87; If he gave two thirds of his remaining cards to Elaine, then he had one third left. If one third of his remaining cards is 25, then 25 x 3 will give you what he had after trading with Tommy. When he finished trading with Tommy he had 75 cards. if he gave away 15 cards, but got three back, then he must have had 87 cards to begin with.
Check your answer:
87-15 = 72
72+3 = 75
2/3 of 75 = 50
75-50 = 25

Answer:
<h2>It is Random sampling.</h2>
Step-by-step explanation:
There are total 5 types of sampling.
- Random Sampling: In this kind of sampling, elements are randomly chosen from a particular population. Every elements of the population carries the same probability in this case.
- Systematic Sampling: Every k-Th element is taken for this kind of sampling.
- Convenience Sampling: Here samples are chosen as per the accessibility.
- Cluster Sampling: First the whole population is divided in some groups or cluster, then some groups are randomly selected.
- Stratified Sampling: The whole population is being divided into groups as per some characteristic. Then from each group, one sample is to be chosen either randomly or using some other process.
Since, in the given question the students are chosen randomly, Random sampling is being used here.
An absolute value inequality that represents the acceptable amounts of sodium is; 35 ≤ A ≤ 45
<h3>What is the Absolute Value Inequality?</h3>
We are told that a can of soda can have a minimum of 35 milligrams of sodium and a maximum of 45 milligrams of sodium.
Now, an absolute value inequality that represents this expression would be written as;
35 ≤ A ≤ 45
Thus, we conclude that an absolute value inequality that represents the acceptable amounts of sodium is; 35 ≤ A ≤ 45
