Answer is $924. First you must multiply 1200 by .3 for the sales tax. Giving you 360. You subtract 360 from 1200 giving you 840. Then you multiple 840 by .1 which gives you 84. You then add 84 to 840 giving you $924.
The greatest common factor of 30, 60, and 75 is 15.
15 x 2 = 30
15 x 4 = 60
15 x 5 = 75
Answer:
3 1/3, or 10/3
Step-by-step explanation:
1 2/3 * 2 = 5/3 * 2 = 10/3 = 3 1/3
No, because only a minority of the students answered it.
<u>Use Chebyshev's Theorem to 88.89 % </u><u> the percentage of gasoline stations that had prices within 3 standard deviation of the mean.</u>
What is the Chebyshev's theorem?
- Chebyshev's Theorem estimates the minimum proportion of observations that fall within a specified number of standard deviations from the mean.
- This theorem applies to a broad range of probability distributions.
- Chebyshev's Theorem is also known as Chebyshev's Inequality.
By Chebyshev's inequality, for any distribution at least
* 100 percentage of values falls within k standard deviation about mean .
here k=3 . Apply this to equation and find percentage that falls within 3 standard deviation about mean.
= 88.89
So, 88.89 % of gasoline station had price within 3 standard deviation about mean .
