Fudgin [204]

Answer:

It was gained 4 1/4 points.

Step-by-step explanation:

- 7 1/8 - 1 5/8 + 13 = - 8 6/8 + 13 = - 8 3/4 + 13 = - 8 - 3/4 + 12 + 4/4 = 4 1/4

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.

Vita wants to center a towel bar on her door that is 27 1/2 inches wide. She determines that the distance from each end of the t

timurjin [86]

Answer:

The equation is $x+18 =\frac{55}{2}$ ..

The length of the towel bar is $\frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in$ ..

Step-by-step explanation:

Given,

Length of the door = $27\frac{1}{2}\ in$

we can rewrite $27\frac{1}{2}\ in$ as $\frac{55}{2}\ in$ .

We have to find out the length of the towel bar.

Let the length of towel bar be 'x'

`Since Vita wants that the distance from each end of the towel bar to the end of the door to be 9 inches.

So we can say that the length of the towel bar plus from each end of the towel bar to the end of the door plus from each end of the towel bar to the end of the door is equal to length of door.

framing in equation form, we get;

$x+9+9= \frac{55}{2}\\\\x+18 =\frac{55}{2}$

Hence The equation is $x+18 =\frac{55}{2}$ .

Now we solve the equation we get;

Subtracting both side by 18 we get;

$x+18-18=\frac{55}{2}-18\\\\x=\frac{55}{2}-18$

Now we will make the denominator common we get;

$x=\frac{55}{2} -\frac{18\times2}2= \frac{55}{2} -\frac{36}2 = \frac{55-36}{2}=\frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in$

Hence The length of the towel bar is $\frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in$ .

How do i solve for x by using natural log (in)?

Helga [31]

Unfortunately you cannot use logs to solve this.

However, it shouldn't take too long to use guess-and-check to see that

$2^x+3^x = 2^2+3^2 = 4+9 = 13$

Showing that x = 2 is the solution to the equation.

You can use a graphing calculator to graph out $y = 2^x+3^x$ and $y = 13$ . The two curves cross at (2,13). The x coordinate of that intersection is what we're after. GeoGebra and Desmos are two free options you can pick from in terms of a graphing calculator.
