Answer:
B: A systematic random sample
Step-by-step explanation:
Systematic sampling is a type of probability sampling in which members of a larger population are chosen at random from a larger population but at a fixed, periodic interval. This interval, also known as the sampling interval, is calculated by dividing the population size by the sample size desired. Despite the fact that the sample population is chosen in advance, systematic sampling is still considered random if the periodic interval is set in advance and the starting point is chosen at random.
Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?
First we would find the area of the entire thing,
A=1/2(base)(height)
so A = 1/2(5)(12) = 30 mm^2
next we find the area of the smaller triangle,
A = 1/2(4)(3) = 6 mm^2
Then we subtract the area of the smaller triangle from the area of the larger one
30-6 = 24 mm^2
Answer:
Step-by-step explanation:
Rewrite the equation using the next propierties:
Cancel logarithms by taking exp of both sides:
Multiplying both sides by -x and factoring:
Factoring:
The solutions are:
Evaluating x=-4
This is an absurd because ln(x) is undefined for 
Evaluating x=-1
Which is correct, hence the solution is:
Answer: $5.85
Explanation: 1.8 x 3.25 = 5.85
Step-by-step explanation:
The answer is 45 square root of 110.
