X is equal to 4 because when you simplify the right side of the equal sign you will get 19. Then when you simplify the left side of the equal sign you will get 4x+3. Next you would want to subtract 3 from both sides giving you 4x=16, which you would then divide by 4 on both sides giving you an answer of x=4
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.
