A quartile divides data into three points a lower quartile (Q₁), median (Q₂), and upper quartile (Q₃) to form four groups of the dataset.

a.  Quartiles  Q₁= 57, Q₂= 59, Q₃= 62

b. Interquartile range, (IQR) = 5

c. 0 and 75 are outlines.

First arrange the given data into increasing order,

We get,  0, 55, 56, 57, 57, 57, 57, 59, 59, 59, 60, 62, 62, 64, 65, 75

Divide into Quartiles,

        ( 0, 55, 56, 57 ) ( 57, 57, 57, 59)  ( 59, 59, 60, 62)  ( 62, 64, 65, 75)

  Q₁ = \frac{57+57}{2}=57

Q₂ = \frac{59+59}{2}=59

Q₃= \frac{62 + 62}{2}=62

Interquartile range (IQR) = Q₃ - Q₁=62 - 57 = 5

High outliner = 1.5 (IQR) + Q₃

                      = 1.5(5) + 62

                      = 69.5

low outliner = Q₁ - 1.5 (IQR)

                   = 57 - 1.5 (5)

                    = 49.5

All the values from arrange data set which are lies outside from 69.5 and 49.5 known as outliners.

Here, 0 and 75 are outliners.

ki77a [65]

Answer:

El chico nació en el año 18 antes de cristo.

La madre nació en el año 40.

Step-by-step explanation:

Las respuestas son fáciles:

- Si en el año 5, el hijo tiene 13 años, hagamos que a partir del año 0 después de cristo sea positivo.

-13-(-5) = -18

- Madre:

-18-22 = -40

Entonces, su edad debería ser negativa, simplemente cambiamos el símbolo y lo pasamos a positivo.

Jan and Wayne went to the store to buy some groceries. Jan bought 2 cans of corn beef hash and 3 cans of creamed chipped beef fo
marin [14]
You can solve this by using the system of equations.
Jan - 4.95 = 2H + 3C
Wayne - 5.45 = 3H + 2C

Use elimination.
-3(2H + 3C = 4.95)
2(3H + 2C = 5.45)

Solve. And you'll get:
-6H + (-9C) = -14.85
6H + 4C = 10.9

Cross out -6H and 6H because they cancel out. And you're left with:
-9C = -14.85
4C = 10.9

Add -9C with 4C, and -14.85 with 10.9.
-5C = -3.95

Divide each side with -5.
C = $0.79

Now to figure out what H is, just substitute the C in one of the equations with 0.79.
5.45 = 3H + 2(0.79)
5.45 = 3H + 1.58
-1.58            -1.58
3.87 = 3H
3.87/3 = 3/3(H)
1.29 = H

Finished!
