When grading papers you can convert decimals into percents
Lol i forgot how to do this. Sorrryyy.
Mean = total score : frequency
mean x frequency = total score
so
83 = total score : 6
83 × 6 = total score
498 = total score
so the sum of the 6 test scores is 498
2x +8=2x+8
2x-2x=8-8
0x=0
So the answer is 0
You should multiply the numbers to get your solution. either 345*25 or 3 and 25
dose this help?
