The weight of a car can influence the mileage that the car can
obtain. A random sample of 20 cars’ weights and mileage is
collected. The table for the weight and mileage of the cars is
given below. Use Excel to find the best fit linear regression
equation, where weight is the explanatory variable. Round the slope
and intercept to three decimal places.

many different possibilities are there for the range of f? For each
range of f, how many strictly increasing functions are there?

(a) Suppose that τσ=(1 5 2 3)(4) and στ=(1 2 4 5)(3) in S5. If
σ1 = 2, find σ and τ.
(b) In Sn, show that σ = τ if and only if σ(τ)^(−1) = ε. ε is
the identity permutation. Must be written as a proof.
(c) Let σ=(1 2 3) and τ=(1 2) in S3. Show that
S3={ε,σ,σ^2,τ,τσ,τ(σ)^2} and that σ^3=ε=τ^2 and στ=τ(σ)^2, then
fill out the multiplication table for S3.

1, An engineer wanted to determine how the weight of a car
affects gas mileage. The accompanying data represent the weights of
various domestic cars and their gas mileage in the city for a
certain model year. Suppose that we add Car 12 to the original
data. Car 12 weighs 3,305 pounds and gets 19 miles per gallon.
Complete parts(a) through (f) below.
