Step-by-step explanation:

You add the total number of balls, which is 10. and then it is asking for brown balls and looking at the equation you know there are 3. so 3/10 is .30 which is 30%

The function f(x)=3 (x+6)^2+8 is shifted 4 units up and 3 units right to form another function g(x). What is g(x)?

iVinArrow [24]

Answer:

$g(x) = 3\cdot (x+3)^{2}+12$

Step-by-step explanation:

There are two operations involved:

Vertical translation:

$f'(x) = f(x) \pm c,\,c\in \mathbb{R}$ (1)

Note: Positive sign represent a translation upwards.

Horizontal translation:

$f'(x) = f(x\pm c), x\in \mathbb{R}$ (2)

Note: Positive sign represent a translation leftwards.

Then, the new function must be:

$g(x) = f(x-3)+4$

$g(x) = 3\cdot (x+3)^{2}+12$

Given the data shown below, which of the following is the best approximation of the coefficient of determination (r^2)

HACTEHA [7]

The coefficient of determination can be found using the following formula:

$r^2=\mleft(\frac{n(\sum ^{}_{}xy)-(\sum ^{}_{}x)(\sum ^{}_{}y)}{\sqrt[]{(n\sum ^{}_{}x^2-(\sum ^{}_{}x)^2)(n\sum ^{}_{}y^2-(\sum ^{}_{}y)^2}^{}}\mright)^2$

Using a Statistics calculator or an online tool to work with the data we were given, we get

So the best aproximation of r² is 0.861
