Answer:
62%
Step-by-step explanation:
Given the information :
224 visitors purchased no costume.
103 visitors purchased exactly one costume.
32 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.
Probability that next person will purchase no custome:
Probability = no of successes / total number of trials
Total number of trials :
(purchase no custome + purchase exactly one + purchase more than one)
= (224 + 103 + 32) = 359
Hence, Probability that next person will purchase no custome:
= 224 / 359
As a percentage :
(224 / 359) * 100%
= 0.6239554 * 100%
= 62.39 %
= 62% ( nearest whole percent)
The place value of decimal number given as 209.45 is two decimal places
<h3>How to determine the
place value?</h3>
The decimal number is given as:
Number = 209.45
The place value implies that the number of significant digits after the decimal point
In the given number 209.45, there are 2 significant digits after the decimal point i.e. 4 and 5

<h3>
Answer: 13 pens</h3>
=========================================================
Explanation:
Roy spends 1/4 of his money on 3 pens and 6 notebooks. That means 3/4 of it is leftover.
2/3 of 3/4 = (2/3)*(3/4) = 1/2 of his money is spent on buying some unknown number of additional pens. We'll come back to this later.
---------------
In terms of cost,
1 pen = 3 notebooks
which is another way of saying 1 pen is the same price as 3 notebooks.
Multiply both sides by 2 to get
2 pens = 6 notebooks
Therefore, saying "3 pens + 6 notebooks" is the same as "3 pens + 2 pens = 5 pens" when just thinking about costs.
---------------
In short, Roy buying 3 pens and 6 notebooks is the same as him buying 5 pens. He spends 1/4 = 25% of his money on getting these 5 pens.
Multiply those two values by 2 to find that 50% = 1/2 of his money would allow him to get 10 pens.
--------------
Recall that at the end of the first section, we concluded that Roy spent 1/2 of his money on buying those unknown additional number of pens. Then the previous section mentioned that 1/2 of his money gets him 10 pens. Therefore, he must have bought 10 additional pens on top of the original 3 mentioned in the instructions.
Overall, he purchased 3+10 = 13 pens
I believe it is D.
On the very bottom if you just go straight across then it would be 7+3+8 which is 18.
