Answer:
Hence, the probability of selection of one new rock song is .
Step-by-step explanation:
As given in the question, Doug bought 9 new country songs and 5 new rock songs.
and we have to find the probability that it will be a rock song.
Now,
Doug bought 9 new country songs
Doug bought 5 new rock songs
Therefore, Total number of songs bought by Doug = 9 new country songs + 5 new rock songs
∴ Total number of songs bought by Doug = 5+9 = 14.
∵
Let, the event A is defined as the selection of one Rock Song
∴
Hence, the probability of selection of one new rock song is .

Answer:
24 times
Step-by-step explanation:
cone is used to fill cylinder
conevolume times x=cylindervolume
so
x=cylinderv/conev
cylinderv=hpir^2
conevolume=1/3hpir^2
cylinder:
v=hpir^2
r=10
h=20
v=20*pi*10^2=2000π
cone=1/3hπr²
r=5
h=10
v=1/3(10)π5²=250π/3
volume of cylinder ÷ volume of cone
= 2000π ÷ (250π÷3)
= 6000π ÷ 250π
= 600÷25
= 24

Answer:
6 / (5/4) = 4.8
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
6 x 4 /5 = 24 /5
Thus, the answer to 6 divided by 5/4 in fraction form is:
24/5
To make the answer to 6 divided by 5/4 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
24 / 5 = 4.8
The answer is rounded to the nearest two decimal points if necessary.
24/5 is an improper fraction and should be written as 4 4/5.
