Thereare 30 students in mr.holland's music class.if 30% of the students play in the school band,how many students in the class p
stiv31 [10]
9 students in the class play in the school band. 

30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3

In math, the word of  means multiplication, so: 0.3 x 30 
Which equal 9. 

You can also turn the percentage into a fraction, it's really up to preference. 

30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9

The following frequency table summarizes last week's bed sales at Cloud Nine Furniture.
Masteriza [31]

Answer:

Option A. 0.20

Step-by-step explanation:

Observations from the given frequency table are :

Total number of beds sold at Cloud Nine Furniture = 3 + 6 + 4 + 2

                                                                                     = 15

Number of twin beds sold = 3

Then, probability that the next bed sold will be a twin bed,

P=\frac{\text{favorable outcome}}{\text{total number of possible outcomes}}

  =\frac{3}{15}

  = 0.20

Therefore, the probability that the next bed sold is a twin bed will be 0.20 or 20%.

Option A. is the correct answer.
