Step-by-step explanation:

Answer:

z(max) = 16

z(min) = -24

Step-by-step explanation:

2x - y = 12 multiply by 2

4x - 2y = 24 (1)

4x + 2y = 0 add equations

8x = 24

x = 3

4(3) + 2y = 0

y = -6

so (3, -6) is a common point on these two lines

z = 2(3) + 5(-6) = -24

4x - 2y = 24 (1)

x + 2y = 6 add equations

5x = 30

x = 6

6 + 2y = 6

y = 0

so (6, 0) is a common point on these two lines

z = 2(6) + 5(0) = 12

4x + 2y = 0 multiply by -1

-4x - 2y = 0

x + 2y = 6 add equations

-3x = 6

x = -2

-2 + 2y = 6

y = 4

so (-2, 4) is a common point on these two lines

z = 2(-2) + 5(4) = 16

The missing value for the probability distribution can be completed by option A.

What is probability distribution?

A probability distribution is a mathematical function that calculates the likelihood that various possible outcomes of an experiment will occur.

Main body:

We know that the sum of probability distribution is always 1.

P= P(X=1) + P(X=2) + P(X=4) + P(X=8) + P(X=16) + P(X=32) + P(X=64)

1= 0.1 + 0.05 + 0.25 + 0.25 + 0.05 + P(X=32) + P(X=64)

P(X=32) +P(X=64) = 1-0.7

                             = 0.3

This condition is satisfied by option A.

hence the answer is option A.

Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable. If the linear equation has two variables, then it is called linear equations in two variables and so on. Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.

The value of x  when the average (arithmetic mean) of the five numbers x, 7, 2, 16, and 11 is equal to the median of the five numbers is 9 (Nine).

Median :  In data sets having an odd or even number of values, find the median. The median is the value that divides a data sample, a population, or a probability distribution's upper and lower halves in statistics and probability theory. It could be referred to as "the middle" value for a data set.

Arithmetic mean : The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.

Five numbers are x, 7, 2, 16, and 11—are provided.

Average = sum/5 = (x+36)/5

Median = (x+36)/5

In given rectangle , value of x=8 and y=11.

What is rectangle?

   An example of a quadrilateral with equal and parallel opposite sides is a rectangle. It is a polygon with four sides and four angles that are each 90 degrees. An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. a flat, four-sided shape having straight sides and right-angled internal angles. Additionally, the opposing sides are parallel and the same length.

Here let us take rectangle as ABCD.

Here the given rectangle angle of B is 90°.

We know that angles in each side of rectangle is 90°.

Here ∠C=36°+c

=> 90=36+c

=> c=90-36 = 54°.

Here consider the triangle ABC , sum of all angles in triangle is 180°.

=>4x+4+90+54=180

=>4x+148=180

=> 4x=32

=> x=32/4 = 8.

Now angle A is sum of 4x+4 and 4y+10 is 90°.

=> 4x+4+4y+10=90

=>32+4+10+4y=90

=>46+4y=90

Step-by-step explanation:

Definitions:

To determine if the relationship is linear, calculate the rate of change between the ordered pairs given in the table:

[tex]\implies \sf rate\;of\;change=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{13.50-6.75}{6-3}=\dfrac{6.75}{3}=2.25[/tex]

[tex]\implies \sf rate\;of\;change=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{6.75-2.25}{3-1}=\dfrac{4.5}{2}=2.25[/tex]

As the rate of change is the same, the relationship is linear.

[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Point-slope form of a linear equation}\\\\$y-y_1=m(x-x_1)$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $(x_1,y_1)$ is a point on the line.\\\end{minipage}}[/tex]

The rate of change is the slope of a linear equation.

Therefore, to create an equation, substitute the found slope (2.25) and one of the ordered pairs (1, 2.25) into the formula:

[tex]\implies y-2.25=2.25(x-1)[/tex]

[tex]\implies y-2.25=2.25x-2.25[/tex]

[tex]\implies y=2.25x[/tex]

Therefore, the output is 2.25 times the input.

If the input is x, then the output is 2.25x.

If the input is 12, then the output is 2.25 × 12 = 27.
