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.

Answer:
154 people work in marketing.
55 people work in sales.
Step-by-step explanation:
For every 5 people employed in sales, there are 14 employed in marketing.
This means that:
5/(5+14) = 5/19 of people work in sales.
14/(5+14) = 14/19 of people work in marketing.
Total of 209 people:
14*209/19 = 154
154 people work in marketing.
5*209/19 = 55
55 people work in sales.
Answer:
F(-6)=10
Step-by-step explanation:
From the set of ordered pairs we have,
(-6,10)
This means that when we substitute
x=-6 into the function the result is 10.
Thus,
The last choice is the correct option
Answer:
4
Step-by-step explanation:
2(3) = 6 - 2 = 4
Answer:
x=-22
Step-by-step explanation:
to get x by itself, subtract 12 from both sides: -22=x
