What is the sum of the finite arithmetic series 4+8+12+16...+76
Alexxx [7]
A(n)=4+4(n-1)

a(n)=4+4n-4

a(n)=4n

76=4n

n=19

The sum of any arithmetic sequence (series are infinite) is:

(a+a(n))(n/2)

The average of the first and last terms times the number of terms, in this case we found that n=19 so:

19(4+76)/2=760

erastovalidia [21]

Answer:

<u>Find the slope:</u>

  • m = \frac{y2-y1}{x2-x1} = \frac{9 - 1}{-6 - 4} = -\frac{8}{10} = -\frac{4}{5}

<u>Use point-slope form and one of the points:</u>

  • y - y₁ = m(x - x₁)
  • y - 1 = -\frac{4}{5}(x - 4)

Roenfeld Corp believes the following probability distribution exists for its stock. What is the coefficient of variation on the
jok3333 [9.3K]

Complete question is attached;

Answer:

Option D: 0.3069

Step-by-step explanation:

Formula for coefficient of variation on the company's stock is;

CV = σ/E(r)

Where σ is the standard deviation and E(r) is expected value of return.

From the attached image, we can find E(r) as;

E(r) = 0.45(25) + 0.5(15) + 0.05(5)

E(r) = 19%

From online calculation, the standard deviation is 5.83%

Thus;

CV = 5.831/19

CV ≈ 0.3069
