Answer:
Coordinates of A prime will be (-4,0).
Step-by-step explanation:
Given:
ABC is a triangle on a grid with its coordinates in (x,y).
The coordinates are as follows:
According to the question.
The points are translated by (x-2,y+2) rule.
We have to find A prime i.e A' the coordinate of A after it is translated.
In translation we move the coordinates without rotating and resizing.
So
Point A after translation will be called A'.
⇒ A =
Subtracting 2 with the 'x' value and adding 2 with the 'y' value coordinate.
⇒ A' =
⇒ A '=
So the value of A prime after translating it by (x-2,y+2) is (-4,0).
The sample standard deviation is used to calculate the determine the spread of estimates for a set of observations (i.e., a data set) from the mean (average or expected value).
<h3>What is sample standard deviation?</h3>The spread of a data distribution is measured by standard deviation. The average distance between each data point and the mean is measured.
The sample standard deviation (s) is a measurement of the variation from the expected values and is equal to the sample variance's square root.
where
s = sample standard deviation
N = the number of observations
= the observed values of a sample item
= the mean value of the observations
