Answer:
Scalene triangle
Step-by-step explanation:
Coordinates of the vertices of the triangle are,
W(-7, 1), X(0, -4) and Y(2, 3)
We will use the formula to get the distance between two points.
d =
WX =
=
WY =
=
XY =
=
=
Since, measures of all three sides of the triangle are not equal, given triangle will be a scalene triangle.
Answer:
4(7y-8)
Step-by-step explanation:
15 is 60 percent of 25. 15x100/60 and it should be 25.
The negative correlation between IQ and age guarantees that all younger people have higher IQ's than older people.
The strength of the linear link between two separate variables, x and y, is shown by correlation coefficients. A positive association is shown by a linear correlation coefficient larger than zero. Indicating a negative association is a value less than zero. The two variables x and y do not have any relationship when their values are 0, to sum up.
A positive correlation indicates that both variables move in the same direction when the correlation value is higher than 0. When is 1, it denotes a complete positive association between the two variables under comparison; when one variable rises or falls, the other one rises or falls in the same direction and by the same amount.
When the correlation coefficient is less than 0, there is a negative (inverse) correlation. This suggests that both variables are moving in the obverse direction. In essence, any reading between 0 and -1 denotes an opposing movement of the two securities. The connection is said to as fully negatively correlated when is equal to -1.
Thus, the negative correlation between IQ and age guarantees that all younger people have higher IQ's than older people.
