Determine the value of parameter a, for which the system of equations 3x + 2ay = 1 and (3a - 1)x - ay = 1 has a soulution in the domain of integer
numbers.

I didn't know I am so sorry

Step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
