Best ResponseYou've already chosen the best response.0Then use the values of x1, x2, x3, x4, and m to evaluate \[\frac{ \sum_{i=1}^{4}(x1=m)^2 }{4 }\]

Best ResponseYou've already chosen the best response.0Isn't the first equation just telling you to add up x1, x2, x3 and x4...or am I missing something?

Best ResponseYou've already chosen the best response.0the "thingy" is subscript i (small hard to read ;) )

Best ResponseYou've already chosen the best response.0just add them. I think the equation should read:\[\sum_{i=1}^{4}x_i\]

Best ResponseYou've already chosen the best response.0The second equation asks you to take the sum of the squares of x1, x2, x3 and x4

Best ResponseYou've already chosen the best response.0sorry, i couldn't connect. It is a 1, not an i.

Best ResponseYou've already chosen the best response.0Well, that is kind of a strange question. Because, if x1=6, then\[\sum_{i=1}^{4}6=4(6)=24\]

Best ResponseYou've already chosen the best response.0Similarly,\[\frac{\sum_{i=1}^{4}(6)^2}{4}=\frac{4(36)}{4}=36\]
