Which equation represents the line of BEST fit for the data?

Sladkaya [172]

Equation that fits best in data is $y = -30x + 4$ .Although there are no options , kindly match this equation to options available!

<u>Step-by-step explanation:</u>

We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points . On joining points , we see that best fit is a line . General equation of a line is : $y = mx + c$ ,

where m = slope of line & c = intercept.

Let's calculate slope m :

Consider any two given points , let's have ( 4,0) & (3,30) :

Slope = m

⇒ m = $\frac{y_2-y_1}{x_2-x_1}$

⇒ m = $\frac{0-30}{4-3}$

⇒ m = $-30$

So , equation now becomes : $y = mx + c$

⇒ $y = -30x + c$

at x = 0 we have y = 4

$y = -30x + c$

$4 = -30(0) + c$

$c = 4$

Therefore, equation that fits best in data is $y = -30x + 4$ .Although there are no options , kindly match this equation to options available!

The line integral of xydx×x^2y^3dy where c is the triangle with points (0,0) (1,0) (1,2) using green's theorem

lyudmila [28]

If $\mathcal C$ is the boundary of the triangle $D$ , then by Green's theorem

$\displaystyle\int_{\mathcal C}xy\,\mathrm dx+x^2y^3\,\mathrm dy=\iint_D\left(\frac{\partial(x^2y^3)}{\partial x}-\frac{\partial(xy)}{\partial y}\right)\,\mathrm dA$
$=\displaystyle\int_{x=0}^{x=1}\int_{y=0}^{y=2x}(2xy^3-x)\,\mathrm dy\,\mathrm dx$
$=\displaystyle\int_{x=0}^{x=1}x\int_{y=0}^{y=2x}(2y^3-1)\,\mathrm dy\,\mathrm dx$
$=\displaystyle\int_{x=0}^{x=1}x(8x^4-2x)\,\mathrm dx=\frac23$

For every $3.00 donated to a certain charity by Club A, $1.25 was donated by Club B. If the combined total amount donated to the

shtirl [24]

Answer:

D, $18,000.00

Step-by-step explanation:

Club A

$3 x is donated where x is the number of donations

Club B

$1.25x is donated where x is the number of donations

The total of donations is 25500.00

Add the donations times the dollar amount for Club A and Club B and you get the total amount donated

$3x +$1.25x = 25500.00

Combine like terms

4.25x = 25500.00

Divide by 4.25 on each side

4.25/4.25x = 25500.00/4.25

x =6000

There were 6000 donations

We want to find Club A donation amount

$3 x is the amount donated

3*6000 = 18000
