Answer: a) The probability that a randomly selected high school student plays organized​ sports = 0.17

b) The randomly selected high school student is unlikely to play organized​ sports.

Step-by-step explanation:

Given : A survey of 400 randomly selected high school students determined that 68 play organized sports.

Then , the probability that a randomly selected high school student plays organized​ sports is given by :-

\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}\\\\=\dfrac{68}{400}=0.17

In percent , the  probability that a randomly selected high school student plays organized​ sports is 17%.

since 17% lies in the interval of unlikely events (0%, 25%).

It means that the randomly selected high school student is unlikely to play organized​ sports.

Patricia, Luca and Dauda shared an amount of money such that, Patricia had twice as much
inn [45]

Answer:

GH 1533

Step-by-step explanation:

Let Dauda's share of the money=x

Patricia had twice as much  as Dauda, therefore:

Patricia's share=2x

Luca had GH 600.00 more than Dauda, therefore:

Luca's Share =x+600

If Patricia had GH 2,000.00

Then: 2x=2000

x=1000

Therefore:

  • Dauda's Share=GH 1000
  • Patricia's share=GH 2000
  • Luca's Share =1000+600=GH 1,600

Next, we determine the average share.

\text{Average Share=}\dfrac{1000+2000+1600}{3}\\=\dfrac{4600}{3}\\\\=$GH 1533.33\\\text{Average Share} \approx $GH 1533 (to the nearest GH)

Murrr4er [49]

Answer:

  (b) distance, y=20x, 480 mi

Step-by-step explanation:

As is often the case, the only self-consistent answer choice is the correct one.

__

The dependent variable is plotted on the y-axis, so is distance.

(x, y) = (2, 40) tells you y = 20x is an appropriate choice of equation.

In 24 hours, the dragonfly will fly y = 20(24) = 480 miles.
