I think its the Associative property
You do 28-12 to find out how much girls there are then you get 16 and you have the ratio of 12/16 then divide by 4. Then you get 3/4 boys to girls
2/3 = 0.66
1 hour = 60
60 x 0.66 = 39.6 or 40
60 - 40 = 20
He would drink 3 1/2 liters every 30 minutes.
He drinks 3 1/2 every hour.
Answer:
Mean Absolute Deviation (MAD): 8.5
Step-by-step explanation:
Xmean = (28 + 32 + 47 + 16 + 40 + 35 + 38 + 54)/8 = 290/8
Xmean = 36.25
MAD =
(28 - 36.25) + (32 - 36.25) + (47 - 36.25) + (16 - 36.25) + (40 - 36.25) + (35 - 36.25) + (38 - 36.25) + (54 - 36.25) divided by 8
a break down of each ( )
(8.25) + (4.25) + (10.75) + (20.25) + (3.75) + (1.25) + (1.75) + (17.75) divided by 8 = 68
then you take 68/8 = Mean Absolute Deviation 8.5
Answer:
8 UNITS
Step-by-step explanation:
12/8 = k/6
4/3 = k/6
24 = 3k
k = 8
