Aimee has 2 sisters in her family. She thinks the probability of a family having 3 children who are all girls is ¼ because there can be 0 girls, 1 girl, 2 girls or 3 girls.

Aimee designs a simulation to test her prediction. She flips a coin 3 times in a row and records the results. She uses heads to represent a girl and tails to represent a boy. After 10 trials of this simulation, Aimee gets the following results.

1 2 3 4 5 6 7 8 9 10
BBB GBB GGG GGB BBG GGB BGG BGB BBG GBB

Does ¼ seem like a reasonable probability of having 3 girls? Use a tree diagram to model and support your thinking.
Estimate the probability of having 3 girls using the results from Aimee’s simulation.

Answer:

28650

Step-by-step explanation:

just subtract 59,466-30,816

The number of more people who live in Cheyenne than in Laramie given the population of each city in the state is 28,650 people

Population can be defined as the total number of people living in a particular geographical location at a period of time.

Population of Cheyenne = 59,466

Population of Laramie = 30, 816

The number of more people who live in Cheyenne than in Laramie = Population of Cheyenne - Population of Laramie

= 59,466 - 30, 816

= 28,650 people

Hence, 28,650 more people live in Cheyenne than in Laramie.

Exact form: -33/8

Decimal form: -4.125

Mixed number form: -4 1/8

Answer:

$24

Step-by-step explanation:

To begin we need to form an equation that equals the total amount of money, which is 56. The question tells us that Anitha's money and Jyothi's money comes to a sum of $56 (the total amount). So, in our equation we will be doing Anitha + Jyothi = 56; our equation will be 4x+2x+8=56.

The next step is to rearrange the equation to get x=..., and we can do this using the funnel method like I have shown in the attached image. First, I simplified to get 6x+8=56. Then, I subtracted 8 from both sides to get 6x=48. Finally, I divided by 6 on both sides to get x=8. This is the first step of the question completed.

The finish the question, we need to work out Jyothi's total money, and since we now know x=8, all we need to do is substitute 8 where x is for Jyothi. So, we need to calculate the answer to 2*8+8, and following the rules of BIDMAS, we get 24. Which is the final answer.

Answer:

y = 2x + 2

Step-by-step explanation:

As we know, slope intercept is: y = mx + b

m is slope and b is the y-intercept.

Looking at this problem, we can see that the line crosses the y-axis at positive 2, so that is our y-intercept. For the slope, take a point like the y-intercept, and see how many squares is has to go up before it reaches the next square to the right. In this problem the line goes up 2 squares in the time it takes to go to the right 1. So the slope is y over x, or 2 over 1, or just 2.

Answer:

152%

Step-by-step explanation:

There are 50 small squares total, 25/25 are filled in for the 1st big square, and 13/25 filled in for the 2nd big square.

25/25 + 13/25 = 1.52

1.52 * 100 = 152%

Sila put a wrong number in her calculator

Sila jogged 12 kilometers today and wants to know how far she traveled in feet. What error did Sila make while converting from kilometers to feet ? The correct answer is Option a) Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction = 392,832 feet.

Sila's mistake can be identified in her conversion calculation. She first needs to convert kilometers to miles and then miles to feet. Let's break down the process step by step:

1. Kilometers to Miles:

Start by converting kilometers to miles.

There are 0.62 miles in 1 kilometer.

So, the first fraction is correct:

Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction.

2. Miles to Feet:

Next, convert miles to feet.

There are 5280 feet in 1 mile. Sila's calculation is incorrect at this step. The correct fraction to use here is Start Fraction 5280 feet Over 1 mile End Fraction.

Now, let's put it all together:

- Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction

Multiply the fractions step by step:

- 12 kilometers * 0.62 miles/kilometer * 5280 feet/mile

- This simplifies to 392,832 feet.

So, Sila's error lies in not using the correct conversion factors for both kilometers to miles and miles to feet.

The correct conversion factors should be applied in sequence, leading to the final answer of 392,832 feet traveled.

Answer: 34

Step-by-step explanation:

therefore, the answer to "17 is 50 percent of what number?" is 34, and you can also derive that 50 percent of 34 equals 17

Answer:

34

Step-by-step explanation:

This is a fairly simple problem. If 17 is 50% of something, that means it's half of something. That means to multiply 17 times 2, and you get 34.

2/15

Further explanation

For the problem:

1/5 times 2/3

Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

1 × 2

5 × 3

=

2/15

The result is:

1/5 × 2/3=2/15

He made an error in step 1. Specifically, he distributed incorrectly.

The 3(x+2) portion is not the same as 3x+2. We need to multiply that '3' by the 2 as well to get 3*2 = 6

In other words, 3(x+2) should turn into 3x+6

If you wanted, you can think of 3(x+2) as three copies of (x+2) added together like this:  (x+2)+(x+2)+(x+2) = (x+x+x)+(2+2+2) = 3x+6
