Answer:

<em>Probability ≈ 0.3571</em>

Step-by-step explanation:

Consider the steps below;

$Total Number of Outcomes - 9C4,\\9 ! / 4 ! * ( 9 - 4 ),\\9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / 4 * 3 * 2 * 1 * 5 * 4 * 3 * 2 * 1,\\\\Total Outcomes = 126,\\\\Number of Outcomes - 3C2 * ( 6C2 ),\\3C2 = 3,\\6C2 = 15,\\\\Number of Outcomes = 3 * 15 = 45,\\\\Probability; 45 / 126 = ( About ) 0.3571$

<em>Solution; Probability ≈ 0.3571</em>

Factor the following equations to find the zeros of the equation.

irina1246 [14]

The zeroes of the equation are (1,4)

Step-by-step explanation:

Given equation is:

$y = x^2 - 5x + 4$

We have to put y=0 in the equation to find zeroes of the equation

$x^2-5x+4 = 0\\x^2 - 4x- x +4 = 0\\x(x-4)-1(x-4) = 0\\(x-4)(x-1) = 0\\x - 4 =0 => x = 4\\x-1 = 0 => x = 1$

Hence,

The zeroes of the equation are (1,4)

Answer: 1050

Step-by-step explanation:

Number of combinations of selecting r things out of n = $^nC_r=\dfrac{n!}{r!(n-r)!}$

such that $^nC_1=n$

Given: A restaurant menu has 5 kinds of soups, 7kinds of main courses, 6 kinds of desserts, and 5 kinds of drinks.

If a customer randomly selects one item from each of these four categories, then by fundamental counting principle , the number of different outcomes are possible = $^5C_1\times \ ^7C_1\times\ ^6C_1\times\ ^5C_1 =5\times7\times6\times5=1050$

hence, total number of outcomes = 1050
