To determine the number of possible arrangements for 6 out of 8, we should use combinations. That is
ₐC₆ = 8!/(6!2!)
Answer: b. Combination
Answer:
1) 1/6, 1/3, 1/2, 3/4
2) 3/10, 2/5, 7/10, 4/5
3) 1/4. 7/12. 2/3, 5/6
4) 4/15. 11/30, 2/5, 7/10
Step-by-step explanation: Either convert all in a set to a common denominator, or convert to decimal fractions.
Mean is the same as average. Adding up all the amounts then dividing it by the number of amounts. In this case, we add up all the snowfall amounts and then we divide it by 10 ( the count or number of snowfall amounts).
In equation,
(13+19+16+23+11+18+14+26+13+16) / 10 = 16.9
Th answer is A. 16.9 inches.
