<u>Answer:</u>
An equation that relates the speeds of the two legs of the trip
<u>Explanation:</u>
Given, we have to use x to represent the speed on the second leg
Speed on first leg when increasing your speed by 40 mph will be (x-40)
Distance is given as 640 miles and time is calculated as
According to the question, increasing speed saved four hours
Therefore, the equation that relates the speeds of the two legs of the trip will be
Answer:
The mean of T is 10 seconds
Step-by-step explanation:
The given parameters are;
The mean completion time of each step, μ = 10 seconds
The standard deviation, σ = 5 seconds
Each step is independent from the other steps
The variable that represents the total completion time for the three steps = T
We have the mean of T, , given by the combined mean as follows;
Where;
n₁ = n₂ = n₃ = 1, each step is taken only once, we have;
Therefore, the mean of T = 10 seconds
