24

Step-by-step explanation:

There are 36 possible outcomes when rolling 2 dice. The sums range from 2 to 12. There are 4 ways of rolling a 9: 3, 6; 4, 5; 5, 4; 6, 3.

p(sum of 9) = 4/36 = 1/9

1/9 of the rolls are expected to have a sum of 9.

1/9 * 216 = 24

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
