Answer:

Different playlists possible = 18287141644800

Step-by-step explanation:

Given - DJ Titus is making a playlist for a radio show; he is trying to

            decide what 10 songs to play and in what order they should be

            played.

            Step 1 of 2 : If he has his choices narrowed down to 7 blues,

                                 7 disco, 5 pop, and 7 reggae songs.

To find - He wants to play no more than 4 reggae songs.

              How many different playlists are possible ?

Proof -

Given that he wants to play no more that 4 reggae songs.

So the possibility of choice of reggae song is 0, 1, 2, 3, 4

Now,

Case I -

If 0 reggae song is selected

⇒All 10 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₁₀ ₓ ⁷C₀ = 92,378

Case II -

If 1 reggae song is selected

⇒All 9 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₉ ₓ ⁷C₁ = 646,646

Case III -

If 2 reggae song is selected

⇒All 8 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₈ ₓ ⁷C₂ = 1,587,222

Case IV -

If 3 reggae song is selected

⇒All 7 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₇ ₓ ⁷C₃ = 1,763,580

Case V -

If 4 reggae song is selected

⇒All 6 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₆ ₓ ⁷C₄ = 949,620

So,

Total possible ways = 92,378+ 646,646+ 1,587,222+ 1,763,580+ 949,620

                               = 5,039,446

⇒Total possible ways = 5,039,446

Now,

Also the 10 songs selected can arranged themselves in 10! ways. ( because order of song played does not matter )

∴ we get

Different playlists possible = 10! × 5,039,446

                                          = 18287141644800

⇒Different playlists possible = 18287141644800

700.8+221.6+3877.6+5877.6+74.392+109.6368=$6984.0288

6984.0288÷36=$194.0008

the monthly payment for Michelle's consolidated credit card balance would be approximately $201.59.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,  the total balance of all four credit cards:

Total balance = $4380 + $1385

Total balance = $5765

Hence, Determine the interest rate for the consolidated credit card: Interest rate = 16%

And, the term of the loan:

Term = 36 months

Hence, Use a loan calculator to calculate the monthly payment, using the total balance, interest rate, and term:

Monthly payment = $201.59

So, the monthly payment for Michelle's consolidated credit card balance would be approximately $201.59.

Answer:

[tex]T_7 = 136.6875[/tex]

Step-by-step explanation:

Given

12, 18, 27, ..

Required

Determine the 7th term

The above sequence shows a geometric sequence and the nth term is calculated by:

[tex]T_n = a * r^{n-1[/tex]

r is calculated by:

[tex]r = \frac{T_2}{T_1}[/tex]

[tex]r = \frac{18}{12}[/tex]

[tex]r = 1.5[/tex]

[tex]a = 12[/tex] --- First term

[tex]n = 7[/tex]

So:

[tex]T_n = a * r^{n-1}[/tex]

[tex]T_7 = 12 * 1.5^{7-1[/tex]

[tex]T_7 = 12 * 1.5^6[/tex]

[tex]T_7 = 136.6875[/tex]

Answer:

Mark

Step-by-step explanation:

because when x = 0; y = 1

x=1; y=4

and those points are on the solid line graph.

The thought of Mark is correct.

Exponential functions are functions where the independent variable, x is in the exponent.

Given a graph.

It has a solid line and a dotted line.

The given equation is, y = 4ˣ.

In order to find which graph shows the equation, find the points that the graph of the equation will pass through.

When x = 0, y = 4⁰ = 1

Solid graph passes through (0, 1).

Hence Mark is correct.

Step-by-step explanation:

-9.5x-1.5>-30

Hello There!

So once again we want to isolate the variable using inverse operations

To get rid of the 1.5 we add 1.5 to each side

-1.5+1.5 cancels out

-30+1.5=-28.5

now we have

-9.5x>-28.5

to get rid of the -9.5 we divide each side by -9.5

-9.5x/-9.5=x

-28.5/-9.5=3

Remember we are dividing by a negative number so we have to flip the inequality sign

We're left with

Answer:

x = -232

Step-by-step explanation:

Ronu's present age is "x “years and her sister Shaani's present age is twice  of Ronu's age.

(a) Ronu's present age = x years

(b) Ronu's age after 2 years = (x+2) years

(c) Shaani's present age = 2x years

(d) Shaani's age after 2 years = (2x+2) years

Let x should be added to 100 to get -132.

x+100 = -132

x = -100-132

x = -232

Hence, -232 must be added to 100 to get -132.

Step-by-step explanation:

Insurance costs are influenced by any factor that can reasonably be tied to the cost of claims made against an insurance policy. These costs are carefully analyzed by insurance companies to determine correlations that may be influential.

__

In general, women have different driving habits than men, so gender has an influence on insurance costs.

Some areas of a city have different statistics related to vandalized or stolen vehicles, so may influence insurance costs. Certain areas may have different accident statistics, or may experience different kinds of accidents, so repair costs may differ by where you live or where you drive.

Some cars are more expensive to repair than others. Any car with custom features (stereo, upholstery, paint) will likely cost more to repair (and may be subject to more vandalism).

So, all of the above influence insurance costs.

  b.  -75°

Step-by-step explanation:

Point A moves from (-4, -3) to (-4, 3). We can find the angle of rotation several ways. One is to consider the tangent of the angle relative to the x-axis.

Point A is on a line that makes an angle to the x-axis of ...

  ∠A = arctan(-3/-4) = 36.9°

Point A' is on a line that makes an angle to the x-axis of ...

  ∠A' = arctan(3/-4) = -36.9°

Then the change in angle is ...

  ∠A' -∠A = -36.9° -36.9° = -73.8°
