posledela

It would be mean. The mean is the average that is you are looking for, since she wants a summerization of all the values in the data set. To find the mean (average) add all the numbers and then divide by the amount of numbers.

A function is created to represent the costs of living per person in the family. What restrictions would be made to the domain?

Nitella [24]

Let

x-------> the number of persons in the family

f(x)------> the function represent the cost of living

we know that

The domain of the function would only include positive integers, because the number of persons can not be negative or a fraction

The range of the function would only include positive numbers, because the cost can not be negative

therefore

<u>the answer is the option B</u>

The domain would only include positive integers.

Given f(x)= 3x+2, what is the Inverse Function?

Grace [21]

Answer:

Step-by-step explanation:

For this case we must determine the inverse of the following function:

$f(x)=3x-2$

Step 1:

We would write

$y=f(x)$ or $y=3x-2$

Step 2:

We clear x:

$y+2=3x$

$\frac{y+2}{3}=x$

Step 3:

"x" and "y" are exchanged:

$y=\frac{x+2}{3}$

The inverse is:

$f^{-1}(x)=\frac{x+2}{3}$

$\bf \textit{Amount for Exponential Decay using Half-Life} \\\\ A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &2.5\\ t=\textit{elapsed time}\dotfill &24\\ h=\textit{half-life}\dotfill &14 \end{cases} \\\\\\ A=2.5\left( \frac{1}{2} \right)^{\frac{24}{14}}\implies A=2.5\left( \frac{1}{2} \right)^{\frac{12}{7}}\implies A\approx 0.761883533878$
