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
I don't see y or z in the problem, but I know that X=4
Answer:
4x + 15
Step-by-step explanation:
Let the age of Khairul's uncle y.
From the question given above, the following were obtained:
Khairul's age = x years
In 5 years time:
Khairul's age = x + 5
Khairul's uncle age = y + 5
But from the question given above,
Khairul`s uncle will be 4 times as old as what khairul will be in 5 years. This can be written as follow:
y + 5 = 4(x + 5)
Clear bracket
y + 5 = 4x + 20
Subtract 5 from both side
y + 5 – 5 = 4x + 20 – 5
y = 4x + 15
Therefore, Khairul's uncle present age is 4x + 15
