Fueleconomy.gov gives the city and highway fuel economy for all makes and models of vehicles back to 1984. The table
gives the city and highway fuel economy (mpg) for a random sample of ten 2021 vehicles
a. Find the equation of the LSRL. Write it below.
b. Find and interpret s.
C. Find and interpret the value of m2
Answers
The equation of the Least Square Regression Line which models the data for the city and highway fuel economy and interpreted values of it's parameters are :
Ŷ = 1.264X + 6.084The slope, s = 1.264, per unit increase in miles per gallon of 2021 car models. The intercept Value = 6.084, which is the least value of highway fuel economy a 2021 car model could have.The Least Square Regression Line produces a fitted model of the linear relationship between a given set of data.
Using technology such as Excel or a linear regression calculator, the linear model in the form y = a + bx produced by the data in the table attached is Ŷ = 1.264X + 6.084 ;
Where ; Ŷ = Predicted value of highway fuel economy. X = predictor variable, City Fuel economy. 1.264 = slope value; which is the rate of change in highway fuel economy per unit change in City Fuel economy. 6.084 = Intercept, which is the value of, highway Fuel economy when the city fuel economy is Zero.Therefore, the Least Square Regression Line shows that the there is a positive linear association between City and highway Fuel economy.

If a roof is 24 feet high and if you leaned a 26 foot ladder against the side of a building how far away from the building is the base of a ladder to reach the roof
Answers
Answer: 35.4 feet.
Step-by-step explanation:
Given data:
Height of the roof = 24 feet
Height of the ladder = 26 foot
Solution:
c^2 = a^2 + b^2
a = 24
b = 26
c^2 = 24^2 + 26^2
c = √576 + 676
c = √1252
c = 35.4 feet
The foot of the ladder is 35.4 foot away from the top of the ladder.
Answer:
The distance between the base of the ladder and the building is 10 ft
Step-by-step explanation:
Here, we want to calculate the distance between the foot of the ladder and the building
To get this, we need to have a pictorial representation. Please check the attachment for this
From the pictorial representation, we can see a right angled triangle with a hypotenuse of 26 feet and the other side being 24 feet. We now need to get the third side of this triangle which represents the distance we want.
Mathematically, we can calculate the distance using Pythagoras’ theorem which states that the square of the length of the hypotenuse is equal the sum of the squares of the two other sides of the triangle.
Let the distance we are looking for be D
26^2 = 24^2 + D^2
D^2 = 26^2 - 24^2
D^2 = 100
D^2 = 10^2
D = 10 feet

A fisherman can row upstream at 5 mph and downstream at 10 mph. He started rowing upstream until he got tired and then rowed downstream to How far did the fisherman row if the entire trip took 3 hours? starting point
Answers
Answer:
We have been given that the upstream speed is and the down stream speed is .
Let the fisherman traveled a distance of x miles.
The total time of the trip is 6 hours.
Relations between speed (s), time (t) and distance (d) is
Hence,
Time upstream + time downstream = 6
lcm = 10
=>
Cross multiplying,
x = 20 miles .. Answer.
Step-by-step explanation:
The correct answer would be; 20 miles.

PLEASE HELP! THANKS!!!
Answers
Answer:
A. 3
B. 4.5
Explanation:
A. 2(5x - 3) = 24
10x - 6 = 24
then add six on both sides
U get 10x = 30
divide 10 on both sides
U get x is 3
B. 5(2x + 1) = 50
10x + 5 = 50
minus five on both sides
10x = 45
divide by 10 on both sides
The answer is x = 4.5

What value of x satisfies this equation? log(5x+20)=2
Answers
Answer:
16
Step-by-step explanation:
Given expression:
log(5x + 20) = 2
From the given expression, we are to find x;
Using the rule of logarithm, we can solve this problem;
logₐb = C
b = Cᵃ
So;
log(5x + 20) = 2
this is to base 10;
5x + 20 = 10²
5x = 100 - 20
5x = 80
x = 16

The regular price of a swimsuit in the junior department of a store is $54. The store advertises an end-of-season sale at 40% off the regular price of all swimsuits. Two weeks later the store advertises a bonus sale at an additional 1/5 off the end-of-season sale price of all swimsuits. Shannon and Mary decide this is a great time to shop for swimsuits. Shannon figures that the swimsuits are now 60% off the regular price. Mary disagrees, because she figures that the total discount is actually less than 60%.
a. What is the cost of a swimsuit during the end-of-season sale? Justify your reasoning using a model.
b. What is the cost of a swimsuit during the additional 1/5-off bonus sale? How can you show this with a model?
c. Did Shannon or Mary figure the discount correctly? Use a model to explain.

Ram buys an article for $ 1800 and sells it at 10% loss. Find its selling price. *
Answers
Answer:
The answer is $180
Step-by-step explanation:
10% = 0.10
.10 x 1800 = 180
Answer:
cost price ( cp) =$ 1800
loss = 10%
selling price ( sp) = ?
we know,
sp= cp - loss percent of cp
= 1800- 10/100 × 1800
= 1800 - 0.1× 1800
= 1800-180
=$1620
: . $1620 is the selling price of an article.
