Bas_tet [7]

Answer:

It should be reported as 20.648%

Step-by-step explanation:

Since we have 2 different observed values hence we shall use an average of the 2 values to report the result

Thus value is $\frac{19.564+21.731}{2}=20.6475%$

As we can see that the least count of our observations is upto 3 decimal places hence we have to report a result upto only 3 decimal places thus we need to round off the fourth decimal place thus the digit shall be increased by 1 since we have to drop off 5 and the digit before 5 is 7 which is an odd number.

Thus the result shall be 20.648%

Select the rational expression that is equivalent to the given expression below. 4 over x - 3

Ad libitum [116K]

When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number: $\frac{1}{3}$ . in our rational number the denominator is 1, and the numerator is 3

Now, a rational expression is an algebraic expression in a rational for. If we apply the same to your problem. 4 over x-3 means 4 divided by x-3, or in mathematical notation: $\frac{4}{x-3}$ . In this case, the numerator is 4, and the denominator is $x-3$ .

We can conclude that the equivalent rational expression of <span>4 over x - 3 is </span> $\frac{4}{x-3}$ .
