Because the choices concern more about the median, the median of Data set A is equal to 17. The median of Data set B is 16. Thus, the median for A is not exactly similar to the median of B.
The range of Data Set A is 8 while that of Data Set B is 7. Thus, the range of A is greater compared to B.
If you divide 61 by 6 and it is not an integer, it is not a multiple of 6.
The number is 6 because 14+6=20 and 6 is less than 14. Hope this helps.
I'm guessing we have
S1 = 1000
S2 = 1000 + 500
S3 = 1000 + 500 + 250
S4 = 1000 + 500 + 250 + 125
S5 = 1000 + 500 + 250 + 125 + 62.5
Just adding that up, S5 is
Answer: 1937.5
Do they want you to use the geometric series formula? We'll check it that way.
We have first term a=1000 and common ratio r=1/2. In general
For us that's
S5 = (1000 (1 - (1/2)^5))/(1 - 1/2) = 2000(1 - 1/32)
= 2000(31)/32 = 62000/32 = 1937.5 √
Math works!
