Ascientist estimated that a mixture would need 4 milliliters of a chemical to balance. the actual amount needed was 7 milliliters. what was the percent error of the scientist's estimation?

The percent error of scientist estimation is 42.85 %

Solution:

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%.

Percentage error is a measurement of the discrepancy between an observed and a true, or accepted value.

The actual amount needed was 7 milli liters and the estimate was 4 milli liters

Plugging in the values in above formula, we get

4x and 6y

im not sure though

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
