The United States Marine Corps is reviewing its orders for uniforms because it has a surplus of uniforms for tall men recruits a
Vlad [161]

Answer:

69.7 -2.58 \frac{2.8}{\sqrt{772}}=69.44

69.7 +2.58 \frac{2.8}{\sqrt{772}}=69.96

And we can conclude that the true mean for the heights of mens between the ages of 18 to 24 is between 69.44 and 69.7 inches.

Step-by-step explanation:

For this case we have the following sample size n =772 from men recruits between the ages of 18 to 24

\bar X= 69.7 represent the sample mean for the heigth

\sigma=2.8 represent the population standard deviation

We want to construct a confidence interval for the true mean and we can use the following formula:

\bar X \pm z_{\alpha/2} \frac{\sigma}{\sqrt{n}}

The confidence level is 0.99 or 99%o then the significance level is 0.01 and \alpha/2 =0.005 and if we find for a critical value in the normal tandar ddistirbution who accumulates 0.005 of the area on each tail we got:

z_{\alpha/2}= 2.58

And replacing we got:

69.7 -2.58 \frac{2.8}{\sqrt{772}}=69.44

69.7 +2.58 \frac{2.8}{\sqrt{772}}=69.96

And we can conclude that the true mean for the heights of mens between the ages of 18 to 24 is between 69.44 and 69.7 inches.

4x+3y=12
77julia77 [94]

Answer:

B, C, F

Step-by-step explanation:

Given:

\left\{\begin{array}{l}4x+3y=12\\ \\2x+3y=-6\end{array}\right.

Subtract the second equation from the first equation:

(4x+3y)-(2x+3y)=12-(-6)\\ \\4x+3y-2x-3y=12+6\\ \\2x=18\\ \\x=9

Option B "The x coordinate of the solution is 9" is ture

Substitute it into the first equation:

4\cdot 9+3y=12\\ \\36+3y=12\\ \\3y=12-36\\ \\3y=-24\\ \\y=-8

Option F "The y coordinate of the solution is -8" is true.

Point (9,-8) is in the IV quadrant, so option C is true.
