Answer:
A. x = 7
B. x = -3
Step-by-step explanation:
A. 5/x = 30/42
5/x = 5/7
5 = 5/7 x
5= 5x/7
5 x 7 = 5x
35 = 5x
35/5 = x
7 = x
x = 7
B. x/8 = -12/32
x/8 = -3/8
x = - 3/8 x 8
x = - 24/8
x = -3
Hope this helps you have a gr8 day :3
Using sampling concepts, it is found that the correct option is:
This is a convenience sample and likely overestimates support for raising funds.
<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, people at the pool were surveyed, hence it is a convenience sampling.
Also, since it only involved pool users, the proportion may be overestimated, hence the correct option is:
This is a convenience sample and likely overestimates support for raising funds.

Out of 80 students, 52 will attend
80/52 = 1600/ x
x=1040
So when you have a -(-) then you make that a positive so that would mean - (+) so the two - - are positive and just one - is still negative, which would mean that the answer is -3. Because if the negative is greater that the positive then it is still a negative, in your mind you should make 13 positive minus 10 and then add the negative to make things easier if you want to.
