8, 32, 128
OR
-8, 32, -128
Answer:
I do 1 option for you as an example, you need to check the leftover by yourself.
Step-by-step explanation:
for d) y(0) = 0 and y'(pi) =0



Replace
we have
if and only if 
Hence the given solution does not work.
then, d is NOT the correct answer.
The answer is option C:
<span>A line of symmetry will connect a vertex and a midpoint of an opposite side.
It has 7-fold symmetry.</span>
Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-

Given : Sample size :
, which is a large sample , so we apply z-test .
Sample mean : 
Standard deviation : 
Significance level : 
Critical value : 
Now, a confidence interval at the 95% level of confidence will be :-
