The inside angles of a 5 sided figure needs to equal 540 degrees.
The total of the given angles is: 131 + 108 + 107 + 110 = 456.
Subtract the total from 540 for x.
X = 540 - 456 = 84 degrees.
Add the numbers, then divide your new number by how many original numbers there are. 7 + 9 = 16, then 16 / 2 = 8, so your mean is 8.
Answer:
4 + 9i
Step-by-step explanation:
A complex number consists of a real part and an imaginary part, that is
z = x + yi ( x is the real part and yi the imaginary part )
A complex number does not exist in the set of real numbers.
Answer:
<h2>C) r = − 1</h2>
Step-by-step explanation:
In the graph, you can observe that all five points are perfectly lined up on a straight line, which is decreasing, because each points is lower than the previous one.
This situation represents a coefficient of correlation of -1, which means there's a strong negative correlation between variable.
Once again, graphically, this strong negative correlation can be deduct from the behaviour of the data, which is clearly decreasing with a straight line behaviour. In other words, the line that best fits is almost unique.
Therefore, the right answer is C.
