Answer:

97% confidence interval for the survey is between a lower limit of 0.45 and an upper limit of 0.67

Step-by-step explanation:

Confidence Interval is given by the mean + or - error margin

The lower limit of the confidence interval is found by subtracting the error margin from the mean.

The upper limit is obtained by adding the error margin to the mean.

The interpretation is that the mean is between 0.45 and 0.67

Taxi ride is 1.85 per mile with an initial 2.75 charge, what is the cost in dollars for a 20 mile taxi ride
kati45 [8]

Answer:$39.75

First, we have to find out how much would it be for a 20 mile taxi ride. To do this, we have to multiply. 20 x $1.85= $37.00.

Lastly, you have to find out how much the cost will be with the initial charge. To do this, we have to add. $37.00+$2.75=$39.75.

Hope this answered your question!
