33 1/3 because it if you times it by 3, you get 100
D is the answer, 180 - 165 12' = 14 48'
Standard deviation would be the best measurement of variance. Most of the numbers are between 91 and 89 and are thus very close together and most of the data would be within that small range. The outlier of 60 makes the rance variance go from 60 to 91 when all but 6 percent of the class can be represented between 91 and 89.
Answer:
(E) 22,400
Step-by-step explanation:
Let b represent the amount invested in bonds. Then b/4 is the amount invested in stocks, and the total amount invested is ...
b/4 +b = 28000
5/4b = 28000 . . . . . collect terms
b = (4/5)(28000) = 22,400 . . . . . multiply by 4/5
22,400 is invested in bonds.
