The slope is 3/2. Because the equation is given in slope intercept for y=mx+c and m is slope

Shkiper50 [21]

Individual : a male in the United States

Variable : income

Population : All males in the United States

Sample : 2500 males of which the information is collected

Parameter : Median income of males in the U.S

Statistic : Median income of the 2500 males sampled

Any quality, amount, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable.
A sample is a subset of units chosen to represent all the individuals in a population. Because just a portion of the population was counted, it is only a partial enumeration. To estimate the characteristics of the total population of interest, data from the sampled units is used.
A statistic is a numerical representation of a sample, whereas a parameter is a numerical representation of the entire population.

What is the equation of the line

konstantin123 [22]

Hello there!

The answer is B. $\frac{2}{7}$
-----------------------------------------------------------------------------------------------------

Explanation and Work:

We first must identify if the line goes through the origin or not.

The origin is (0, 0)

The line does go through the origin. This means that there is no y-intercept

The specific equation we would you use would be:

y = kx

K is the constant

We find this by finding the slope.

Slope is found by:

$\frac{y2 - y1}{x2 - x1}$

y2 = 2

y1 = 0

x2 = 7

x1 = 0

Now, let's plug in these numbers.

$\frac{2-0}{7-0} = \frac{2}{7}$

So, now let's plug he slope into our formula.

y = $\frac{2}{7} x$

So, our answer would be B.

I hope I helped!

Let me know if you need anything else!

Find the average rate of change of f(x)=2x-1 from x=-1 to x=2

MrMuchimi

The average rate of change from x = -1 to x = 2 is 2

<u>Solution:</u>

Given function is:

f(x) = 2x - 1

We have to find the average rate of change from x = -1 to x = 2

<em><u>The average rate of change is given as:</u></em>

$\text {Average rate of change}=\frac{f(b)-f(a)}{b-a}$

<em><u>The average rate of change from x = -1 to x = 2 is given by formula:</u></em>

$\text {Average rate of change}=\frac{f(2)-f(-1)}{2-(-1)}\\\\\text {Average rate of change}=\frac{f(2)-f(-1)}{3}$

<em><u>Find f(2) and f( - 1)</u></em>

<em><u>Substitute x = 2 in given function</u></em>

f(2) = 2(2) - 1 = 4 - 1 = 3

<em><u>Substitute x = -1 in given function</u></em>

f( - 1) = 2(-1) - 1 = -2 - 1 = -3

<em><u>Substitute the values in above formula,</u></em>

$\text {Average rate of change}=\frac{3-(-3)}{3}=\frac{6}{3}=2$

Thus average rate of change from x = -1 to x = 2 is 2
