Problem 2-11 (Algorithmic) Let A be an event that a person's primary method of transportation to and from work is an automobile and B be an event that a person's primary method of transportation to and from work is a bus. Suppose that in a large city P(A) = 0.48 and P(B) = 0.32. Are events A and B mutually exclusive? Yes What is the probability that a person uses an automobile or a bus in going to and from work? If required, round your answer to two decimal places. Find the probability that a person’s primary method of transportation is some means other than a bus. If required, round your answer to two decimal places. P(Bc) =

Joe bought an apple tree that was 48 inches in height. He noticed that this tree grew approximately 4 inches in height each year.Which statement best describes the function that could be used to model the height of the apple tree, h(t), as a function of time, t, in years.The height of the apple tree can be represented by a linear function, and the variable t is multiplied by 4 in the equation representing the function.The height of the apple tree can be represented by a linear function, and the variable t is an exponent in the equation representing the function.The height of the apple tree can be represented by an exponential function, and the variable t is multiplied by 4 in the equation representing the function.The height of the apple tree can be represented by an exponential function, and the variable t is an exponent in the equation representing the function.

The edge of a cube was measured to be 8 cm, with a maximum possible error of 0.5 cm. Use a differential to estimate the maximum possible error in computing the volume of the cube. (This next part is ungraded, just for fun. Using a calculator, find the actual error in measuring volume if the radius was really 8.5 cm instead of 8 cm, and find the actual error if the radius was actually 7.5 cm instead of 8 cm. Compare these errors to the answer you got using differentials).
