20 does not =25$
answer= andrea will not have enough money because she has 20$ which is 5 dollars less than the price
Answer: 4
Step-by-step explanation:
u find it using the formula r= root 3 V/pi*Height
in this case it is root 3*167.55/pi*10 which is equal to 3.99998 and that rounds to 4
Using the binomial distribution, it is found that the mean of X is of 12, with a standard deviation of 3.36.
For each chip, there are only two possible outcomes, either it is defective, or it is not. The probability of a chip being defective is independent of any other chip, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
Probability of exactly <u>x successes on n repeated trials, with p probability.</u>
The mean of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem:
- Six percent of computer chips produced by Cheapo Chips are defective, hence .
- Each month a random sample of 200 chips manufactured that month are taken, hence
Then:
The mean of X is of 12, with a standard deviation of 3.36.
