The rules of operations to simplify 2 3-4 (5.4)
I think the answer is irrational
Standard Deviation, σ: 1.870828693387
Count, N: 4
Sum, Σx: 12
Mean, μ: 3
Variance, σ2: 3.5
So, youd start by adding the two sales together to get total sales. Then you would divide that number by the gas sales to get the percent
65560+36740 = x
36740/ x = the percentage :)
