Total number of people on boat=30
Half as many children as adults means:
Number of children = 1/2 ( Adults)
Let number of adults= A
Then equation is:
So number of children= 1/2 x 20 =10
Answer: 10 Children
This can be also written as y=-2x+2
First of all the - at the beginning = reflection across the x axis.
Then the first 2 is a vertical stretch of 2
the second 2 is a translation of 2 units up.
So
1.ref. across the x axis
2.vert. stretch of 2
3. translation of 2 units up
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
