Answer:
B: Permutation; Number of ways are 60
Step-by-step explanation:
At a competition with 5 runners, medals are awarded for first, second, and third places.
Each of the 3 medals is different.
This is a case of Permutation and the Number of ways are 60.
We have to award 3 medals among 5 runners.
This can be done in 5P3 ways.
=
=
=
Therefore, the answer is option A.

Answer:
$216
Step-by-step explanation:
Do = 0.2. Now you do 270 x 0.2, which equals 54. Finnaly you do 270-54, which equals 216. So now you have your answer.
The graph which best represents the new function is a linear function on a coordinate plane as shown in the image below.
<h3>How to determine the graph of the new function?</h3>First of all, we would determine the slope of the linear function as follows:
Slope, m = ⅔.
Multiplying by -4, the new slope is:
Slope = ⅔ × -4
Slope = -8/3 or 2.7.
For the equation of this line, we have:
y - y₁ = m(x - x₁)
y - 0 = -8/3(x - 3)
y - 0 = -8/3x + 8
y = -8/3x + 8
Decreasing the y-value by 1, we have:
y = -8/3x + 8
y = -8/3x + 8 - 1
y = -8/3x + 7
Therefore, we would have a linear function on a coordinate plane as shown in the image attached below.
