Answer:
The Mean is 43
Step-by-step explanation:
If you need me to explain how I got there- I would be happy to ^w^
First, divide both sides by 3 to get log2x = 4/3.
Since you know a regular log has base 10, another way to write log2x = 4/3 is 10^(4/3) = 2x.
Then, divide both sides by 2.
x = 10.7722

First you need to find the total amount of trees by adding up all of the different trees:
420+160+300=880
Next you need to divide the amount of oak trees by the amount of trees in the woods:
160÷880=0.182 (rounded)
Finally to find the precentage we need to multiply the 0.182 by 100 to get the precentage of 18.2% oak trees.
Step-by-step explanation:
2(sp)=ln
6x+2=10x-6
8=4x
x=2
therefore sp=3×2+1=6+1=7
