Suppose that x is normally distributed with mean 110 and standard deviation 30. a. what is the probability that x is greater than 170?

Standard the random variable using the transformation



where and are the mean and standard deviation of , respectively.



Now, you can recall that for any normal distribution, approximately 95% of its data falls within 2 standard deviations of the mean, so to either side, there is approximately 2.5% of data that falls below 2 standard deviations from the mean, and 2.5% that falls above . In other words, .

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

You are dumb you will drop out of high school
