Suppose a plane has 500 seats. From experience, it's known that 10% of people who have bought the ticket do not show up. Now, 55
oksano4ka [1.4K]

Answer:

The probability that there will be enough seats for all people who turn up is 0.78

Step-by-step explanation:

Given:

A = 500

B = 550

Since it is known from experience that 10% of people who bought tickets don't show up, to find the probability that there will be enough seats for those who show up, we have:

Percentage that will turn up = 100℅ - 10℅ = 90℅

Since 90℅ will turn up, that means the number of passengers will be less than 500.

Therefore for P less than or equal to 500, we use:

P ( X <_ 500) =

= [500 + 0.5 - (550 * 0.9)] / sqrt*(550 * 0. 9 * 0.1)

= 0.78

Therefore, the probability that there will be enough seats for all people who turn up is 0.78

Suppose that you buy a two-year 8% bond at its face value.
Juliette [100K]

Answer:

Real Rate of Return = 4.9%  and Nominal rate = 0.08 or 8%

Real Rate of Return = 2.9%  and Nominal rate = 0.081 or 8.1%

real rate = 5 %   and Nominal rate = 0.0815 or 8.15%

real rate = 3%  and Nominal rate = 0.0815 or 8.15%

Step-by-step explanation:

given data

time period = 2 year

Coupon rate = 8% =  0.08

Inflation rate 1st year = 3% =  0.03

Inflation rate 2nd year = 5% =  0.05

solution

we get here Real Rate of Return  that is express as

Real Rate of Return = (Coupon Rate - Inflation rate) ÷ (1+Inflation rate)   .........1

so that here 1st year Real return  will be

Real Rate of Return = (0.08 - 0.03) ÷ (1+0.03)

solve it we get

Real Rate of Return = 4.9%

and

(1 + nominal rate) = (1 + real rate) × (1 + inflation rate)     ............2

(1 + nominal rate) = (1 + 0.049) × (1 + 0.03)

Nominal rate = 0.08 or 8%

and

for 2nd year Real return  will be

Real Rate of Return = (0.08 - 0.05) ÷ (1+0.05)

solve it

Real Rate of Return = 2.9%

and

(1 + nominal rate) = (1 + real rate) × (1 + inflation rate)     ............3

(1 + nominal rate) = (1 + 0.029) × (1 + 0.05)

Nominal rate = 0.081 or 8.1%

and

now for the bond Treasury Inflation-Protected Securities, we get real and nominal return that is

for 1st year

Real rate = Coupon rate - Inflation     ...............4

Real rate = 0.08 - 0.03

real rate = 0.05

and

(1 + nominal rate) = (1 + real rate) × (1 + inflation rate)     ................5

(1 + nominal rate) = (1 + 0.05) × (1 + 0.03)

so

Nominal rate = 0.0815 or 8.15%

and for 2nd years  it will be

Real rate = Coupon rate - Inflation      ....................6

Real rate = 0.08 - 0.05

real rate = 0.03

and

(1 + nominal rate) = (1 + real rate) × (1 + inflation rate)     ...................7

(1 + nominal rate) = (1 + 0.03) × (1 + 0.05)

so

Nominal rate = 0.0815 or 8.15%

A pole is made to lean against a wall. The base of the pole is placed 7 feet
Brums [2.3K]

Answer:

22.14

Step-by-step explanation:

Using the Pythagorean Theorem:

a^2 + b^2 = c^2

21^2 + 7^2 = c^2

441 + 49 = c^2

490 = c^2 (square root both sides so c^2 becomes c)

c = 22.13594363 (round to hundredths)

c = 22.14
