For this case we have that by power properties it is fulfilled:
Now, we can rewrite the expression as:
We also have by definition of properties of powers that:
So:
Answer:
Option D
In this question, we're trying to find the probability of the songs that are not country songs.
We know that you have a total of 150 songs.
There is a 20% probability of randomly choosing a country song, so let's calculate how many country songs are there.
150 · 0.20 = 30
There are 30 country songs in your iPod.
Now, to see how many songs you have that are not country songs, subtract 30 from 150
150 - 30 = 120
This means that you have 120 songs that are not country songs
Answer:
120 songs
Answer:
30Songs are not country songs
Step-by-step explanation:
X/150=20/100
100X=3000
100X/100=3000/100
X=30
d-5
because it is 5 fewer we are subtracting the number five from the variable representing days.
