Answer:

\frac{9}{16}

Step-by-step explanation:

Let total number of students=x

Students went to the book fair:

Students went to book fair=\frac{15}{20}\times total\ number\ of\ students=\frac{15}{20}x

Students who bought book:

Students\ who\ bought\ book=\frac{12}{16}\times Number\ of\ students\ went\ to\ book\ fair=\frac{12}{16}\times \frac{15}{20}x=\frac{9}{16}x

Hence \frac{9}{16} of total students bought at least one book.

The descriptive statistics are shown.

The median is always at the center of the box, we can say the median of our question is also at the middle of the box.

<h3>What is a graph?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The description of the measures given has been done below and also what they indicate about the shape of the box and whisker plot have been given.

From the given data we see that;

Mean = 39,500

Median = 20000

Mode = 23000

Minimum = 15,000

Maximum = 255000

A general view of a box and whisker plot has been attached.

From the attached file, we can see the following;

- whiskers to the left and right of the box.

- The box starts from the lower quartile and stops at the upper quartile.

- The median is at the middle of the box

- The minimum is at the end of the left whisker

- The maximum is at the end of the right whisker.

1) Now, since median is always at the center of the box, we can say the median of our question is also at the middle of the box.

2) The median is 20000 but the minimum which is the end of the left whisker is 15000 while the maximum which is the end of the right whisker is 255000. This means the minimum is very close to the median and as such the left whisker would be very short. In contrast, the right whisker will be very long since the maximum is far larger than the median.

3) Since the right whisker is far larger than the left whisker, then we can say the shape of the box and whisker plot is heavily skewed to the right.

Find the solution set of this inequality. select the correct graph. |-4x+14|&gt;6
lions [1.4K]
Split the inequality into two:
(-4x+14)>6 & -(-4x+14)>6

solve:
(-4x+14)>6
-4x>-8
x<2
(symbol changes when ÷/× by negative for inequalities.)

-(-4x+14)>6
-4x+14<-6
-4x<-20
x>5

the answers are x<2 and x>5, so you would write your answer like this: (-∞,2) ∪ (5,∞)
