There are 479,001,600 different combinations of songs that can be played without repeating a song

An MP3 player with a playlist of 12 songs can be played in 479,001,600 different orders.

An MP3 player with a playlist of 12 songs can play each song in random order without repetition.

To calculate the number of different orders the songs can be played, we can use the concept of permutations.

In this case, we have 12 songs and want to find the number of different ways they can be arranged.

The formula for permutations is n! / (n - r)!, where n is the total number of items and r is the number of items being arranged.

In this case, n is 12 and r is also 12 (since we want to arrange all the songs).

So the formula becomes 12! / (12 - 12)!. Since 12 - 12 is 0, the denominator becomes 0!.

The value of 0! is defined as 1, so we can simplify the formula to just 12!.

Using a calculator or factorial table, we can calculate that 12! (12 factorial) is equal to 479,001,600.

Therefore, there are 479,001,600 different orders in which the songs can be played on the MP3 player.

The mean is the sum of the elements, divided by the number of the elements:

[tex]\text{mean} = \dfrac{21+32+16+27+22+19+10}{7} = 21[/tex]

The median is the element in the middle of the dataset, once you sort it:

[tex] 10,\ 16,\ 19,\ 21,\ 22,\ 27,\ 32[/tex]

So, the middle element is 21

Finally, the mode is the element that appears more often in the dataset. Since every number appears only once in the dataset, there is no mode.

Answer:

Mean: 10 + 16 + 19 + 21 + 22 + 27 + 32 = 147/7 = 21

Median: 21

Mode: there are no mode in the following data set.

Solution here,

let the both planes covers same distance x while over taking.

For the small plane, let time be t.

speed= 240 mph

now,

distance covered by it,

x=240t--------(1)

For jet plane,let the time be t'.

speed=36mph

since it is flewed after 30 mins, it can be written as,

t'=t-30 min=t-0.5 hr

now distance covered by it,

c=360t'=360(t-0.5)=360t-180----------(2)

equating (1) and (2)

240t=360t-180

or, -120t=-180

or, t=1.5 hr

therefore two planes wiil meet after 1.5 hrs.

putting the value of t in (1)

x=240×1.5=360 m

therefore they travel through 360 m from the airport whlie over taking.

2.

For the first car,

speed=50 Kmph

let it covers x distance at time t

so,diatance x=50t--------(1)

For the second car,

speed=45 Kmph

according to the question, in time t, it will covers the distance (x-20)Km

so, distance(x-20)=45t

or, x=45t+20---------(2)

equating (1) and (2),

50t=45t+20

or, 5t=20

or, t=4 hrs.

therefore cars will be apart of 20 km after 4 hrs.

The jet will overtake the small plane in 1 hour, and they will be 360 miles from the airport. Two cars traveling at 50 kmph and 45 kmph will be 20 km apart after 4 hours.

To solve for the time it takes for the jet to overtake the small plane, we can use the relative speed between the two planes.

First, we calculate the distance the small plane has traveled in the 30 minutes (0.5 hours) head start:

Next, we set up the equation to find the time (t) it takes for the jet to catch up:

Solving for t:

The jet will catch up to the small plane in 1 hour.

To find the distance from the airport when they meet:

For the two cars traveling at different speeds, let's use algebra to determine when they will be 20km apart:

The two cars will be 20 km apart after 4 hours.

Answer:

Step-by-step explanation:

The answers for the given questions are:

(a) Order of popularity: Goron, Zora, Hylian,Gerudo, Other.

(b) Number of people voting for Goron: 89

(c) The estimate was not accurate.

(a) The popularity of the choices from greatest to least is:

1. Goron

2. Zora

3. Hylian

4. Gerudo

5. Other

(b) To find out how many people would have voted for Goron if 280 people voted in total, we first need to determine the proportion of votes Goron received in the primary election.

Total votes cast in the primary election = Sum of votes for all choices

= Goron + Zora + Hylian + Gerudo + Other

= 100 + 75 + 60 + 40 + 40

= 315 votes

Proportion of votes for Goron = (Votes for Goron / Total votes cast) * 100%

= (100 / 315) * 100%

≈ 31.75%

Now, to find out how many people would have voted for Goron out of the estimated 280 people:

Number of people voting for Goron = (Proportion of votes for Goron / 100%) * Estimated total voters

= (31.75 / 100) * 280

≈ 89 people

(c) The estimate of total voters from Part (b) was not accurate. The estimate was based on the assumption that all choices would receive votes in the same proportion as they did in the primary election. However, in reality, the number of votes for "Other" was higher than expected, indicating that the actual total number of voters might be higher than the estimated 280. Therefore, the estimate was not accurate.

Complete question:

The results of the primary election are shown. (a) Order the popularity of the choices from greatest to least. (b) It was estimated that 280 people were going to vote. If this was true, how many people would have voted for Goron? Show your work. (c) 40 people voted for “Other.” Was the estimate of total voters from Part (b) accurate? Explain.

Answer:

False

Step-by-step explanation:

The equation in slope-intercept form of a line is y=mx+b, where x and y can represent a point on the line by using the coordinates (x,y), m is the slope, and b is the y intercept.

To double check this equation, plug in the coordinates of the point (3,6) to make sure both sides of the equation equal to each other.

6 = -5(3) + 7

6 = -15 + 7

6 = -8

[tex]6 \neq -8[/tex]

Because the equation is invalid, the line does not pass through these points.

The statement is false because the equation y = -5x + 7 does not satisfy the point (3,6).

To determine if the equation y = -5x + 7 is the equation of a line that passes through the point (3,6) and has a slope of -5, we can plug the coordinates of the point into the equation to see if it satisfies the equation.

Substituting x = 3 and y = 6 into the equation gives us:
6 = -5(3) + 7,
which simplifies to:
6 = -15 + 7,
6 = -8, which is not true.

Therefore, the point (3,6) does not lie on the line with the equation y = -5x + 7. The equation y = -5x + 7 does, however, represent a line with a slope of -5, but since it does not pass through the point (3,6), the initial statement is false.

EXPLANATION

The line from the center of the circle to the upper chord meets it at right angles, this means that, this line bisects the upper chord.

Hence the length of the upper chord is 2(11)=22 units.

Since the distance from the upper chord to the center is 12 units and the distance from the lower chord to the center is also 12 units, the two chords must be equal.

Answer:

[tex]y=\dfrac{3}{2}\cdot 2^x[/tex]

Step-by-step explanation:

The general equation of the exponential function is

[tex]y=a\cdot b^x[/tex]

If the graph of the exponential function passes through the points (-2, 0.375) and (7, 192), then their coordinates satisfy the equation:

[tex]0.375=a\cdot b^{-2}\\ \\192=a\cdot b^7[/tex]

Divide the second equation by the first:

[tex]\dfrac{192}{0.375}=\dfrac{a\cdot b^7}{a\cdot b^{-2}}=\dfrac{b^7}{b^{-2}}\\ \\512=b^9\\ \\b=\sqrt[9]{512}=2[/tex]

Substitute it into the second equation:

[tex]192=a\cdot 2^7\\ \\192=a\cdot 128\\ \\a=\dfrac{192}{128}=\dfrac{96}{64}=\dfrac{48}{32}=\dfrac{6}{4}=\dfrac{3}{2}[/tex]

So, the equation of the exponential function is

[tex]y=\dfrac{3}{2}\cdot 2^x[/tex]

so we have two parallel lines, notice, the 115° are corresponding angles and thus equal,  the 65° and 55° angles are linear angles to 115° and 125° respectively.

that leaves us with a triangle with 65° and 55°, and since all interior angles in a triangle sum up to 180°, then the last angle must be 60°, which has a twin vertical angle across the junction.

since a full revolution or a full circle go-around is 360°, the other two twin vertical angles next to the green 60° angles must be 360° - 60° - 60° = 240°, and since they're twins, each takes half of 240°.

[tex]8\ units < x < 28\ units[/tex]

Step-by-step explanation:

we know that

The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x---->the possible lengths for the third side

Applying the triangle inequality theorem

Analyze two cases

 case 1)

[tex]10+18 > x[/tex]

[tex]28 > x[/tex]

Rewrite

[tex]x < 28\ units[/tex]

case 2)

[tex]10+x > 18[/tex]

[tex]x > 18-10[/tex]

[tex]x > 8\ units[/tex]

therefore

The inequalities that describe the values that possible lengths for the third side are

[tex]x > 8\ units[/tex]

[tex]x < 28\ units[/tex]

The compound inequality is

[tex]8\ units < x < 28\ units[/tex]

The possible lengths for the third side of a triangle with sides of lengths 10 and 18 can be found using the triangle inequality theorem. These lengths are denoted by 'x', and must satisfy the inequalities: 8 < x < 28. This rule applies to all triangles, not just right-angled ones.

The question relates to the rules governing triangle side lengths. Specifically, the question draws from the triangle inequality theorem, which states that the length of any side of a triangle must be less than the sum of the lengths of the other two sides, but more than the absolute difference of those lengths. Hence, for a triangle with sides of lengths 10 and 18, the possible lengths of the third side (denoted 'x') must satisfy the inequalities: 8 < x < 28.

These inequalities come from the principle that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side: 10 + 18 > x and 18 - 10 < x. Otherwise, the lengths would not meet to form a closed three-sided figure.

It's also worth noting that these rules hold true for any triangle, not just right triangles. Hence, this problem doesn't involve the Pythagorean theorem, which specifically relates the sides of a right-angled triangle.

Answer:

C  1055 04 cm

Step-by-step explanation:

We don't need to see the figure, since we know for sure the cone fits into the cylinder (smaller diameter and height).

So, we first need to calculate the volume of the cylinder, which is given by the formula:

VT = π * r² * h

VT = 3.14 * 5² * 16 = 3.14 * 400 = 1,256 cubic cm

Then we calculate the volume of the cone, which is given by:

VC = (π * r² * h)/3

VC = (3.14 * 4² * 12)/3 = (3.14 * 192)/3 = 200.96 cu cm

Then we calculate the void space left inside the cylinder by subtracting the volume of the cone from the volume of the cylinder:
