Answer:
Step-by-step explanation:
the probability that x iPads are defective in the sample follows a hypergeometric distribution, so it is calculated as:
Where 
Because we have a N elements with k elements that are defective and we are going to take a sample of n elements. So, replacing N by 100, k by 7 and n by 3, we get:
Now, the probability of rejecting the shipment is the probability that at least one iPad of the sample is defective, so:
Then:
Finally, the probability of rejecting the shipment is:
Answer:
6 $10 bills
Step-by-step explanation:
First you have to make a system of equations like such
5x + 10y = 150
x + y = 24
Now you can use any strategy to simplify it but I'll use multiplication and the subtraction:
5x + 10y = 150 - 5x + 5y = 120 = 5y = 30 this simplified is y = 6. You then substitute 6 for y in either equation. x + 6 = 24 and make it on opposite sides. x = 18.
So 18 $5 bills and 6 $10 bills
The only thing you should do is to divide $27.60 by 24 so the answer is $1.15 :)))

Answer:
5/6
Step-by-step explanation:
So to do this, lets convert all of these fractions into decimals by dividing:
5/6 --> 0.833...
7/12 --> 0.583...
4/7 --> 0.571...
2/3 --> 0.66...
From this, it can be see that it is 5/6, since it is a larger decimal compared to the other choices.
Yes, because if you round up or round down it'll be 0.02 or 0.01.
If you put them on the number line, it'll between 0 and 1.
