Annie and alvie have agreed to meet between 5: 00 pm and 6: 00 pm for dinner at a local health-food restaurant. let x = annie's arrival time and y = alvie's arrival time. suppose x and y are independent with each uniformly distributed on the interval [5,6].a. what is the joint pdf of x and y? b what is the probability that they both arrive between 5: 15 and 5: 45? c if the first one to arrive will wait only 10 min before leaving to eat elsewhere, what is the probability that they have dinner at the health-food restaurant? (hint: the event of interest is a = {(x, y): |x-y| (greather than or equal to) (1/6)}

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
