Answer:
1
Step-by-step explanation:
i^12
We use the rule of 4
Take the exponent and divide by 4
12/4 = 3 r0
Then look at the remainder, That is the power we use
i^0 =1
i^1 =i
i^2 = -1
I^3 = -i
It repeats
i^0 =1
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
