Answer:
5 students would be expecting to select a gold-wrapped candy from the bag.
Step-by-step explanation:
Since Mrs. Nickel puts a variety of wrapped chocolate candies in a bag, and there are 5 silver-wrapped candies, 1 purple-wrapped candy, 2 striped candies, and 4 gold-wrapped candies, if 15 students select one candy at a time out of the bag, without looking, and replace the candy after each draw, to determine how many students would be expecting to select a gold-wrapped candy from the bag, the following calculation must be performed:
5 + 1 + 2 + 4 = 12
4 gold-wrapped candies out of 12 in total
4/12
15 x 4/12 = X
15 x 0.333 = X
5 = X
Therefore, 5 students would be expecting to select a gold-wrapped candy from the bag.
Step-by-step explanation:
Write down the larger number. ...
Write the smaller number directly below it. ...
Subtract the number in the ones column of the bottom number from the number in the ones column of the top number. ...
Subtract the number in the tens column of the bottom number from the number in the tens column of the top number.
If you have more columns then continue with this step
*when subtracting you sometimes have to regroup
what is regrouping?
Regrouping in math is a term used to describe the process of changing groups of ones into tens to make adding and subtracting easier. In addition, you regroup when the numbers you are adding come out to two digit numbers if they are not in the furthermost left column.
how to regroup:
Subtract 1 from the top number in the column directly to the left. Cross out the number you're borrowing from, subtract 1, and write the answer above the number you crossed out.
Add 10 to the top number in the column you were working in.
