Answer:
Half-life of the goo is 49.5 minutes
191.7 grams of goo will remain after 32 minutes
Step-by-step explanation:
Let denotes initial and final mass.
According to exponential decay,
Here, t denotes time and k denotes decay constant.
So, half-life of the goo in minutes is calculated as follows:
Half-life of the goo is 49.5 minutes
So,
Put
Put t = 32 minutes
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:
