Media aritmética: 12, 14, 13, 17, 10, 11, 12, 15

12 + 14 + 13 + 17 + 10 + 11 + 12 + 15 / 8

104 / 8 = 13

media aritmética:

8, 12, 15, 13, 15, 21, 24, 36

8 + 12+ 15 + 13+ 15 + 21 +24 + 36 / 8

144/8 = 18

media aritmética:

12, 21, 22, 42, 13, 24, 20

12 + 21 + 22 + 42 + 13 +24+ 20 / 7

154 / 7 = 22

1. hallar A + B

• "A" es la media de 3, 4, 5 ,6 ,8

3 + 4 + 5 + 6 + 8 / 5

26 / 5 = 5,2

• B es la moda de 2, 2, 3, 3, 4, 2 Mo = 2
• A + B = 5,2 + 2 = 7,2

2. Calcular media y moda de A y B

A es la media de 20, 22, 15, 12 ,11

20+ 22 + 15 + 12 + 11 / 5

80 / 5 = 16

B es la moda de 10, 12, 14, 12, 11

10 + 12 + 14 + 12 + 11 / 5

59 / 5 = 11,8

3. calcular la media 8,12,15, 15, 13, 21, 22, 36

8 + 12 + 15 + 15 + 13 + 21 + 22 + 36 / 8

142 / 8 = 17,75
