When Stephan moved from Illinois to Florida, his average monthly electric bill increased from $83 to $102. He is curious to know

kondaur [170]

Answer: The z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.

Step-by-step explanation:

Given: Average monthly electric bill in Illinois = $83

Average monthly electric bill in Florida = $102

Formula of z : $z=\dfrac{X-mean}{standard\ deviaton}$

In Illinois, the mean monthly electric bill is $85, with a standard deviation of $3.20.

$z=\dfrac{83-85}{3.20}= -0.625$

In Florida, the mean monthly electric bill is $105, with a standard deviation of $4.00.

$z=\dfrac{105-102}{4}=\dfrac{3}{4}=0.75$

Hence, the z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.

Point A is located at (3, 4) and is translated right five units and down three units. What is the new location of point A?

lubasha [3.4K]

Answer is (8,1)
x axis which is 3 originally is shifted by 5 units to the right so it becomes (3+5 =8)
y axis which is 4 originally is shifted by 3 units downwards ( in negative direction) so it becomes (4-3 = 1)
therefore point is translated to (8,1)
