True: The theoretical  probability of drawing a diamond is 25%. Since there are the same number of cards for each of the four suits, the chance of drawing any suit is 25%.

True: Based on the experimental probability, there would be 90 spades drawn in 500 trials. 0.18 x 500 = 90

The rest of the statements are false.

In simplest radical form, what are the solutions to the quadratic eqaution 0=-3x^2-4x+5
tensa zangetsu [6.8K]

Answer:

x= -\frac{2+\sqrt{19} }{3} \textrm { and } x = -\frac{2-\sqrt{19} }{3}

Step-by-step explanation:

We have to find the solution of the quadratic single variable equation as given below:

- 3x² - 4x + 5 = 0 ..... (1)

The left-hand side can not be factorized.

So, apply The Sridhar Acharya Formula, which gives if ax² + bx + c = 0,the the solutions of the quadratic equation are

x=\frac{-b + \sqrt{b^{2} -4ac} }{2a} and, x=\frac{-b - \sqrt{b^{2} -4ac} }{2a}

So, from the equation (1), we can write  

x= \frac{-(-4) +\sqrt{(-4)^{2}-4 \times (-3) \times 5 } }{2 \times (-3)} and

x= \frac{-(-4) -\sqrt{(-4)^{2}-4 \times (-3) \times 5 } }{2 \times (-3)}

⇒ x=\frac{4+ 2\sqrt{19} }{-6} \textrm{ and } x=\frac{4-2\sqrt{19} }{-6}

⇒ x= -\frac{2+\sqrt{19} }{3} \textrm { and } x = -\frac{2-\sqrt{19} }{3} (Answer)

What you do is 20 divided by 4, which is 5. So then you times 32 by 5 and that's how you get 160.
