The probability that a single radar set will detect an enemy plane is 0.9. if we have five radar sets, what is the probability that exactly four sets will detect the plane?
Solution: The given random experiment follows binomial distribution with 
Let x be the number of radar sets that will detect the plane.
We have to find 
Therefore, the probability that exactly four sets will detect the plane is 0.3281
Answer: B
Step-by-step explanation:
Running at the same constant rate, 6 identical machines can produce a total of 270 bottles per minute. Since the machines are identical and running at the same constant rate, it means each of them as the same rate. The rate of each machine can produce would be determined by dividing the combined unit rate by 6. It becomes
270/6 = 45 bottles per minutes
The rate for 10 machines running at the same constant rate would be
10 × 45 = 450 bottles per minutes.
If the 10 machines produce 450 bottles per minutes, then,
In 4 minutes, the 10 machines will produce 4 × 450 = 1800 bottles
Answer:
272.97 m^2
Step-by-step explanation:
first find the area of the square
14*14
196
then find the area of the semicircle
A=πr^2/2
A=3.14*7^2/2
79.97
add the two areas together
196+79.97
272.97 m^2
Answer: A.
Step-by-step explanation: if you look close enough, you can see exactly how long it is, and see that it does also have the two arrows along with it, but it’s the exact same just tilted a little bit but trust me I believe he correct answer is A.
The answer is acute angle
