Answer:
the second choice
Step-by-step explanation:
Answer:
(c) 118/V100 11.8
Step-by-step explanation:
We use the central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation 
In this problem, we have that:

So

So the correct answer is:
(c) 118/V100 11.8
5x+3y+6x+9y
All you'd need to do is combine like terms. So add 5x to 6x and add 3y to 9y.
(5x+6x)+(3y+9y)
Final Answer: 11x + 12y
Answer:
53=-3+14d
56=14d
d=4 that is the common difference
