Step-by-step explanation:
The answer is C. Systemic random sampling.
By definition, systemic random sampling is a sampling technique where the respondents are selected according to a <em>random starting point </em>(this alone shows that the answer is C.) The researcher then chooses the sample interval, which is the difference between two consecutive numbers in the progression.
In this case, the starting point is 8 and the sample interval is 10.
The answer is C.

Step-by-step explanation:
Given
The given proportion can be represented as:
Required
The additional number of mulch needed
The question has incomplete details, as the amount of mulch he has applied and the area of the flower garden are not given.
So, I will make some assumptions to solve this question.
Let the area of his flower garden be x.
So, we have:
Cross multiply
Make y the subject
--- This represents the total amount of mulch required for the flower garden

<u>Assumptions</u>
Assume that ,
So, we have:
i.e 4 bags are needed.
Assume he has applied 2 bags already.
The number of bags needed to apply will be:
<em>2 more bags needed</em>

Answer:
The distance of Jack's Father's work from home in miles is 45 miles.
Step-by-step explanation:
a) Data and Calculations:
Normal time taken by Jack's father to drive to work = 30 minutes
Time taken when traffic is bad = 1 hour longer
Speed when traffic is bad = 30 mph slower
Distance covered when traffic is bad, with time taken as 1 hour 30 minutes = time * speed = 1.5 * 30 = 45 miles
b) Jack's father normally drives at 90 mph (45 *2), this is why it normally takes him 30 minutes between his home and workplace when the traffic is not bad. However, when traffic is bad, it takes him one hour longer and he drives at 30 mph slower.
