Answer:
0.9999
Step-by-step explanation:
Let X be the random variable that measures the time that a switch will survive.
If X has an exponential distribution with an average life β=44, then the probability that a switch will survive less than n years is given by
So, the probability that a switch fails in the first year is
Now we have 100 of these switches installed in different systems, and let Y be the random variable that measures the the probability that exactly k switches will fail in the first year.
Y can be modeled with a binomial distribution where the probability of “success” (failure of a switch) equals 0.0225 and
where
equals combinations of 100 taken k at a time.
The probability that at most 15 fail during the first year is
Answer:
The volume of cube-shaped block is 0.125 cubic feet.
Step-by-step explanation:
We are given the following in the question:
Edge length of storage container =
Edge length of block =
Putting value we get,
Edge length of block =
Volume of cube-shaped block = Volume of cube
Thus, the volume of cube-shaped block is 0.125 cubic feet.
Answer:
each team got 2.875 pizzas
Explanation:
We are given that:
number of teams = 8 teams
number of pizzas = 23 pizzas
Now, these 23 pizzas will be divided equally among the 8 teams.
So, to get the amount that each team will get, all you have to do is divide 23 by 8 and get the result as follows:
amount that each team gets = 23/8 = 2.875 pizzas
Hope this helps :)
Carla is correct because they will not all be exactly the same unless they choose to make them all be the same. Hope I could help! :D
Answer:
<h2>82 in²</h2>
Step-by-step explanation:
The median of the four numbers a, b, c and d. Where a ≤ b ≤ c ≤ d:
We have
84in², 72in², 80in², 84in² → 72in², 80in², 84in², 84in²
The median:
