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{\%}

Find (fog)(x). f(x) = 2x
Blababa [14]

Answer: (f•g)(x)=​2x²+12x

Step-by-step explanation:

(f•g)(x) is the same as saying f(x)•g(x). Since we have f(x) and g(x), we can just multiply them together.

(f•g)(x)=​2x(x+6)                [distribute by FOIL]

(f•g)(x)=​2x²+12x              

Now, we know that (f•g)(x)=​2x²+12x.

In 1990 the average family income was about $ 39 , 000 , and in 2010 it was about $ 70 , 768 . Let x = 0 represent 1990, x = 1 r
iren2701 [21]

Answer:

<em />f(x) = 1588.4x + 39000<em />

f(15) = 62826

Step-by-step explanation:

Given

In 1990; Income= $39000

In 2010; Income= $70768

Solving (a): An equation in form of f(x) = ax + b

First, we need to determine the slope, a

a = \frac{y_2 - y_1}{x_2 - x_1}

Taking y as income and x as year index.

When x = 0; y = 39000

When x = 20; y = 70768

Substitute these values in the above formula

a = \frac{70768 - 39000}{20 - 0}

a = \frac{31768}{20}

a = 1588.4

Next, is to determine the formula using:

y - y_1 = a(x - x_1)

<em>Considering :When x = 0; y = 39000, we have</em>

<em />y - 39000 = 1588.4(x - 0)<em />

<em />y - 39000 = 1588.4x<em />

<em>Make y the subject of formula</em>

<em />y = 1588.4x + 39000<em />

<em />

<em>Express y as a function of x</em>

<em />f(x) = 1588.4x + 39000<em />

Solving (b): Income in 2005

<em>In 2005, x = 15</em>

So:

f(x) = 1588.4x + 39000 becomes

f(15) = 1588.4 * 15 + 39000

f(15) = 62826
