To get this percentage, divide costs by total food sales
2250 / 25000 = 0.09
then multiply by 100 to get the % = 9%
Answer:
The percentile that corresponds to an IQ score of 115 is 34.13 %
Step-by-step explanation:
Here, we want to find the percentile that corresponds to an IQ score of 115.
To calculate this percentile, we start with making observations. From the question, we are told that the mean score is 100 while the standard deviation is 15.
Now we want to find the percentile for a score if 115. For a score of 115, we can see that the difference between this score and the mean is 15 which is exactly equal to the standard deviation.
What this means is that the score is within +1 SD of the mean.
For a score of within +1 SD of the mean, the percentile is 34.13%
A score at the mean is the 50th percentile, a score which is 1 SD above or below the mean has a percentile value of 34.13%
Please, I will like you to check the attachment to see how percentiles are valued given the number of standard deviations a particular value is from the mean.
Answer:
THIS MAKES NO SENCE
Step-by-step explanation:
Well, for method one the first step we have is distribution, then combining like terms, then property of subtraction, then division. For method two, I'm not entirely sure what they did there. I've never done math like that. Sorry I can't help you out all the way.
