Answers

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!

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

Answer:

1,142.5 or 1,143

Step-by-step explanation:

Part A: Start by writing out the equation a2 + b2 = c2. Since both sides a and b are known, fill it in. So, now it is 38 squared + 29 squared = c2. Next, you have to find the square roots for both sides, or legs. For 38 squared, it will be 38 x 38 = 1,444. For 29 squared, it will be 29 x 29 = 841. Now that we both legs, we add that together: 1,444 + 841, which equals 2,285. Then, you need to divide 2,285 by 2, which is 1,142.5

Since you need to round, it would be 1,143.

Part B: 1,143

The answer is 1,143.

The rectangle is 1.8 km wide and 4 km long.Solve the area for the triangle. The equation l · w ÷ 2=A will help. So, the equation would be 4 · 2.2 ÷ 2=4.4Then, solve the area for the rectangle by using the equation l · w=A. 1.8 · 4=7.2Add them together. 4.4+7.2=11.6Final answer - 11.6 km²

Do the calculation below

6(18 + 14)

Answers

Answer:

Explained below...

Step-by-step explanation:

First, recognize the acronym PEMDAS, which stands for:

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

So, as there are parenthesis, that will be your first step in the expression.

6(18 + 14) --> 6(32)

Now, you will find the next step in PEMDAS, which would be multiplication.

6 * 32 = 192.

So, your answer for the equation is 192.

Hope this helps! :)

Step-by-step explanation:

Answer:

c)

Step-by-step explanation:

so we know that the total amount of students in said school is 180, which means that the total amount of girls in this school cannot be greater than 180

with that, let us get to solving these equations to see which one is less than 180-

a) 85/10*180=1530>180

b) 850/100*180=1530>180

c)0.85*180=153

'c' is the only answer choice less than 180>153

another way to solve this would be to focus solely

on answer choice 'c'-

so 85% of the school is female and 85% as a fraction is 0.85, and we need to find the total amount of girls that attend said school and the only way to do that is to multiply-

0.85*180=153>180

Answer:

I believe x = 12

Step-by-step explanation:

If the triangles were similar then they would have the same angle measures.

Steps:

Add angle K and L: 90 + 54 = 144

Subtract the added angles from 180 to find angle J: 180 - 144 = 36

Angle J is similar to angle X so, divide 36 by 3: 36/3 = 12
