Complete question :
A taxi driver records the time required to complete various trips and the distance for each trip. The best fit line is given by the equation y = 0.467 x + 0.417 where y represents the distance in miles, and x represents the time for the trip in minutes. Use the best fit line to estimate the distance for a trip that takes 20 minutes.
Answer:
9.757 miles
Step-by-step explanation:
Given the model Equation:
y = 0.467x + 0.417
y = predicted distance in miles
x = trip time in minutes
The distance for a trip that takes 20 minutes
Substitute 20 for X in the best fit equation
y = 0.467(20) + 0.417
y = 9.34 + 0.417
y = 9.757
Hence, distance in miles for a 20 minutes trip is 9.757 miles
Answer:
Cost of One Journal = $3.99
Cost of One pen = $0.59
Step-by-step explanation:
Let
Cost of One Journal = x
Cost of One pen = y
We can make equation from given statements.
Mr. Bowden purchases 18 journals and 40 pencils for $95.42.
Ms. Jacinto purchases 11 journals and 16 pencils for $53.33.
Now solving these equations to find the value of x
Multiply eq(1) with 2 and eq(2) with 5
We get the value of x is: x=3.99
Now, putting value of x in equation 1 to find value of y.
So, we get the value of y: y = 0.59
Now, finding the costs:
Cost of One Journal = x = $3.99
Cost of One pen = y = $0.59
Answer:
43100
Step-by-step explanation:
A rectangular one-story house covers an area of 3,700 square feet. The ceilings are 8 feet high. The owners add a second floor to the house. The second floor is 50 feet long and 30 feet wide with ceilings that are 9 feet high. What is the total volume of the interior of the house?
Volume = length x width x height
or volume = area x height
Volume of the one- storey = 3700 x 8 = 29600 square feet
Volume of the second floor = 50 x 30 x 9 = 13500 square feet
volume of interior = 29600 + 13500 = 43100 square feet
