Overbooking is the practice of selling more items than are currently available. Overbooking is common in the travel industry; it

allows a vehicle (airline, train, bus, cruise ship, hotel, and so forth) to operate at or near capacity, despite cancellations, no-shows, or late arrivals.
Overselling is when more confirmed customers show up to use the vehicle than there is space available. When this happens, at least one customer will be denied the service that they paid for, either voluntarily (sometimes with an incentive provided by the supplier) or involuntarily. This is called getting "bumped."

Suppose that for a particular flight, an airline believes that 1% of ticket holders do not make the flight. The jet making the trip holds 188 passengers. If the airline sells 191 tickets, what is the probability that the flight will be oversold and they will have to bump a passenger? Assume that cancellations are independent.

Calculate the probabilities that one, two, and three people will be bumped, and then use those values to determine the probability that at least one passenger will be bumped. Give each answer to four decimal places. Avoid rounding within calculations.

P(one person is bumped)=

P(two people are bumped)=

P(three people are bumped)=

P(at least one person is bumped)=

Uma pessoa realizou uma compra que foi financiada em três parcelas mensais e iguais a R$ 350,00, o financiamento foi realizado s
lisabon 2012 [21]

Answer: Amount of purchase would be $393.70.

Step-by-step explanation:

One person made a purchase that was financed in three monthly installments and equal to $ 350.00, the financing was made at the compound interest rate of 48% a.a. Determine the amount of the purchase.

Since we have given that

Principal = $350.00

Rate of compounded monthly = 48%

Number of months = 3

So, the amount of purchase would be

Amount=350(1+\dfrac{0.48}{12})^3\\\\Amount=350(1+0.04)^3\\\\Amount=350(1.04)^3\\\\Amount=\$393.70

Hence, Amount of purchase would be $393.70.

What is the product (6r-1)(-8r-3)
eimsori [14]
Use the FOIL method (First, Outside, Inside, Last)

6r(-8r) = -48r²
6r(-3) = -18r
-1(-8r) = 8r          (note: two negatives multiplied together = positive answer)
-1(-3) = 3

-48r² - 18r + 8r + 3

Combine like terms:


-48r² - 18r + 8r + 3

-48r² - 10r + 3


-48r² - 10r + 3 is your answer

hope this helps

If a linear system has four equations and seven variables, then it must have infinitely many solutions. True or False
Savatey [412]

Answer:

The statement is False.

Step-by-step explanation:

Consider the provided information.

If a linear system has four equations and seven variables, then it must have infinitely many solutions.

We need to determine the above statement is true or false.

The above statement is false, it could be inconsistent, and therefore have no solutions,

For example:

x_1+x_2+x_3+x_4 +x_5+x_6+x_7=0\\x_1+x_2+x_3 =1\\x_4 +x_5 =1\\x_6+ x_7=1

Hence, there is no solution.

a ball is thrown with a slingshot at a velocity of 110ft/sec at an angle of 20 degrees above the ground from a height of 4.5 ft.
satela [25.4K]

Answer:

t=2.47\ s  

Step-by-step explanation:

The equation that models the height of the ball in feet as a function of time is

h(t) = h_0 + s_0t -16t ^ 2

Where h_0 is the initial height, s_0 is the initial velocity and t is the time in seconds.

We know that the initial height is:

h_0 = 4.5\ ft

The initial speed is:

s_0 = 110sin(20\°)\\\\s_0 = 37.62\ ft/s

So the equation is:

h (t) = 4.5 + 37.62t -16t ^ 2

The ball hits the ground when when h(t) = 0

So

4.5 + 37.62t -16t ^ 2 = 0

We use the quadratic formula to solve the equation for t

For a quadratic equation of the form

at^2 +bt + c

The quadratic formula is:

t=\frac{-b\±\sqrt{b^2 -4ac}}{2a}

In this case

a= -16\\\\b=37.62\\\\c=4.5

Therefore

t=\frac{-37.62\±\sqrt{(37.62)^2 -4(-16)(4.5)}}{2(-16)}

t_1=-0.114\ s\\\\t_2=2.47\ s  

We take the positive solution.

Finally the ball takes 2.47 seconds to touch the ground
