I would say c hope that helped
Total fish = 100
Carp = 30
Number of fish caught = 20
The random variable X follows hyper-geometric distribution.
Mean = 30 *20 / 100 = 600/100 = 6
Variance = 30*20/100 * ((20-1)*(30-1)/100-1 + 1-30*20/100)
Variance = 600/100 * 56/99
Variance = 112/33
Assumptions: Is that X follows hyper-geometric distribution with the given information.
Answer:
19.55 $
Step-by-step explanation:
3.45$×10=34.5=150% of his money overall
34.5÷3=11.5
11.5×2=23= 100% of his money
23-15%=19.55$

Answer:
The first histogram is the answer.
Step-by-step explanation:
Like any other questions, you can use the process of elimination to answer this question.
There are only one fruit that has a water content of 60 - 64 %
Right away you can eliminate the second answer choice.
There are two fruits that has a water content of 65 - 69 %
All the other three has the same thing
There are only two fruits that has a water content of 70 to 74 %
Right away answer choice three can be eliminated
There are 4 fruits that are 75 - 79 % full with water
Both has same thing
There are 9 friuts that are 80 - 84 % full with water
THERE ARE 2 FRUITS THAT CONTAIN 85 - 89 % water
THE ANSWER IS THE FIRST HISTOGRAM.
