Answer:

Option (A) int expressions are always computed exactly; but float expressions can suffer round-off error.

Explanation:

Round - Off Error can be defined as the digital computers have limitations on denoting the decimal numbers, due to this the floating point numbers have to be rounded off or even it is represented exactly after the calculation on the numbers the resulting number has to be adjusted / rounded off according to the specified precision. The resulted number has to be rounded off back to the required precision, this leads to the round off errors in digital computers. As integers don't need to go through the rounding off in computers, the integer numbers don't have round off errors, only floating point numbers have round off errors. So, options (B) , (C) and (D) are false.

Answer:

Option D: monthName.splice(2, 3, "Mar", "Apr", "May");

Explanation:

splice is a JavaScript array method which can be used to insert or remove item(s).

It has general syntax: splice( i, n , item1, item2, item3, .... , itemX)

i : index position of the array where the item should be inserted or removed
n: number of item(s) should be removed starting from index-i
item1,item2,....itemX : item(s) to be inserted

If we have an original monthName array with elements:

["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]

monthName.splice(2, 3, "Mar", "Apr", "May") will

remove 3 items from index position-2 ("March", "April" and "May")
and insert three new items, "Mar", "Apr" and "May".

New array:

["January", "February", "Mar", "Apr", "May", "June", "July", "August", "September", "October", "November", "December"]

Which column and row references are updated when you copy the formula f$3/15

Tasya [4]

Answer: Column F

Explanation: In Microsoft excel, for the sake of robustness and to aid the effectiveness of updating formulas across cells. The reference of cells are treated as relative which means that when formulas are copied across columns or within rows, they get updated automatically. However, some numbers may be treated as constants such that we do not want them to change or be updated as we move acisss cells. Thus, such numbers are treated Given absolute references, which is made possible by adding a '$' prefix before the colum alphabet or row number or both. in the scenario given above, the row has the $ prefix, hence, it is absolute and will not change but the column alphabet does not and hence, treated as relative.
