Answer:
Option A- One
Step-by-step explanation:
Given that : The sides of the triangle measuring 6cm, 2cm and 7cm.
We are using : Triangle inequality
The sum of the length of the two sides should be greater than the length of the third side.
So, when we apply this theorem in 6cm,2cm and 7cm
6+2=8>7 , 7+2=9>6 , 7+6=13>2
It satisfy all three possible sets.
Therefore, the given values follows the triangle inequality.
Hence one triangle can be formed.
Therefore, option A is correct.
Answer:
5 2/5
Step-by-step explanation:
(2 1/4) / x = (1 1/2) / (3 3/5)
so
x = (2 1/4) * (3 3/5) / (1 1/2)
Answer:
B(-3, -3)
Step-by-step explanation:
If a point O(x, y) divides line segment XY in the ratio of n:m and the endpoints of the segment are 
, the coordinates of O is:
Given that A(6, -6) and C(-6, 2). Pont B is on AC such that:
AB = (3/4)AC
AB/AC = 3/4
Therefore point B divides the line AC in the ratio of 3:1. Let point B be at (x, y), therefore:
Therefore the location of B is at (-3, -3)
This is a very good visual representation. Whether it is the best, or not, depends on the purposes:
First, you can see right away where the top 25% (4th quartile) scored by looking at the right hand whisker.
Second, you get two measures of variation for the data, the range and the interquartile range. Finally, by looking at the left whisker, you can see that most of the variation comes from the bottom quartile: 3/4 of the students scored between 80 and 100, while 1/4 scored between 80 and 50.
As a teacher, I would want more detail about the bottom quartile. It might be that one student scored 50 and everyone else scored between 70 and 80. But I wouldn't need to have it graphically represented. This graph shows me that the class overall is in good shape: The median is close to 90. But there is at least one student, and up to 25 % of the class who did poorly on an exam that otherwise looks very easy.
