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

Which logarithmic equation is equivalent to the exponential equation below?
Nataly_w [17]
With any equation you are allowed to take the logarithm of both sides so
5^c=125 now take the logarithm base 5 to both sides giving.
log5(5^c)=log5(125), using the rule log(a^b)=a*log(b) you get
c log5(5)=log5(125), since log5(5)=1
c=log5(125)
