Answer:
x-axis
Step-by-step explanation:
4 km/h because 10-2 because of the 2 km left which =8 then you divide that by 2 to figure out the km per hour which = 4 so 4 km/h
675840 feet that's the answer I'm sure of it
It would be exactly $3.00
Answer:
76.2838
Step-by-step explanation:
E[X+Y] = E[X] + E[Y]
E[X] is the average of X or expectancy of X
E[Y] is the average or expectancy f Y
E[X] = 40P(student is in bus 1)+33P(student is in bus 2)+25P(student is in bus 3)+50P(student is in bus 4)=
40(40/148) + 33(33/148) + 25(25/148) + 50(50/148) = 39.2838
E[Y] = (number of students)/(number of drivers) = 148/4 = 37
So E[X+Y] = 39.2838 + 37 = 76.2838
