a population has a mean of 163 and a stndard deviation of 25. find the mean and stardard deviation of the sampling distrubution of sample means with sample size n=52

Which of these numbers of simulations of an event would be most likely to produce results that are closest to those predicted by probability theory? 15, 20, 5, 10

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.

X+ 4y − z = −14 5x + 6y + 3z = 4 −2x + 7y + 2z = −17
