Answer:
(800 x 9) + (10 x 9)
Step-by-step explanation:
Find out what 810 x 9 is:
810 x 9 = 7290
Then see which expression has the same answer. Personally I'd check all of them, but luckily the first expression is the correct one so you don't need to go through the rest (since it only asks for one correct expression):
(800 x 9) = 7200
(10 x 9) = 90
7200 + 90 = 7290
Answer:
Divide the each part and get the circle 360 and triangle 180
The teacher made progress in standardizing the test scores from the beginning of the year to the end. The MAD tells us this because the difference in the teachers scores from the mean is less at the end. The Mean Absolute Deviation is a measure of variability, and the smaller the number, the less variability there is in the answers. So, in this example there are more scores closer to the average than when they first graded the essays.
