So the answer is : 5y + 10 = 6y + 3
5y - 6y +10 = 3
-y= 3-10
-y= -7 Now you are looking for y not -y so you have to multiply or divide both side by (-1). It will be :
(-1) -y = (-1) -7
So:
Y = 7 Final answer.
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.
