Chen plans on listening to 360 songs, and if she has 444 <span>classical songs, 333 rock songs, and 222 rap songs, the ratio of the songs she have would be 4:3:2. We can add 4,3, and 2 to get 9. 360/9=40.Now, we do 40*4 to get 160. 
Chen will be listening to 160 songs.</span>

Answer:  The best prediction for classical songs is 160.

Step-by-step explanation:  Given that Chen's Jumble has 444 classical songs, 333 rock songs, and 222 rap songs on it. Chen is going to listen to 360 songs.

We are to find the best prediction for the number of classical songs that Chen will listen.

The ratio of the classical songs, rock songs and rap songs on Chen's Jumble is given by

444:333:222\\\\=4:3:2.

Therefore, the number of classical songs that Chen will listen is

N_c=\dfrac{4}{4+3+2}\times 360=\dfrac{4}{9}\times 360=4\times 40=160.

Thus, the best prediction for classical songs is 160.

Three students have already enrolled for a creative writing class. The teacher will cancel the class if there are fewer than 10
JulijaS [17]

Answer:

7, 10 and 15

Step-by-step explanation:

Given

S_1= 3  --- Students already enrolled

Total = 10\ (less)

Required

Determine the additional number of students needed for the teacher not to cancel the class

First, we need to calculate the number of students for the teacher to cancel the class.

Represent this with x.

So, we have:

S_1 + x < Total

Make x the subject

x < Total - S_1

Substitute values for Total and S1

x < 10 - 3

x < 7

This means that if less than 7 additional students come to the class, the teacher will cancel the class.

So, for the teacher not to cancel the class, the students must be 7 or greater (i.e. 7, 8, 9, 10....)
