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).
A scale map is not an actucal size its a small size we can see
The actual answer is 5.66666666
The reason is that because he made 238 over 42 months you divide 238$ by 42 months

Complete Question
A survey is planned to estimate the proportion of voters who support a proposed gun control law. The estimate should be within a margin of error of ±5% with 90% confidence, and we do not have any prior knowledge about the proportion who might support the law. How many people need to be included in the sample?
Round your answer up to the nearest integer.
sample size = _____
Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The margin of error is E = 5% = 0.05
Generally given that there was no prior knowledge about the proportion of who might support the law, we will assume the sample proportion to be
From the question we are told the confidence level is 90% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%5C%5E%20p%20%281%20-%20%5C%5E%20p%20%29%20)
=> ![n = [\frac{1.645 }{0.05} ]^2 * 0.5 (1 - 0.5 )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B1.645%20%7D%7B0.05%7D%20%5D%5E2%20%2A%200.5%20%281%20-%200.5%20%29%20)
