The advertisements claim that train is on time 90% of time and the bus have a record 56 out of 64 days . which form of transportation provides best service. explain

Train

Step-by-step explanation:

To get the success rate (on time) of bus, we need to divide 56 by 64. So:

This multiplied by 100 gives us the %. Thus, 0.875 * 100 = 87.5%

Clearly, 90% is greater than 87.5%. Hence, based solely on times, the train provides best service.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
