Here, we are required to determine how far the student described in the question is from the average.
The correct answer is Choice C: |x – 78|.
According to the question; the student received a score of x%.
As such, x% may either be greater or lesser than the average score, 78%.
- <em>To determine how far the student's score is from the average, we need to take the difference between the student's score and the average score; i.e. (x - 78)</em>
- <em>This difference may however be negative: As such, there's need to take the absolute value of (x - 78) which yields |x – 78|.</em>
<em>Therefore, the expression that could be used to determine how far the student’s score is from the average is; |x – 78|</em>

Answer:
Hey there!
The measure of angle ABD plus the measure of angle CBD equals 90 degrees or a right angle.
Thus, we can write the equation: ABD+51=90
Solving for ABD, we find that it is 39 degrees.

Step-by-step explanation:
3. The tree increased in height each month until the time period between month 9 and month 11.
Step-by-step explanation:
We have been given a table that shows the height of the tree that Margo planted over an 11-month period.
Let us see which of the given statement can be supported by the information in the table.
1. The tree increased in height each month during the entire 11-month period.
We can see from our table of data that Margo's tree increased till 9 months and its height decreased between 9 to 11 months from 3 feet to 1.8 feet, therefore, first statement is not true.
2. The tree decreased in height each month during the entire 11-month period.
We can see from our table that height of Margo's tree increased till 9 months from 1.4 feet to 3 feet and its height decreased between 9 to 11 months from 3 feet to 1.8 feet, therefore, second statement is not true.
3. The tree increased in height each month until the time period between month 9 and month 11.
We can see that height of tree increased for 9 months (1.4 ft to 3 ft) and between 9 to 11 months height decreased (3 ft to 1.8 ft), therefore, our 3rd statement is true and the information given in the table is supporting this statement.
4. The tree decreased in height each month until the time period between month 9 and month 11.
We have seen that the tree increased in height each month until the time period between month 9 and month 11, therefore, our 4th statement is not true.
