So basically your gonna regaurd 63.5 as 60 +3.5, 60 is 5*12 and the remaining 3.5 is less than the divisor 5, so it would be the remainder
anwser is 63.5/5 treat as 60/5+3.5/5
so anwser is 60/5+3.5/5=0.7=12.7
Answer is y= 1/2x+1
One method is first substituting x=4,y=3 and next once again substituting x=y=2
The arrow because if you cut it in have it is simmetrical
You can write this as 38+2x=124 and solve for x. You then get that x=43
The sampling that Joan is using is known as cluster sampling.
