Объяснение:
t = 22,16 - 10,44 = 11,72
z = 38 - 35,5 = 2,5
(2×11,72)/(2,5) - (11,72)/(2×2,5) = (2×2×11,72)/(2×2,5) - (11,72)/(2×2,5) = (46,88)/(5) - (11,72)/(5) = (35,16)/(5) = 7,032
(2×11,72) / (2,5) - (11,72) / (2×2,5) = (2×2×11,72) / (2×2,5) -
(11,72) / (2×2,5) = (46,88) / (5) - (11,72) / (5) = (35,16) / (5) = 7,032
