podem me ajudar por favor?​

Answer 1

Resposta:

Explicação passo a passo:

a) 10; 11; 5; 13; 7; 13

MA = 10 + 11 + 5 + 13 + 7 + 13 / 6

MA = 59 / 6

MA = 9,83

V = (10 - 9,83)²+ (11 - 9,83)²+(5 - 9,83)²+(13 - 9,83)²+(7 - 9,83)²+(13 - 9,83)²/

6 -1

V = (0,16)² + (1,17)² + (-4,83)² + (3,07)² + (-2,83)² + (3,07)² / 5

V = 0,0256 + 1,36 + 23,32 + 9,42 + 8,00 + 9,42 / 5

V = 51,54 / 5

V = 10,30

Dp = ±√10,30

Dp = ±3,20

b) 22; 20; 14; 23; 21;

MA = 22 + 20 + 14 + 23 + 21 / 5

MA = 100 / 5

MA = 20

V = (22 - 20)²+ (20 - 20)²+(14 - 20²+(23 - 20)²+(21 - 20)²/ 5 - 1

V = (2)² + (0)² + (-6)² + (3)² + (1)² / 4

V = 4 + 0 + 36 + 9 + 1  / 4

V = 50 / 4

V = 12,5

Dp = ±√12,5

Dp = ±3,53

c) 7; 7; 7; 7; 7; 7; 7; 7

MA = 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 / 8

MA = 56 / 8

MA = 7

V = (7 - 7)²+ (7 - 7)²+(7 - 7)²+(7 - 7)²+(7 - 7)²+(7 - 7)²+(7 - 7)²+(7 - 7)² /  8 - 1

V = (0)² + (0)² + (0)² + (0)² + (0)²+(0)²+(0)²+(0)² / 7

V = 0

Dp = ±√0

Dp = ± 0

d) 120; 128; 135; 121; 120;

MA = 120 + 128 + 135 + 121 + 120 / 5

MA = 624 / 5

MA = 31,2

V = (120 - 31,2)²+ (128 - 31,2)²+(135 - 31,2)²+(121 - 31,2)²+(120 - 31,2)²/ 5 - 1

V = (88,8)² + (96,8)² + (103,8)² + (89,8)² + (88,8)² / 4

V = 7885,44 + 9370,24 + 10774,44 + 8064,04 + 7885,44  / 4

V = 43979,6 / 4

V = 10994,9

Dp = ±√10994,9

Dp = ±104,85
