Simplify by which gives you 3/5
Answer:
7. combination; 25C6 = 177100
8. combination; 15C5 = 3003
Step-by-step explanation:
7. The order of the committee member selections is not important. (It would be if specific people filled specific positions on the committee.) Hence, the number is a number of combinations of 25 people taken 6 at a time.
__
8. The order of players is not important, as it might be if specific choices filled specific positions on the team. (The problem statement gives no indication that is the case. It is only by our knowledge of basketball teams that we entertain the possibility that order might be important.) Hence, the number is a number of combinations of 15 people taken 5 at a time.
_____
Of course, nCk = n!/(k!(n-k)!)

Answer:
0.1979 or 19.79%
Step-by-step explanation:
If 20% of all bulbs are defective, there is a 20% chance of each bulb being defective and an 80% chance of each bulb not being defective.
This is a binomial probability model with probability of success (bulb being defective) of p=0.20.
In order for the lot to pass inspection, it must contain either zero or one defective bulb, the probability of one of these scenarios occurring is:
The probability that the lot will pass inspection is 0.1979 or 19.79%.
Answer:
y = 1/3x -4
Step-by-step explanation:
Solve for y
3x-9y = 36
Subtract 3x
3x -3x-9y = -3x +36
-9y = -3x +36
Divide by -9
-9y/-9 = -3x/-9 + 36/-9
y = 1/3x -4
This is in slope intercept form ( y = mx+b) where m is the slope and b is the y intercept
