In the case of Irina shown below, the rule for this translation that is best is T-3, 2(x, y).
<h3>What is the translation about?</h3>Note that we know that the tile floor is said to be shifted or moved to the left hand side by 3 units, and also it was moved up by 2 units (See image).
Therefore, this can be shown as:
(x,y) -> (x - 3, y + 2)
This in another method can also be written as:
T -3,2 (x,y)
Therefore, we can say that the translation rule is T -3,2 (x,y)

Answer:
And we can find the following probability:
And the last probability can be founded using the normal standard distribution or excel.
Step-by-step explanation:
For this case we define the random variable X as the ages of vehicles. We know the following info for this variable:
represent the mean
represent the deviation in years
They select a sample size of n=40>30. And they want to find this probability:
Since the sample size is large enough we can use the central limit theorem and the distribution for the sample mean would be:
We can use the z score formula given by:
And if we find the z score for 4 we got:
And we can find the following probability:
And the last probability can be founded using the normal standard distribution or excel.
