Keeping in mind that the area of a circle is πr².
the actual area will just be the area of the rectangular backyard plus the pool, namely (10*20) + (π15²), which gives us an actual area of
200 + 225π.
now, we know the model and actual are on a 1:20 ratio.
It's choice two. When you are putting the equation into y=mx+b form you have to subtract the 3x and put it onto the same side as 10. Then you would have 2y=-3x+10 then divide everything by 2 to have y be alone. Then it would be y=-3/2x+5 giving you the slope of the line being -3/2
What was i correct was the 2nd step since when multiplying -2x-6 it would be a positive 12 not a negative :)
The expected outcome of spins based on the probability information is 60.
<h3>How to calculate the probability?</h3>
From the information, Joey decides to spin the wheel 60 times. Therefore, the expected outcome of spins is 60.
The thing that the booth owner can do to make the wheel more profitable for himself is to make winning probability less than that of losing.
