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

Arandom sample of 150 high school students were asked whether they have a job. the results are shown in the table. have a job do not have a job male 48 35 female 41 26 select a ord or phrase from the drop-down menus to correctly complete the statements describing the association.

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Is the point (0, 8) on the x-axis or y-axis? how do you know?
