Answer:

-704

Step-by-step explanation:

Given the sequence

A = -4 - 6i

To find

Sum of terms from i=5 to i=15

<h3>Solution</h3>

We see the sequence is AP

The required sum is

S₅₋₁₅ = S₁₅ - S₄

Using sum of AP formula

Sₙ = 1/2n(i₁ + iₙ)

Finding the required terms

i₁ = - 4- 6 = -10
i₄ = -4 -6*4 = - 28
i₁₅ = -4 -6*15 = -94

Getting the sum

S₄ = 1/2*4*(-10 - 28) = -76
S₁₅ = 1/2*15*(-10 - 94) = -780
S₅₋₁₅ = S₁₅ - S₄ = -780 - (-76) = - 704

A commuter must pass through 5 traffic lights on her way to work and will have to stop at each one that is red. She estimates th

sergij07 [2.7K]

Answer:

(a) The mean or expected value of X is 2.2.

(b) The standard deviation of X is 1.3.

Step-by-step explanation:

Let X = number of times the traffic light is red when a commuter passes through the traffic lights.

The probability distribution of X id provided.

The formula to compute the mean or expected value of X is:

$\mu=E(X)=\sum x.P(X=x)$

The formula to compute the standard deviation of X is:

$\sigma=\sqrt{E(X^{2})-(E(X))^{2}}$

The formula of E (X²) is:

$E(X^{2})=\sum x^{2}.P(X=x)$

(a)

Compute the expected value of X as follows:

$E(X)=\sum x.P(X=x)\\=(0\times0.06)+(1\times0.25)+(2\times0.35)+(3\times0.15)+(4\times0.13)+(5\times0.06)\\=2.22\\\approx2.2$

Thus, the mean or expected value of X is 2.2.

(b)

Compute the value of E (X²) as follows:

$E(X^{2})=\sum x^{2}.P(X=x)\\=(0^{2}\times0.06)+(1^{2}\times0.25)+(2^{2}\times0.35)+(3^{2}\times0.15)+(4^{2}\times0.13)+(5^{2}\times0.06)\\=6.58$

Compute the standard deviation of X as follows:

$\sigma=\sqrt{E(X^{2})-(E(X))^{2}}\\=\sqrt{6.58-(2.22)^{2}}\\=\sqrt{1.6516}\\=1.285\\\approx1.3$

Thus, the standard deviation of X is 1.3.
