**Step-by-step explanation:**

**Answer:**

d) 2.3 to 3.5

**Step-by-step explanation:**

**In this problem, we have that:**

The mean is 2.9

The standard deviation is 0.6

**One standard deviation below the mean**

This is the mean subtracted by one standard deviation.

So this is 2.9 - 0.6 = 2.3

**One standard deviation above the mean**

This is one standard deviation added to the mean.

So this is 2.9 + 0.6 = 3.5

**So the correct answer is:**

d) 2.3 to 3.5

Answer:

36

Step-by-step explanation:

Area of a triangle = (bh)/2

Where b = base length and h = height

Given base length: 18ft

Given height: 4ft

This being known let's define the variables

b = 18

h = 4

Now to find the area we simply plug in these values into the formula

Area = (18)(4)/2

Simplify multiplication 18 * 4 = 72

Area = 72/2

Simplify division

Area = 36
