How does the diagram show that the slope between any
tensa zangetsu [6.8K]

The diagram shows that the triangles on the graph had similar ratios, as such their vertical heights to their horizontal are equivalent.

Option D is correct.

<h3>What is the slope of a graph?</h3>

The slope of a graph determines the steepness of the graph and it is the difference between two points on the y-coordinate(rise) and the difference between two points on the x-coordinate(run).

\mathbf{slope = \dfrac{rise}{run}}

\mathbf{slope = \dfrac{\Delta y}{\Delta x}}

\mathbf{slope = \dfrac{ y_2-y_1}{x_2-x_1}}

From the diagram attached, we can see that the triangles on the graph had similar ratios, as such their vertical heights(y-coordinates) to their horizontal (x-coordinates) are equivalent.

Given a normal distribution with a mean of 128 and a standard deviation of 15, what percentage of values is within the interval
tatyana61 [14]

Answer:

E. 99.7%

Step-by-step explanation:

Calculate each z-score.

z = (x − μ) / σ

z = (173 − 128) / 15

z = 3

z = (x − μ) / σ

z = (83 − 128) / 15

z = -3

You can use a z-score table, or use the empirical rule.

P(-3 < z < 3) = 99.7%.
