Answer is 52 hours bc you divide 320 by 40 and you get 8 then divide 416 by 8 and you get 52
23x and 9x are alike terms so
23x-9x
14x
Answer:
i think it's 7
Step-by-step explanation:
perimeter is l+l+w+w
so 17+17=34
48-34=14
14/2=7
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
