From left to right:
Negative, positive, none, nonlinear
1 is negative bc it has a negative slope
2 is positive because it has a positive slope
3 has no correlation because there is no pattern
4 is no linear because it’s not in a line, essentially. (This would be a parabola)
:)
Answer:
B
Step-by-step explanation:
A is missing a combination AR and has repeats such as AG and GA. Since the order of the sides doesn't matter, AG and GA are the same thing.
C is missing many combinations, it only has 4
D has two of the same sides. The question states "you can choose two <em>different </em>sides" so something like AA is not an option
We can use the process of elimination to conclude the answer is B.
Answer:
7.875
Step-by-step explanation:
Answer: There are 140 adults and 40 children.
Step-by-step explanation:
Let 2x = Number of children
7x = Number of adults.
As there are 100 more adults than children.
That means, 

Number of children = 2 (20)=40
Number of adults = 7(20) = 140
Hence, there are 140 adults and 40 children.
Answer:
1.
Step-by-step explanation:
7 * t = 7t
7 * 2 = 14
7(t+2) = 7t + 14
