Use the quadratic formula to determine the exact solutions to the equation 6x^2 + 4x - 3 = 0

mezya [45]

To solve quadratics, the most correct and effective way, in my opinion, is the quadratic formula:

$x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}.$ 

Plugging it in, we get:

 $\frac{-4\pm \sqrt{16+72} }{12} = \frac{-4\pm 2\sqrt{22}}{12} = \frac{-2\pm \sqrt{22} }{6}$

So the final answer is:

$\frac{ \sqrt{22}-2 }{6}$ and $\frac{-2- \sqrt{22} }{6}$

13. Jessica has taken 8 quizzes. The mean of her scores is 92. Her first 6 scores are shown.

Dovator [93]

Answer: Median= 91; 8th quiz score=86

Step-by-step explanation: The sum of the scores is 8×92=736. Subtract the 6 given scores and then a 100 for the seventh quiz to find the score she got on the 8th quiz, this is an 86. Now that you have all the scores, arrange them all in the least to greatest order and find the average of the middle two numbers (median), which is 91!
