Answer:
outcome for rock = 21/60 = 7/20
outcome for rap = 3/20
outcome for dance = 3/10 or 6/20
outcome for country 1/5, 2/10 or 4/20
Step-by-step explanation:
possible outcomes = 21+9+18+12 = 60
outcome for rock = 21/60 = 7/20
outcome for rap = 3/20
outcome for dance = 3/10 or 6/20
outcome for country 1/5, 2/10 or 4/20
The probability of playing a rap song is 3/20.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
0.71 An MP3 player has 60 songs.
The sample space is the number of songs stored in MP3 player.
⇒ [tex]n(s)=60[/tex]
Number of rock songs, [tex]n(rock)=21[/tex]
Number of rap songs, [tex]n(rap)=9[/tex]
Number of dance songs, [tex]n(dance)=18[/tex]
Number of country songs, [tex]n(country)=12[/tex]
Formula for the probability of an event is [tex]P(e)=\frac{n(e)}{n(s)}[/tex]
Probability of playing a rock song, [tex]P(rock)=\frac{21}{60}[/tex]
⇒ [tex]\frac{7}{20}[/tex]
Probability of playing a rap song, [tex]P(rap)=\frac{9}{60}[/tex]
⇒ [tex]\frac{3}{20}[/tex]
Probability of playing a dance song, [tex]P(dance)=\frac{18}{60}[/tex]
⇒ [tex]\frac{9}{20}[/tex]
Probability of playing a country song, [tex]P(country)=\frac{12}{60}[/tex]
⇒ [tex]\frac{1}{5}[/tex]
Hence we can conclude that the probability of playing a rap song is 3/20.

Find the maximum and minimum values of the function. y=1/2sin2x
Answer:
(-1/2,1/2)
Step-by-step explanation:
Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.

The radius is 6 and the height is 15 what is the volume in terms of pi the shape is a cone
Answer:
565.49 or if rounded to the nearest tenth, 565.5
Explanation:
The formula for finding the volume of a cone is V=1/3Bh
B = pi times the radius squared
h = height
Substitute 6 for r and 15 for h.
V= 1/3·[tex]\pi[/tex]·([tex]6^{2}[/tex])·15
Multiply.
V= 565.49 or 565.5 rounded to the nearest tenth.

La montaña más alta del mundo es Everest cuya altura es de 8.848m y la altura de la segunda montaña más alta es de 2hm 3dam y 7m menos ¿Cuantos metros de altura tiene la segunda montaña más alta del mundo
Answer:
La segunda montaña más alta del mundo tiene 8611 metros.
Step-by-step explanation:
La montaña más alta del mundo es Everest cuya altura es de 8.848m.
La altura de la segunda montaña más alta es de 2hm 3dam y 7m menos. Para calcular la altura que tiene la segunda montaña más alta del mundo, debes realizar primero un cambio de unidades sabiendo que
1 hm= 100 m1 dam= 10 mEntonces podes aplicar las siguientes reglas de tres simple:
Si 1 hm equivale a 100 m, 2 hm equivale a ¿Cuántos metros?
[tex]metros=\frac{2 hm*100 m}{1 hm}[/tex]
metros= 200
Si 1 dam equivale a 10 m, 3 dam equivale a ¿Cuántos metros?
[tex]metros=\frac{3 dam*10 m}{1 dam}[/tex]
metros= 30
Entonces, la altura de la segunda montaña más alta es de 200 m+30 m+ 7 m menos que el Everest. Esto es, 237 metros menos que la montaña más alta del mundo. Entonces:
8848 metros - 237 metros= 8611 metros
La segunda montaña más alta del mundo tiene 8611 metros.

Actually Welcome to the concept of Isosceles triangles.
They have two sides equal to each other, so we get as,
==> 3x + 3 = 2x + 8
==> 3x - 2x = 8-3
==> x = 5
hence the length of AC = 5 units.
Answer:
AC = 5
Step-by-step explanation:
here's your solution
=> This is a isosceles triangle
=> both sides are equal.
=> AB = CB
=> 3x + 3 = 2x + 8
=> 3x - 2x = 8 - 3
=> x = 5
so, AC = 5

Mrs perez drove at constant rate of speed she drove a total of 33.75 miles in 3/4 of hours what was the speed in miles per hour that mrs Perez traveled if this situation is represented by the equation d=rt
Answer:
Speed in miles per hour = 45 miles per hour
Step-by-step explanation:
Given:
Distance cover by Mrs Perez = 33.75 miles
Time taken by Mrs Perez = 3/4 hours = 0.75 hour
Find:
Speed in miles per hour
Computation:
Speed = Distance cover / Time taken
Speed in miles per hour = Distance cover by Mrs Perez / Time taken by Mrs Perez
Speed in miles per hour = 33.75 / 0.75
Speed in miles per hour = 45 miles per hour
