A $80 television is on sale for $65. What percent discount was given? *

Answer:

B

Step-by-step explanation:

First, find the slope by using change in y divided by change in x.

Change in y = 5 - 2 = 3

Change in x = 2 - 1 = 1

This means that the slope is 3/1 = 3.

Then, you put it in the point-slope form so:

(y - 2) = 3(x - 1)

Answer: 3.7%

Step-by-step explanation:

Given:

The data set is 60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74.

To find:

The IQR and outliers.

Solution:

The given data set is

60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74

Arrange the data values in ascending order.

50, 54, 60, 62, 67, 70, 70, 74, 74, 82, 88, 89

Divide the data set in two equal parts.

(50, 54, 60, 62, 67, 70), (70, 74, 74, 82, 88, 89)

Divide each parentheses in two equal parts.

(50, 54, 60), (62, 67, 70), (70, 74, 74), (82, 88, 89)

Now,

[tex]Q_1=\dfrac{60+62}{2}[/tex]

[tex]Q_1=\dfrac{122}{2}[/tex]

[tex]Q_1=61[/tex]

And,

[tex]Q_3=\dfrac{74+82}{2}[/tex]

[tex]Q_3=\dfrac{156}{2}[/tex]

[tex]Q_3=78[/tex]

We know that, the inter quartile range is

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=78-61[/tex]

[tex]IQR=17[/tex]

The IQR is 17.

If the data values lie outside the interval [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex], then those values are known as outliers.

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[61-1.5(17),78+1.5(17)][/tex]

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[35.5,103.5][/tex]

All data values lie in the interval [35.5,103.5]. So, there are no outliers.

Therefore, the correct option is B.

Square Root of 72 in Simplest Radical Form

Simplest Radical Form

Here we answer "What is the square root of 72 (√72) in simplest radical form?" The square root of 72 in its simplest form means to get the number 72 inside the radical √ as low as possible.

Here is how to do that! First we write the square root of 72 like this:

√72

The largest perfect square of the factors of 72 is 36. We can therefore convert √72 like this:

√36 × 2

Next, we separate the numbers inside the √ as such:

√36 × √2

√36 is a perfect square that equals 6. We can therefore put 6 outside the radical and get the final answer to square root of 72 in simplest radical form as follows:

6√2

Answer:

The axis of symmetry is the horizontal shift. If I am not wrong, you might be learning about absolute value functions or parabolas.

The absolute value function: f(x)= a|x-h|+k

The parabola (Vertex form of a quadriceps function): f(x)= a(x-h)^2+k

The variable ‘h’ is the horizontal shift, in other words, the axis of symmetry

Answer:

Width=9.5, Length=32.5

Step-by-step explanation:

Let x be the width of the rectangle,

The length is 4 feet more than 3 times the width,

The length= 3x+4

The perimeter is

2(x)+2(3x+4)=84

2x+6x+8=84

8x=76

x=76/8

x=9.5

The Width=9.5

Length= 3(9.5)+4=32.5

The slope of the line that passes through the point (3, -10.5) and (7.-28.5) will be -5

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

The slope of the line is calculated as follows:

m = Δy/Δx

Given that the line that passes through the points (3, -10.5) and (7.-28.5)

To find the slope of the line that passes through points (3, -10.5) and (7.-28.5).

Therefore, the slope of the line is;

m = Δy/Δx

m = (-28.5- 10.5)/(7 - 3)

m = -20/4

When we simplify it, then we get;

m = -5

Hence, the slope of the line is -5.

Step-by-step explanation:

Since your going from 18 to 45, your increase of percentage would be 150%, and the difference is 27.

Answer:

The equation would be 8n + 11 = 3n + 26.

Answer:

I'm gonna assume we're talking about  "n".

b) 8n+11=3n+26 (because they are corresponding angles)

n=3

Step-by-step explanation:

8n+11=3n+26    

simplifying:

8n-3n+11-11=3n-3n+26-11
