Answer:
The palm tree is 12 m tall.
Step-by-step explanation:
1. The first to see is to consider this as triangle formed by the palm tree, the shadow, and the line from the top of the tree to the tip of the shadow to the tip the palm.
2. Assign variables to each distance in the triangle
Palm length= X
Shadow length= y
line from the top of the tree to the tip of the shadow to the tip the palm = Z
3. Describe the equation, reading the text:
(1) y=x-7
(2) z=x+1
(3)
(this last one is from pitagoras theorem)
4. We solve the system:
{y = x - 7, z = x + 1, z^2 = x^2 + y^2}
Solutions
x = 4, y = -3, z = 5
x = 12, y = 5, z = 13
Since the distance can't be negative. The answer is the palm tree is 12 meters tall.

So each chimpanzee Will get 2 bananas
1: theoretical probability for flipping a coin is thats because there are only 2 options and only one will happen theoretically you should get 50 out of 100 should be heads. but getting 41 out of 100 is a bit low
theoretically 50/100
in actuality 41/100
2. Part A: I believe the chance of hitting the black dot is closer to zero due to the amount of white background there is. There is a lot more white then black.
Part B: The probability of hitting the white is closer to 1 due to the greater amount of white on the target than the amount of black. There is a lot more white than black.
