Answer:
The outlier is 3, and the outlier has a greater effect on the mean because it is an average of all numbers where as the median is just the middle value in the data set. Everything else you can do on your own. To find the mean you add all the numbers up and divide by the total amount of numbers there are, the median you just cross one out from the left and then cross one out from the right and continue doing this until you are left with one number, or if you are left with two numbers you can add those two numbers up and then divide them by 2

Answer:
Step-by-step explanation:
Given that,
v(t) = A + B•sin(ωt)
Then,
When t = 0 v(t)= 7
7 = A + B•Sin(ω×0)
7 = A + B•Sin0
7 = A
Then,
A = 7
v = 7 + B•sin(ωt)
So,
When t = 3, v(t) = 9
v = A + B•sin(ωt)
9 = 7 + B•Sin(3w)
9-7 = B•sin(3ω)
B•sin(3w) = 2. Equation 1
Also, at t = 6 v(t) = 7, at this point, when it returns back to7, it has complete one oscillation
v = A + B•sin(ωt)
7 = 7 + B•Sin(6w)
7-7 = B•sin(6ω)
B•sin(6w) = 0
Sin(6w) = 0 / B
Sin(6w) = 0
Take arcsin of both sides
6w = Sin~1(0)
6w = π, since it has complete one oscillation
Then, w = π /6
w = π/6
Then,
v(t) = 7 + B•Sin(πt/6)
From equation 1
B•sin(3w) = 2.
B•Sin(3 × π/6) = 2
B•Sin(½π) = 2
B = 2
Then,
v(t) = A + B•sin(ωt)
A = 7, B = 2 and w = π/6
v(t) = 7 + 2•sin(πt/6)
