maksim [4K]

Solution :

1). The cost of the formula is given as :

   $ 19,350 + $12 x

2). 95% \text{confidence interval} for the prediction is :

    $21430 - 1.96 \times 220 < \text{Yf} < 21430+1.96 \times 220$

     $20998.8 < \text{Yf} < 21861.2$

     $20999 < \text{Yf} < 21861$    (rounding off)

3). r = 0.92

Therefore, $r^2 = 0.8464$

That is 84.64 % of the variability in the moving cost is best explained by the number of moves.

{2x + 3y = 5}{ y= 5 x -4}
Natasha_Volkova [10]

Solve the system using substitutions:

\begin{gathered} 2x+3y=5 \\ 2x+3(5x-4)=5 \\ 2x+15x-12=5 \\ 17x=5+12 \\ 17x=17 \\ x=\frac{17}{17} \\ x=1 \end{gathered}

x has a value of 1. Use this value to find the value of y.

\begin{gathered} y=5x-4 \\ y=5\cdot1-4 \\ y=5-4 \\ y=1 \end{gathered}

y has a value of 1.

x=1

y=1
