Answer:

Step-by-step explanation:

a )

probability of a computer being ancient = .99

probability of a computer being cutting-edge =.01

probability of two selected  computer being old

= .99 x .99

= .98 or 98%

b )

probability of 5 selected computers being old

= .99 x .99 x .99 x .99 x .99

= .95 or 95%

c )

probability that at least one of the five selected computers is cutting-edge

= 1 - probability of 5 selected computers being old

= 1 - .95

= .05

Given the following functions f(x) and g(x), solve (f ⋅ g)(3) and select the correct answer below:
Ksenya-84 [330]
I believe you may have the order incorrect. If we were looking at g(f(x)) the answer would be 47. We would get this by sticking the 3 in for x in f(x) and solving, which would give us 48. We would then stick that answer in for x in the g(x), giving us 47. 

In its current order the answer would be 28.

Solve the system of equations algebraically. 5x-3y=6 6x-5y=10
erma4kov [3.2K]

Answer:

The solution is x = 0, y =  -2.

Step-by-step explanation:

5x - 3y = 6  

6x - 5y = 10

If we multiply the first equation by 5 and the second by - 3 we get:

25x - 15y = 30

-18x + 15y = -30     Adding these 2 equations eliminates y, we get:

7x + 0 = 0

x = 0.

Substituting x = 0 in the first equation:

5(0) - 3y = 6

y = 6/-3 = -2.
