A probability model includes P(red) = 27 2 7 and P(blue) = 314 3 14 . Which of the following probabilities could complete the model? Select all that apply. A. P(green) = 27 2 7 , P(yellow) = 27 2 7 B. P(green) = 38 3 8 , P(yellow) = 18 1 8 C. P(green) = 14 1 4 , P(yellow) = 14 1 4 D. P(green) = 521 5 21 , P(yellow) = 1121 11 21 E. P(green) = 37 3 7 , P(yellow) = 114 1 14

Answers

Answer:

[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]

[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]P(Red) = \frac{2}{7}[/tex]

[tex]P(Blue) = \frac{3}{14}[/tex]

Required

Which completes the model

Let the remaining probability be x.

Such that:

[tex]P(Red) + P(Blue) + x = 1[/tex]

Make x the subject

[tex]x = 1 - P(Red) - P(Blue)[/tex]

So, we have:

[tex]x = 1 - \frac{2}{7} - \frac{3}{14}[/tex]

Solve

[tex]x = \frac{14 - 4 - 3}{14}[/tex]

[tex]x = \frac{7}{14}[/tex]

[tex]x = \frac{1}{2}[/tex]

This mean that the remaining model must add up to 1/2

[tex](a)\ P(Green) = \frac{2}{7} ; P(Yellow) = \frac{2}{7}[/tex]

[tex]P(Green) + P(Yellow)= \frac{2}{7} + \frac{2}{7}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{2+2}{7}[/tex]

[tex]P(Green) + P(Yellow)= \frac{4}{7}[/tex]

This is false because: [tex]\frac{4}{7} \ne \frac{1}{2}[/tex]

[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{3}{8} + \frac{1}{8}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{3+1}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{4}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]

This is true

[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{4} + \frac{1}{4}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{1+1}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{2}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]

This is true

Other options are also false

Step-by-step explanation:

To do this, you can see that the number 7 and the number 56 are right by each other, divide 56 by 7 which is 8, and since 7 times eight is 56, then multiply 13 times 8 and simplify the answer.
And do the same thing with number B, since 8 divided by 56 it’s 7, then you just got to multiply 14 times 7 and put your answers on top of the missing value *56* and simplify it. And you will know which one has more sugar per fluid ounces

On the side and top of diagram B, you are given 4 different options for clothing and 3 for the color. This chart shows all the possible combinations as well, meaning that option B is right too.

On top of this, you can also notice that both diagrams A and B have the same labels, just moved around.

Find the area of the trapezoid 2 2 2 2 4

Answers

Answer:

It is 10.

Step-by-step explanation:

If we just find the area for each section and add them all up it would equal 10. The first triangle, 2x2=4 then divide that by 2 will equal you 2. Then the square is just 2x2 =4. Then the last triangle, 2x4=8 then divide that by 2 = 4. 2+4+4=10.

Answer:

Correct answer is (10)

Step-by-step explanation:

since 2 triangles come together to form a square\rectangle

length * width = Area

we can find both areas of the triangles:

left triangle: 2*2 = 4 --> 4 devided in half = 2

square area = 4

right side triangle: 2*4 = 8 ---> devided in half = 4

______________________________________

next add up all the measurements for each piece:

left triangle + middle square + right side triangle = area

(2+4+4 = 10)

Angle 3 is 72

Angle 4 is 18

Angle 5 is 90

Angle 6 is 72

Step-by-step explanation:

Sum of straight angle is 180

So 180 = (90+18+x) for angle 3

90+18 gives you 108 and since a straight angle is 180, you have to subtract 108 from 180 which gives you 72.

56.52 you’re going to take the radius times 2 to get diameter and then diameter times pi or 3.14
The formula for area of a circle is A=πr^2
Radius is the distance halfway across the circle so in this case, r=9
Now just plug the radius value into the equation:
A = π(9)^2 —> A = π(81) —> A = 254.34 —> round to the nearest tenth A = 254.3
**keep in mind we use 3.14 for π**

Hong made 2 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for both necklaces was 10.40 If the beads cost 2.50 for each necklace, how much did each pendant cost?

Answers

b+ p= 10.40
b=2x 2.50
Now using substitution method replace b in first equation with value of second equation basically combing the two equations into one do you end up with one variable to solve .
2 x 2.50 +p =10.40
5 + p=10.40
P=$5.40
b =$5.00
The answer is EACH pendant cost $2.70

Item 8Too FastBatniks father was a great inventor. He had created many things that made peoples lives easier. One of his inventions was a car that could operate on both water and land; this car was Batniks favorite. On water, it could float and travel at speeds up to 80 miles per hour. But on land, it could travel at speeds over 200 miles per hour. Batniks father had created this special car to help people from their island get to the mainland and other islands faster. When Batnik's father was a boy, the only method of travel from one island to another was by ferry, and the trip often took hours. People who were sick and needed medical help from the mainland would have to endure the long crossing or not go at all because of delays. Batniks father loved his homeland and wanted to ease the burden on the people, so he created the water car.When he showed the car to Batnik, Batniks father warned Batnik that the car should not be driven at the maximum speed on land or water because the engine could burst into flame. One day when his father was away, Batnik decided that he wanted to show the car to his friends. He drove it on the water, at first going only half the possible speed. Then, as his excitement grew, he increased his speed on the water and was nearing maximum speed. When he reached the land, he continued to accelerate. His exhilaration grew. Like the mythological Greek boy Icarus, who flew too close to the sun, Batnik forgot his fathers warning and pushed the gas pedal to the floor. When the car exceeded 200 miles per hour, it burst into flames.How is the character of Batnik's father in Too Fast similar to Pan in "Pan: God of the Wild"?Both act in ways that cause the deaths of young people.Both help people with new inventions.Both have aspects of joy and terror.Both travel throughout the world in unusual ways.
