Answer:

V(X)= 39.10

V(Y)= 40

Step-by-step explanation:

Given that

Total number of student = 140

Bus A - 31

Bus B- 43

Bus C- 27

Bus D- 39

The probability that a student was on the bus is proportional to the number of student. Eg 31/140 in bus A, 43/140 on bus B, ...

E(X) = (31*31/140) + (43*43/140) + (27*27/140) + (39*39/140)

= 35.5

$Var(X) =(31-35.5)^2 \times \dfrac{31}{140}+(43-35.5)^2 \times \dfrac{43}{140}+(39-35.5)^2 \times \dfrac{39}{140}+(27-35.5)^2 \times \dfrac{27}{140}$

V(X)= 39.10

The bus driver have 1/4 probability on being on any of the buses.

E(Y) = 140/4 = 35

$Var(Y)=\dfrac{(35-31)^2+(35-43)^2+(35-27)^2+(35-39)^2}{4}$

V(Y)= 40

Answer:

162 inches.

Step-by-step explanation:

Please consider the complete question.

Carlos is helping his grandmother make a rug. They have 5 yards of fabric, which is equal to 180 inches. They need an additional of 4 1/2 yards of fabric to finish the trim. How many inches are in $4\frac{1}{2}$ yards?

Let us convert $4\frac{1}{2}$ into improper fraction as:

$4\frac{1}{2}=\frac{4\cdot 2+1}{2}=\frac{8+1}{2}=\frac{9}{2}$

Now, we will use proportions to solve our given problem as:

$\frac{\text{Inches}}{\text{Yard}}=\frac{180}{5}$

$\frac{\text{Inches}}{\text{Yard}}=36$

$1\text{ Yard}=36\text{ Inches}$

To find number of inches in 9/2 yards, we will multiply 9/2 by 36 as:

$\frac{9}{2}\text{ Yards}=\frac{9}{2}\times 36\text{ Inches}$

$\frac{9}{2}\text{ Yards}=9\times 18\text{ Inches}$

$\frac{9}{2}\text{ Yards}=162\text{ Inches}$

Therefore, there are 162 inches in $4\frac{1}{2}$ yards.
