Given Information:
The proportion of electric cars sold in 2012 = p₁ = 0.1%
The proportion of electric cars sold in 2016 = p₂ = 0.5%
Sample size of electric cars in 2012 = n₁ = 10,000
Sample size of electric cars in 2016 = n₂ = 20,000
Confidence level = 95%
Required Information:
Change in the proportion of electric cars sold from 2012 to 2016 = ?
Answer:
Change in the proportion of electric cars sold from 2012 to 2016 = (0.284%, 0.516%)
Step-by-step explanation:
The change in the mean is given by

The change in standard error is given by

Where z is the value of z-score corresponding to 95% confidence level.


The change in the proportion of electric cars is

Therefore, we are 95% confident that the change in the proportion of electric cars sold from 2012 to 2016 is between (0.284%, 0.516%)
Answer:
(-5, - 4) ;
(4, - 5) ;
(5, 4)
(-4, 5)
Explanation:
Given : (x, y)
90° counterclockwise rotation = (-y, x)
180° clockwise rotation = (-x, - y)
270° counterclockwise rotation = (y, - x)
270° clockwise rotation = (-y, x)
Using the translations started above :
Point(5, 4) rotated 180° clockwise - - - > (-5, - 4)
Point(-5, -4) rotated 90° counterclockwise - - - - - - - > (-(-4), - 5) - - - > (4, - 5)
Point(-4, 5) rotated 270° counterclockwise - - - > (5, - (-4)) - - - > (5, 4)
Point (5, 4,) rotated 270° clockwise - - - > (-4, 5)
