Ipromise to give brainliest no ! plz if i get the answers i will have an a in my class ive been asking all this week i beg plzz someone answer what measures of center and spread are best used if the data is symmetrical and asymmetrical? explain your reasoning. what are the different shapes of a data set? explain left and right skew and how this affects the mean of a data set. what is the line of best fit? why do we want the sum of the residuals to be as close to zero as possible? how can you tell if data have outliers? what is the difference between joint and marginal frequency? what do the values of the correlation coefficient tell us? provide an example. what is the difference between correlation and causation? what makes causation difficult to prove?

measures of center (where the data are located along the number line)

measure of spread (how much variation there is about the center)

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u
