3.We-Haul rents a moving truck for 20.00$.and 0.45$.per mile. You-Haul rents the same size moving truck for 1.00$.per mile but with no upfront charge. Part A:Write two equations to represent the situation.

Part B:What is the rate of change for each? What do they represent?

Part C: Whatdo the -intercepts of each line represent?

Part D: Use the substitution method to help the renter determine when the two truck rentals will cost the same amount.

One of the inventors of integrated circuits observed that the number of transistors that fit on an integrated circuit will double every 24 months. what type of relationship most appropriately models this situation?

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.

What’s the answer? and how do i solve it ?
