Y= 12*x
Y=12x
In short, y is a product of 12 and x
<span>What
is $22 marked up to $33
Ok, let us first analyze the given problem.
=> 22 dollars is said to be the original amount of money.
=> 33 dollars is the total marked up amount.
Now, we need to find out how many percent did the money increased
Solutions:
=> 33 dollars - 22 dollars = 11 dollars
=> 11 dollars / 22 dollars = 0.5 dollars
=> 0.5 dollars * 100% = 50%
Thus, the marked up money is 50%

Answer:
C. ( x - 14 )2 + ( y - 9 )2 = 13
Step-by-step explanation:
Answer: d × 4 = D
Step-by-step explanation: d= days and D= dollars
Answer:
Yes
Step-by-step explanation:
The central limit theorem says that If a random variable X from a population has mean u and finite variance σ² , then the sampling distribution of the sample mean X~ approaches a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.
It is interesting to note that we have neither assumed that the distribution of X is continuous nor we have said anything about the shape of the distribution , whereas the limiting distribution of X is continuous and normal. Thus the distribution of the sample means regardless of the shape of the population having a finite variance , is approximately normal with mean u and variance σ²/n .
Therefore
(standard deviation/ √sample size)²= variance / n
2/ √20
= 2/4.472
=0.44721
The sampling distribution of X` is therefore approximately normal with mean ux=u and σx =σ/n
