In the given question, there are several information's of immense importance. using these information's the correct and the required answer can be determined. It is given that an unknown number has to be found from the information's provided.
Let us assume the unknown number = x
Then
3x + 3 = 2x -1
3x - 2x = -1 -3
x = -4
So the unknown number is -4.
It should be remembered that these are trick questions and it is important to go through each lines very carefully to understand the inner meaning.
you find what number goes into both number and pull that number outside and then write. 3 (_x+_). you are reversing the distributive property. Hope this helped
Considering the given box-and-whisker plot, it is found that the bookstore sold between 2 to 12 books in 20 days.
<h3>What does a box-and-whisker plot shows?</h3>
A box and whisker plot shows three things:
- The 25th percentile, which is the median of the bottom 50%.
- The median, which splits the entire data-set into two halfs, the bottom 50% and the upper 50%.
- The 75th percentile, which is the median of the upper 50%.
From the plot given in this problem, the have that:
- The 25th percentile is of 2.
- The 75th percentile is of 12.
This means that the percentage of days in which between 2 to 12 books were sold is:
P = 75 - 25 = 50%.
Hence, out of 40 days, the amount of days is:
0.5 x 40 = 20 days.
