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

One for each person
I wanna say A. y = 3x + 5 y= 1/2x + 2 but I really am not sure
Hope that I kinda helped
He has 11 quarters, 9 dimes, and 55 nickels.
11x.25=2.75
9x.1=.9
55x.05=2.75
2.75+2.75+.9=6.4
Answer:
15.5%
Step-by-step explanation:
Subtract the original amount from the new amount to determine the difference. Then divide the difference by the original amount to get the decimal version of the changed percentage.
$161,700 (increased amount) - $140,000 (original amount) = $21,700 (difference)
$21,700 / $140,000 = 0.155 or 15.5%
