Answer:
299/2800=0.1067857
0.1067857 x 100% = 10.67857%
Step-by-step explanation:
Proof:
Multiply both of the sides by 3. You would get 12d = c - d. Add d on both sides, and you would get c = 12d
Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-
![Z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=Z%3D%5Cdfrac%7B%5Coverline%7Bx%7D-%5Cmu%7D%7B%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
, where
= Sample mean ,
= population mean,
= population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,
![z=\dfrac{ 31650-29056}{\dfrac{3339}{\sqrt{10}}}\\\\=\dfrac{2594}{\dfrac{3339}{3.16227766017}}\\\\=\dfrac{2594}{1055.88451073}=2.45670807142\approx 2.46](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B%2031650-29056%7D%7B%5Cdfrac%7B3339%7D%7B%5Csqrt%7B10%7D%7D%7D%5C%5C%5C%5C%3D%5Cdfrac%7B2594%7D%7B%5Cdfrac%7B3339%7D%7B3.16227766017%7D%7D%5C%5C%5C%5C%3D%5Cdfrac%7B2594%7D%7B1055.88451073%7D%3D2.45670807142%5Capprox%202.46)
Hence, the z-score = 2.46
Answer:
