Answer:
Step-by-step explanation:
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process, and each subset of k individuals has the same probability of being chosen for the sample as any other subset of k.
Answer:
a = 132 ft^2
Step-by-step explanation:
Area of triangle
a = (1/2)bh
---------------------------
Base
a = (1/2)(8)(6)
a = 24 ft^2
----------------------
Each side
a= (1/2)*(8)(9)
a = 36
All three sides
a = 36 * 3
a = 108 ft^2
-----------------------
Total area
a = 24 + 108
a = 132 ft^2

Step-by-step explanation:
Answer: last option (5π√146 units²)
Step-by-step explanation:
To solve the exercise you must apply the formula for calculate the lateral area of a cone, which is shown below:
where r is the radius but L is the slant height.
As you can see in the figure attached:
But you need to find the slant height with the Pythagorean Theorem (L would be the hypotenuse):
Substitute into the formula, then:
units²
