No matter what type of polygon<span> you have, the </span>sum<span> of the </span>exterior angles<span> is ALWAYS equal to 360°. If you are working with a regular </span>polygon<span>, you can </span>determine<span> the size of EACH </span>exterior angle<span> by simply dividing the </span>sum<span>, 360, by the number of </span>angles.
Answer:
0.6 = 60% probability that he or she studies on a weeknight.
Step-by-step explanation:
We solve this question treating these events as Venn probabilities.
I am going to say that:
Probability A: Probability of a student studying on weeknights.
Probability B: Probability of a student studying on weekends.
Forty-two percent of students said they study on weeknights and weekends
This means that 
47% said they studied on weekends
This means that 
65% said they study either on weeknights or weekends.
This is 
If you were to pick one student at random, what is the probability that he or she studies on a weeknight?
This is P(A), and the equation used is:

Considering the values we have:



0.6 = 60% probability that he or she studies on a weeknight.
Answer:

Step-by-step explanation:
The midpoint of the line segment joining the points (10,7) and (negative 2,negative 7) is (4, 0)
<h3>
<u>Solution:</u></h3>
Given that line segment joining the points (10,7) and (negative 2, negative 7)
Thus the two points are (10, 7) and (-2, -7)
The midpoint of two points
and
is given as:


Substituting the values in formula, we get

Thus the midpoint of line segment is (4, 0)
