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%

Answer:
Step-by-step explanation:
-5x + (x -1) = -21
-4x = -20
x = 5
Answer:
3 : 2
Step-by-step explanation:
The ratio of pancake mix to milk is ...
pancake mix : milk = (9 cups) : (6 cups) = 9 : 6 = 3 : 2
The equation of the line will be y = 2x - 2.
<h3>What is an equation of the line?</h3>
A linear equation with a degree of one is referred to as a line equation. Two variables, x, and y are present in the equation of the line. The third parameter is the line's slope, which indicates the line's elevation.
The general form of the equation of the line is given as:-
y = mx + c
Given that the equation of the line is passing through the point ( -2,0) and the slope of the line is 2.
The equation of the line will be calculated as:-
y = mx + c
-2 = 0 + c
c = -2
y = mx + c
y = 2x - 2
Therefore, the equation of the line will be y = 2x - 2.
