Based on the family the graph below belongs to, which equation could represent the graph?

lord [1]

Answer-

Equation 1 is the equation which represents the graph.

Solution-

From the graph it can be noticed that, the function is a hyperbola. It is a rectangular hyperbola.

The general form of rectangular hyperbola is,

$xy=c^2$

Where c is a constant.

Equation 1 represents a function of rectangular hyperbola, with vertical asymptote as x=-2 .

Equation 2 represents an exponential function.

Equation 2 represents an cubic function.

Equation 2 represents logarithmic function.

Therefore, equation 1 is the equation which represents the graph.

IQ scores for adults age 20 to 34 years are normally distributed according to N(120, 20). In what range does the middle 68% of p

Ilya [14]

The required interval of the given normal distribution using the empirical rule is [100, 140].

The empirical rule formula (also known as a 68 95 99 rule formula) uses data from a normal distribution to determine the first, second, and third standard deviations, which, respectively, differ from the mean value by 68%, 95%, and 99%. Additionally, it shows that 99.9% of the data fall inside the third standard deviation range (either above or below the mean value). The empirical rule formula is described below with cases that have been resolved.

In the question, we are given that IQ scores for adults aged 20 to 34 years are normally distributed according to N(120, 20), and are asked for the range in which the middle 68% of people in this group score on the test.

N(120, 20) signifies a normal distribution with mean, μ = 120, and the standard deviation, σ = 20.

By the empirical formula, 68% of the data lies within one standard deviation from the mean.

Thus, the required interval is [μ - σ, μ + σ] = [120 - 20, 120 + 20] = [100, 140].
