Which of the following decimals has a 2 in the hundredths place? 7.162 -8.745 5.327

\( ( \frac { 6 } { 5 } ) ^ { 7 } \div ( \frac { 6 } { 5 } ) ^ { 5 } = ( - ) ^ { 7 - 5 } = ( - ) \)

33. A factory makes low cost soccer balls with diameters that are normally distributed with mean \( \mu \mathrm{cm} \) and standard deviation 0.25 cm . (a) Estimate the number of balls in a random sample of 200 balls that have diameters within 0.3 cm of the mean diameter. (b) The diameters of \( 80 \% \) of the soccer balls produced by this factory have diameters within \( k \mathrm{~cm} \) of the mean diameter. Find the value of \( k \). (c) \( 25 \% \) of the balls have diameters less than 21.832 cm . Find \( \mu \).

Translate the problem to an equation. Do not solve. A gameboard has 62 squares. If you win 30 squares and your opponent wins the rest, how many does your opponent get?
