8 x 64
=64 x 2 x 4
=128 x 2 x 2
=256 x 2
=512
1 quarter = 25 cents (he has 2 therefore its 50 cents)
10 dimes = 100 cents = 1 dollar
Oliver has twice as many dimes than he does quarters because 100 divided by 50 = 2. Hope this helps!
Answer:
A
Step-by-step explanation:
All pieces of data for seventh grade classes are larger than that of any kindergarten class on the table. This also proves with the mean provided.
The MAD, mean absolute deviation, helps you to identify the variation. The MAD for seventh grade was significantly larger than that of the kinder classes. The range for both sets of data is two times one another, further proving that 7th grade classes varies more.
C and D are irrelevant, and B says "varies less" which is the opposite of what's going on.
Hope that helps!
