The median of a set of numbers is the middle number in the set (after the numbers have been arranged from least to greatest) -- or, if there are an even number of data, the median is the average of the middle two numbers.

For example:

Find the median of the set {2,5,8,11,16,21,30} .

There are 7 numbers in the set, and they are arranged in ascending order.  The middle number (the 4 th one in the list) is 11.  So, the median is 11.

The center of a data set is also a way of describing the location. The two most widely used measures of the center of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50. To find the median weight of the 50 people, order the data, and find the number that splits the data into two equal parts. The median is generally a better measure of the center when there are extreme values or outliers because it is not affected by the precise numerical values of the outliers.

(-4, 2)

This point lies on the second quadrant because this point has negative x-axis value and positive y-axis value

(-1, 0)

This point also lies on the x-axis because the y-axis value is zero.

(-4, -6)

This point also lies on the third quadrant because this point has negative x-axis and y-axis values

On the cartesian plane, four regions are created at the point where the X and Y axes intersect at 90 degrees. These regions are known as quadrants. Each of the four quadrants in each plane is therefore bound by one-half of the axes. Depending on where they are in relation to the axes, each quadrant is identified by a Roman numeral and given the names Quadrant I, Quadrant II, Quadrant III, and Quadrant IV.

Answer:

I don't think this is possible to solve,

Step-by-step explanation:

We get the reflection of points T, U and V as T' = (0, 2), U' = (0, 1) and V' = (0, 4) over the x- axis.

We are given some coordinates:

T(0, - 2), U(2, - 1), V(3, - 4)

We have to first plot them on a graph.

Now, we have to reflect them over x - axis.

To reflect over x- axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.

For point T:

Additive inverse of - 2 = 2

T' = (0, 2)

For point U:

Additive inverse of - 1 = 1

U' = (0, 1)

For point V:

Additive inverse of - 4 = 4

V' = (0, 4)

Therefore, we get the reflection of points T, U and V as T' = (0, 2), U' = (0, 1) and V' = (0, 4) over the x- axis.

The equation to represent the relationship between Distance and Time will be 52y = x, where Speed remains constant

In the given question, it is said that the train runs along a distance of 156 miles, which takes 3 hours to complete.

The equation that represents the relationship between Speed, Distance, and Time is as follows :

=> Speed = Distance/Time

It is also stated that the train runs at the same speed so the Speed will be constant while deriving the relationship between Distance and Time.

First, we have to find the speed of the train with the given Distance & Time by the formula => S = D/T, where Speed = S, Distance = 156 miles, and Time = 3 Hours

=> S = 156/3 => S = 52 miles/hour

As we got our constant speed for the train, We can now find out the Distance Time relation of the train. By taking Distance = x, Time = y, Speed = 52 miles/hour

                     => 52 = x/y      => 52y = x

Hence, we get the relationship between Distance and Time where Speed is constant at 52 miles/hour

The vertical height of the rocket at the end of the third stage is 83.2 km.

We are provided that the rocket travels first 10 km vertically up (OA), then the rocket travels for 20 km (AC) at an angle of  15° from point A.

Let rocket travels 'a' distance vertically up(AB) during this,

then, rocket travels for travels for 60 km (CD) at an angle of  26° from point C.

Let rocket travels ' b' distance vertically up (BX) during this.

So,

Total Vertical Height Covered = 10 + a + b

So, According to diagram

In ΔABC

[tex]cos \ 15[/tex]° [tex]= \frac{a}{20}[/tex]

[tex]\\a = 20 * cos 15[/tex]° = 19.32km

In ΔCDE

[tex]cos \ 26[/tex]° [tex]= \frac{b}{60}[/tex]

[tex]\\b = 60 * cos 26[/tex]° = 53.9km

Since,

Total Distance = 10 + a +b

Total Distance = 10 + 19.32 + 53.9

Total Distance = 83.2 km

Therefore, Vertical height of the rocket at the end of third stage =  83.2 km

The simplified equation of the given statement = 1.08r.

Even though they also have different operations, adding and subtracting variables follow the same rule: while adding or subtracting terms with the same variables, either add or subtract the coefficients and leave the result with the variable. As an example, consider an addition.

The original cost of the new robotic toy is given as r.

The cost of the new robotic toy after a 8% markup is: c + 0.08r to show that 8% of r was being added to r to increase the price.

Because both numbers in the equation are related to the same variable, they can be added. When r is used alone, it is considered to be 1r.

The slope intercept form of a line which passes through the points (-2, 5) and (6, -4)  is  y = (-9/8)x + 11/4.

According to the question.

A line passes through the two points (-2, 5) and (6, -4).

As we know that, the slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.

So, the slope of the line = -4 -5/(6 + 2) = -9/8

And, the slope intercept form of a line which passes through the points (-2, 5) and (6, -4) is given by

y = (-9/8)x + b

Since, the line passes through (-2, 5) and (6, -4). So, both the points must statisfy the above equation.

⇒ 5 = (-9/8)(-2) + b

⇒ 5 = 9/4 + b

⇒ b = 5 - 9/4

⇒ b = (20 - 9)/4

⇒ b = 11/4

Therefore, the slope intercept form of a line which passes through the points (-2, 5) and (6, -4)  is  y = (-9/8)x + 11/4.

The perimeter of the triangle formed by the points B(7,-9), C(7,-2) and D(0,0) is 25.68 square units.

Perimeter is defined as the distance or the enclosed path that surrounds the 2-D shapes or polygon. The perimeter of a triangle is the sum of all the three sides of a triangle.

The perimeter of a triangle formed by the points B(7,-9), C(7,-2) and D(0,0) can be determined by finding the distance between two points.

The distance between two points A(x1,y1) and B(x2,y2).

√[(x2-x1)²+(y2-y1)²]

Therefore, BC = √(7-7)²+(-2+9)²

BC = √49

BC = 7 square units.

and CD = √(0-7)²+(0+2)²

CD = √53

CD = 7.28 square units.

and DB = √(7-0)²+(-9-0)²

DB = √130

DB = 11.40 square units.

Therefore, perimeter of triangle formed from given points is BC+CD+DB =  7+7.28+11.40 = 25.68 square units.
