1. How do you find the absolute deviation of a value from the mean of the data set?

1 answer:

7 0

Here's how to calculate the mean absolute deviation. Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. Step 4: Divide the sum by the number of data points.

Answer:

option 2 : 754 in³

Step-by-step explanation:

diameter = 8 => radius, r = 4 inches , h = 15 inches

$volume = \pi r^2 h$

$=\pi \times 4^2 \times 15 \\\\=753.9 \ in^3\\\\= 754 \ in^3$

Use the calculator to graph the function y = 2x2 25x + 3. What are the coordinates of the turning point of the graph to the near

The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

$y = ax^2 + bx + c$

The vertex is given by:

$(x_v, y_v)$

In which:

$x_v = -\frac{b}{2a}$

$y_v = -\frac{b^2 - 4ac}{4a}$

In this problem, the function is given by:

y = 2x² + 25x + 3.

Hence the coefficients are a = 2, b = 25, c = 3, then the coordinates of the vertex are given as follows:

$x_v = -\frac{25}{2(2)} = -6.25$

$y_v = -\frac{25^2 - 4(2)(3)}{4(2)} = -75.13$

The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).

What is the area of the figure below?

Arada [10]

Answer:

15x^9

Step-by-step explanation:

A=l x w

5x^4 times 3x^5 is basically 3*5*x^4*x^5

when you multiply exponents with the same base, you add the exponents, so it becomes 15x^9
