If 3x^2-2x+7=0 then (x-1/3)^2=

1 answer:

5 0

3x^2−2x+7=0
3x^2−2x+1/3+7−1/3=0
3(x^2−2x/3+1/9)+7−1/3=0
3(x−1/3)^2+(21−1)/3=0
3(x−1/3)^2=−20/3
(x−1/3)^2=−20/9

Step-by-step explanation:

Confidence Interval

When the population standard deviation $\sigma$ is known, the formula for a confidence interval for a population mean $\bar x$ is:

$\displaystyle \bar x \pm z\frac{\sigma}{\sqrt{n}}$

Where n is the sample size and z is the corresponding z-value from the standard normal distribution for the selected confidence level. The value of z for a 95% confidence interval is z=1.96. The rest of the values are

$\bar x=28.2,\ \sigma=2.7, \ n=10$

Calculating the confidence interval

$\displaystyle 28.2 \pm 1.96\frac{2.7}{\sqrt{10}}$

$\displaystyle 28.2 \pm 1.6735$

Or, equivalently

$26.5265$
