I need answers for 9, 10, 11, please

9.the only thing biased in weather is the percentage it might be rounded up or down

10.Tuesday looks sunny

11. partly cloudy very little chance of rain with temperatures in the high 60s

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

the 4th choice is the correct one
