Solve by completing the square: 6x^2+39=5+12x
Marta_Voda [28]
6x^2-12x=-34
x^2-2x=-34/6
x^2-2x=-17/3

x^2-2x+1= -17/3+1/1
x^2-2x+1= -14/3

(x-1)^2= -14/3
x-1= √-14/3

Final answer: No solution (you cannot find the root of a negative number)

The Chartered Financial Analyst (CFA) designation is fast becoming a requirement for serious investment professionals. Although
Vikki [24]

Answer: (145820, 170180)

Step-by-step explanation:

Formula for confidence interval for population mean ( when population standard deviation is unknown ) :

\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}

, where n= sample size

\overline{x} = sample mean

s= sample standard deviation

t_{\alpha/2}= two-tailed t-value for significance level of (\alpha).

We assume that  the salary of CFA charterholders is normally distributed .

Let x represents the salary of CFA charterholders .

As per given , we have

n=  36

\overline{x}=\$158,000

Degree of freedom : df = 35    [ df= n-1]

s=  $36,000

Significance level : \alpha=1-0.95=0.05

Using t-distribution table ,

t_{\alpha/2, df}=t_{0.025,\ 35}=2.030

95% confidence interval for the average salary of a CFA charterholders :-

158000\pm (2.030)\dfrac{36000}{\sqrt{36}}\\\\=158000\pm 12180\\\\=(158000-12180,158000+12180) =(145820,\ 170180)

Hence, the 95% confidence interval for the average salary of a CFA charterholder : (145820, 170180)
