To figure this out you can do 7.2/8.2, because you are trying to figure out how much of the total was used, and percentages would not be more than 100%. Doing this you would get ~.878. To convert this to a percent, you would just multiply it by 100, which would give you 87.8%. The question states to round to the nearest whole percent, leaving you with 88%. This means that 88% of the revenue was spent.
Hope that helped, don't be shy to comment on this if you have any questions about my explanation :)
Answer:
3/4
Step-by-step explanation:
1/2=2/4
2/4+1/4=3/4
Note that A and D are ludicrous choices, so you can throw them away outright. (Any divergent series cannot have a sum, and any convergent series must have a sum.)
The sum is certainly convergent because it can be written as a geometric sum with common ratio between terms that is less than 1 in absolute value.


We can then find the exact value of the sum:




So the answer is B.
Answer is 6/5
Step by step exploration
4/5 : 2/3 = 4/5 • 3/2= 12/10=6/5
I think it’s standard deviation.
