Option c
Step-by-step explanation:
The study is an observational study. An observational study is made when the researchers collect data based on what they see, hear or observe without any form of manipulation or treatment plan from the researchers. Thus, in this case, the study is an observational study because the study examines individuals in a sample, but does not try to influence the response variable/influence their responses.
Answer:
neither even not odd
Step-by-step explanation:
A function is odd if and only if y=f(x) is the same as y=-f(-x). Also a function is said to be even if and only if y=f(x) is the same as y=f(-x).
given our function f(x)=4x^5+8x+2
-f(-x)=-(4(-x)^5+8(-x)+2)
=4x^5+8x-2
also,
f(-x)=4(-x)^5+8(-x)+2
=-4x^5-8x+2
from the above we see that f(x) ≠ -f(-x) and also f(x) ≠ f(-x). We therefore conclude that the function is neither even not odd
Answer: 35,476.69
Step-by-step explanation:
the formula is
A=p×e^(rt)
A future value?
P present value 25000
R interest rate 0.07
T time 5years
A=25,000×e^(0.07×5)
A=35,476.69
Hope it helps!
