José ha adquirido un paquete de hojas blancas, su compañera karina le dió/quitó (mi maestra me dictó "dió", pero yo estoy convencido que quiso haber dicho "quitó", pero como no estoy seguro estaría muy agradecido con el que logré resolver mi gran problema),una tercera parte y rosa se quedó con una cuarta parte. si ana tomó una quinta parte del resto y juanita se llevó 20 hojas,¿cuántas hojas tenía el paquete? ¿qué expresión algebraica representa las hojas que tomo: karina, rosa, ana? cuál es la ecuación o modelo que se construye para resolver esta situación? ¿cuál es la cantidad que satisface como solución?

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
