The slope of the graph is 4/5
<h3>How to determine the slope</h3>Using the formula
Slope = Δ y-axis / Δ x- axis
y2 = -4
y1 = 0
x2 = -5
x1 = 0
Slope =
Substitute the values into the formula
<em>Slope = </em>
Slope =
Slope =
Therefore, the slope of the graph is 4/5

We want the integral of the standard normal from -z to z to be 0.85. Let's look at some standard normal tables and pick the right one.
It's easy to find the Erf one, which is the integral of the unit normal from 0 to z. That will be exactly half of the integral from -z to z. So we look for the z value corresponding to a probability of 0.425 in that table and find
z = 1.44
Answer: 1.44
