It would be -1/2 simplified and 12/-6 not simplified
Answer:
Step-by-step explanation:
Given that:
The coordinates of the vertices of a triangle are given as:
, , and .
To find:
The coordinates of the centroid of the triangle.
Solution:
The coordinates of the centroid of a triangle is given as:
Where are the coordinates of the vertices of the triangle.
As per the given values, we have:
Putting the values,we can find the coordinates of centroid as:
Therefore, the coordinates of the centroid is:
Answer:
The value of the proportionality constant (y to x) is: 3/10
Step-by-step explanation:
We know the slope of any graph where 'y' varies directly with 'x' gives us the constant of proportionality 'k'.
i.e. y = kx
and k = y/x
Given the points
We know that the proportionality constant (y to x) is:
k = y/x
For the point (100, 30)
k = 30/100=3/10
For the point (300, 90)
k = 90/300=3/10
For the point (500, 150)
k = 150/500=3/10
As the value of proportionality constant (y to x) is the same.
i.e. k = 3/10
Thus, the value of the proportionality constant (y to x) is: 3/10
Or........
We already know 12 x 12 =144. So all you could do isis add 12 to 144 to get your complete answer. Which is:
12 x 13 = 156
The sampling method that is most bias is:
