It is thought that basketball teams that make too many fouls in a game tend to lose the game even if they otherwise play well. Let x be the number of fouls more than (i.e., over and above) the opposing team. Let y be the percentage of times the team with the larger number of fouls wins the game.
| x | 1 | 2 | 5 | 6 |
| y | 48 | 44 | 33 | 26 |
Complete parts (a) through (e), given Σx = 14, Σy = 151, Σx2 = 66, Σy2 = 6005, Σxy = 457, and r ≈ −0.993.
(a) Verify the given sums Σx, Σy, Σx2, Σy2, Σxy, and the value of the sample correlation coefficient r. (Round your value for r to three decimal places.)
Σx =
Σy =
Σx2 =
Σy2 =
Σxy =
r =
(b) Find x, and y. Then find the equation of the least-squares line y = a + bx. (Round your answers for x and y to two decimal places. Round your answers for a and b to three decimal places.)
x=
y=
y = + x
(c) Find the value of the coefficient of determination r2. What percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? What percentage is unexplained? (Round your answer for r2 to three decimal places. Round your answers for the percentages to one decimal place.)
r2 =
explained = %
unexplained = %
(d) If a team had x = 4 fouls over and above the opposing team, what does the least-squares equation forecast for y? (Round your answer to two decimal places.)
= %

Glucose, C6H12O6, is used as an energy source by the human body. The overall reaction in the body is described by the equation
C6H12O6(aq) + 6O2(g) — 6CO2(g) + 6H2O(1)
Calculate the number of grams of oxygen required to convert 63.0 g of glucose to CO2, and H2O.
mass of O2 = _______ g
Calculate the number of grams of CO2, produced.
mass of CO2 = _______ g
