The total distance Tracy traveled was 15,000 feet assuming each unit represents 1,000 feet.
<h3>How to calculate the total distance?</h3>The total distance is the sum of all the distance between stops.
Partial distances:
- Home to stop 1: 2,000 feet
- Stop 1 to 2: 4,000 feet
- Stop 2 to 3: 5,000 feet
- Stop 3 to 4: 4,000 feet
- Total distance: 15,000 feet
However, the real distance would be 10.63 units based on the locations in the grid.
- d=√(0−8)^2+(7−0)^2
- d=√8^2+7^2
- d=√64+49
- d=√113 =10.63 units

Answer:
The margin of error of his experiment is of 0.1074.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
30 M & M's from a bag, and 3 of them are green.
This means that
Standard 95% confidence level
So , z is the value of Z that has a p-value of
, so
.
Margin of error:
The margin of error of his experiment is of 0.1074.
