Zwei Frauenteams spielten Basketball. Das Siegerteam erzielte 21 Punkte mehr als das andere Te, Hätten beide Teams nur \( \frac{2}{3} \) ihrer Punkte erreicht. so hätten die Verlierennnen gerade \( \frac{3}{4} \) so viele Pun. geworfen wie das Siegeteam. Wie viele Punkte hatten die beiden Teams am Ende des Spiels erreicht?

Suppose a future student receives an copper sulfate solution unknown that is so darkly blue that no light can be transmitted through the sample and she can't determine the concentration. What should she do? Discard the copper sulfate solution in the chemical waste container.

16.42 Ajuste de los motores de un avión. Los motores que im- pulsan las hélices de un avión se afinan, en algunos casos, usando pulsos. El zumbido del motor produce una onda sonora que tiene la misma fre- cuencia de la hélice. a) Si una hélice de una sola hoja gira a 575 rpm y usted oye un pulso de 2.0 Hz cuando hace funcionar la segunda hé lice, ¿cuáles son las dos posibles frecuencias (en rpm) de la segunda hélice? b) Suponga que se incrementa ligeramente la rapidez de la se- gunda hélice y se determina que la frecuencia del pulso cambia a 2.1 Hz. En el inciso a) ¿cuál de las dos respuestas es la correcta para la fre- cuencia de la segunda hélice de una hoja? ¿Cómo lo sabe

Iirections: If the thesis of this article is to explain the reason for the Berlin Conference HIGHLIGHT 1 SUPPORTING DETAIL It did something much worse, though, with consequences that would reverberate across the years and be felt until today. It established the rules for the conquest and partition of Africa, in the process legitimizing the ideas of Africa as a playground for outsiders. Africa's mineral wealth as a resource for the outside world not be for Africans, and its fate as a matter not to be left to Africans.

3. From your class, how many airplanes traveled over 9 feet on their first throw? 4. What is the sample proportion of airplanes that traveled over 9 feet on their first throw? 5. What do we use the value of the sample proportion to estimate? 6. The Pompute the estimated standard error for the sample proportion in this setting. 7. Compute the margin of error for a \( 95 \% \) confidence interval for the true proportion of paper airplanes that travel over 9 feet on their first flight. 8. Compute a \( 95 \% \) confidence interval for the true proportion of paper airplanes that travel over 9 feet on their first flight.
