To be reasonable means to be as much as is appropriate or fair . In math, reasonableness can be defined as checking to verify that the result of the solution or the calculation of the problem is correct or not, be either estimating or by plugging in your result to check it.
What does reasonable answer mean?
1 showing reason or sound judgment . 2 having the ability to reason. 3 having modest or moderate expectations; not making unfair demands.
Can an answer be incorrect if it looks reasonable?
Can an answer be incorrect if it looks reasonable? Explanation: Yes, an answer can be incorrect even if it looks reasonable, for two main reasons: The assumptions (premises or statements) on which the reasoning is based are wrong.
How can you estimate products by rounding and determine if exact answers are reasonable?
To be reasonable means to be as much as is appropriate or fair . In math, reasonableness can be defined as checking to verify that the result of the solution or the calculation of the problem is correct or not, be either estimating or by plugging in your result to check it.
Is the answer from Problem #3 reasonable explain?
Is the answer from problem #3 reasonable? Explain. Yes . Any yield under 100% is reasonable under the law of conservation of mass.
How does estimating an addition problem help you know if an answer is reasonable?
You can use estimation to check for reasonableness when you have math problems with all numbers. When you do use estimation, it won’t tell you whether you actually have the correct answer, but it will tell you if you’re close and your answer is probably right.
How do you determine which place value to use when estimating products?
To estimate the result of multiplication (product), round the numbers to some close numbers that you can easily multiply mentally. One method of estimation is to round all factors to the biggest digit (place value) they have .
How do you estimate the product by rounding to the highest place value?
Round both numbers to the nearest hundred. Then subtract the rounded numbers. To estimate a Product, round each factor to its highest place value. Then multiply these rounded factors.
How do you estimate and multiply?
Lesson Summary
The general rule for estimating is to look at the digit to the right of the digit you want to estimate . Estimating or rounding to the nearest whole number means looking at the digit to the right of the decimal. If you see a digit greater than 5, round up, and if it’s less than 5, round down.
What is a reasonableness test?
The reasonableness standard is a test that asks whether the decisions made were legitimate and designed to remedy a certain issue under the circumstances at the time . Courts using this standard look at both the ultimate decision, and the process by which a party went about making that decision.
How do you know that the answer to a decimal subtraction problem is reasonable?
The answer should be less than the minuend, which is the number where we subtracted from. To check that it is reasonable, add the difference to the subtrahend which should result in the minuend .
What is the legal definition of reasonable?
Just, rational, appropriate, ordinary, or usual in the circumstances. It may refer to reasonable care, cause, compensation, doubt (in a criminal trial), and a host of other actions or activities.
Which of the following is the most reliable estimate?
Answer: The Detailed Estimation is the most reliable estimation. The Estimate implies a rough estimate of the costs that are expected to be incurred for different pieces of work to be completed.
Why is estimation useful when finding actual products and solving real world problems?
Answer: Estimation helps you check your answer by seeing if the estimate is close to the result you got . You can also estimate first to know approximately what result you should expect to get.
What is the compensation method in math?
Compensation is a mental math strategy for multi-digit addition that involves adjusting one of the addends to make the equation easier to solve . Some students may prefer this strategy as an alternative to left-to-right addition or the breaking up the second number strategy.
What are two ways to estimate?
There are different methods for estimation that are useful for different types of problems. The three most useful methods are the rounding, front-end and clustering methods .
