2. What 2 by 2 matrix E subtracts the first component from the second component?
What 3 by 3 matrix does the same?

An assembly consists of two mechanical components. suppose that the probabilities that the first and second components meet specifications are 0.87 and 0.84. assume that the components are independent. determine the probability mass function of the number of components in the assembly that meet specifications. x

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
