Mr. Dotson wants to know if the neighbors on his street would be interested in a community watch. He surveys every fourth household and concluded that 70% would be interested

The answer is "This is true since it is a random systematic  sample".

Step-by-step explanation:

In the given scenario, Systemic random sampling involves the random sampling method which often involves the collection of samples onto an interval system in such a numbered group of people based on the premise/base. It also is a selection of samples at a particular preset interval.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

5x+10 is the correct one

hope this
