Answer:
62 cups
Step-by-step explanation:
This ratio problem can easily be solved if we write 2 fractions and equate to each other.
The leftside fraction would be the "ratio", that is 8/31.
The right side fraction would be the actual amount, that is:
16 cups for venom
x cups for water
We need to find x. Remember to keep Venom on top (numerator) and water on bottom (denominator). Let's write the ratios (fractions) and equate and cross multiply and solve:
So,
Bane needs 62 cups of water
Answer:
The probability of founding exactly one defective item in the sample is P=0.275.
The mean and variance of defective components in the sample are:
Step-by-step explanation:
In the case we have a lot with 3 defectives components, the proportion of defectives is:
a) The number of defectives components in the 5-components sample will follow a binomial distribution B(5,0.075).
The probability of having one defective in the sample is:
b) The mean and variance of defective components in the sample is:
The Chebyschev's inequality established:
