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

Hello!
To put -3x-7y-14=0 into standard form, or ax+by=c where the a value cannot be negative, and there are no fractions or decimals, or any common factors, first add -14 to both sides to get -3x-7y=14. Then, since your a value is negative, multiply the entire equation by -1 which will result in your answer:
3x+7y=-14
Hope this helps!
