Mike drives a taxi. his company pays him $0.32 for every half-mile driven and a $10 bonus for every 100 miles he drives. how much does mike earn for driving 380 miles?

.32 x 2 = $.64 (1 mile)

380 x .64 = $243.20

+ $10 x 3 ($10 bonus for each 100 miles) = $30

Total is $273.20

(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

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
