Step-by-step explanation:
15%=3

5(20)=100
1(20)=20
So, there are 20 students in the class.
Find range ,median mode and mean of the following numbers -19,-11,-19,-18,-13,-19,-18,-11.0, 11,12

Range= 31 because 12- -19 = 31 you subtract the lowest with the highest.
Mean= 8.3
Mode = -19 because you mostly see -19 there’s 3 -19 . :)))
Answer:
528 dollars
Step-by-step explanation:
The starting price is $600. And it goes down by 20% then comes back up 10% so steps are:
First we got 20% off so I did 100 - 20 and got 80%
1: 80% * 600 = 80/100 * 600 = 480
Then we get an increase of 10% so I multiplied 110% with 480 which was our new price
2. 110/100 * 480 = 11 * 48(simplifying)
= 528
