Answer:
y=12/x
Step-by-step explanation:
if y=12, and x=1 so
general formula y=12/x
for x=5 , y=12/5=2.4
you can graph by ploting points such as (1,12), (5, 2.4),...
The outlier, 78, is removed from the data set shown. 23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78 How does this affect the range?

Hello.
The range with 78 is 55
without 78 is 22
So the range goes down
Have a nice day
Length of the walkway that needs to be tiled = 60 feet
Width of the walkway that needs to be tiled = 2 feet.
Then
Area of the walkway that needs to be tiled = Length * Breadth
= 60 * 2 square feet
= 120 square feet
Now
Length of the tiles sold by the local store = 2 feet
Width of the tiles sold by the local store = 2 feet
Area covered by the tiles sold by the local store = 2 * 2 feet
= 4 square feet
Number of tiles in a box = 6
Then
Total area covered by a box of tile = (6 * 2) square feet
= 12 square feet
Then
The number of boxes required by Sean = (120/12)
= 10
So 10 boxes of tiles are needed by Sean and his father.
The number of days that Aubrey can drive to stay in her budget is 5 days.
<h3>Inequality signs and their meanings</h3>
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
<h3>Equation that represents the question</h3>
Total amount that can be spent ≤ (cost to rent a car per day x number of days) + (cost per mile x total miles driven)
$130 ≤ ($22.15 x dd) + ($0.07 x 275)
<h3>Determination of the number of days that Aubrey can drive</h3>
130 ≤ ($22.15dd) + ($0.07 x 275)
130 ≤ $22.15dd + 19.25
130 - 19.25 ≤ $22.15dd
110.75 ≤ 22.15d
d ≤ 110.75 / 22.15
d ≤ 5

Hello!</h2>
The answer is:
The correct option is:
A. $0.49
<h2>
Why?</h2>
From the statement, we know that the iHome is used on average three hours a day, and we are asked to find the cost for a week, so first, we need to calculate the total hours that the iHome is used for, and then, calculate the kilowatt-hour consumption rate.
![TotalTime_{week}=3\frac{hours}{day} *7days=21hours](https://tex.z-dn.net/?f=TotalTime_%7Bweek%7D%3D3%5Cfrac%7Bhours%7D%7Bday%7D%20%2A7days%3D21hours)
![TotalEnergyConsumption_{week}=180watt*21hours=3780watt.hour](https://tex.z-dn.net/?f=TotalEnergyConsumption_%7Bweek%7D%3D180watt%2A21hours%3D3780watt.hour)
Now, we must remember that:
![1Kilowatt=1000watts](https://tex.z-dn.net/?f=1Kilowatt%3D1000watts)
So,
![3780watts=3780watts.hour*\frac{1KiloWatt}{1000watts}=3.78KiloWatt.hour](https://tex.z-dn.net/?f=3780watts%3D3780watts.hour%2A%5Cfrac%7B1KiloWatt%7D%7B1000watts%7D%3D3.78KiloWatt.hour)
Then, calculating the cost, we have:
![TotalCost_{week}=0.13\frac{dollar}{killowat.hour}*3.78killowat.hour=0.49(dollar)](https://tex.z-dn.net/?f=TotalCost_%7Bweek%7D%3D0.13%5Cfrac%7Bdollar%7D%7Bkillowat.hour%7D%2A3.78killowat.hour%3D0.49%28dollar%29)
Hence, we have that the correct option is:
A. $0.49
Have a nice day!
