A baseball player hits a ball at an angle of 56° and at a height of 4.2 ft. If the ball’s initial velocity after being hit is 154 ft./s and if no one catches the ball, when will it hit the ground? Remember that the acceleration due to gravity is 32 .

G(x)=x2-16xb=-16, so =16 = 649(x) = (x2 - 16x + 64) - 649(x) = (x - 1)2-

The chart below shows the distribution of weeds in yard

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.
