Answer:
No, because this is an observational study.
Step-by-step explanation:
The researchers found that the rate of leukemia for children near high-tension wires was higher than the rate for those not near high-tension wires.
So, the answer is No, the researchers cannot conclude that proximity with high-tension wires causes leukemia in children as this is only an observational study.
Observational study is that study where the researcher observes the effect of a risk factor, diagnostic test or treatment without trying to control who is or is not exposed to it.
Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160
