1) Let's convert it to kilometers, using for that a Rule of three
1 mile ---------- 1.600 km
3 -----------------x
2) Multiplying it crossed
3*1.600=1x
4800=x
x = 48
Hi! Could you possibly get a clearer picture? If not I can try my hardest to figure it out
Positive correlation means that if x goes up then y goes up, negative correlation means that if x goes up then y goes down. Since both x and y are increasing each time, it is positive.
6 math books would be 126
5 English books would be 150
126+150=276
