Ответ:
Responda:
Média = 24 ° C
Extensão = 6 ° C
Explicação passo a passo:
Dado que :
Valores locais de temperatura obtidos:
24, 22, 21, 27, 23, 27
O valor médio da temperatura:
Soma dos valores de temperatura / número de medições
(24 + 22 + 21 + 27 + 23 + 27) / 6
= 144/6
= 24 ° C
Extensão das medidas:
Faixa = (valor de temperatura mais alto - valor de temperatura mais baixo)
Faixa = 27 - 21 = 6 ° C
Ответ:
3x + 4y = 7 -> y = -3/4x + 7/4
