Answer:
This is not really clear, I will assume that the values in the question are:
{0, 1, 0, 2, 3, 2, 3, 4}
For a set of N elements, {x₁, x₂, ..., xₙ}
The mean of the set is given by:

In the case of our set, {0, 1, 0, 2, 3, 2, 3, 4}, we have 8 values.
Then the mean of our set is:

Answer:
18.58 cm
Step-by-step explanation:
8^2 - 6^2 = sqrt 28
sqrt 28 = 5.29
8 + 5.29 + 5.29 = 18.58
9514 1404 393
Answer:
25°
Step-by-step explanation:
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(?) = 25/60
? = arcsin(25/60) ≈ 24.62°
The indicated angle is about 25°.
Answer:
(x + y)(5 + a)
Step-by-step explanation:
5x + 5y + ax + ay
5(x + y) + a(x + y)
(x + y)(5 + a)
