Un oceanógrafo registró durante una semana la altura promedio de la marea en dos periodos de 12 horas por día. En un cuaderno de notas escribió: El domingo y el lunes en las primeras 12 horas la marea media fue de 1.2 m y en las segundas 12 horas de 0.95 m; el martes, de 1.1 m y 1.0 m; el miércoles, de 1.2 m y 0.90 m; el jueves, de 0.98 m y 1.1 m; el viernes, de 0.95 m y 1.09 m y el sábado, de 1.3 m y 1.1 m. El oceanógrafo deberá asentar esos datos en un formulario organizado en filas y columnas. Si el oceanógrafo te pidiera que llenes tú el formulario, ¿cómo lo harías?

There is a spinner with 14 equal areas, numbered 1 through 14. if the spinner is spun one time, what is the probability that the result is a multiple of 2 or a multiple of 5?

For problems 29 - 31 the graph of a quadratic function y=ax^2 + bx + c is shown. tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
