Let x be the number of packages being mailed by a randomly selected customer at a certian shipping facility. suppose the distribution is x is as followsx | 1 2 3 4p(x) | .4 .3 .2 .1(a) consider a random sample of size n=2 (two customers), and let xbar be the sample mean number of packagesshipped. obtain the probability distribution of xbar.(b) use (a) to calculate p (xbar < = 2.) if a random sample of size 4 is selected, what is p (xbar < = 1.5)? (hint: don't list all possible outcomes; onlythose for which xbar < = 1.) find v(xbar)

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
