1000m equals 1km so 600m equals 0.6km.
10^3 CDs with CD = $12 then total CDs earnings is (10^3)(12) = $12,000
10^2 CD players with CD plater = $35 then total CD player earnings is (10^2)(12) = $1,200
Total store earnings = ($12,000 + $1,200) = $13,200
$300 because 300x2=600 then 75x8=300 and 600+300=900
To answer this item, find first the z-score of the given data.
z-score = (x - m) / d
where x is data point, m is the mean and d is the standard deviation
Substituting the given values,
z-score = (188 - 176.7) / 9.9 = 1.14
This translates to a percentage of 87.29%.
Because we are asked of the percentage of those with height greater than this, that would be,
100 - 87.29% = 12.71%
Answer: 12.71%
