Given:

We get the points (0,6), (3,32), and (12,770) from the given table.

1.

Let y be the number of the rabbit and x be the number of months.

Consider the regression equation of the form.

y=a(b)^x

Substitue x=0 and y=6 in the equation, we get

6=ab^0

a=6

Substitue x=12 and y=770 in the equation, we get

770=ab^{12}

\text{ Substitute }a=6\text{ in the equation, we get}

b^{12}=\frac{770}{6}

b^{}=\sqrt[3]{\frac{309}{32}}undefined

10n -11 =3 + 4n + 6n​
MrRissso [65]

Answer:

10n -11 =3 + 4n + 6n​

10n - 10n -11 =3-3 + 4n + 6n​

-11 - 3 = -10n + 4n + 6n

-14= -10n + 10n

-14 = n

Step-by-step explanation:

10n -11 =3 + 4n + 6n​

10n - 10n -11 =3-3 + 4n + 6n​

-11 - 3 = -10n + 4n + 6n

-14= -10n + 10n

-14 = n
