Calculate the number of ways to form a set of three distinct items such that no two of the selected items are in the same row or
Eddi Din [679]

Answer:

1200

Explanation:

Order does not matter, if we said xyz order, it would still not make a difference if it was zyx or yzx hence we use the combination formula:

nCr = n! / r! * (n - r)!

where n= total number of items

r= number of items chosen at a time

Combinations are used when the order of events do not matter in calculating the outcome.

We calculate using the formula:

(30×20×12)÷3!=1200

There are therefore 1200 ways for the three distinct items to not be in same row or column

Please help me I’m struggling :’(
Vesna [10]

Answer:

B. x = \sqrt{40}

Step-by-step explanation:

Using Pythagorean theorem, find the value of x.

Pythagorean theorem is given as c^2 = a^2 + b^2

Where,

c is the longest side of a right angled ∆ = the hypotenuse = x

a and b are legs of the right angled ∆ = 2 and 6

Plug in the values into the equation and solve for x

x^2 = 2^2 + 6^2

x^2 = 4 + 36

x^2 = 40

x = \sqrt{40}

enyata [817]
<h2>Translating Words into Problems</h2>

We can translate a word equation into a mathematical equation by translating key words into operations.

  • <em>difference</em> = subtract
  • <em>is</em> = equals

<h2>Addinng Fractions</h2>

Whenever we need to add one fraction to another, we must find a common denominator, change both the fractions for their denominators to be the same, and then add the numerators. Finally, we reduce the fraction.

<h2>Solving the Question</h2>

We're given:

  • The difference of n and \dfrac{1}{6} is \dfrac{1}{2}.

Translate the given information into an equation:

⇒ n-\dfrac{1}{6}=\dfrac{1}{2}

Solve for <em>n</em>:

⇒ n-\dfrac{1}{6}=\dfrac{1}{2}\\\\n=\dfrac{1}{2}+\dfrac{1}{6}\\\\n=\dfrac{3}{6}+\dfrac{1}{6}\\\\n=\dfrac{4}{6}\\\\n=\dfrac{2}{3}

<h2>Answer</h2>

n=\dfrac{2}{3}
