Components 1 and 2 are connected in parallel and therefore the subsystem they form works if either component 1 or 2 works. The subsystem containing components 3 and 4 only works if both component 3 and 4 work. The whole system works if at least one subsystem works. If components all work independently of one another; P(component i works) = .9 for i = 1, 2; and P(component i works) = .8 for i = 3, 4, calculate P(system works). Please set up the probability formulas as part of your work!

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
