In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushel
s per acre). Which is the best predicted value for y given x = 7.1? Assume that the variables x and y have a significant correlation. Rainfall (in inches)(x): 10.5,8.8,13.4,12.5,18.8,10.3,7.0,15.6,16.0
Yield (bushels per acre) (y): 50.5,46.2,58.8,59.0,82.4,49.2,31.9,76.0,78.8
Let x= number of board games <span>20x=10410+2.65x </span> <span>-2.65 -2.65 </span> <span>17.35x=10410 </span> <span>/17.35 /17.35 </span> <span>x=600 </span> <span>You would need to sell at least 600 board games to break even</span>
There are three sheets of 10 stickers. This is equal to 30 stickers. There are also 30 single stickers. Split the single stickers and give Gary and Jill 13 each. Then Gary and Jill can each take a sheet of 10. They will both have 23 stickers.
Here you're being asked to recall your own experience in paying for "value meals." How much have you paid per meal?
If each meal costs $6.50, then 5 would cost $13.00 before tax, and
(1.07)(5)($13.00), or $69.55 total.
Note that there's not just one possible total cost, and that we don't know much about this situation but must insert reasonable values, such as a $6.50 per meal unit cost and a 7% tax rate.
