Answer:
<L+<M+<N=180
<NLM and <XLN are supplementary meaning their angle measure add to 180.
therefore,44+46+L=180
90+L=180
l=90
If l=90 then the <NLX is also 90 since they are supplementary angles
therefore, 3x+42=90
3x=48
x=16

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
(7^2)x = 1
x = 1/(7^2) = 7^(-2).
You obtain the value of x by dividing both sides by 7^2 and the inverse of 7^2 is 7^(-2).
