It would be mean. The mean is the average that is you are looking for, since she wants a summerization of all the values in the data set. To find the mean (average) add all the numbers and then divide by the amount of numbers.
Step-by-step explanation:
The amount of time from 10pm to 7am is 9 hours. However, the time indicated is 7:10am. Since there are 60 minutes in an hour, 10 min is equal to 1/6 of an hour. Therefore, the total time that the water level of the pool decreased is 
hours or 
hours. To find the rate at which the water level decreased, we divide the change in the water (in inches) by the time it took to reach that level. So we write
rate of change 
The area of the parallelogram is 1.2 m²
Answer:

Pulling out like terms
5.1 Pull out like factors :
12x4 + 16x3 - 7x2 - 6x =
x • (12x3 + 16x2 - 7x - 6)
Checking for a perfect cube :
5.2 12x3 + 16x2 - 7x - 6 is not a perfect cube
Answer: Solve this problem using the angle bisector theorem. This theorem states that when given a triangle with an angle bisector (line that cuts one of the angles in half, into two of the same angles), that angle bisector divides the opposite side into two segment proportional to the sides of the triangle
