Answer:
Given that the maximum age of the textbook is 7.9 years and the minimum age of the textbook is 1.3 years.
Using the range rule, the standard deviation is estimated as,
S≈maximum−minimum/4
=7.9−1.3/4
=1.65
The required value of the approximate standard deviation is 1.65.
To identify which data set is represnted by the box plot, find the data set that has the exact five-nunber summary of the box plot given.
<h3>What is a Box Plot?</h3>
If you identify the five-number summary of a data set, you can easily draw a box plot, because the values of each of the five-number summary is exactly what you are going to see on a box plot.
The min, max, lower and upper quartile, and median, which are the five-numnber summary of a data set is displayed as shown in the box plot attached below.
Therefore, to identify which data set is represnted by the box plot, find the data set that has the exact five-nunber summary of the box plot given.

Answer:
Part A) The zero's of the function are 
Part B) The solution set is the interval ![[0.84,7.16]](https://tex.z-dn.net/?f=%5B0.84%2C7.16%5D)
Step-by-step explanation:
we have

Using a graphing calculator
Part A) What are the zeros of the inequality to the nearest hundredth?
The zero's of the function are the values of x when the values of the function are equal to zero
see the attached figure
The zero's of the function are

Part B) What is the solution set for the inequality?
The solution set is the interval ![[0.84,7.16]](https://tex.z-dn.net/?f=%5B0.84%2C7.16%5D)
All real numbers greater than or equal to 0.84 and less than or equal to 7.16

2x − 3 < x + 2
∴ x − 3 < 2
∴ x < 5
x + 2 ≤ 3x + 5
∴ 2 ≤ 2x + 5
∴ -3 ≤ 2x
∴ -3/2 ≤ x
<span>-3/2 ≤ x < 5</span>
