To find the median, add up the frequency column to find how many trains there were in total. There were 44 trains in total in this grouped frequency table, so work out 44 + 1 2 = 45 2 = 22.5. The median is therefore between the 22nd and 23rd values.
3 is not the GCF, 30 is the GCF. The answer is 30(2+3).
FALSE
A linear equation has the general form Ax + By =C, where the two variables are x and y, while A, B and C are constantes. Then, both varaibles are raised to the power 1; none variable is squared.
