Which statements are true about these lines? Select three options.
shepuryov [24]
RS is perpendicular to MN and PQ.


We can use the slopes of these lines to determine the answer.
Slope is given by the formula
m=.

Using the coordinates for M and N, we have:
m=.

Since PQ is parallel to MN, its slope will be as well, since parallel lines have the same slope.

Using the coordinates for points T and V in the slope formula, we have
m=.

This is not parallel to MN or PQ, since the slopes are not the same.
We can also say that it is not perpendicular to these lines; perpendicular lines have slopes that are negative reciprocals (they are opposite signs and are flipped). This is not true of TV either.

Using the coordinates for R and S in the slope formula, we have
m=. Comparing this to the slope of RS, it is flipped and the sign is opposite; they are negative reciprocals, so they are perpendicular.

viktelen [127]

Answer:

The correct option is C.

Step-by-step explanation:

Consider the provided information.

Four conditions of a binomial experiment:

There should be fixed number of trials

Each trial is independent with respect to the others

The maximum possible outcomes are two

The probability of each outcome remains constant.

Now, observe the provided options:

Option A and B are not possible as they doesn't satisfy the conditions of binomial experiment which is there must be fixed number of trials.

Now observe the option C which state that there must be fixed number of trials, it satisfy the condition of a binomial experiment.

Therefore, the correct option is C.
