Answer:
4
Step-by-step explanation:
Evaluate f(3) and g(2)
f(3) = 2(3) - 4 = 6 - 4 = 2
g(2) = - 3(2)² + 5(2) = - 3(4) + 10 = - 12 + 10 = - 2
Then
f(3) - g(2) = 2 - (- 2) = 2 + 2 = 4
Answer:
D. It is the method that is most likely to give a true representative sample.
Step-by-step explanation:
The advantage of selecting a random sample is that is without bias, so being a true representative sample.
For example, if you want to estimate the proportion of the population of a certain city that is going to vote for a candidate in the elections, you must select at a place where different people passes, not one uniform place like a school, just a simple example.
So the correct answer is:
D. It is the method that is most likely to give a true representative sample.
Answer:
Step-by-step explanation:
Each y is 3 times the last one, so it's geometric, so exponential. 3 should appear as the base.
Answer:
70 degrees.
Step-by-step explanation:
They are vertical angles, and vertical angles are always congruent.
