It’s going to be negative infinitely, infinitely.
Answer:
The area of the triangle is of 6 units squared.
Step-by-step explanation:
Representation of the triangle:
This triangle, in the cartesian plane, has the vertices at these following points.
(7,7)
| -> 4 units down
(7,3) --- (10,3) -> 3 units to the right.
This can be represented as a right triangle with sides 4 and 3.
Area of a right triangle:
The area of a right triangle is the multiplication of the lengths of its sides divided by 2. So
4*3/2 = 12/2 = 6.
The area of the triangle is of 6 units squared.
Answer: Option D
D. 0.92
Step-by-step explanation:
The correlation coefficient "r" is a number between -1 and 1 that indicates how related are two variables X and Y.
The stronger the nearest correlation is, the value of r a -1 or a 1.
A negative correlation indicates that when X increases Y decreases.
A positive correlation indicates that when X increases Y increases.
A correlation close to zero implies that there is very little correlation of the variables. When this happens, the points are scattered in the graph.
In this case you can see in the graph that the points are not scattered, but aligned. You can also observe that when X increases Y increases also.
This allows us to conclude that the correlation is strong and positive. Therefore the correct option is option D.
Listing out a few elements of the set of perfect squares, we get the following values
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100, ...}
we can stop there because 82 is between 81 and 100
So if x^2 = 82, then x^2 is between 81 and 100 meaning
81 < x^2 < 100
apply the square root to all sides of the compound inequality and we get
9 < x < 10
So the square root of 81 is between 9 and 10
Answer: the value falls between 9 and 10
