Answer:

P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2

Step-by-step explanation:

Given that:

Total Number of cameras (n) = 8

Defective cameras = 4

X: number of defective cameras

For a binomial distribution :

P(x) = nCx * p^x * (1 - p)^(n - x)

Probability of success (p) on each trial is the same = (total number of samples / number of defective samples) = 8/4 = 0.5

If 2 samples are chosen at random :

Then, the binomial probability distribution will be :

P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2

RUDIKE [14]

Answer:

Option B) g(x) is an increasing function, and f(x) is a decreasing function.

Step-by-step explanation:

1) we have

f(x)=-2x+5

This is a linear function

The unit rate or slope is negative

That means ----> Is a decreasing function

2) we have

g(x)

Looking at the table we notice that

The function g(x) is a increasing function, because the y-value increases as the x-value increases

therefore

g(x) is an increasing function, and f(x) is a decreasing function
