Answer:
A) 4
B) Mode is 5
C) 10.5
Step-by-step explanation:
A) 62+x/12
(62 + x) ÷ 12 = 5.5 ×12
62 + x = 66
×= 66-62
×=4
B) mode is the highest occuring no which is 5
C) mean has been given as 5.5; mean plus mode= 10.5
Answer:
Step-by-step explanation:
21 + 18 = 39
147/39 = 3.7692307692307
3.7692307692307 x 18 = 67.846153846152, round to 67.80 and that's your answer
we have been asked to find the sum of the series
As we know that a geometric series has a constant ratio "r" and it is defined as
The first term of the series is
Geometric series sum formula is
Plugin the values we get
On simplification we get
Hence the sum of the given series is
