How can you tell whether a counting problem is a permutation or combination problem? Give examples to support your answer

dolphi86 [110]

Answer:

Step-by-step explanation:

Permutation is the ways in which a fixed group or members that can be arranged or ordered and combinations are used when a smaller group has to be chosen from a larger group.

Examples:

<u>Permutation: </u>How many unique combinations of the word MAHNOOR can be formed when the letters will be scrambled

2. In what order or arrangements five people can be seated in the front row?

The number of people are fixed, we have to find the order.

<u>Combination:</u> Choosing two cards from a deck of 52 cards. We are choosing a small group from a larger group of all cards.

2. Choosing 4 students from a class to take part in the competition.

The selection can be made in multiple ways ..

The diagram shows a straight line ABCD.

Nady [450]

Answer:

B (0, 285 ) , C (380, 0 )

Step-by-step explanation:

the first step is to obtain the equation of the line in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = A(- 260, 480 ) and (x₂, y₂ ) = D (620, - 180 )

m = $\frac{-180-480}{620-(-260)}$ = $\frac{-660}{620+260}$ = $\frac{-660}{880}$ = - $\frac{66}{88}$ = - 0.75 , then

y = - 0.75x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equatio

using (620, - 180 ) , then

- 180 = - 465 + c ⇒ c = - 180 + 465 = 285

So y- intercept is B (0, 285 )

y = - 0.75x + 285 ← equation of line

to find the x- intercept , let y = 0 in the equation and solve for x

0 = - 0.75 + 285 ( subtract 285 from both sides )

- 285 = - 0.75x ( divide both sides by - 0.75 )

380 = x

x- intercept is C (380, 0 )

F(x)=(x+1)(x-3)(x-4)

denis23 [38]

Answer:

x=-1, x=3, x=4

Step-by-step explanation:

1. Substitute 0 for f(x)

0=(x+1)(x-3)(x-4)

2. Set each set of parenthesis equal to 0

0=x+1, 0=x-3, 0=x-4

3. Solve for x

x=-1, x=3, x=4
