Assume that there are three airlines from which to choose, each with a number of flights per day, and an on-time percentage show

n below. (Assume that delays occur randomly.) A traveler selects a flight at random, and it arrives on time.
Airline Num. of Flights On-Time Perc.
East-West Air 4 60
Air One 3 50
International Air 6 80

(1) What is the probability that the traveler flew on East-West Air?


(2) What is the probability that the traveler flew on Air One?


(3) What is the probability that the traveler flew on International Air?

<span>1.) The probability that the traveler flew on East-West Air is 4/(4 + 3 + 6) = 4/13 = 31%

2.) </span>T<span>he probability that the traveler flew on Air One is 3/13 = 23%

3.) </span>T<span>he probability that the traveler flew on International Air is 6/13 = 46%</span>

Answer:

  • 1,090.
  • 1.09k.

Step-by-step explanation:

<u>2 ways:</u>

  • 267 + 267 + 278 + 278
  • (267 + 278)*2

<u>Solve 1st way:</u>

  • 267 + 267 + 278 + 278
  • = (267 * 2) + (267 * 2)
  • = 534 + 556
  • = 1,090

<u>Solve 2nd way:</u>

  • (267 + 278)*2
  • = 545 * 2
  • = 1,090

Your answer is 1,090 or 1.09k.

What would be the equation of the cannonball’s path if it was launched with the same velocity, but from the ground instead?
natita [175]

The quadratic equation cannonball’s path if it was launched with the same velocity, but from the ground instead would be given by:

h(t) = -4.9t^2 + 19.8t

<h3>What is the quadratic equation for the height of a projectile?</h3>

Considering the gravity, it is modeled by:

h(t) = -4.9t^2 + v_0t + h_0

In which:

  • v_0 is the initial velocity.
  • h_0 is the initial height.

For this problem, we want:

  • The same initial velocity, hence v_0 = 19.8.
  • Launched from the ground, hence h_0 = 0.

Then, the equation is:

h(t) = -4.9t^2 + 19.8t
