What is the equation of exponential regression equation? Round all numbers you your answer to three decimal places

ExtremeBDS [4]

Given:

The given values are:

$a=0.2094539899$

$b=2.507467975$

$r^2=0.9435996398$

$r=0.9713905701$

To find:

The exponential regression equation for the given values (Rounded to three decimal places).

Solution:

The general form of exponential regression equation is:

$y=a\cdot b^x$ ...(i)

Where, a is the initial value and b is the growth/decay factor.

We have,

$a=0.2094539899$

$b=2.507467975$

Round these numbers to three decimal places.

$a\approx 0.209$

$b\approx 2.507$

Substitute $a=0.209, b=2.507$ in (i) to find the exponential regression equation.

$\hat{y}=0.209\cdot 2.507^x$

Therefore, the correct option is C.

Please solve with explanation

Answer:

The x coordinate of S is b.

Step-by-step explanation:

The coordinates of Point Q are:

(2a+2b)/2, 2c/2

= [(a + b), c].

The slope of the line AB

= (0-2c)/(2b-2a)

= -c/(b-a)

So The slope of the line QS = (b - a) / c = (b - a)/c.

Its equation is

y - c = (b - a)/c ( x - (a+b))

y = (b - a)/c ( x - (a+b)) + c.

The coordinates of Point P are:

(2a+0)/2, 2(c+ 0)/2

= (a, c)

The slope of the line AO

= (2c)/2a

= c/a

So The slope of the line PS = -a/c

Its equation is

y - c = -a/c(x - a)

y = -a/c(x - a) + c

So:

(b - a)/c ( x - (a+b)) + c

= -a/c(x - a) + c

(b - a)(x - a - b) + c^2 = -a(x - a) + c^2

(b - a)(x - a - b) = -a(x - a)

bx - ab - b^2 - ax + a^2 + ab = -ax + a^2

bx - ax + ax + a^2 - a^2 - ab + ab = b^2

bx = b^2

x = b = the x coordinate of S.

c). The point R has the same x coordinate as S So RS is perpendicular to OB.

What is X if X + 2/3 = 9/10?

laiz [17]

Answer:

$x=\frac{7}{30}$

Step-by-step explanation:

Given the following question:

$x+\frac{2}{3} =\frac{9}{10}$

In order to find the answer to this question we need to subtract 9/10 from 2/3. To do this we need to find the common denominator, and then subtracting the numerators.

$\frac{9}{10} -\frac{2}{3}$
$\frac{9}{10} \times3=\frac{27}{30}$
$\frac{2}{3} \times10=\frac{20}{30}$
$27-20=7=\frac{7}{30}$
$x=\frac{7}{30}$

Hope this helps.
