Answer:
There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.
Step-by-step explanation:
is the number of different combinatios of x objects from a set of n elements, given by the following formula.

In this problem, we have that:
Total number of combinations:

Desired combinations:
It is 1 one 5(contamined) and 2 of 17(non contamined). So:

What is the probability that exactly 1 of the tested bottles is contaminated?

There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.
For this case we have the following function:
F (x) = 3x ^ 2 + 6x-24
We observe that it is a quadratic equation.
The graph is therefore a parabola.
Its cut points are:
(-4, 0)
(2, 0)
Answer:
See attached image to see graph of the function
Imagine that you divide a piece of one unit into 125 equal length interval and you take just one of these 125 pieces, that's is 1/125
Answer:
The rectangle has sides AB, BC, CD, and AD. Then AC and BD are diagonals of the rectangle. The diagonals have the same length.
AC = BD
3x + 15 = 4x - 5
Solve the equation for x.
x = 20
Plug this value of x back into any of the expressions.
