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.

Answer:

25.9 yd

Step-by-step explanation:

a^{2} + {b^{2} }  = c^{2}

(17)^{2} + {b^{2} } = (31)^{2}

289 + {b^{2} }  = 961

Subtract 289 on both sides

{b^{2} }  = 672

\sqrt{b^{2} } = \sqrt{672}

nearest tenth

b = 25.9 yd

Answer:

x = 90

Step-by-step explanation:

The 90-degree angle and "x" form a straight line. The degree measurement of a straight line is 180. That means that if one adds 90 and "x", they will get 180, and therefore, x equals 90.
