Let X denote the total snowfall in the Twin Cities in December of a given year, measured in centimeters. The five-number summary for X is given by:Min. Q1 Median Q3 Max.0.0 8.4 17.4 30.9 85.3What is the most likely value for the mean of X?a) 15.2b) 21.9c) 53.9d) 4.9

Concept: Caclulating Standard Variables

We have a five number summary which is more than enough information to calculate our mean.The mean is the sum of all the numbers divided by the nth number of numbers.Note that we can only find a rough estimation not the EXACT value We do (min +max + 2(Q1+median+Q3))/8 Now let's plug in our values!(0+85.3+2(8.4+17.4+30.9))/8 Which gives us option BHope this helps, give brainlist

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
