Answer:
x = 6.75 cars
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 65
14 people generally sell 5 cars
19 generally sell 6 cars
12 generally sell 7 cars
9 generally sell 8 cars
11 generally sell 9 cars
We have to calculate the sample mean.
Formula:
Thus, the weighted sample mean is 6.75 cars.
The period of the given function is T = 2π
<h3>
What is the period of the function?</h3>
The period T of a function f(x) is such that:
f(x + T) = f(x).
In this case, our function is:
f(θ) = e^{iθ}
Remember that this can be written as:
f(θ) = cos(θ) + i*sin(θ)
So yes, this is in did a periodic function.
Then the period of the function f(θ) is the same as the period of the cosine and sine functions, which we know is T = 2π.

Answer:
Solve each equation for x. 1) x – 15 = 24 => x = 39 2) 18 = −6 + x => x = 24 3) 19 — X = 8 => x = 11 4) x – 22 = 24 => x = 46 5) 24 — X = 17 => x = 7 6) 16 — X = 3 ...
