Answer:

(3,15)

Step-by-step explanation:

Rule 1

5x = y

Rule 2

x+12 = y

Set them equal

5x = x+12

Subtract x from each side

5x-x = x+12-x

4x= 12

Divide by 4

4x/4 = 12/4

x=3

5x=y

5*3 = y

15 = y

The solution is (3,15)

The diameters of Douglas firs grown at a Christmas Tree Farm are normally distributed with a mean of 4 inches and a standard dev
leva [86]

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.

z=\frac{x-\mu}{\sigma}=\frac{5-4}{1.5}=0.67

P(x>5)=P(z>0.67)=0.25  

The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
