As given that there are 14 bands have volunteered to perform but there is only enough time for 5 bands to play.

So the total lineups are:

\begin{gathered} 14p5=\frac{14!}{(14-5)!} \\ 14p5=\frac{14!}{9!} \\ 14p5=240240 \end{gathered}

So the total lineups are 240240.

You have tiles numbered 1-9 in a bag. What is the probability of drawing a multiple of 3,putting it aside, and then drawing the
mafiozo [28]

Answer:

1/18

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

Multiples of 3 between 1 - 9 = 3,6,9

Probability of picking a multiple of 9 = total multiples of 9 in the bag / total tiles in the bag

3/9

To transform to the simplest form. divide both the numerator and the denominator by 3

1/3

After picking the multiples of 3, the tiles are not replaced, tiles in the bag would now be 6

Probability of picking 5 = 1/6

1/6 x 1/3 = 1/18

PLEASE HELP ASAP....i’ll mark brainlest
Sidana [21]

Answer:

True

Step-by-step explanation:

Kilo means 1,000 so kilometers means 1,000 meters. If you don't know prefixes it might be kind of confusing because centimeters doesn't mean 100 meters so I'll leave something here.

Kilometers = 1000 meters

1 meter = 10 decimeters

1 decimeter = 10 centimeters

1 centimeter = 10 millimeters

If I have time later I'll attach a visual that could help.

A company sells gadgets for $20/gadget and has a profit function from making and selling x gadgets of P(x) = 15x - 6000.
DENIUS [597]
This is the concept of algebra, at breakeven point there are no profits made. Hence, given the profit function 
P(x)=15x-6000
at breakeven point the number of units sold will be:
P(x)=0
thus:
0=15x-6000
15x=6000
x=400
the number of units sold at breakeven will be 400 units.
 The amount at breakeven wil be:
number of units x price of each unit
=400x20
=$ 8000

The results found are true breakeven point because at these points the company will not be generating any profits because the amount of revenue generated will be equal to the amount of expenses. This means that the difference between revenue and cost will be zero, therefor it satisfies the breakeven point rationale.

Calculate the amount of money​ you'll have at the end of the indicated time​ period, assuming that you earn simple interest.You
patriot [66]
First you need to figure out what 5.4% of 3600 is. So take 3,600 x 0.054. This equals 194.4. You then want to add this to 3,600. This will equal 3,794.4. You then want to do the process again, so the interest this year comes from 3,794.4 x 0.054. This equals about 204.9 (if you can it is 204.8976). Then you want to add that back into 3,794.4 so it will equal about 4,000 (or 3,999.2976) Well now this is a long process, but its the one way I remember how to do it.
