Answer:

<em>Probability ≈ 0.0714</em>

Step-by-step explanation:

Consider permutation and combination;

Total Combinations - 8C4,\\8C4 = 8! / 4! * ( 8 - 4 )!,\\8 * 7 * 6 * 5 / 4!,\\\\Total Combinations = 70,\\\\Combinations of Dance Classes - 5C4,\\5C4 = 5! / 4! * ( 5 - 4 )!,\\5 * 4 * 3 * 2 * 1 / 4 * 3 * 2 * 1,\\\\Dance Classes = 5,\\\\Probability - 5 / 70 = 0.0714,\\Conclusion; Probability = ( About ) 0.0714

Find the absolute maximum of (x^2-1)^3 in the interval [-1,2]
Blizzard [7]

Let <em>f(x)</em> = (<em>x</em> ² - 1)³. Find the critical points of <em>f</em> in the interval [-1, 2]:

<em>f '(x)</em> = 3 (<em>x</em> ² - 1)² (2<em>x</em>) = 6<em>x</em> (<em>x </em>² - 1)² = 0

6<em>x</em> = 0   <u>or</u>   (<em>x</em> ² - 1)² = 0

<em>x</em> = 0   <u>or</u>   <em>x</em> ² = 1

<em>x</em> = 0   <u>or</u>   <em>x</em> = 1   <u>or</u>   <em>x</em> = -1

Check the value of <em>f</em> at each of these critical points, as well as the endpoints of the given domain:

<em>f</em> (-1) = 0

<em>f</em> (0) = -1

<em>f</em> (1) = 0

<em>f</em> (2) = 27

So max{<em>f(x)</em> | -1 ≤ <em>x </em>≤ 2} = 27.

Determine the domain of the following graph​
blsea [12.9K]

Answer:

Domain: [-8. 4]

General Formulas and Concepts:

<u>Algebra</u><em><u> </u></em><u>I</u>

  • Domain is the set of x-values that can be inputted into function f(x)
  • Interval Notation

Step-by-step explanation:

From the graph, we can see that our x-values span from -8 to 4. Since both are closed dot, they are inclusive in the domain:

[-8. 4] or -8 ≤ x ≤ 4
