There are 1,000 balls in a container. All of the balls are the same size and shape. In the container, there are • 400 red balls; • 250 orange balls; • 100 green balls; and • 250 yellow balls. A student will pick one ball at random from the container. What are the probabilities that the student will pick a ball that is either red, orange, or green? Write the three different ways to represent this probability.

They are wording it tricky, but it is simple. So first if you combine all the balls together there are 7, and 3 blacks ball 3/7.

Answer:

I believe you have the correct answer

Step-by-step explanation:

The probability of drawing a black marble from bag 1 is 2/3.

The probability of drawing a black marble from bag 2 is 1/4.

Since it is consecutive draws, we would multiply the 2 odds.

2/3 * 1/4 = 1/6

Answer:

x = 5 ± √46

Step-by-step explanation:

[tex]-x^2 + 10x + 21 = 0[/tex]

Take -1 common from L.H.S.

[tex]=> -1(x^2 -10x - 21) = 0[/tex]

Take -1 to R.H.S.

[tex]=> x^2 - 10x - 21 = 0[/tex]

Solve x using quadratic formula.

[tex]=> x = \frac{-(-10) + \sqrt{10^2 - 4 \times (-21) \times 1} }{2 \times 1} \: or \:\frac{-(-10) - \sqrt{10^2 - 4 \times (-21) \times 1} }{2 \times 1}[/tex]

[tex]=> x = \frac{10 + \sqrt{100 + 84} }{2} \: or \:\frac{10 - \sqrt{100 + 84} }{2}[/tex]

[tex]=> x = \frac{10 + \sqrt{184} }{2} \: or \: \frac{10-\sqrt{184} }{2}[/tex]

[tex]=> x = \frac{10 + 2\sqrt{46} }{2} \: or \: \frac{10 - 2\sqrt{46} }{2}[/tex]

[tex]=> x = (5 + \sqrt{46} ) \: or \: (5 - \sqrt{46} )[/tex]

Answer:

16.125 is the perimeter

Step-by-step explanation:

Multiply 15.375 × 3 because a triangle has three sides and is equilateral.

15.375 × 3 = 16.125

Have a great day!

Answer:

6

Step-by-step explanation:

all you have to do is divide 54 by 9 because area is length times width

Answer:

6

Step-by-step explanation:

Area of a rectangle: l x b (Length x Breadth)

Note: Breadth is the same as width

Area = 54

Length = 9

Breadth = 54/9

             = 6

Hope this helped!!!! :))

Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

After Saturday, there was [tex]\frac{5}{8}[/tex] of the journey left. [tex]\frac{3}{5}[/tex] of that would be:

[tex]\frac{5}{8}[/tex] *  [tex]\frac{3}{5}[/tex] = [tex]\frac{15}{40}[/tex] = [tex]\frac{3}{8}[/tex] of the journey.

Thus, the answer is 3/8

Answer:

A. 44/625

Step-by-step explanation:

There are 25 marbles total. To first calculate the probability of picking a yellow marble first can be represented as 11/25, the probability of picking blue is 4/25. We multiply these to figure out the probability of finding a yellow marble and then a blue one.

11/25 x 4/25 = 44/625

Answer:

A) 2

Step-by-step explanation:

a = 2

Answer:

Margarita gastó $40.43.

Step-by-step explanation:

Tenemos la siguiente información.

km recorridos por Margarita

42 km - ciudad

387 km - autopista

Rendimiento del carro

1 galon cada 28 km - ciudad

1 galon cada 36 km - autopista

Hacemos el siguiente factor de conversión

Ciudad

[tex]42 km \times \frac{1\: galon}{28\: km}=1.5\: galones[/tex]

Autopista

[tex]387 km \times \frac{1\: galon}{36\: km}=10.75\: galones[/tex]

Ahoa, se sabe que 1 galon cuesta $3.30. Por lo tanto, el costo de viaje será:

Total galones = 1.5 + 10.75 = 12.25 galones

Total costo = 3.30*12.25 = $40.43.

Answer:

1/216

Step-by-step explanation:

Hi, the probability of rolling it once is 1/6, twice in a row results in multiplying 1/6 by 1/6.

Therefore, three times means using the formula: (1/6)^3

Which gives us the fraction 1/216

The solutions for the given quadratic equation are:4/5 and 1/2.

The quadratic function can represent a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

For solving a quadratic function you should find the discriminant:[tex]D=b^2-4ac[/tex]  . And after that you should apply the discriminant in the formula: [tex]x_{1,\:2}=\frac{-b\pm \sqrt{D}}{2a}[/tex].

For the given question, you have:

a=20

b=-26

c=8

[tex]D=b^2-4ac=\left(-26\right)^2-4\cdot \:20\cdot \:8=676-640=36[/tex]

[tex]x_{1,\:2}=\frac{-b\pm \sqrt{D}}{2a}\\ \\ x_{1,\:2}=\frac{-(-26)\pm \sqrt{36}}{2*20}\\ \\ x_{1,\:2}=\frac{\left26\right\pm \:6}{40}[/tex]

Then,

[tex]x_1=\frac{\left(26\right)+6}{40}=\frac{32}{40}=\frac{4}{5}[/tex]

[tex]x_2=\frac{\left26\right-6}{40}=\frac{20}{40}=\frac{1}{2}[/tex]
