Given quadratic equationx^2+6x+6=0
Using the usual conventions, 
a=1, b=6, c=6
Apply the quadratic formula,
x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}
substitute a,b & c with numerical values,
x=\frac{-6\pm\sqrt{6^2-4(1)(6)}}{2(1)}
simplify:
x=\frac{-6\pm\sqrt{12}}{2}

A stockbroker has kept a daily record of the value of a particular stock over the years and finds that prices of the stock form
amid [387]

Answer:

$12.43

Step-by-step explanation:

Given :

Mean = $8.52

Standard deviation, = $2.38

Stock price which falls beyond 0.05 of the distribution is at the 95th percentile

The 95th percentile distribution has a Pvalue of 1.645 (standard normal table)

We obtain the value of x, with z = 1.645

Using the Zscore relation :

Zscore = (score - mean) / standard deviation

1.645 = (score - 8.52) / 2.38

Cross multiply :

1.645 * 2.38 = score - 8.52

3.9151 = score - 8.52

Score = 8.52 + 3.9151

Score = $12.4351

Stock price beyond 0.05 is $12.43
