Expand and simplify 3(x+3) - 2(x+2)

The contents of 3838 cans of coke have a mean of x¯¯¯=12.15x¯=12.15. assume the contents of cans of coke have a normal distribution with standard deviation of σ=0.12.σ=0.12. find the value of the test statistic zz for the claim that the population mean is μ=12.μ=12.

Add the fractions and simplify 1/2+ 1/3

Can you me find the slope! (30 points)
