Answer:

Parameter because the value is a numerical measurement describing a characteristic of a population.

Step-by-step explanation:

A parameter tells you something about the entire population.This means that you will know the "something" after asking every person in that group.In this question, the study was conducted for all 1580 seniors, and it was found that a parameter of 40% own a television.

Write an equation in slope-intercept form for the following line:<br> (-14.1) and (13,-2)
vesna_86 [32]

Answer:

y=-\frac{1}{9}x-\frac{5}{9}

Step-by-step explanation:

(-14,1)(13,-2)

Use the slope-intercept formula:

y=mx+b

m is the slope and b is the y-intercept. Use the slope formula first:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{rise}{run}

Rise over run is the change in the y-axis over the change in the x-axis. Plug in the coordinates:

(-14(x_{1}),1(y_{1}))\\(13(x_{2}),-2(y_{2}))

\frac{-2-1}{13-(-14)}

Simplify parentheses (two negatives makes a positive):

\frac{-2-1}{13+14}

Simplify:

\frac{-3}{27} =-\frac{3}{27}=-\frac{1}{9}

The slope is -\frac{1}{9}. Insert into the equation:

y=-\frac{1}{9}x +b

Now, to find the y-intercept, take one of the points and substitute for the x and y values of the equation:

(13,-2)\\-2=-\frac{1}{9} (13)+b

Solve for b, the y-intercept. Simplify parentheses:

-\frac{1}{9}*\frac{13}{1}=-\frac{13}{9}

-2=-\frac{13}{9} +b

Add -\frac{13}{9}  to both sides:

-2+\frac{13}{9}=-\frac{13}{9} +\frac{13}{9}  +b\\\\-2+\frac{13}{9} =b

Simplify:

-\frac{2}{1} +\frac{13}{9}\\\\-\frac{18}{9}+\frac{13}{9}\\  \\b=-\frac{5}{9}

The y-intercept is -\frac{5}{9} . Insert this into the equation:

y=-\frac{1}{9} x-\frac{5}{9}

Finito.

25x=2544 what does x represent
Georgia [21]
Hey there! 

Firstly, we are going to divide by 25 on each of your sides because it paired off with a variable

Here's what I meant! 

\frac{25x}{25} =  \frac{2,544}{25}

We would have to cancel out the: \frac{25x}{25} because it gives us 1

Answer: x =  \frac{2,544}{25}

Good luck on your assignment and enjoy your day!
