X equals to 3
27 times 3 is 81 and 9 times 3 is 27
Answer:
The equivalent expression would be 3^6, and without exponents this would be equal to 729.
Step-by-step explanation:
To get the equivalent expression, you have to know that terms with the same base that are multiplied simply add together exponents.
3^4 * 3^2 = 3^6
Then we can find that by expanding the terms and completing the multiplication.
3 * 3 * 3 * 3 * 3 * 3 = 729
Answer:
2n+500+2(2n+500) -500
Step-by-step explanation:
Using sampling concepts, it is found that this is an example of a random sample.
<h3>How are samples classified?</h3>
Samples may be classified as:
- Convenient: Drawn from a conveniently available pool.
- Random: All the options into a hat and drawn some of them.
- Systematic: Every kth element is taken.
- Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
- Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.
In this problem, one winner is chosen at random from all the participants, hence random sampling is used.
