Write the prime factorization of 84 using exponents

Katyanochek1 [597]

Answer:

2^2 * 3 * 7

Step-by-step explanation:

First, divide by 2.

84 / 2 = 42

Divide by 2 again!

42 / 2 = 21

21 is divisible by 3, so divide by 3.

21 / 3 = 7

7 is prime, so we've reached the end of our little adventure!

84 = 2 * 2 * 3 * 7, or in exponents, 2^2 * 3 * 7.

Hope that helps!

Mark rolls 2 fair dice and adds the results from each. Work out the probability of getting a total of 5. Please help if you can!

Allisa [31]

Answer:

13.8%

Step-by-step explanation:

I have created a table that shows all of the possibilities that two die's can roll when summed up. If we count all of these possibilities we can see that there are a total of 36 outcomes. From all of these outcomes we can also see that only 4 outcomes sum up to be a total of 5. Therefore, we have to divide the number of times 5 is a possibility by the total number of outcomes to get the probability of actually getting a sum of 5.

5 / 36 = 0.138 ... multiply by 100 to get percentage

0.138 * 100 = 13.8%
