The percentage error is 23%
Explanation:
The estimated total cost of the groceries = $50
The actual cost of the groceries = $65
To find the error value, we need to subtract the value of actual cost and total cost of the groceries.
Thus,
error value = actual cost - total cost
error value
Hence, error value = $15
The formula to determine the percent error is given by
Substituting the values in the formula, we get,
Rounding off the value, we have, 23%
Thus, the percentage error is 23%
Answer:
Slope = 7/4
Step-by-step explanation:
You are given coordinate values and a formula that tells you what to do with them. All you need to do is put the values in the formula and do the arithmetic.
<h3>Points</h3>You are given points (2, -3) and (6, 4). The slope formula refers to the two points as (x1, y1) and (x2, y2). It does not matter which is which.
If we use the points in the same order they are given, then we can see that ...
- x1 = 2
- y1 = -3
- x2 = 6
- y2 = 4
Using these values in the given formula, we find the slope to be ...
The slope of the line through the given points is 7/4.
