Cooperation. The tribes that hunted together worked as a team. Men went on trips to hunt, leaving the women with the task of collecting berries and roots. Because of the fact that there wasn't any agriculture, tribes rarely came in contact with eachother, and when they did, it was easy to find somewhere else to get food.
I don't know exactly how to label these. I'll start from the left and go to the right. The formula for all of these questions is Sum = a(1 - r^n)/(1 - r)
Left
The complete series is 1 3 9 27 81 and just adding these as you see them, you get 1 + 3 + 9 + 27 + 81 = 121
Sample calculation
i = 1
3^(1 -1) = 1
i = 4
1 * 3^(4 - 1)=3^3 = 27 Just what the series says you should get.
Sum using formula
Sum = 1(1 - 3^5)/(1 - 3) = 1 * (1 - 243)/(1 - 3) = - 242/-2 = 121
Second from the left
Series: 3 6 12 24 48
Sum by hand = 93
Sample Calculation
i = 1
3*2^(1 - 1) = 1
i1 = 3
3 * 2^(3 - 1) = 3 * 2^2 = 3 * 4 = 12 which is what you should get.
Sum using formula
Sum = 3 (1 - 2^(5 - 1) / (1 - 2)
Sum = 3 (1 - 32) / - 1
Sum = 3(-31) / (- 1) = 93
Second from the right.
Series: 2 6 18 54
Sample Calculation
i = 1
t1 = 2* 3^(1 - 1) = 2*3^0 = 2*1 = 2
i = 4
t4 = 2 * 3^(4- 1)
t4 = 2 * 3^3
t4 = 2 * 27
t4 = 54 just as it should
Sum with formula
Sum = 2( 1 - 3^4) / ( 1 - 3)
Sum = 2(1 - 81)/ -2
Sum = 2( - 80) / - 2
Sum = 80
Entry on the right
Series: 1 2 4 8 16 32 64
Sum by hand: 1 + 2 + 4 + 8 + 16 + 32 + 64 = 127
Sample Calculation:
i = 1
2^(1 - 1) = 2^0
2 to the zero = 1
i = 6
t6 = 1( 2^6)
t6 = 1 * 2^6 = 64
Sum using the formula: 1*(1 - 2^7)/(1 - 2) = (1 - 128)/(-1 = 127

When it's just sitting alone, high in the night sky, the moon just looks"regular" sized. It's the Ebbinghaus effect
Answer:
False
Explanation:
The Gestalt principle of simplicity does not represent the tendency for individuals to arrange elements in a way that creates closure or completeness.
Therefore, the statement is false.
The Gestalt principle of simplicity is also known as the "Law of Simplicity".
According to this law, the whole is greater than the sum of its parts.
