Answer:

x1 = 2 -\sqrt{5}

x2= 2 +\sqrt{5}

Step-by-step explanation:

x/4 + 6 = 7 + 1/4x

(x^2 - 1)/4x = 1

x^2 - 1 = 4x

x^2 - 4x -1 = 0

x= (4+\sqrt{20})/2 = 2 -\sqrt{5}

x= 2 +\sqrt{5}

The scores of a given test were normally distributed
julsineya [31]

Answer:

The standard deviation is 6

Step-by-step explanation:

The scores of a given test were normally distributed  with a mean of 82.

\mu = 82

James received a 67 with a z-score of  -2.5

Z score = -2.5

\bar{x}=67

Formula :Z=\frac{x-\mu}{\sigma}

-2.5=\frac{67-82}{\sigma}

\sigma = \frac{67-82}{-2.5}

\sigma =6

Hence The standard deviation is 6
