Well 4 out of the 5 are odd.  So the probability the first digit is odd is (4/5) since that digit is no longer available, then the probability the second digit is odd is (3/4), then for the third (2/3), then the forth (1/2).

So to find the first four being odd is (4/5)*(3/4)*(2/3)*(1/2) = 24/120 = .20

If a train travels 25 miles in 2 hours and 15 minutes, what is it's average speed in miles per hour?
Alexus [3.1K]
2 hours 15 mins = 2 1/4 hours

2 1/4 hours = 25 miles

1 hour = 25 ÷ 2 1/4 = 25 ÷ 9/4 = 25 x 4/9 = 11.1 miles

Answer: 11.1 mph

Factor 4x^2 + 1x – 13
bulgar [2K]

Answer:

(x - \frac{\sqrt{209} - 1}{8} )(x - \frac{-1 - \sqrt{209} }{8} )

Step-by-step explanation:

<u>FACTS TO KNOW BEFORE SOLVING :-</u>

<em>Quadratic Formula :-</em>

Lets say , there's an equation ax² + bx + c.

=> x = \frac{-b + \sqrt{b^2 - 4ac} }{2a} \: or \: \frac{-b - \sqrt{b^2 - 4ac} }{2a}

<u>SOLUTION :-</u>

According to the question ,

  • a (Coefficient of x²) = 4
  • b (Coefficient of x) = 1
  • c (constant) = -13

By using quadratic formula ,

x = \frac{-1 + \sqrt{1^2 - 4 \times 4 \times (-13)} }{2 \times 4} \: or \: \frac{-1 - \sqrt{1^2 - 4 \times 4 \times (-13)} }{2 \times 4}

=> x = \frac{-1 + \sqrt{209} }{8} \: or \: \frac{-1 - \sqrt{209} }{8}

=> (x - \frac{\sqrt{209} - 1}{8} ) \: and \: (x - \frac{-1 - \sqrt{209} }{8} ) are the factors of 4x² + x - 13.
