Consider a sample x1, x2,…, xn and suppose that the values of x, s2, and s have been calculated. a. Let yi 5 xi 2 x for i 5 1,…, n. How do the values of s2 and s for the yi’s compare to the corresponding values for the xi’s? Explain. b. Let zi 5 (xi 2 x)ys for i 5 1,…, n. What are the values of the sample

to determine the unit cost your would divide the total cost by the number sold.

step-by-step explanation:

cause i just did this and got the answer

you're welcome

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.

english maybe i can ..
