We can't use P = 2L + 2W because the sides have different lengths.

P = a + b + c + d

a = x

b = 2x

c = 2x - 2

d = x + 5

P = x + 2x + (2x - 2) + (x + 5)

P = <u>x + 2x + 2x</u> - 2 <u>+ x</u> + 5

P = 6x + 3

if x = 4:

P = 6 · 4 + 3

P = 24 + 3

P = 27

A total of 4 buses carrying 148 students from the same school arrive at a football stadium. The buses carry, respectively, 40, 3

Mandarinka [93]

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

Answer:

c = 5/9 (F-32)

F-32 = c ÷ (5/9)

F-32 = c × (9/5)

F-32= 9c/ 5

F= (9c/5) + 32
