Answer 1

Answer: For the first one, 12.5% chance

Step-by-step explanation:

The probability of flipping a coin and getting tails is 50%. Then, if you were to flip two coins and get both tails, you would have to divide the 50% by 2, which is equals to 25% of flipping two coins and getting them both tails.

So now we know...

Flipping one coin gives you 50% tails and 25% of flipping two coins and getting two tails

So now, we do it again with the third coin. We would divide the 25% by 2, which will get us to a 12.5% of getting all tails, or in fractions, 1/8

I’m not exactly sure about the other ones but I hope you found this one helpful!

Answer 2
1. It’s easiest to visualize if you write down all of the options that are possible when flipping a coin 3 times.
TTT
TTH
THT
THH
HHH
HHT
HTH
HTT
(i believe thats all of the options, if not adjust as needed)
but TTT is 1 out of the 8 possibilities, making the probability of getting three tails 1/8 or .125

2. There are two possibilities for getting a sum equal to three with two dice being rolled. Rolling a 1 and rolling a 2 or rolling a 2 and rolling a one.
You have 36 different combinations total, making your fraction 2/36

2/36 still needs to be simplified by dividing by two

your answer is 1/18 or .55555 repeating

3. There is no black section on the spinner so there is no way to land on a black section. The probability is 0

4. I believe this question is asking about the theoretical probability of flipping a coin, which is 1/2 or .5

5. You’ve got a theoretical probability of 3/6 or 1/2 chance to roll less than a four. If you roll the cube 24 times, you should expect to get 12 (half of 24) rolls less than four.

6. The probability of choosing a red marble is 5/30 or 1/6. The marbles are always replaced so your probability doesn’t change.

Noah pulls 60 marbles out and replaces them. 1/6 of those marbles should be red.

1/6 of 60 is 10

10 marbles should be red

7. There are 11 balls total. 5 of those are green (5/11), 3 of them are red (3/11), 2 of them are white (2/11), and 1 of the balls is orange (1/11).

The probability of choosing an orange ball (the least occurring) is 1/11 or .090909 repeating

8. Adrian has a 1/4 chance of being put in any singular section. He volunteers 20 times. We’re trying to figure out how many times he was put in either the cat or the reptile section.

If we add the probabilities of the cat and reptile assignment, you get 1/2.
1/2 of 20 is 10

Keeping the probabilities separate and adding the occurrences together at the end will give you the same answer.
1/4 of 20 is 5
Add another 1/4, which is 5+5 and it’s 10

9. Let’s label the four sections on the spinner 1, 2, 3, and 4. The outcome of the coin flip will either be heads or tails.

The combinations could be:

1 H
2 H
3 H
4 H
1 T
2 T
3 T
4 T

That totals to 8 possible outcomes.

You can multiply the two outcome numbers together to achieve the the same answer:

2(4) = 8

add the whole numbers 9+3=12 the denomonaters are the same so keep them the same add the numerators 7+3= 10 and 10-8= 2 so add one to your whole number and have two as ur numerator so now you have thirteen and two eighths or 13 2/8

Jake's apple farm has 228 apple trees. Last year, 182,172 apples were produced at Jake's apple farm. If each apple tree produced the same amount, how many apples did each tree produce?

Answers

Answer:

799 apples were produced by each tree.

Step-by-step explanation:

182,172 apples evenly produced by 228 trees.

182,172 apples ÷ 228 trees = 799 apples per tree

799 apples • 228 trees = 182,172 apples

Last question:

Answers

Answer:

y=-3x+7

Step-by-step explanation:

Rise/run

To find slope you can use the rise/run strategy. You count how many units up/down and then how many right/left. between each point on the line, it was down 3 units, right 1 unit (3/1) and since it was going down it would be negative.

As for the y-intercept, you look at where the line crosses the y-axis. In this case it was at (0,7), so the answer would be 7.

Plug your answers in and your equation should be y=-3+7.

You could also do y=7-3x, its the same equation but reversed, so you'll get the same line.

Hope this helps :)

On a coordinate plane, a line has a negative slope.
On a coordinate plane, a line curves up.
On a coordinate plane, a line curves down, levels off, and then curves down.

Answers

Answer:

On a coordinate plane, a line has a negative slope

Step-by-step explanation:

A linear function is a function whose graph is a straight line. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function.
