Answer:
Step-by-step explanation:
Given : Emerson has $120
Each week, he saves an additional $15.
To Find: Write a function f(x) that models the total amount of money Emerson has after x weeks.
Solution:
He saves in 1 week = $15
He saves in x weeks = $15x
He already has $120
So, total amount of money = 120+12x
So, Function:
Hence a function f(x) that models the total amount of money Emerson has after x weeks is .

Answer:
Any set of data that satisfies the 5-Number summary: 1,6,12,16 and 19 can be represented with the box plot.
Step-by-step explanation:
<u>Interpreting Box Plots</u>
A box plot is used to present the 5-Number summary of a set of data.
The 5-Number summary consists of the following in their order of appearance on the box plot.
- Minimum Value
- First Quartile,
- Median,
- Third Quartile,
- Maximum Value
In the box plot, the following rules applies
- The whisker starts from the minimum value and ends at the first quartile.
- The box starts at the first quartile and ends at the third quartile. There is a vertical line inside the box which shows the median.
- The end whisker starts at the third quartile and ends at the maximum value.
Using these, we interpret the given box plot
A left whisker extends from 1 to 6.
- Minimum Value=1
- First Quartile =6
The box extends from 6 to 16 and is divided into 2 parts by a vertical line segment at 12.
- Median=12
- Thrid Quartile=16
The right whisker extends from 16 to 19.
- Maximum Value =19
Therefore any set of data that satisfies the 5-Number summary: 1,6,12,16 and 19 can be represented with the box plot.
