What is the exponential regression equation that fits these data?

zlopas [31]

Answer:

Option B) $y = (1.31)(2.8^{x})$ is the correct option.

Step-by-step explanation:

<em>Exponential function is the one where, a constant is raised to the power of x, a independent variable.</em>

Here, only option B and D are such exponential functions, while option A is linear and option C is quadratic in nature.

Now, to verify which option is correct, we will input the values and check which has the least difference between the given values.

Or we can use the cost function,

$J = \frac{((y(i))-y)^2}{2m}$ , to find which function has the least error.

By applying the above results,we find Option B is correct.

Amanda has 745 blueberries. She separated the blueberries into 5 equal groups. How many blueberries are in 2 of the groups?

Anit [1.1K]

Answer:

298

Step-by-step explanation:

5 equal groups of 745 would have 149 blueberries. You want to find how much is in 2 groups so you add 2 groups together, which is 149 + 149. That equals 298.

$\dfrac{ \dfrac{x+3}{4x^2-16} }{ \dfrac{2x^2+10x+12}{2x-4} }$

-----------------------------------------------------------------------------------
Write the divide fraction horizontally:
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4x^2-16} \div \dfrac{2x^2+10x+12}{2x-4}$

-----------------------------------------------------------------------------------
Factorise the numerators and denominators when possible:
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4(x+2)(x-2)} \div \dfrac{ 2(x + 3) (x + 2)}{2(x-2)}$

-----------------------------------------------------------------------------------
Convert the divide fraction to multiplication fraction
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4(x+2)(x-2)} \times \dfrac{2(x-2)}{2(x+3)(x+2)}$

-----------------------------------------------------------------------------------
Cancel the factors
-----------------------------------------------------------------------------------
$= \dfrac{1}{4(x+2)} \times \dfrac{1}{(x+2)}$

-----------------------------------------------------------------------------------
Combine to single fraction
-----------------------------------------------------------------------------------

$= \dfrac{1}{4(x+2)^2}$
