No, because when you have your problem it can be less or more so it can't always be the same. Hope I helped.

The <em><u>correct answer</u></em> is:

Yes, it must.

Explanation:

Rational numbers are closed under subtraction. This means that if you subtract two rational numbers, your answer will also be a rational number.

The only way you could have two rational numbers and end with a result that is <em>not</em> a rational number is to take the square root of at least one of them. Depending on the digits in the numbers, this would result in an irrational number.

You roll a six-sided die twice. What is the probability of rolling an even number and then an odd number?
nlexa [21]

Answer:

C) 1/4

Step-by-step explanation:

Because you have six-sided dice there are 3 odd numbers and 3 even numbers. That means you have a 1/2 for getting either a odd or even number. So we would add 1/2 + 1/2 because you are rolling two times and both have a 1/2 of getting either a odd or even number. 1/2+1/2 = 1./4 which would be your answer.

Hope this helped! Have a good day/night and good luck! Stay safe!!

Megan considers two different car rental options. One option costs $19 per day plus $0.12 per kilometre. Another option costs $4
Otrada [13]

Answer:

The $19 car

Step-by-step explanation:

For a one day rental I'd say its pretty average to only be driving for about 160km which is about 100 miles. For those 160km you would only be paying $19. The combined total $38, which is still less than the $42.50 car. The only way this would somewhat equal out is if you drove 200km or 124 miles. That would make the total cost exactly $43. If Meghan plans on driving equal to or more than 200km then she should choose the $42.50 car. In my opinion the $19 should be enough for 1 day.
