Data accumulated by the National Climatic Data Center shows that the average wind speed in miles per hour for St. Louis,Missouri

Marat540 [252]

Answer:

The value is $\sigma = 8.5$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 9.7$

The proportion is $P(X >x) = 0.2245$

The value considered is $x = 11.6$

Generally given that the speed measurement is normally distributed we have that

$P(X > 11.6) = P(\frac{ X - \mu }{ \sigma } > \frac{11.6 - 9.7}{ \sigma } ) = 0.2245$

Generally

$\frac{X - \mu}{ \sigma } = Z(The \ z -score \ of \ X )$

$P(X > 11.6) = P(Z> \frac{11.6 - 9.7}{ \sigma } ) = 0.2245$

Hence

$\frac{ 11.6 - 9.7}{ \sigma} = 0.2245$

$\sigma = 8.5$

Solve for x<br><br> 2/7x = 6<br><br> (SHOW YOUR WORK)

castortr0y [4]

Answer:

The answer to your question is x = 21

Step-by-step explanation:

Equation

$\frac{2}{7} x = 6$

- Multiply both sides by 7

$\frac{(2)(7)x}{7} = 6(7)$

- Simplify

2x = 42

- Divide both sides by 2

$\frac{2x}{2} = \frac{42}{2}$

- Simplify

x = 21
