Answer:
Explanation:
There are only two mutually exclusive possibilities for each complex electronic system: being <em>defective</em> or being <em>not defective</em>:
- Number of complex electronic systems: 7
- Nmber of defective systems: 2
- Number of not defective systems: 5
<em>Probability </em>that no defective systems are found in the sample is the equal to the probability of selecting them consecutively without replacement and finding each one is not defective:
- Porbability the first is not defective × probability the second is not defective
- 5/7 × 4/6 = 20/42 = 10/21
Answer:
picture from Goldbach's conjecture.
Step-by-step explanation:
Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states:
Every even integer greater than 2 is the sum of two primes.
The conjecture has been shown to hold for all integers less than 4 × 10^18, but remains unproven despite considerable effort.
So on the red and blue axes you see primes. The list of black numbers are even numbers.
Answer: (9,5) and 2
Step-by-step explanation:
Get the difference between the coordinate points (9,5)
Multiply by 2
Answer:
The answer is
D. V= 19200- 12t
Step-by-step explanation:
in this problem, we already know that the pool contains 19200 gallons of water
and the pool is draining at 12 gallons per minutes, hence the volume is decreasing at that rate
Therefore for t minutes it will decrease by 12t
hence the volume after t minutes will be
V= 19200-12t
