Answer:
2
Step-by-step explanation:
|a+x|/2-|a-x|/2
Plug in the values.
|-2+-6|/2-|-2- -6|/2
Evaluate.
|-8|/2-|4|/2
Apply rule : |-a| = a
8/2 - 4/2
4 - 2
Subtract.
= 2
2n + 32 = 4n - 2
-2n = - 34
n = 17

Answer:
See explanation.
Step-by-step explanation:
<u>Aim of experiment:</u>
To discover the amount of time (average amount of time) that 7th grade students spend on homework each week.
<u>Name of researcher:</u>
Mary.
<u>Requirements for the experiment:</u>
- knowledge of the number of hours that some or all of the students spend on homework each week
- knowledge of the total number of 7th grade students (population statistics)
<u>The issue or problem with this question </u>is that it doesn't say what Mary found out after her research. There are no result statistics from the experiment! Mary surveyed 20 students out of the 164. Her findings will/can be used to infer about the population. Those findings are absent here, hence the question can't be solved.

Combining three equal groups means that we will mainly depend on multiplying the quantity by 3 to get the total
<u><em>Examples are shown below:</em></u>
1- Mrs Nadia teaches three classes. Each class has 25 student. How many students does Mrs Nadia teach in total?
<u>In this problem</u> we will be combining three equal groups of students where each group has 25 students, therefore:
Total number of students = 3 * 25 = 75 students
2- John has three bags of candies. Each bag contains 10 pieces of candies. How many candies does John has?
<u>In this problem</u> we will be combining three equal groups of candies where each group has 10 pieces, therefore:
Total number of candies = 3 * 10 = 30 candies
Hope this helps :)
