The space shuttle flight control system called PASS (Primary Avionics Software Set) uses four independent computers working in p

Ierofanga [76]

Answer:

f(x) = P(X≤4) = 4Cx * 0.0005^x * 0.9995^(4-x)

Step-by-step explanation:

Given

The range of values is given as {0,1,2,3,4}

Because any computer can fail.

Given that the failure of the computers are independent and

The probability of failure is given as 0.0005.

Cumulative Distribution Function is the the probability that a random variable is less than or equal to a specific value

So, we'll take the binomial effect into consideration.

It is given as

f(x) = P(X ≤ x) = 4Cx * 0.0005^x * (1 - 0.0005)^(4 - x)

f(x) = P(X≤4) = 4Cx * 0.0005^x * 0.9995^(4-x)

15. What is the area of ADEF shown in the figure? Show your work.

Mariulka [41]

Answer:

A = 189 yd²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Here b = DE = 21 , h = the line from F to DE = 18 , then

A = $\frac{1}{2}$ × 21 × 18 = 10.5 × 18 = 189 yd²

AURORKA [14]

Answer:

If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X.

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A(-2, 1)

Point B(1, -1)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(1+2)^2+(-1-1)^2}$
[Distance] [√Radical] (Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(3)^2+(-2)^2}$
[Distance] [√Radical] Evaluate exponents: $\displaystyle d = \sqrt{9+4}$
[Distance] [√Radical] Add: $\displaystyle d = \sqrt{13}$
[Distance] [√Radical] Evaluate: $\displaystyle d = 3.60555127546$
[Distance] Round: $\displaystyle d \approx 3.6$
