Answer:
x=10.5
Step-by-step explanation:
5(x+3)=(6)(12)-[.5(6)(12-x)]
5x+15=72-36+3x
reduce
2x=21
x=10.5
check
5(10.5+3)=(6)(12)-[.5(6)(12-10.5)]
52.5+3=72-4.5
reduce
67.5=67.5
Divide total dollars by total pounds:
$35 /5 = $7 per pound
Answer: $7
Answer:
C)Systematic Random Sample
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this case:
Every kth element(in this exercise 10th) is systematic sample. So the answer is given by option c.
