Answer:
c) gives each member of the population a known chance to be selected
Step-by-step explanation:
A sample is said to be a probability sample when each and every unit of the population would have the known chance or the probability i.e. more than zero when selected in the sample
So according to the given options, it is the sample where each member have the known chance to be selected
Therefore the option c is correct
All real numbers or is it multiple choice
D is the answer. Keep in mind that the absolute value of a number is always positive
We will first find the volume of the base:
V 1 = 9² · 5 = 81 · 5 = 405 in³
Then the volume of the upper solid - pyramid. We must find the height of the pyramid:
h² = 11² - 4.5² = 121 - 20.25 = 100.75
h = √100.75
h = 10.037429
V 2 = 1/3 · 9² · 10.037429 = 271.01
Finally, the volume of the composite solid:
V = V 1 + V 2 = 405 + 271.01 = 676.01
Answer: C. 676.01 in³
