Answer:
The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
Step-by-step explanation:
In this problem we have a normal ditribution with mean of 4.0 in and standard deviation of 1.5 in.
The proportion of the trees that are expected to have diameters greater than 5 inches is equal to the probability of having a tree greater than 5 inches.
We can calculate the z value for x=5 in and then look up in a standard normal distribution table the probability of z.
The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
Answer:
The graph is attached below.
Step-by-step explanation:
First, we want to isolate the "x" term from the equation. We do this by subtracting "2" from both sides.
This gives us x is greater than -1. So, we can graph:
Answer:
false: the event will never occur; the event will definitely occur; the event is likely to occur
true: there is a small chance that the event will occur
Step-by-step explanation:
Simplify:
8/36=4/18=2/9=0.22222(repeating)
Your answer would be 2/9 or 0.22222(etc.).
I hope this helps :)
Hey there! :D
Plug in x for 2.
4x= 4(2)
x^4= (2^4)
Evaluate.
4x= 8 2^4= 16
Now, subtract the difference.
16-8= 4
The difference is 4.
I hope this helps!
