You divide them so it would be 7.6
Answer:
Left side
Ca(OH)2 --> Ca + 2 O + 2 H
2 HBr --> 2 H + 2 Br
Together: Ca + 2 O + 4 H + 2 Br
You have only 1 Br and only 3 H. So you must correct this.
From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844
