Which of these numbers of simulations of an event would be most likely to produce results that are closest to those predicted by

LuckyWell [14K]

<span>C. 80 simulations would be the most likely to reproduce results predicted by probability theory. Due to the law of large numbers, as the number of trials increase, the actual ratio of outcomes will converge on the theoretical, or expected, ratio of outcomes.</span>

Find the slope of the given line, if it is defined. 2x + 1 = 0

svlad2 [7]

Given :

A line 2x + 1 =0 .

To Find :

The slope of the given line .

Solution :

We know , slope of line is given by the tangent of the angle between the x-axis and the line .

Now, for line 2x + 1 =0 i.e $x=\dfrac{-1}{2}$ .

The line is perpendicular to x-axis and cuts the x-axis at $\dfrac{-1}{2}$ .

Therefore , the angle between the line and x-axis is $90^o$ .

So , slope $m=\tan\ 90^o$ i.e undefined .

Therefore , the slope of given line is not defined .

Hence , this is the required solution .
