The correct answer is option D.

F(G(x)) denotes the composition of the two functions F(x) and G(x). The composition of two functions result in x, if the two functions are inverses of each other. So in this case F(x) and G(x) will be the inverse of each other. So option D is the correct answer.

Hi!

The answer should be third option.

$20+4j\ge 2\left(j+20\right)$

$20+4j\geq 2j+40$

$20+4j-20\geq 2j+40-20$

$4j\geq 2j+20$

$4j-2j\geq 2j+20-2j$

$2j\geq 20$

$\frac{2j}{2}\geq \frac{20}{2}$

$Answer ---> j\geq 10$

Explanation: First you had to subtract by the 20 from both sides. Then simplify it gave us 4j ≥ 2j+20. You can also subtract by the 2j from both sides. Then simplify its going to be 2j≥20. Next, you can also divide by 2 from both sides, and it gave us the answer is j≥10 is the right answer. Hope this helps! And thank you for posting at here on Brainly. And have a great day. -Charlie

X^2-8x+16 divided by ax-4x numerator

Vedmedyk [2.9K]

Answer:

Given:

1). $x^2-8x+16$ divided by $x-4$

⇒ $\frac{x^2-8x+16}{x-4}$

⇒ $\frac{x^2-2\times x\times 4+4^2}{x-4}$

By factorising numerator by using identity, $(a-b)^2=a^2-2\times a \times b +b^2$

⇒ $\frac{(x-4)^2}{x-4}$

⇒ $\frac{(x-4)\times(x-4)}{x-4}$

⇒ $x-4$ {Answer}

2). $3x^2y$ divided by $6xy^2$

⇒ $\frac{3x^2y}{6xy^2}$

⇒ $\frac{3\times x\times x\times y}{6\times x\times y\times y}$

⇒ $\frac{x}{2y}$ { Answer}

. Choose the correct means and standard deviations for the Sincere and Insincere conditions. Make sure to round to two decimal p

tensa zangetsu [6.8K]

Answer:

C. The rudely disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the politely disagrees condition has a mean of 3.82 and standard deviation of 0.97

Step-by-step explanation:

The given data is

x` Std. Dev

R. disagrees 4.16 0.854

P. disagrees 3.82 0.967

From this data we see that the R. disagrees has a mean of 4.16 and standard deviation of 0.854

while

the P. disagrees has a mean of 3.82 and standard deviation of 0.967.

Same figures are given only in option C because

Rounding 0.854 gives 0.85

Rounding 0.967 gives 0.97

So only option C is the best choice.

C. The R. Disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the P. Disagrees condition has a mean of 3.82 and standard deviation of 0.97
