De dos variables x e y se sabe que la desviación típica de x es √3, la media y la desviación típica de y valen 1 y 2, respectivamente, y la ecuación de la recta de regresión de y sobre x es 2x+3y=6

What is the value of r of the geometric series?

What is the value of x in the diagram below?

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
