How do you subtract 9 2/6 - 6 5/6 =

Answers

Answer 1

Answer: 9 2/6 = ((9*6)+2) / 6 = (54+2) / 6 = 56 / 6
6 5/6 = ((6*6) + 5) / 6 = (36+5) / 6 = 41 / 6

9 2/6 - 6 5/6 = 56 / 6 - 41 / 6 = 15 / 6 = 2 3/6 = 2 1/2

Answer 2

Answer:

Answer:

2 1/2

Step-by-step explanation:

9 2/6= 56/6

6 5/6= 41/6

56-41=15

15/6= 2 3/6

2 3/6 = 2 1/2

Find the quadratic regression for (-1,1) , (0,0) , (1,1)

Answers

3 points define a parabola, so the regression will be unique. You want to find a quadratic polynomial $P_2(x)=\beta_0+\beta_1x+\beta_2x^2$ such that

$\begin{cases}\beta_0-\beta_1+\beta_2=1\n\beta_0=0\n\beta_0+\beta_1+\beta_2=1\end{cases}$

where the system above is generated by setting $P_2(-1)=1$ , $P_2(0)=0$ , and $P_2(1)=1$ .

Since $\beta_0=0$ , we have

$\begin{cases}-\beta_1+\beta_2=1\n\beta_1+\beta_2=1\end{cases}\implies2\beta_2=2\implies\beta_2=1\implies\beta_1=0$

So the regression for the given data points is $P_2(x)=x^2$ .
