Answer: 0.992
Step-by-step explanation:
Given : The three systems detects when a trespass occurs with a probability of 0.98 independently of the others.
Then, the probability that system failed to detect a trespass = 1- 0.98 = 0.02
Since each system works independently ,
Then, the probability that none of 3 systems will detect = 0.2 x 0.2 x 0.2 = 0.008
Then the probability that when a trespass occurs, at least one of the systems will detect it
= 1- P( none of three systems detect)
= 1- 0.008=0.992
Hence, the probability that when a trespass occurs, at least one of the systems will detect it = 0.992
A would be the correct answer because he is up in elevation so that makes the 1200 positive and he goes down 20.4 which is negative and is goes that far down!!
hope this helps
Based on the information given, the true statement true about their gas-price data is A. Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
<h3>
Solution to the gas-price data.</h3>
It should be noted that a standard deviation simply measures how dispersed the data will be in relation to the mean.
From the complete question, the mean of Raquel's data is given as 3.42 while the standard deviation is given as 0.07. On the other hand, the mean of Van's data is given as 3.78 while the standard deviation is given as 0.23.
Therefore, it can be deduced that Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.

The square root of 325 is 18.03
Your answer are options: A, B D F
YOu can just say: 8x8=64
So, evrything biger or = 64, are the answer.
