What is the equation of the line best fit for the following data? Round the slope and y-intercept of the line to three decimal p

kari74 [83]

Answer:

$y=1.383x-1.526$

Step-by-step explanation:

The given data table is

x : 4 7 10 12 13

y : 5 7 12 14 18

We need to find the equation of the best fit line.

The general form of a best fit line is

$y=mx+b$ .... (1)

where, m is slope and b is y-intercept.

$m=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}$

$b=\overline{y}-b\overline{x}$

Using the graphing calculator we get

$m=1.38321\approx 1.383$

$b=-1.52555\approx -1.526$

Substitute m=1.383 and b=-1.526 in equation (1).

$y=1.383x-1.526$

Therefore, the equation of best fit line is $y=1.383x-1.526$ .

Consider the differential equation: dy/dx = (y-2)(x^2+1)

Klio2033 [76]

Answer:

Step-by-step explanation:

Given,

$\dfrac{dy}{dx}=(y-2)(x^2+1)$ ...(i)

Differentiating w.r. to x.

$\dfrac{d^2y}{dx^2}= (y-2)(2x)+ (x^2+1)\dfrac{dy}{dx}$

From equation (1)

$\dfrac{d^2y}{dx^2}= (y-2)(2x)+ (x^2+1)^2(y-2)$

Now, at the point (1,3)

$\dfrac{d^2y}{dx^2}= (3-2)(2\times 1)+ (1^2+1)^2(3-2)$

$\dfrac{d^2y}{dx^2}=6$
