Cierto modelo de automóvil tiene un tanque de gasolina con una capacidad de 50 litros. El rendimiento de este auto es de 20 kilómetros por litro de combustible. La compañía de autos sabe que la relación lineal entre la cantidad de combustible y que resta tras haber recorrido cierta distancia X esta dada por la función f(x)=1000-x/20. Suponiendo que un auto de este modelo tiene un tanque lleno, obtén lo que se te pide a) ¿Cuántos kilómetros de gasolina quedaran tras haber recorrido 0, 50, 100, 500 y 1000 kilómetros respectivamente?
b) Con las coordenadas obtenidas del inciso anterior traza la grafica de la función lineal
c) Calcula el valor de m y b en la función
d) ¿Què ángulo de inclinación tiene la recta?

The last time i bought this product , it cost $20.00 but it looks like it cost 29. 60 today? what is the increase

The areas of two similar triangles are 72dm2 and 50dm2. the sum of their perimeters is 226dm. what is the perimeter of each of these triangles?

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
