There are two blue marbles so you have a 2/8 probability of drawing a blue marble on each draw since the marble is replaced after the first draw. 2/8 can be simplified to be 1/4 and then converted to be 0.25 per draw. 0.25 plus 0.25 equals 0.5. Since we are dealing with percentages multiply 0.5 x 100 which equals 50. Now take 50 and divided by the total number of marbles in the bag which is 8. 50 divided by 8 equals 6.25. So it would be about 6%.

Find the distance from G to S.
OLEGan [10]
The distance formula is the square root of (x1-x2)^2+ (y1-y2)^2

So it would be square root [ (-2-3)^2 + (6-(-2))^2]
So it would be square root(25+64)
Square root(89)= 9.433

Ierofanga [76]

The area of the triangle is 2\sqrt{3} = 3.4641 square feet.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.

In the given triangle, the hypotenuse is the side that is represented by c. The other sides on the triangle are represented by the values a and b.

Step 2:

Assume the other side of the triangle measures x units.

So according to the Pythagorean theorem,

4^{2} = (2\sqrt{3} )^{2} + x^{2} , x^{2} = 4^{2} - (2\sqrt{3} )^{2} .

x^{2}  = 16 - 12 =4, x =2.

So the other side of the triangle, b measures 2 feet.

Step 3:

The area of a triangle is half the product of its base length and height.

The base length of this triangle is 2\sqrt{3} feet and the height is 2 feet.

The area of the triangle= \frac{1}{2} (2\sqrt{3} )(2) = 2\sqrt{3} = 3.4641.

The area of the triangle is 2\sqrt{3} = 3.4641 square feet.

The amount of water remaining in the pool is decreasing at a rate of
Gnom [1K]

The average rate of change has a relationship with slopes. In this way, we can write the slope of a line as follows:


Slope=\frac{Change \ y}{Change \ x}


As you can see in the graph, we have a straight line whose slope is negative. This slope as we have said is the Average Rate of Change we need to find. So, to find the slope of this line we must choose two points and compute the following formula:


ARC=Slope=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}}


The two points can be:


P_{1}(0,40) \ and \ P_{2}(10,0)


So:


ARC=\frac{0-40}{10-0} \\ \\ \therefore \boxed{ARC=-4 \ gallons \ per \ minutes}


Finally, the conclusion is:


<em>The amount of water remaining in the pool is</em><em> decreasing</em><em> at </em><em>a rate of 4 gallons per minute</em>
