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: i think you are supposed to subb in the x and h for something i just dont know what it is im not that smrt sorry i would thing it is 4 for x then the one would turn negative because in the equation it is subtraction so just do 4(4)^2+4-1 for the first one
the second one just do the same thing sub in the same numbers so it would be 4(4+1)-4(4)/1 i think it will get your answer brainliest plz
