Answer:
( 3x + 5 ) ( x - 4 )
Step-by-step explanation:
1.) Factors of 20 = (1,20) (2,10) and (4,5)
2.) ( 3x + 5 ) ( x - 4 )
3.) 3x - 12x + 5x - 20 = 0
4.) 3x^2 + 7x - 20 = 0
Solution: The formula for mean is:

Where:
is the sum of given observations
is the number of observations


rounded to two decimal places
To find the median, we need to first arrange the data in ascending order but we are already given the data in ascending order.
Therefore, the median is:






Therefore, the median = 1.53

It is also given that there are 12 seats in each row.
then;
They will fill = 
Therefore, the best estimate the rows will hamsters fill is 40 rows.
