A product is composed of four parts. In order for the product to function properly in a given situation, each of the parts must
svet-max [94.6K]

Answer:

P(working product) = .99*.99*.96*.96 = .0.903

Step-by-step explanation:

For the product to work, all four probabilities must come to pass, so that

P(Part-1)*P(Part-2)*P(Part-3)*P(Part-4)

where

P(Part-1) = 0.96

P(Part-2) = 0.96

P(Part-3) = 0.99

P(Part-4) = 0.99

As all parts are independent, so the formula is P(A∩B) = P(A)*P(B)

P (Working Product) =  P(Part-1)*P(Part-2)*P(Part-3)*P(Part-4)

P (Working Product) = 0.96*0.96*0.96*0.99*0.99

P(Working Product) = 0.903

A truck rental company charges $50 plus $10 per hour. Identify a function that represents the total charge for renting a truck f
Reil [10]

Answer:

  c(h) = 50 +10h

  c(4) = 90 . . . . . it costs $90 to rent the truck for 4 hours

Step-by-step explanation:

The problem statement tells you the total charge is the sum of $50 and a charge of $10 per hour. That is, for h hours, the total charge is ...

  c = 50 + 10h

In functional form, this is ...

  c(h) = 50 +10h . . . . . . total charger for a rental of h hours

__

The function value with an input of 4 is ...

  c(4) = 50 +10·4

  c(4) = 90

Since the input is the number of hours of rental, and the function value is the total charge, this represents the total charge for a rental of 4 hours.
