Given the data set:

23,17,14,21,23,18,29,20,13

a. 1. You need to order it from least to greatest:

13,14,17,18,20,21,23,23,29

2. You can identify the Range. Therefore, the minimum point of the whisker must be on:

13

And the maximum point on the whisker must be on:

29

3. Determine the Median of the whole data set (the middle value in the data set). Since there 9 values in the set, you can determine that:

Median=20

4. Find the Median of the bottom half part of the data:

Median_{bottom}=17

5. And the Median of the top half is:

Median_{top}=23

Knowing all that data, you can create the Box Plot:

b. By definition, the first quartile divides 25% of the data. Therefore, you can determine that the percentage of the data that is above the first quartile is:

75\text{\%}

c. By definition, the second quartile divides 50% of the data. Therefore, the percentage of the data that is below it is:

50\text{ \%}

Hence, the answers are:

a.

b.

75\text{\%}

c.

50\text{\%}

In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F
nevsk [136]
The third side of triangle ABC is AB. Using the Pythagorean Theorem, its length is 12. 
12² + 16² = 20² 

∠F is congruent to ∠C and so the sin(∠F) = sin(∠C) 

The sin(∠C) = opposite/hypotenuse 
= |AB| / |AC| 
= 12/20 
= 3/5 
= 0.6 

Answer: 
Yes, it is 0.6

The local radio tower is located 20 miles east and 12 miles north of Pamela's cabin. The radio tower has a 25 mile broadcast rad
pychu [463]

Answer:

x^2 +y^2 -40x -24y  -81 =0

Step-by-step explanation:

We can write the equation of a circle in the form

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

Assuming that Pamela's cabin is the center

( x-20)^2 + (y- 12)^2 = 25^2

We want to get to general form

x^2 + y^2 + Dx + Ey + F = 0,

Distributing

x^2 -40x +400 + y^2 -24y +144 = 625

x^2 +y^2 -40x -24y +544 -625 =0

x^2 +y^2 -40x -24y  -81 =0

I need help, I don’t need an explanation, just the answer
meriva

Answer:

x = 48 \:  \:  \:  \:  \:  \: y = 16

Step-by-step explanation:

y =  - x + 4y

y + x = 4y

y + x - 4y = 0

- 3y + x = 0

- x + 4y = 16

- 3y + x = 0

- 3y =  - x

y =  -  \frac{1}{3} ( - 1)x

y =  \frac{1}{3} x

4 \times ( \frac{1}{3} )x - x = 16

\frac{1}{3}x = 16

x = 48

y =  \frac{1}{3}  \times 48

y = 16

Hope this is correct and helpful

HAVE A GOOD DAY!
