Answer:
36 degrees.
Step-by-step explanation:
Total Sum of the Exterior Angle of a Regular Polygon
One Exterior Angle of a n-sided regular polygon
A decagon has 10 sides.
One Exterior Angle of a decagon
Therefore, the measure x of the angle between the house and the pool is 36 degrees.
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.
