The percentage error can be calculated using the following rule:
% error = difference between values / accepted value
From the givens:
The accepted value = 40%
Difference between values = 40% - 37% = 3%
Substitute in the equation to get the percentage error as follows:
% error = (3/40) * 100 = 7.5%
1. upwards
2. minimum -5
3. domain : xER range: y > -5
4) 2x^2 + 4x - 3
Is 3 times the value
I know this because the number 8 is moved to the left 3 times
Answer:
She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.
Step-by-step explanation:
x = amount of 4% fuel
6 - x = amount of 20% fuel
0.04x + 0.2(6 - x) = 0.08(6) Multiply both sides by 100 to remove the decimals
4x + 20(6 - x) = 8(6)
4x + 120 - 20x = 48
-16x + 120 = 48
-16x = -72
x = 4.5
She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.
