Serga [27]

Answer:

0.0159

Step-by-step explanation:

Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight.

Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)

The plane is overbooked if more than 150 show up

i.e. less than 2 do not show up

Hence the probability that the airline overbooked this flight

= $P(X$

Colby wants to set square tiles on the top of a wooden box. The top of the box is a rectangle7 1/2 inches long and 5 1/2 inches

Nostrana [21]

Multiply 7 1/2 by 5 1/2 and get 41 and 1/4

now divide 41 1/4 by 1/2 and get 83..

83 would be your answer(I got a little confused so this might be wrong D:)

g Farmer Violet wants to enclose one 990 square foot rectangular area of land using fencing. One side will use special fencing c

saw5 [17]

Answer:

Sides of the rectangular area:

x = 30 f

y = 33 f

Step-by-step explanation:

Let´s call x and y the sides of the rectangular area

A = x*y = 990 y = 990/x

The function cost is:

C = Costs ( sides x) + costs ( sides y )

Cost of sides x = 12*x + 10x

Cost of sides y = 10*y + 10 *y = 2*10*y = 20*y

C = 12*x + 10*x + 20*y = 22*x + 20*y

The function cost as function of x is:

C(x) = 22*x + 20*(990/y) = 22*x + 19800/x

Tacking derivative on both sides of the equation:

C´(x) = 22 + [ - 19800/x²]

C´(x) = 0 22 - 19800/x² = 0

Solving for x

22*x² - 19800 = 0

22x² = 19800

x² = 19800/22 = 900

x₁,₂ = ± 30 We dismiss negative root ( we never have negative lenghts)

Then x = 30 f

And y = 990 / 30 y = 33

To see if x = 30 is a minimum for function C(x) we evaluate the second derivative.

C´´(x) = 2*x* 19800/x⁴

C´´ (x) = 39600/x³ so C´´ is always greater than 0 then C (x) has a minimum at x = 30

Sides of the rectangular area are:

x = 30

y = 33
