<h2>The chances of receiving two greens are 5/31.</h2>

<em>Given a bag containing four blue, three red, and five green marbles, the total result is:</em>

<em>Total number of balls = 4 + 3 + 5 = 12</em>

<em>If green is chosen first, the chances of picking a green are 5/12.</em>

<em>The probability that the second stone is green is 4/11 if it is picked and not replaced (4 greens remaining)</em>

<em>The chance of earning two greens is 5/12 4/11.</em>

<em>The chance of getting two greens is 20/132.</em>

<em>The chance of earning two greens is 5/31.</em>

<h3><em>As a result, the chance of getting two greens is 5/31.</em></h3>

Answer:

The slope is $-50$ . The slope means that the amount of money in the account is decreasing at a rate of $ $50$ every week.

Step-by-step explanation:

Given coordinates are $(4,2400)\ and\ (12,2000)$

We need to find the slope of the graph, and explain what does slope means for this graph.

The formula for computing slope $(m)$ is

$m=\frac{y_2-y_1}{x_2-x_1}$

Where $(x_1.y_1)$ and $(x_2,y_2)$ are the point on the line.

Let us plug points $(4,2400)\ and\ (12,2000)$ in the equation

$m=\frac{2000-2400}{12-4}\\ \\m=\frac{-400}{8}\\\\m=-50$

Here, the negative sign of slope $(m)$ represents that the value of the function (budget) is decreasing, with an increase in time (week).

The slope is $-50$ . The slope means that the amount of money in the account is decreasing at a rate of $ $50$ every week.

In which quadrant is the number –14 – 5i located on the complex plane?

AlekseyPX

On the complex plane, the real component of a complex number is graphed along the horizontal axis while the imaginary component is graphed along the vertical axis.

Positive numbers go to the right on the real axis and up on the imaginary axis, and vice versa for negative numbers.

Therefore, the number -14-5i is in the 3rd quadrant because it graphed to the left of the origin and down.
