Answer:
1/4
Step-by-step explanation:
The fraction of the juice Alisa drank was
3/8 liter
--------------------
3/2 liters
and this fraction can be simplified by inverting the divisor (3/2 liters) and multiplying instead:
3 2
------ * ----- = 2/8 or 1/4
8 3
Alisa drank 1/4 of the juice that was originally in the bottle.
Answer: mean=87, median=87.5 and range=18
Step-by-step explanation:
Mean:
First add all the numbers
78+95+77+92+87+79+94+86+88+94 = 870
Then you divide the answer by counting the numbers
870÷10
=87
Median:
First arrange the numbers in ascending order (from smallest to largest)
77, 78, 79, 86, 87, 88, 92, 94, 94, 95
pick the two middle numbers which is 87 and 88
then you do 
= 175÷2
= 87.5
range = Largest number - smallest number
= 95-77
= 18
Y + 0.4 = 2 .....subtract 0.4 from both sides
y = 2 - 0.4
y = 1.6 <==
