**6th Grade Statistics**

The student is correct because the median is used to find the middle numeric value of a data set, the mean balances out the data so all numbers in a data set are the same. This means that the mean and median can only be used for a numeric data, so this student is correct.

**6th Grade Statistics**

One student says you can only use the mode to describe categorical data, but you can use the mode, median, and mean to describe numerical data. Is the student correct? Why?

i have some problems doing trig the first one is: Show that cos(x/2) sin(3x/2) = ½(sinx + sin2x) i know that you are supposed to substitute all those trig function things in it but i kind of forgot how to the only that i can see substituting in is the double angle one ...

**chemistry**

Which solution would CaC2O4 be most soluble in? Na2C2O4 NaHC2O4 H2C2O4 NaCl HCl I due to common ions i think it would be one of the first three and i think it is Na2C2O4 because the other 2 have Hydrogen. Is it Na2C2O4? No, the common ions work just the other way; CaC2O4 will ...

The balanced equation doesnt seem to help because the thiosulfate is not in the equation, I think it is preventing the reaction from going backwards. THe equation is: 2iodide ion + hydrogen peroxide + 2 H3O --> elemental iodide + 4 H2O within the reaction there is also ...
