First you need to know how many prime numbers are from 1 to 12.

Prime numbers: 2, 3, 5, 7, 11. There are 5 prime numbers.

The probability of getting a prime number would be 5/12.

Vowels from A to J would be A, E, I, so 3 vowels.

The probability of picking a vowel would be 3/10.

The probability of picking both would be 5/12 x 3/10 = 15 /120, which reduces to 1/8.

The answer is B.

Lisa [10]

Answer:

100% = 30. There are 30 students in Mr.Fulton's class

Step-by-step explanation:

If we have 12 as 40%, we divide it by 2 to get the base value which is 6=20%.

Now we multiply the base by 5 so 20% x 5= 100% and 6 x 5 equals 30. so 100% = 30

I need help -3x=x-(6-2x)?
USPshnik [31]
<span>Simplifying 3x + 6 = 2x
  Reorder the terms: 6 + 3x = 2x
  Solving 6 + 3x = 2x
  Solving for variable 'x'.
  Move all terms containing x to the left, all other terms to the right.
  Add '-2x' to each side of the equation. 6 + 3x + -2x = 2x + -2x
  Combine like terms: 3x + -2x = 1x 6 + 1x = 2x + -2x
  Combine like terms: 2x + -2x = 0 6 + 1x = 0
  Add '-6' to each side of the equation.
6 + -6 + 1x = 0 + -6
 Combine like terms: 6 + -6 = 0
 0 + 1x = 0 + -6 1x = 0 + -6
Combine like terms: 0 + -6 = -6 1x = -6
 Divide each side by '1'. x = -6
 Simplifying x = -6
</span>so the answer is x =-6
