Please help , I really need it thanks!

The symbol "<=" without quotes means "less than or equal to"

-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21

So the answer is choice D

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

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

$\sigma = 8.5$
