Solve the system of equations using the substitution method.

ANTONII [103]

The solution of system of equations is: x = 1.6 and y = 1.2

Step-by-step explanation:

Given equations are:

$y = 2-\frac{1}{2}x\ \ \ \ Eqn\ 1\\x-3y = -2\ \ \ eqn\ 2$

Putting $y = 2-\frac{1}{2}x$ in equation 2

$x - 3(2-\frac{1}{2}x) = -2\\x - 6 + \frac{3}{2}x = -2\\x +\frac{3}{2}x = -2+6\\\frac{2x+3x}{2} = 4\\\frac{5x}{2} = 4\\5x = 4 * 2\\5x = 8\\x = \frac{8}{5}\\x = 1.6$

Putting x = 1.6 in equation 2

$1.6-3y = -2\\-3y = -2-1.6\\-3y =- 3.6$

Dividing both sides by -3

$\frac{-3y}{-3} = \frac{-3.6}{-3}\\y = 1.2$

Hence,

The solution of system of equations is: x = 1.6 and y = 1.2

When testing for differences between treatment means, a confidence interval is computed with __________________?

KIM [24]

The confidence interval is based on mean square error. The mean squared error (MSE) of an estimator measures the average of the squares of the errors or deviations. MSE is calculated by the formula attached in the picture, where Xbar is a vector of predictions, X is the vector of predicted values.
