Answer:
Snowball Sampling
Step-by-step explanation:
Based on the specific scenario that is being described it can be said that the best type of sampling for you to use would be Snowball Sampling. This is a unique nonprobability sampling technique where subjects for the experiment at hand are recruited from the existing subjects list of acquaintances. Such as in this case it would target all the acquaintances of the Sting-Ray owners.
Answer: $169,500
Step-by-step explanation:
The mean simply means the average price of a set of a numbers that are given. For one t calculate the mean, one has to add the numbers that are given and then divide them by the amount of numbers.
I'm the case above, the numbers given are $165,000, $188,000, $175,000, and $150,000.
Mean = ($165,000 ,+ $188,000 +$175,000 + $150,000) ÷ 4
= $678,000/4
= $169,500
The initial velocity of the fish is the same as that of the pelican and it is -0.50 m/s. The distance traveled by the object is given by the equation,
d = (V1)t + 0.5at²
where t is equal to 2.50s and the acceleration due to gravity, a, is 9.80 m/s². Substituting,
d = (-0.50 m/s)(2.5 s) + 0.5(9.8 m/s²)(2.50 s)²
d = 30.625 m
Thus, the answer is letter C.
