The equation of a straight line is given by:
y = mx + c
where m is the slope and c is the y-intercept.
From the given graph, the y-intercept is 1.
The slope of a straight line is given by:
Where
and
are two points on the line.
From the graph, (0, 1) and (14, 8) are two points on the line, thus:
Therefore, the equation representing the graph is
Answer:
Option D) 108 degrees
Step-by-step explanation:
We are given the following in the question:
A regular pentagon.
Thus, all the angles of the pentagon are equal.
Angle sum property of pentagon:
- In a pentagon, the sum of all the interior angle of a pentagon is 540 degrees.
Measure of each angle =
Thus, the measure of each angle on the sign is 108 degrees.
Option D) 108 degrees
Answer
Cluster sampling. See explanation below.
Step-by-step explanation:
For this case they not use random sampling since we are selecting people from flights. Because we select just 5 random flights.
Is not stratified sampling since we don't have strata clearly defined on this case, and other important thing is that in order to apply this method we need homogeneous strata groups and that's not satisfied on this case.
Is not convenience sampling because they NOT use a non probability method in order to select the people from the flights.
So then the only possible method is cluster sampling since we have clusters clearly defined (Passengers from the airlines), and we satisfy the condition of homogeneous characteristics on the clusters and an equal chance of being a part of the sample, since we are selecting RANDOMLY, the 5 flights to take the information.
5+1 times 10=???
order of operations
multiplcation comes before addition
so yes, multiply first
5+1 times 10=5+10=15
