Answer:
Mean =25.78
Median =20
Step-by-step explanation:
given that the following list contains the average annual total returns (in percentage points) for 9 mutual funds. The mutual funds appear in an online brokerage firm's "all-star" list.
40, 30, 6, 10, 30, 18, 15, 20, 36
Let us find the sum of these 9 entries
Sum = 205
a) Mean = 
b) Median of this data set is the middle entry after arranging in ascending order
Here it would be the 5th entry
6,10, 15, 18,20, 30, 30, 36, 40
Median = 20

Answer:
y= -1/15x + 16/15
Step-by-step explanation:
When two lines are perpendicular to each other that means their slopes are the negative reciprocals of each other.
So that means if a line has has a slope of 6, a line perpendicular to that line will have a slope of -1/6.
(a reciprocal is when the fraction is flipped over)
In this case, the negative reciprocal of 15 would be -1/15. So the slope of the line that is perpendicular would be -1/15.
The equation we would have so far for that line would be: y=-1/15x+b
Now we have to find the 'b' or the y intercept, which we can get by plugging in the point that was given (1,1), which is on that line.
Which gives us 1=-1/15(1)+b.
1=-1/15+b
1+1/15=b
Then you solve for b and get b= 16/15.
The equation of the line that is perpendicular to the given line is y= -1/15x + 16/15.
Answer:
a. Point.
b. Vertex.
c. Line.
d. Line segment.
e. Ray.
Step-by-step explanation:
a. <u>Point</u>: a location, has no dimension. Also, a point doesn't have a size i.e no length, depth, breadth or height.
b. <u>Vertex</u>: is the common endpoint of two segments or rays that form the "corner" of an angle.
c. <u>Line</u>: is an infinite number of points extending in opposite directions that has only one dimension.
d. <u>Line segment</u>: is part of a line that has two endpoints.
e. <u>Ray</u>: is part of a line that has one endpoint and continues in one direction infinitely.
