In an experiment the colours of 50 cars passing was recorded. 17 silver cars were recorded. What is the relative frequency of a silver car passing?


40 is rounded to the nearest whole. write down the maximum possible length it could have been?

Thanks for your help!

Verified Answer :

Okay, I stink at math. But I do know the last one, which is something. 

You have to divide the 4 by 4 and then get the x alone, but what is done to one side you have to do to the next so, 10/4 = 2.5 

So x ≤ 2.5 

I hopes this helps somewhat.
