Kevin has a bag that contains orange chews, strawberry chews, and peach chews. He performs an experiment. Kevin randomly removes a chew from the bag, records the result, and returns the chew to the bag. Kevin performs the experiment 32 times. The results are shown below: An orange chew was selected 5 times. A strawberry chew was selected 17 times. A peach chew was selected 10 times. Based on these results, express the probability that the next chew Kevin removes from the bag will be peach chew as a percent to the nearest whole number.

Evaluate the following expression 1/3^2

It says factor each expression 49x-28?

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
