Answer:
You are correct the answer is 48.
Step-by-step explanation:
To begin solving this question you would want to start simplifying it to make it more understandable.
3^3 is 27 which now gives you 27 + 1 x 9 +12 which makes it easier to solve.
Then you would take 1 x 9 = 9 (multiply left to right)
Now it is simple addition
27 + 9 + 12 = 48
Hopefully this helps.
Answer:The answer is Equal.
Step-by-step explanation:First you need to add A and 2A together. that equals 3a. Since 3 is left , it could be -1 and 4 because it would equal the same thing hope this helped :)
Answer:
a) 
b) The should sample at least 293 small claims.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so , which means that the answer of question a is z = 1.645.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
(b) If the group wants their estimate to have a maximum error of $12, how many small claims should they sample?
They should sample at least n small claims, in which n is found when
. So
The should sample at least 293 small claims.
I am pretty sure R is -19 meters and N is -7 and A is 476 AD
Answer:
C
Step-by-step explanation:
The tosses before that were all by chance, the probability is still the same. Nothing changes.
