Step-by-step explanation:

This system of equations has been placed in a matrix:

y = 650x + 175

y = 25,080 - 120x

The option is ( 32.34, 21,196)

A system of equations, also called a set of simultaneous equations or a system of equations in mathematics, is a finite set of equations for which we have found a general solution. Systems of equations can be classified in the same way as individual equations. Systems of equations are applied in our daily life in modeling problems where unknown quantities can be expressed as variables.

Solving a system of equations means finding the values ​​of the variables used in the system. Calculates the value of an unknown variable while balancing both equations. The main reason for solving a system of equations is to find the values ​​of the variables that satisfy the conditions of all given equations. This system of equations can have different types of solutions.

1. unique solution

2. no solution

3. infinite set of solutions

Now,

We can solve the given system by making the equations equal because

y = y .

The equations are y = 650x + 175 and y= 25,080 - 120x, which forms

   650x + 175 = 25,080 - 120x

⇒ 650x +120x = 25080- 175

⇒ 770x = 24905

⇒ x = 24905 / 770

⇒ x = 32.344

≈ 32.34

Using this value, we find the other one.

   y = 650x + 175

⇒ y = 650 × 32.34 + 175

⇒ y = 21021 + 175

⇒ y = 21196

Therefore, the solution of the system is (32.34 , 21,196).

Step-by-step explanation:

The mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)

Given data values are 55, 56, 70, 61, 53, 57, 50, 73, 52, 69, and 2. We need to calculate the mean, median, and mode of this sample.So, let's first arrange the data values in ascending order:2, 50, 52, 53, 55, 56, 57, 61, 69, 70, 73

Mean:The mean is the sum of all the data values divided by the total number of data values. So, we can use the following formula to calculate the mean:

Mean = (sum of all the data values) / (total number of data values)Sum of all the data values = 55 + 56 + 70 + 61 + 53 + 57 + 50 + 73 + 52 + 69 + 2 = 598Total number of data values = 11

Therefore,Mean = (sum of all the data values) / (total number of data values) = 598 / 11 = 54.36 (rounded to two decimal places)Therefore, the mean of the given data values is 54.36.

Median:The median is the middle value of a sorted data set. Since the data set has 11 data values, the median is the average of the 6th and 7th values (counting from smallest to largest).

Therefore, the median is :Median = (55 + 56) / 2 = 55.5Therefore, the median of the given data values is 55.5.

Mode:The mode is the data value that appears most frequently in the data set. In this case, there is no data value that appears more than once. So, there is no mode.

Therefore, the mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)

How is this math?

Answer:

its none

Step-by-step explanation:

The dimensions of the rectangle are 3 inches by 5 inches.

Let x be the length of one side of the rectangle. Then the other side is 2 inches longer, so its length is x + 2. The area of the rectangle is given by A = L × W, where L is the length and W is the width.

We are told that the area of the rectangle is 15 square inches, so we can set up the equation:

x(x + 2) = 15

Expanding the left side, we get:

x^2 + 2x = 15

Subtracting 15 from both sides, we get:

x^2 + 2x - 15 = 0

We can factor the left side of the equation to get:

(x + 5)(x - 3) = 0

Therefore, either x + 5 = 0 or x - 3 = 0. Solving for x in each case, we get:

x = -5 or x = 3

Since the length of a side cannot be negative, we must reject the solution x = -5. Therefore, the length of one side of the rectangle is x = 3 inches. The other side is 2 inches longer, so its length is x + 2 = 5 inches. Therefore, the dimensions of the rectangle are 3 inches by 5 inches.

The Slope from the given points is 3

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are perpendicular, parallel, or none at all.  

Here we have

On a coordinate plane, a line goes through (0, 8) and (2, 2).

As we know Slope of a parallel line is (y₂-y₁)/(x₂-x₁)

Take (x₁, y₁) = (0, 8) and (x₂, y₂) = (2, 2)

Slope of line = [ 2 - 8]/[0 - 2 ] =  [ - 6]/[ - 2 ] = 3

Answer:

B. 642.22 units squared

Step-by-step explanation:

Knowing that QP ║ MN and ∠QLP = ∠MLN, then ΔQLP ~ ΔMLN.

That means corresponding sides and heights have the same ratios.

We know that QP = 25, which corresponds to MN = 34. Also, the height of ΔQLP, LS, corresponds to the height of ΔMLN, LR = LS + SR = LS + 10. Let's say LS = x.

We can now write:

QP / MN = LS / LR

25 / 34 = x / (x + 10)

Cross-multiply:

34 * x = 25 * (x + 10)

34x = 25x + 250

34x - 25x = 250

9x = 250

x = 250/9 ≈ 27.78 units

So, LS = 27.78 units and LR = LS + SR = 27.78 + 10 = 37.78 units.

The area of a triangle is denoted by A = (1/2) * b * h, where b is the base and h is the height.

Here, the base of ΔLMN is MN = 34, and the height is LR = 37.78. Plug these in:

A = (1/2) * b * h

A = (1/2) * 34 * 37.78 ≈ 642.22 units squared

The answer is thus B.

The requreid equation of the circle is  x² + y² = 16.

Since each right triangle inside the circle has a hypotenuse of 8, then the radius of the circle is also 8.

The equation of a circle with center (h, k) and radius r is given by:

(x - h)² + (y - k)² = r²

In this case, the center of the circle is (0, 0) and the radius is 8, so the equation of the circle is:

x² + y² = 16

Thus, the requreid equation of the circle is  x² + y² = 16.

Answer:

Step-by-step explanation:

Answer:

Assuming that the expression is meant to be written as:

(a^5 ⋅ 2^3)^3

We can simplify it using the rules of exponents. First, we can simplify the expression inside the parentheses:

a^5 ⋅ 2^3 = a^5 ⋅ 8 = 8a^5

Now we can substitute this simplified expression into the original expression:

(8a^5)^3

To simplify this, we use the power rule of exponents, which states that when we raise a power to another power, we multiply the exponents:

(8a^5)^3 = 8^3 ⋅ (a^5)^3 = 512a^15

Therefore, the simplified expression is 512a^15.

CBS's share of households in the city is 8%.

Out of the 1000 households in the city:

100 are watching ABC

80 are watching CBS

50 are watching NBC

70 are watching Fox

500 are watching everything else

200 do not have the TV set on

To calculate CBS's share, we need to find the percentage of households that are watching CBS out of the total number of households:

CBS's share = (number of households watching CBS / total number of households) x 100%

CBS's share = (80 / 1000) x 100%

CBS's share = 8%

Therefore, CBS's share of households in the city is 8%.
