Con los siguientes datos recolectados, calcule las medidas de tendencia central (media, mediana y moda) y de dispersión (rango, desviación media, varianza, desviación típica o estándar y el coeficiente de variación) 1. Las calificaciones de 50 alumnos en Estadística han sido las siguientes: 5, 2, 4, 9, 7, 4, 5, 6, 5, 7, 7, 5, 5, 2, 10, 5, 6, 5, 4, 5, 8, 8, 4, 0, 8, 4, 8, 6, 6, 3, 6, 7, 6, 6, 7, 6, 7, 3, 5, 6, 9, 6, 1, 4, 6, 3, 5, 5, 6, 7.

8121 because

130,000 divided by 16 is 8121

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
