Answer:
0.0782 (7.82%)
Step-by-step explanation:
The required probability will be found by using the Binomial Distribution which fits the case of n independent events each with a probability of success equal to p with k successes.
The PMF (Probability Mass Function) is
Where 
LabTech states that the probability that a microscope is defective is 0.17%, p=0.0017, q=0.9983. We need to know the probability that k=1 microscope is defective out of a set of n=50 of them. We now apply the formula
Which means that there is a 7.82% of probability to get 1 defective microscope out of the first 50
Answer:
18
Step-by-step explanation:
make a ratio relation:
3 trainers : 12 dogs
x trainers : 72 dogs
3/12 = x/72
solve for x, and you get 18
Answer:
We need approximately 1667 floppy disc to store 
bytes of data.
Step-by-step explanation:
We are given the following information in the question:
A floppy disc can store 1440000 bytes of data.
We have to convert 1440000 in a standard form.
Standard Form:
- Standard form is a way of writing down very large or very small numbers easily.
- It helps us to express large numbers in powers of 10
The standard form can be written as:
We have positive power of 10 because we have to move to the right of the decimal point.
A hard disc can store bytes of data.
Number of floppy disks needed to store the bytes of data =
Thus, we need approximately 1667 floppy disc to store bytes of data.
Answer:
Each side is 8.55
Step-by-step explanation:
The perimeter of a square is given by
P =4s
34.2 = 4s
Divide each side by 4
34.2 /4 = 4s/4
8.55 = s
Each side is 8.55
