Atotal of 4 buses carrying 148 students from the same school arrives at a football stadium. the buses carry, respectively, 40, 33, 25 and 50 students. one of the students is randomly selected, each student with equal probability. let random variable x denote the number of students who were on the bus carrying the randomly selected student. one of the four bus drivers is also randomly selected, each driver with equal probability. let random variable y denote the number of students on the bus of the randomly selected driver.(a) which of e[x] or e[y] do you think is larger? why? (b) compute e[x] and e[y]

The avenues in a particular city run north to south and are numbered consecutively with 1st avenue at the western border of the city. the streets in the city run east to west and are numbered consecutively with 1st street at the southern border of the city. for a festival, the city is not allowing cars to park in a rectangular region bordered by 5th avenue to the west. 9th avenue to the east, 4th street to the south, and 6th street to the north. if x is the avenue number and yis the street number, which of the following systems describes the region in which cars are not allowed to park? 5th ave 9th ave

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.
