She is not correct. All integers are rational numbers.
We can solve problems like this using multiplication rules. Since the order of colors and combinations does not matter, we can multiply all values in any order we so choose. In this case, our values are colors and vehicles:
Car: Red, Yellow
Truck: Black, White, Silver
Motorcycle: Green, Blue, Orange
We have 2 options with a car, 3 options with a truck, and 3 options with a motorcycle. Since he wants one of each, we will multiply all of the color options together:
2 x 3 x 3
= 18
Edwin has 18 different combination of vehicles to choose from.
There are 60 seconds in one minute, and 60/5=12, so the race car would travel 100 feet every 5 seconds 12 times in one minute. You can simply multiply 100 by 12 to get your answer.
100x12=1200
The race car travels 1,200 feet in one minute.
Answer:
1/4 is the answer.
Step-by-step explanation:
If he has a die then it is 6 sided. He has a 1/2 chance the 1st time that he gets a non-even number. The next time he also has a 1/2 chance of getting an even number so it's 1/2 times 1/2 = 1/4.
