According to empirical rule, the area under the normal distribution or "bell-shaped curve", when plotted as a function of the z-parameter can be defined in terms of percentages.
The z-parameter (or z-score) is defined as
where
x = value of random variable,
μ = the mean,
σ = standard deviation,
The total area under the curve = 1.
The curve below shows that within 2 standard deviations from the mean, the total area under the curve is 95% of the total area.
Answer: 95%

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:
Step-by-step explanation:
We will use the slope intercept form of the equation to make an equation of the given line
The slope-intercept form is:
Here m is the slope and b is the y-intercept
Given
m = 2/3
Putting the value of slope
The y intercept is -5 so we will put in the equation
