I think the answer is
-9-12=-21
Step-by-step explanation:
62/500 is the proportion of rolling 4 to all the rolls, so we just need to expand the fraction so that the denominator is equal to 3000
3000÷500=6
6*62=372 B
Answer:
Step-by-step explanation:
So if the die has six sides 1,2,3,4,5, and 6 then there are three even numbers in that number set. Three is half of 6 so you will have half the chance of rolling an even number
Answer:
<h2>
Average speed is 15km/h</h2>
Step-by-step explanation:
Step one:
given data:
total distance =7.5km
time taken= 30 min= 0.5 hours
we know that the average speed is the average distance divided by time taken
Step two:
mathematically expressed as
speed=distance/time
substituting we have
speed=7.5/0.5
speed=15km/hour
Hence the average speed is 15km/h
