Answer:
75 green marbles
Step-by-step explanation:
From the information given in the question, we can create a ratio representing all the marbles in the bag.
9 red:15 green:6 blue
We need to find the total number of times the student drew a marble by finding the sum
9+15+6= 30
The sample size is 30
150 is 5x the amount of 30, that means we need to multiply the given information by 5 to predict the number of green marbles
9x5=45
15x5=75
6x5=30
Now we have 45 red: 75 green: 30 blue
Based on the given information, we can predict that the bag contains 75 green marbles

Answer:
0.7
Step-by-step explanation:
67/10 is the same as 6.7 when you subtract the 0.7 you will remain with 6
90 mins + 50 mins = 140 mins
60 mins ==1 hr 2*60 = 120 mins
140 mins -120 mins= 20 mins
2 hrs ans 20 mins is the answer
