Hi there!
The question sounds really complex, but the mathematical operations behind it is figuratively simple. Here, we are told to find 19 (18.7 rounded up is 19) percent of 1,000. To do this, we can set up a proportion to model the whole scenario.
\frac{x}{1000} = \frac{19}{100}
Now, just solve for x by cross multiplying and simplifying.
\frac{x}{1000} = \frac{19}{100}

100x = 19000
x=190
Therefore, 190 people out of 1,000 people leave out pertinent information on their IRS forms. Hope this helped and have a terrific day!

Given ΔABC with A(–4, –2), B(4, 4), and C(18, –8), write the equation for the line containing median segment The term is line se
Monica [59]
Here we want to find the equation of the line containing the median CP.

P, being the midpoint of AB can be found using the midpoint formula as:

\displaystyle{ P=( \frac{-4+4}{2} ,  \frac{-2+4}{2} )=(0, 1).


The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

\displaystyle{ m= \frac{y_2-y_1}{x_2-x_1}= \frac{-8-1}{18-0}= \frac{-9}{18}= \frac{-1}{2}.


Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

y-1= \frac{-1}{2}(x-0)\\\\y= -\frac{1}{2}x+1.


Answer: y=-\frac{1}{2}x+1
