Length of a rectangle is 5 cm longer than the width. Four squares are constructed outside the rectangle such that each of the sq

azamat

Answer:

The perimeter of rectangle is $18\ cm$

Step-by-step explanation:

Let

x-----> the length of the rectangle

y----> the width of the rectangle

we know that

$x=y+5$ ----> equation A

$120=xy+2x^{2}+2y^{2}$ ---> equation B (area of the constructed figure)

substitute the equation A in equation B

$120=(y+5)y+2(y+5)^{2}+2y^{2}$

$120=(y+5)y+2(y+5)^{2}+2y^{2}\\ 120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\ 120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\120=5y^{2}+25y+50\\5y^{2}+25y-70=0$

using a graphing calculator -----> solve the quadratic equation

The solution is

$y=2\ cm$

Find the value of x

$x=y+5 ----> x=2+5=7\ cm$

Find the perimeter of rectangle

$P=2(x+y)=2(7+2)=18\ cm$

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)
