You reduce similar terms ("n" and numbers) then you just simplify the equation and kind of guess the even numbers that equal 42 based on your answer (12)

A reseacher wants to collect a sample to learn more about the wild lemur population in Madagascar. According to this, the true statement is the reseacher can assign each lemur a number and then use a systematic sampling (option A).
Systematic sampling is a form of sampling characterized by choosing the sample at random. According to the above, random sampling is the best option for the researcher.
It is not easy to study the entire population of lemurs in Madagascar, therefore systematic sampling is ideal. In this way, the researcher can sample a few lemurs and using this probability method can draw conclusions.
According to the above, the correct answer is A. because it presents information corresponding to the situation presented.

Answer:
a) t = 4 secs
b) t = 3 secs
Step-by-step explanation:
h = 64 ft
Initial velocity = 48 ft/s
S = 64 + 48t - 16t^2
a) Set S = 0 and solve for t
0 = 64 + 48t - 16t^2
Divide through by 16
0 = 4 + 3t - t^2
t^2 - 3t - 4 = 0
t^2 - 4t + t - 4 = 0
t(t - 4) + 1(t - 4) = 0
(t + 1) (t - 4) = 0
t + 1 = 0 or t - 4 = 0
t = -1 or t = 4
t = {-1,4}
t = 4 seconds
b) Set S = 64 and solve for t
64 = 64 + 48t - 16t^2
64 - 64 = 48t - 16t^2
0 = 48t - 16t^2
Divide through by 16
0 = 3t - t^2
t^2 - 3t = 0
t(t - 3) = 0
t = 0 or t-3 = 0
t = 0 or t = 3
t = {0,3}
t = 3 secs
