Explanation

The model shown (– – – → + +) suggests starting with a negative and ending with a positive result.

–2 + 3 = 1, which matches that transition from negative to positive.

Explanation

The initial population is 2¹⁶ insects.

If the population doubles, the new population will be 2 * 2¹⁶ = 2¹⁷.

Explanation

To find when Mubashir and Ali will both exercise on the same day again, we need to calculate the Least Common Multiple (LCM) of their exercise days:

Mubashir: every 8 days

Ali: every 4 days

LCM of 8 and 4 = 8

They will both exercise again on the same day after 8 days.
