Answer:
= 250
Step-by-step explanation:
To obtain any term in the geometric sequence multiply the previous term by the common ratio r
here r = - 5 and 
= - 2, hence
= - 2 × - 5 = 10
= 10 × - 5 = - 50
= - 50 × - 5 = 250
It is not about 36,000 because
about would be 3,600 or higher

Answer:
increase
Step-by-step explanation:
- Given data is: 71, 67, 67, 17, 69, 84, 21, 87
- Arranging in ascending order we find: 17, 21, 67, 67, 69, 71, 84, 87
- 4th term = 67, 5th term = 69
- -> median = Sum of 4th and 5th term/2 = (67 + 69)/2 = 132/2 = 66
- Now, when one of the 67 is replaced by 71, the new data set in ascending order will be: 17, 21, 67, 69, 71, 71, 84, 87
- Here, 4th term = 69, 5th term = 71
- New median = (69 + 71)/2 = 140/2 = 70
- -> new median > initial median
CONCLUSION: Median will increase if the number 71 replaced one of the 67's in the set.
Answer:
15.31
Step-by-step explanation:
solve both sides separately
6x+78/67-78x
x cancles out
becomes 84/-11
becomes -7.64 rounded
180+270-567
becomes -117
moves -7.64 to other side (divide by other side)
-117/-7.64
becomes 15.31
