Step-by-step explanation:
A slope of -3/5 means the line drops 3 units for each 5 units it goes to the right. Then you can find another point on the line by going 5 uints to the left (to x=-2) and 3 units up (to y=1).
Plot the given point and the one just computed and draw the line through them.

Step-by-step explanation:
substitute the value of the variable into the equation and simply
Answer:
The 95% confidence interval for the difference between the Route B and Route A commuting times is -3.771808 to 1.771808
Step-by-step explanation:
Here we have the confidence interval is given by the following equation;

= 49 Minutes
σ₁ = 2 Minutes
= 50 Minutes
σ₂ = 4 Minutes
n₁ = n₂ = 10 days
α = 0.05
At 95%, from the z score table , z
=
1.959964 ≈ ± 1.96
Plugging in the values Solving we get
Δμ Min = -3.771808 and Δμ Max = 1.771808.
