What is the number of different ways to order a 5-song playlist chosen from a selection of 12 songs?

1 answer:

3 0

As far as I can tell is just a Permutation.

$\bf _nP_r=\cfrac{n!}{(n-r)!}\qquad \qquad \qquad _{12}P_5=\cfrac{12!}{(12-5)!}$

Rewrite equation to solve for m 4n-6m=-2

hram777 [196]

Answer:

Step-by-step explanation:

4n - 6m = - 2 Subtract 4n from both sides.

4n-4n - 6m = -2-4n

-6m = - 2 - 4n Divide by - 6

-6m/-6= -2/-6 -4n/-6 Do the division

m = 1/3 + 2n/3

The signs change because each term has 2 minus signs. 2 minus signs make a plus. Or both minus signs cancel.

Does 4/7 lies between the numbers -3/5 and 3/4

Nesterboy [21]

one way to do this is to convert each fraction to same denominator ( the LCD)

Well we can eliminate -3/5 because its negative so 4/7 is definitely > -3/5.

4/7 = 16/28 and 3/4 = 21/28

so 4/7 < 3/4

Therfore 4/7 does lie between the 2 fractions

What is the diameter of a sphere with volume of 7483

elena-14-01-66 [18.8K]

Answer:

The diameter of the sphere with the given volume is 24.268 units

Step-by-step explanation:

Volume of a sphere is given by the equation:

$V=4/3\pi r^3$

Plug in your volume and solve for r

$7483=4/3\pi r^3$

$7483(3/4)=\pi r^3$

$5612.25=\pi r^3$

$5612.25/\pi =r^3$

$1786.43=r^3$

$\sqrt[3]{1786.43}=r$

$r = 12.134$ units

$d = 2r$

$d = 2(12.134)$

$d = 24.268$ units
