First, find the slope for the line. Choose any 2 points and note their coordinates. I'll take (0,4) and (2,10) as an example. Then you apply your formula, remembering each coordinate comes in the form of .
The slope () is 3.
In this case, the slope represents the price per kilometer.
So, the fare is $3 per kilometer + the base fare, which is the value already present at 0km. According to the graph, when ,
.
Let's assume the following:
Price per Kilometer,
Base Fare,
Amount of Kilometers,
Total Cost
The total fare would be calculated by the following formula:
Using the given values:
In conclusion, the total cost for 6km is $22. Option A.
Answer:
The 95% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample mean difference is
The standard error is SE = 0.03
Given that the confidence interval is 95% then the level of significance is mathematically evaluated as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the margin of error is mathematically represented as
substituting values
The 95% confidence interval is mathematically represented as
substituting values
