Answer:
the answer is the second to the left :D
Step-by-step explanation:
each number is divided then you solve\
Answer:
a) Hyper-geometric distribution
b1) P(X=2) = 0.424
b2) P(X>2) = 0.152
C1) Mean of X = 1.67
C2) Standard Deviation of X = 0.65
Step-by-step explanation:
b1) P(X = 2) = (5C2 * 7C2)/(12C4) = (10 * 21)/(495) = 210/495
P(X=2) = 0.424
b2) P(X>2) = 1 - P(X≤2) = 1 - [P(X=0) + P(X=1) + P(X=2)]
P(X=0) = (7C4)/(12C4) = 35/495 = 0.071
P(X=1) = (5C1 * 7C3)/(12C4) = (5 * 35)/(495) = 175/495 = 0.354
P(X=2) = 0.424
P(X>2) = 1 - P(X≤2) = 1 - [0.424 + 0.071 + 0.354]
P(X>2) = 0.152
C1) Mean of X = nk/N
k = number of 3-megapixel cameras = 5
n = number of selected cameras = 4
N = Total number of cameras = 12
Mean of X = 5*4/12
Mean of X = 1.67
C2) Standard Deviation of X
Standard deviation of X=(nk/N*(1-k/N)*(N-n)/(N-1))1/2
Standard Deviation of X=(4*(5/20)*(1-5/12)*((12-4)/(12-1))^1/2 =0.65
Standard Deviation of X = 0.65

254.47
Step-by-step explanation:
1/4
d^2
Input is the same as the x-term and output is the same as the y-term.
For example, take a look at the image provided with thee table.
Looking at the first box of our table, notice that if we subtract 5 from 1, we get -4 and if we subtract 5 from 2 we get -3 and if we subtract 5 from 3, we get -2. Notice that in each case, we're subtracting 5 from the input to get the output.
I attached a table so you can practice if you'd like to. All you have to do is subtract 5 from each input and you will end up with the output. The first few are done for you. I also provided an answer key in the next image so you can check your work.
The last one might be a little trick. In the input, we have n which is a variable that represents any number. If we want to find the nth term, we simply subtract 5. So we have n - 5.
First image is practice if you'd like and the second is the key.
If you don't want to do it, no worries.
