Answer: n= number of books
n+5=?
Step-by-step explanation:
The answer to the problem is as follows:
We can convert 4.5% into a decimal form by moving the decimal to the left two places. This becomes: .045

Draw the diameter from point (-1, -5) to point (2, 3).
The triangle has base 3 and height 8.
The diameter of the semicircle is the hypotenuse of the triangle.
![d = \sqrt{3^2 + 8^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B3%5E2%20%2B%208%5E2%7D%20)
![d \approx 8.544](https://tex.z-dn.net/?f=%20d%20%5Capprox%208.544%20)
The radius is half the diameter.
![r = \dfrac{d}{2} = \dfrac{8.544}{2} = 4.272](https://tex.z-dn.net/?f=%20r%20%3D%20%5Cdfrac%7Bd%7D%7B2%7D%20%3D%20%5Cdfrac%7B8.544%7D%7B2%7D%20%3D%204.272%20)
The total area is the area of the triangle plus the area of the semicircle.
![A = \dfrac{bh}{2} + \dfrac{\pi r^2}{2}](https://tex.z-dn.net/?f=%20A%20%3D%20%5Cdfrac%7Bbh%7D%7B2%7D%20%2B%20%5Cdfrac%7B%5Cpi%20r%5E2%7D%7B2%7D%20)
![A = \dfrac{3 \times 8}{2} + \dfrac{\pi \times 4.272^2}{2}](https://tex.z-dn.net/?f=%20A%20%3D%20%5Cdfrac%7B3%20%5Ctimes%208%7D%7B2%7D%20%2B%20%5Cdfrac%7B%5Cpi%20%5Ctimes%204.272%5E2%7D%7B2%7D%20)
Answer:
STEP ONE: 2x
STEP TWO: 5=X (should be the final answer)
Step-by-step explanation:
Hi Lasagna!
So basically, this is extremely simple. In order to "solve" that equation, the x has to be on one side. The easiest way to do this would be to take the 2x to the other side. If you want the 2x to go to the other side, you need to subtract it (since it is already positive, therefore it <em>needs </em>to cancel out). Once you do that, you must always do the same thing to the other side: subtract 2x from 3x. That should get you one x there, which you can just write as x if it's just one. Then you're all set! :D

Calculating the t test statistic
t = (xbar - mu)/(s/sqrt(n))
t = (4.40-4.66)/(0.28/sqrt(6))
t = -2.27452618972722
t = -2.275
The t test statistic is approximately -2.275</span>
