Range, mode, MAD, median IQR, mean

range=8, mode=1  Median=3 mean=4

Step-by-step explanation:

range= subtract largest from smallest

mode= most frequent

median= middle in an ordered data set

Mean= add them all up and divide by how many you addded up

Range : 8

Mode : 1

MAD : N/A

Median : 3

IQR : N/A

Mean : 4

Step-by-step explanation:

Finding Range:

To find range within a set of numbers, you have to find the smallest number, which in this case is 1. And the biggest number, being 9. Then subtract the biggest number by the smallest.

9 - 1

8 is our range.

Finding Mode:

Finding Mode is finding the most common (or repeated) number within the set.

1 , 1 , 3 , 6 , 9

One appears two times unlike all the other numbers appearing once, therefore having 1 as our mode.

Finding MAD :

I have never heard of this term so I wouldn't want to cheat or give you a wrong answer.

Finding Median :

Median is simply finding the number in the middle of the number set.

1 , 1 , 3 , 6 , 9

3 is in the middle of the set, making 3 our median.

Finding IQR :

Like MAD, I have never heard of this term so I wouldn't want to cheat or give you a wrong answer.

Finding Mean :

Mean is adding all the numbers together, then dividing that final value by the amount of numbers there are.

1 + 1 + 3 + 6 + 9

20

There are five numbers within the set.

20 / 5

4

4 is our mean.

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
