By how much does the median of the data set 12, 9, 9, 11, 14, 28 change if the outlier is removed?

Answers

Hi there! Here's the answer and how I got that answer!!

Answer:

11

The change in the Median would be 11 instead of 11.5 because the total amount of numbers became odd when the outlier is removed. This allowed for the step of having to solve for two middle numbers to be avoided and therefore only leave you with the answer simple as 11 instead of having to solve between two numbers!

Step-by-step explanation:

With all the numbers (including the outlier) the median would be 11.5.

Here's how:

First sort least to greatest and cancel out the numbers until you get to the one on the middle.

9, 9, 11, 12, 14, 28

If you have two middle numbers add them together and then divide by two.

11+12=23

23/2= 11.5

So your median with the outlier is 11.5.

Now if you take out the outlier, which in this case I'm assuming its 28. Let's re-look for the median once more!

First sort least to greatest and cancel out the numbers until you get to the one on the middle.

9, 9, 11, 12, 14

Now because there is an odd amount of numbers your left to only one middle number, 11.

This means if the outlier is removed the median would change to be 11.

In the expression a = k/b, what is k

Answers

Answer:

k=ab

Step-by-step explanation:

a=k/b

a(b)=(k/b)(b)---multiple b to both sides to isolate k

k=ab

Answer:

k is the constant of variation.

Step-by-step explanation:

In direct variation:

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

In inverse variation:

[tex]y\propto \frac{1}{x}[/tex]

[tex]y=\frac{k}{x}[/tex]

[tex]yx=k[/tex]

In both cases k is the constant of variation

The given equation is

[tex]a=\frac{k}{b}[/tex]

We need to find the value of k in this equation.

First we have to isolate k on one side of the equation.

Multiply both sides by b to isolate k on right side.

[tex]a\times b=\frac{k}{b}\times b[/tex]

Cancel out the common factors.

[tex]ab=k[/tex]

Interchange the sides of the equation.

[tex]k=ab[/tex]

It means a and b are inversely proportional.

Therefore, the k is the constant of variation.

Step-by-step explanation:

cost of playing game = $1

winning if sum is odd = $10

winning if sum is 4 or 8 = $5

winning if sum is 2 or 12 = $50

two dice rolled, possible outcomes =

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

total no. of outcomes = 36

now according to the table of outcome with respect to winning money, we can calculate expected value by multiplying the probability of each roll with winning amount associated with each roll. and subtract the amount that we paid for the game that is $1.

E(x) = 1/36*($50) + 1/18*($10) + 1/12*($5) + 1/9*($10) + 5/36*($0) + 1/6*($10) + 5/36*($5) + 1/9*($10) + 1/12*($0) + 1/18*($10) + 1/36*($50)

= 25/18 + 5/9 + 5/12 + 10/9 + 0 + 5/3 + 25/36 + 10/9 + 0 + 5/9 + 25/18

Expected value = $8.89

Subtract the amount that was paid to play the game that is $1.

$8.89 - $1 = $7.89

A profit of $7.89 is expected every-time the game is played.

The perimeter of the triangle below is 4x + 3y. Find the measure of the missing side. (Picture of triangle)

Answers

Answer: 2x+3y

Step-by-step explanation: look at picture

Final answer:

To find the missing side in a triangle with a given perimeter, subtract the lengths of the known sides from the total frame. This is based on the sum of the lengths of all sides of a triangle, which equals its circumference.

Explanation:

We need to understand a simple rule about triangles to find the missing side of a triangle where the perimeter is 4x + 3y. The sum of all sides of a triangle equals its edge. So, if we know the length of the other two sides, we can subtract their sum from the total circumference to find the size of the missing side.

For example, if we know that the other two sides of the triangle are 2x and y, respectively, the missing side would be calculated by subtracting the sum of these sides from the given perimeter.

4x + 3y = perimeter
2x + y = known sides
missing side = (4x + 3y) - (2x + y)

Note: This method assumes that x and y values are provided. If they're unknown, we will require additional equations to solve for x and y before calculating the length of the missing side.

Answer:

4x+2y-5=0

Step-by-step explanation:

since you have to put the problem in that order you take 5 from both sides

Answer:

The correct answer is y = -2x + 5/2

Step-by-step explanation:

y = mx + b.  is the y intercept form of a line.

To find the  y = mx + b. form

It is given that,

4x + 2y = 5

2y = -4x + 5

Dividing both sides by 2 we get,

2y/2 = (-4x + 5)/2

y = -4x/2 + 5/2

y = -2x + 5/2

What are the solutions of the equation 3x^2+8x=12

Answers

x= -4/3 + 2/3 square root of 13 or x= -4/3 + -2/3 square root of 13 !!

Answer:

Step-by-step explanation:

3x² + 8x = 12

3x² + 8x - 12 = 0

a=3, b=8, and c=-12.  Solving with quadratic formula:

x = [ -b ± √(b² - 4ac) ] / 2a

x = [ -8 ± √(8² - 4(3)(-12)) ] / 2(3)

x = (-8 ± √208) / 6

x = (-8 ± 4√13) / 6

Amy has a triangle with side lengths of 6 and 8. What is the length of the
hypotenuse.

Answers

Hello There!

The length of the hypotenuse is 10.

We know what 2 sides are 6 and 8.

To find the third side we use the formula a^2 + b^2 = c^2

So we multiply 6 by 6 which equals 36 and then multiply 8 by 8 which equals 64.

Next we add 64 and 36 together and we get 100.

Next, we square root 100 and get 10.

10 is the length of the hypotenuse.

Generalize the pattern by finding an explicit formula for the nth term.

Answers

Answer:

an = 5 + 2n

Step-by-step explanation:

Each time it increases by the same amount (2), so this is an arithmetic sequence:

an = a₁ + d (n - 1)

Given a₁ = 7 and d = 2:

an = 7 + 2 (n - 1)

an = 7 + 2n - 2

an = 5 + 2n

Check our answer:

n=1: a₁ = 5 + 2(1) = 7

n=2: a₂ = 5 + 2(2) = 9

n=3: a₃ = 5 + 2(3) = 11

n=4: a₄ = 5 + 2(4) = 13

The pattern represents the arithmetic progression and the explicit formula for the nth term is a(n) = 2n + 5

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

According to the angle sum property of a triangles, the sum of interior angles of a triangle is 180°.

Apply angle sum property on triangle AEJ.

[tex]\angle A+\angle E+\angle J=180^{\circ}[/tex]

[tex]48^{\circ}+90^{\circ}+\angle J=180^{\circ}[/tex]

According to exterior angle property, the sum of two interior angles of a triangle is equal to the third exterior angle.

Apply exterior angle property on triangle JMS.

[tex]\angle EJA+\angle JSM=\angle EMS[/tex]

[tex]42^{\circ}+\angle JSM=59^{\circ}[/tex]

Subtract 42 from both sides.
