You can replace u with -3 since u = -3. You should get something like this: -3 - 4(-3) + 3. This can be turned into -3 + 12 + 3, and subtracting negative numbers are the same as adding the positive version. -3 plus 12 is 9, and 9 plus 3 is 12. The final answer is 12. Hope this helps!
We are given a set of data depicting the number of books read by students.
We are required to find the mode of the data.
In order to find the mode, we simply need to count each unique number and know how many times each number occurs.
The unique number with the largest frequency of occurence is the mode of the data.
The data given is:

We will represent each count for the unique numbers with a frequency table showing each unique number and the number of times it occurs.
This table is done below:

This is because



(that is, replace any instance of <em>x</em> in the definition of <em>g</em> with √<em>x</em> )
and


(replace any <em>x</em> in <em>f</em> with √<em>x</em> - 1)
Also acceptable:


(assuming <em>x</em> is not negative)
Answer:
4, 11
Step-by-step explanation:
Q# 13 :
Let the first number be 'x'
the 2nd number would be ' x + 7'
x + x + 7 = 15
2x= 15-7
x= 8/2
x= 4
2nd number: x + 7
= 4+7
= 11
The median in the box plot is: 31
Q1 (lower quartile) = 26
<h3>What is the Median and Q1 of a a Data in a Box Plot?</h3>
The median is the value at the vertical line that divides the box.
The Q1 (lower quartile) is the value at the beginning of the edge of the box.
Thus, from the given box plot, we have the following:
Median = 31
Q1 (lower quartile) = 26
