I am 100% sure the answer is a.4

Because it was (2,3) then became (8,12)

2*4= 8 and 3*4= 12

The numbers 2 and 3 were multiplied by 4 to get 8 and 12

(1x) +(3x)+(7x-10)= 180

Dimas [21]

Combine the x terms:
11x-10=180
Add Both sides by 10:
11x=190
Divide both sides by 11:
X=190/11

The probabilities that a batch of 4 computers will contain 0, 1, 2, 3, and 4 defective computers are 0.4521, 0.3970, 0.1307, 0.0

Answer:

The standard deviation of given probability distribution is 0.767.

Step-by-step explanation:

We are given the following information in the question:

X: 0 1 2 3 4

P(x): 0.4521 0.3970 0.1307 0.0191 0.0010

Formula:

$\text{Mean} = \sum X.P(x)\\= 0(0.4521) + 1(0.3970) + 2(0.1307) + 3(0.0191) + 4(0.0010)\\= 0.7197$

$\mu = 0.7197$

Formula:

$\text{Variance} = \sum (X-\mu)^2E(x)\\= (0-0.7197)^2(0.4521)+(1-0.7197)^2(0.3970)+(2-0.7197)^2(0.1307)+(3-0.7197)^2(0.0191)+(4-0.7197)^2(0.0010) \\=0.587$

$\text{Standard Deviation} = \sqrt{\text{Variance}}\\= \sqrt{0.587} = 0.767$

The standard deviation of given probability distribution is 0.767.
