Answer:

A =153.86

Step-by-step explanation:

The volume of a rectangular prism is (x^3 – 3x^2 + 5x – 3), and the area of its base is (x^2 – 2). If the volume of a rectangula
bixtya [17]

Answer:

The height of the prism is equal to h=(x^{3}-3x^{2}+5x-3)/(x^{2}-2)

Step-by-step explanation:

we know that

The volume of a rectangular prism  is equal to

V=Bh

where

B is the area of the base of the prism

h is the height of the prism

In this problem we have

V=x^{3}-3x^{2}+5x-3

B=x^{2}-2

substitute in the formula and solve for h

x^{3}-3x^{2}+5x-3=(x^{2}-2)h

h=(x^{3}-3x^{2}+5x-3)/(x^{2}-2)

If 80% of scheduled flights actually take place and cancellations are independent events, what is the probability that 3 separat
Mekhanik [1.2K]

 

We are given that 80% of scheduled flights really take place, therefore this means that:

Probability of flying = 80% = 0.80

 

Now in statistics class, we know that the probability of two or more independent events to occur is simply equivalent to the product of their probabilities, or mathematically written as: (P = Probability)

total P = P1 * P2 * P3 *...

 

In this case, since we are to find for the probability that 3 independent flights will occur, therefore the total probability assuming equal probabilities to fly is:

total probability = 0.80 * 0.80* 0.80

total probability = 0.512

or

total probability = 51.20%

 

This means that there is only a 51.20% chance for 3 flights to occur.
