The first term is a = 72
The common ratio is r = 1/6.
We multiply each term by 1/6, which is the same as dividing each term by 6.
To find r, divide any term you want over the previous term
r = 12/72 = 1/6
r = 2/12 = 1/6
etc.
Now use the infinite sum formula to find S
S = infinite sum
S = a/(1-r) ... see note below
S = 72/(1-1/6)
S = 72/(6/6 - 1/6)
S = 72/(5/6)
S = (72/1) divided by (5/6)
S = (72/1)*(6/5)
S = (72*6)/(1*5)
S = 432/5
S = 86.4
Answer: 86.4
note: this infinite sum formula only works if -1 < r < 1. In the case of r = 1/6 = 0.167 (approx), this r value is between -1 and 1.
Answer:
eight away .7 can be used into 3 4 times with a sum of 2.8 and that leaves .2 which would be left out since it is not a whole .7 so C

once you get to work.
Answer:
4
Step-by-step explanation:
- Add up your data. 3+13+11+5=32
- Divide the sum by the number of data you have. In your case you would divide 32/4/
- This will give you 8, which is your mean. Now, subtract 8 from each value and put the difference to its absolute value.
- Now, add up each of these values (5+5+3+3=16), then divide by 4. This will give you an answer of 4.
Hope this helps! Have a great day :)
