Fran cut her sandwich into 6 pieces. If Fran ate 1/3 of her sandwich, how many pieces did he eat?

Answers

2 pieces :)

Not sure if you wanted work but here is my explanation:

there are six pieces that she cut out, and she ate 1/3 of the six pieces,

1/3=2/6

since there are 6 pieces 1/3 would then equal 2 pieces. :)

Hope this helps:)

2 because 1/3 is equal to 2/6

PLEASE HELP! WILL CHOOSE THE BRAINLIEST ANSWER!!Mark has 100 blue marbles, 34 red marbles, and 98 green marbles. After pulling out 6 blue marbles, 3 green marbles, and 1 red marble, he add's 20 pink marbles. What is the probability that he will pull out a pink marble?

Answers

Mark started out with 232 marbles in the bowl. He pulled out 10 of them, leaving 222 marbles in the bowl. Then he added some. Now there are 242 marbles in the bowl, and 20 of them are pink. The probability that his next pull will be a pink one is 20/242 = about 8.3 percent.

The probability of Mark pulling out a pink marble is approximately 0.083 or 8.3%.

To find the probability of pulling out a pink marble, we need to know the total number of marbles Mark has after making the changes described in the problem.

Mark started with a total of 100 + 34 + 98 = 232 marbles.

After pulling out 6 blue, 3 green, and 1 red marble, he has 100 - 6 = 94 blue marbles, 34 - 1 = 33 red marbles, and 98 - 3 = 95 green marbles left. This means he has a total of 94 + 33 + 95 = 222 marbles.

When he adds 20 pink marbles, his total number of marbles becomes 222 + 20 = 242.

So the probability of pulling out a pink marble is:

Number of pink marbles / Total number of marbles = 20/242 ≈ 0.083

Therefore, the probability of Mark pulling out a pink marble is approximately 0.083 or 8.3%.

Which number would you put in a frequency table to show 8

Answers

well 2x4 would = 8 so you would have to put 2 and 4

Final answer:

A frequency table lists numbers and their occurrences within a set of data. If '8' shows up in your data, you would put it in the frequency table alongside the number of times it appears.

Explanation:

A frequency table is a helpful tool in statistics. It's a type of tally chart that shows how often different numbers or items occur in a set of data. If the number '8' appears in your data, you would place it in the frequency table alongside the number of times it appears.

For example, if the number '8' appeared three times in your data, your frequency table might look something like this:

Number: 8
Frequency: 3

This shows that the number '8' has a frequency of 3 in your data set.
