Kevin=k
Daniel=d
k=4d
k=d+6
4d=d+6
4d-d=6
3d=6
d=2
k=d+6
k=2+6
k=8
Daniel is 2
Kevin is 8
The correlation coefficient (r) of the height and weight is 0.40391008.
Rounded, It will be 0.4
That means that the correlation between the height and weight is a positive weak correlation.
Answer:
The table that represents the nonlinear function is the one where the x-values are -7, -5 and 0 and the y-values are -3, 0 and 3.
Step-by-step explanation:
In order for a table to represent a linear function, there needs to be a consistent change in y-values divided by the change in x-values. For example, for any two points on the table when we subtract two y-values and divide by the number we get when we subtract two x-values, this change should be represented throughout the table. So, in the case of the other three tables, when we choose two points from the table, such as (-5, 7) and (-2,6) and put them into an equation (y2-y1/x2-x1) or (6-7)/(-2-(-5)) we would get a change of -1/3. However, when we apply this concept to the table where x-values are -7,-5, and 0, we see that the change is not consistent between points, so the function must be nonlinear.
If you
3 x 3 / 8
you
3× 3 = 9
in you put
9/8
Let’s first start by realizing that it is perimeter, so it will have to have two different numbers. 56 divided by 4 is 14, this would make it a square. So then you start plugging in numbers.
L W
15 13
17 11

Do this again until you get to a point where the Length is 3 times more than the width.
19. 9
21. 7

The length is three times more than the width so the dimensions of the room is 21 by 7.
21+21+7+7=56 meters
