutions.

An equation is a mathematical statement that two expressions are equal. It can be written using numbers, symbols, and mathematical operations such as addition, subtraction, multiplication, and division. Equations can also be used to describe relationships between known values, like a line of best fit for data points. Equations are used in many areas of mathematics, such as geometry and calculus, to help solve problems or to describe physical phenomena.

This can be determined by looking at the coefficients of the variables. Since the coefficients of x in each equation are the same and the coefficients of y in each equation are different, this indicates that the equations are not equivalent and therefore, have infinitely many solutions.

Answer: To calculate the percentage decrease in the number of available seats, we can use the following formula:

(original value - new value) / original value * 100

In this case, the original value is 125 (the number of available seats before the reduction) and the new value is 93 (the number of available seats after the reduction). Plugging these values into the formula:

(125 - 93) / 125 * 100 = 32 / 125 * 100 = 0.256 * 100 = 25.6

So, there is a 25.6% decrease in the number of available seats.

The given expression is:

(23^20-53^19)/(-9)^9

This is a mathematical expression that involves multiple operations. The first step is to understand the order of operations, or PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction)

Parentheses: The expression does not contain any parentheses, so we can move on to the next step.

Exponents: The first term, 23^20, contains an exponent. The exponent operator (^) has higher precedence than the multiplication operator (), so we will simplify the exponent first. 3^20 is equal to 3 raised to the power of 20, which is equal to 3 * 3 * 3 * ... * 3 (20 times) = 59,049. Therefore, the first term is now 2 * 59,049.

The second term 5*3^19 also contains an exponent, so we simplify it in the same way as the first term. 3^19 is equal to 3 * 3 * 3 * ... * 3 (19 times) = 7,29,043. Therefore, the second term is now 5 * 7,29,043.

Multiplication and Division: After simplifying the exponents, we can see that the expression contains both multiplication and division. Since division has the same precedence as multiplication, we can simplify the expression from left to right.

The first term 2 * 59,049 is the product of 2 and 59,049. Multiplying these two numbers gives us 118,098.

The second term 5 * 7,29,043 is the product of 5 and 7,29,043. Multiplying these two numbers gives us 36,45,215.

The third term is the division of two terms. We have (23^20-53^19) / (-9)^9

Subtraction : Now we have the subtraction of two terms (118,098 - 36,45,215)

Now we have the division of two terms (-35,27,117) / (-9)^9. In this step, we are dividing the subtraction with -9 raised to the power of 9

The final step is to simplify the division. -9^9 is equal to -9 * -9 * -9 * -9 * -9 * -9 * -9 * -9 * -9 = -3486784401.

So the final expression is -35,27,117/-3486784401.

The expression is a very large negative number divided by a very large negative number, which results in a very small positive number.
