The intermediate answers from some calculations based on whole number scores are X=4.3467892 and Y=3.3333. We now want to find X(2)+Y(2). After rounding, what values of X and Y do we use?
To find X(2)+Y(2), we first need to understand the given information. The intermediate answers for X and Y are X=4.3467892 and Y=3.3333. However, we are asked to use rounded values for the final calculation.
Rounding involves adjusting a number to a specified decimal place. In this case, we don't have any specific instructions on how many decimal places to round to, so we will round both X and Y to the nearest whole number.
To round a decimal number to the nearest whole number, we look at the decimal portion and round it based on whether it is less than 0.5 or greater than or equal to 0.5.
For X=4.3467892, the decimal portion is 0.3467892. Since this is less than 0.5, we round down to the nearest whole number. Thus, X becomes 4.
For Y=3.3333, the decimal portion is 0.3333. Again, this is less than 0.5, so we round down to the nearest whole number. Therefore, Y becomes 3.
Now, we can substitute the rounded values into the expression X(2)+Y(2):
X(2)+Y(2) = 4(2) + 3(2) = 8 + 6 = 14
Therefore, the final value of X(2)+Y(2) after rounding is 14.
