Common ratio = 28/7 = 4
8th term = (first term)4^7 = 114688
Tail: 51 inches or 4 feet and 3 inches
Whole Length: 6 times as much
51 x 6 = 306
306/12 = 25.5
The elephant is 25 feet and 6 inches long.
If 2 1/2 = 5n then n equals 1/2
Answer:
8
Step-by-step explanation:
Given that in a sample of n = 6 scores, the smallest score is X = 3, the largest score is X = 10
Mean = 6
Since mean = 6 we get sum of all the 6 scores = 
Now II part says 10 is changed to 20
i.e. original sum = 36
Changed value = 10
Adjusted value =26
Add: new value =22
New sum =48
So we have sum = 48
New mean= 
(This can also be done using the formula
old mean + positive change in one score/6)
