Step-by-step explanation:
x-y^2
Let x = 12 y=3
12 - (3)^2
12 -9

Using the hypergeometric distribution, it is found that there is a 0.0002 = 0.02% probability that exactly 6 patients will die.
<h3>What is the hypergeometric distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
The values of the parameters for this problem are:
N = 25, k = 6, n = 8.
The probability that exactly 6 patients will die is P(X = 6), hence:
0.0002 = 0.02% probability that exactly 6 patients will die.

Answer:
1) 15/32
2) 2
Step-by-step explanation:
1) 3
/8 / 5/4
= 3 · 5
/8 · 4
= 15
/32
2) 4/5 * 2 1/2
First solve --> 2 1/2 = 2 · 2 + 1
/2
= 5
/2
Then solve: 4
/5 * 5
/2
= 4 · 5
/5 · 2
= 20
/10
= 2 · 10
/1 · 10
= 2
Answer:
no Solutions
Step-by-step explanation:
-2x -2y = 6
10x + 10y = -30
multiply the first equation by 5 and add the tower equations together
-10x - 10y = 30
+ 10x +10y = -30
you get all zeros so it had no solutions
