Suppose that we are studying the amount of time customers wait in line at the checkout at the Gap and Old Navy. The average wait time at both stores is five minutes. At the Gap, the standard deviation for the wait time is 2 minutes; at Old Navy the standard deviation for the wait time is 5 minutes.

\( \lim _ { x \rightarrow - 5 } \frac { y ^ { 2 } - 25 } { y + 5 } = \)

Emma and Michelle had a total of \( \$ 600 \). Emma gave \( \frac{1}{6} \) of her money to Michelle. Michelle then yave \( \frac{1}{6} \) of her money to Emma. In the end, both much money did Michelle have at first?

In un triangolo rettangolo, con il perimetro d 120 m , l'ipotenusa misura 52 m e un cateto è \( \frac{5}{12} \) dell'altro. Calcola la misura dei cateti. \( [20 \mathrm{~m} ; 48 \mathrm{~m} \)

2.3 Complete the following statements. 2.3.1 If GU \| LE and \( \mathrm{QR} \| \mathrm{LE} \), then GU and QR are \( 2.3 .2 \quad \) If \( \mathrm{ST} \perp \mathrm{UV} \) and \( \mathrm{JK} \perp \mathrm{UV} \), then ST and JK are
