Answer:
The average useage of the 30 individuals sampled is 85 gallons per day
Step-by-step explanation:
A confidence interval has two bounds, the lower bound and the upper bound.
A confidence interval is symmetric, which means that the sample mean is the halfway point between these two bounds, that is, the sum of them divided by two.
In this problem, we have that:
Lower bound: 82
Upper bound: 88
Determine the average useage of the 30 individuals sampled
(82 + 88)/2 = 85
The average useage of the 30 individuals sampled is 85 gallons per day
No, 0.76 is greater than 0.67.
Convert them into fractions
i)-2 3/8 = -19/8
ii)0.75 = 75/100 = 3/4
iv) 1 3/4 = 7/4
Now convert all of them in the form of p/q where q = 8
Therefore
ii)6/8
iv) 14/8
Answer:
Cam is at 6m below the surface of the water.
Step-by-step explanation:
Ignore all info except:
Ben is 8 meters below the surface of the water.
Cam is 2 meters above Ben
So now answer this;
What is Cam's position relative to the surface of the water?
This is too simple. Cam is 2 m above Ben which means two meter closer to the surface as Ben.
Ben was 8 m below the surface. By this Cam is 2 m closer to the surface, which is 8 - 2 = 6 m.
Cam is at 6m below the surface of the water.
