Answer:
a. Mean
a. 79 points is an outlier, and the mean is most responsive to outliers.
Step-by-step explanation:
17, 14, 30, 24, 21, and 14
Let's calculate the measure of central tendency of the numbers first.
Mean = 120/6
Mean = 20
For Median
Let's arrange the numbers in ascending order
14,14,17,21,24,30
The median is 17 and 21
Median value =( 17+21)/2
Median = 38/2
Median = 19
Mode = 14.
After 79 was added.
Mean =( 120+79)/7
Mean = 199/7
28.43
For Median
14,14,17,21,24,30,79
Median= 21
Mode = 14
The value that changed the most was the mean value.
Answer:
d) ≤
Step-by-step explanation:
1/6 divided by 4 = 1/24
so each person would get 1/24 of that cake
(just wondering what would the flavor of the cake be??)
25% 3/10 1/3 and 37.5%
.25,.30,.33,.375
Answer:
A rule of polygons is that the sum of the exterior angles always equals 360 degrees. Since it is a regular octagon, so each of the interior angles of octagon are equal. ((n-2)*180)/n where n is the number of sides of the polygon.for example in case n=8 for an octagon, so we get:
((8-2)*180)/8 => (6*180)/8 => 1080/8 = 135 degrees. This means that each interior angle of the regular octagon is equal to 135 degrees.
Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees. (180 - 135 = 45). Remember that supplementary angles add up to 180 degrees.
And since there are 8 exterior angles, we multiply 45 degrees * 8 and we get 360 degrees.
This technique works for every polygon, as long as you are asked to take one exterior angle per vertex.
