(1,4) you go right 1 time, and than go up 4.
Answer:
You must drink 52 7/12 ounces or 52.58 ounces to reach the goal.
Step-by-step explanation:
Total amount of the water already drank is found by adding the fractions
So
3 1/10 ounces + 2 1/15 ounces + 6 5/20
Converting into improper fractions
31/10 + 31/15+ 125/20
Now finding the lcm of 10,15,20
so Factors of 10 = 2 x 5
Factors of 15 = 5 x 3
Factors of 20 = 2 x2 x5
LCM= 5x2x2x3= 60
31*6/60 + 31*4/60 + 125*3/60
= 186+124+375/60
= 685/60 = 11.42 ounces
The amount of water already drank is 11.42 ounces
The amount remaining is found by subtracting the amount drank from the total amount
so
64 ounces - 11.42= 52.58
It can be solved in fractions as
64- 11 5/12
Again taking making improper fraction and taking lcm
64- 137/12
= 768-137/12 = 631/12= 52 7/12 ounces
This question is incomplete.
The complete question says;
The two-way table shows the number of hours students studied and whether they studied independently or with a study group.
What is the relative frequency of students that studied independently for more than 2 hours to the total number of students that studied independently?
a) 0.4 c) 0.25
b) 0.33 d) 0.11
Table is attached as image
Answer: C (0.25)
The number of students that studied for more than 2 hours as given in the table are 4.
The total number of people that studied independently include those that studied less than 2 hours and those that studied for more than 2 hours.
Those that studied less than 2 hours independently are 12.
Those that studied more than 2 hours independently are 4.
Hence the total number of people that studied independently is 16.
Therefore the relative frequency of students that studied independently for more than 2 hours to the total number of students that studied independently would be = 4/16 = 1/4 = 0.25.
