1.Sabiendo que A es directamente proporcional a la raíz cúbica de B. Determina el valor de B cuando A es 4, si cuando A es 6 el valor de B es 27. 2.La eficiencia de una persona es directamente proporcional al sueldo que recibe, e inversamente proporcional a la raíz cuadrada del tiempo que emplea en realizar un trabajo. Si una persona con una eficiencia del 60% tiene un sueldo de 2400 soles y emplea 25 días en hacer su trabajo. ¿Cuántos días empleará otra persona con 75% de eficiencia y un sueldo de 1800 soles?

3.Si "x" es la cuarta diferencial de 20; 16 y 22, determina el valor de "y" sabiendo que es la media proporcional de 8 y "x".

4.El promedio de 5 números es 18. Si agregamos un sexto número el promedio aumenta en 4 unidades. ¿Cuál es el número agregado?

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.

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.
