Alright, lets get started.
experiment yields the following data: minute 1: 65 breaths; minute 2: 73 breaths; minute 5: 62 breaths
Total number of breaths = 
Total minutes observes = 3 minutes
So, average breaths per minute will be = 
So, the average number of breaths that a fish takes per minute is 66.67. : Answer
Hope it will help :)
Answer:
2) is not proportional, 3) is not proportional, 5) is proportional, 6) is not proportional.
Step-by-step explanation:
Number 2 is not proportional since it doesn't go through the origin on the graph and the line is not a straight line.
Number 3 does not go through the origin, so number 3 is also not proportional.
Number 5 is proportional since when you divide y by x, it is always 7.
Number 6 is not proportional because when you divide y by x or x by y there are not the same answers.
Answer:
that is the solution to the question
2√72 / √8 ± √2
If the denominator is √8 + √2,
2√72 / √8 + √2
= 2√(2*2*2*3*3) / √(2*2*2) + √2
= 2*2*3√2 / 2√2 + √2
= 12√2 / 3√2
= 4
