Please answer this correctly
klemol [59]

Answer:

50%

Step-by-step explanation:

There are 6 sides on the die. 3 of the sides have even numbers (2,4,6) and 3 of the sides have odd numbers (1,3,5). Since there are the same amount of odd numbers as even numbers on the die, you have an equal chance rolling an even number as you do for an odd number. In other words, you have a 50% chance of rolling an odd number.

Hope this helps! :D

The average depth of the ocean is about
Dafna1 [17]

The height, in meters, of the tallest tower on the Incheon Bridge is 230.5 meters

From the question,

The average depth of the ocean is about 3688 meters.

Also,

To reach this depth, one would have to stack the tallest tower of the Incheon Bridge in South Korea 16 times.

Now, to determine the height, in meters, of the tallest tower on the Incheon Bridge,

We will divide the average depth of the ocean by 16

That is,

The height of the tallest tower on the Incheon Bridge = 3688 m ÷ 16

∴ The height of the tallest tower on the Incheon Bridge = 230.5 meters

Hence, the height, in meters, of the tallest tower on the Incheon Bridge is 230.5 meters
