so is actually bidmas of bodmas however you want to call it but what's in the brackets you always have to do first so what you would do is because as for subtraction comes last you 1st to -8+10 which is to then you do 2-5 which is -3 so then you do -7 times -3 which because if two minuses or times or multiplied like everyone say it would be a positive so that
It's the answer is 21
Step-by-step explanation:
Given:
Mean population = 289,294
Standard deviation = 461,176
percentage of the population of all counties is within 1 standard deviation of the mean
Let us follow the 68-95-99.7 rule
For the normal distribution<span>, the values less than one standard deviation away from the mean account for 68% of the set; while two standard deviations from the mean account for 95%; and three standard deviations account for 99.7%.
</span>
The percentage of population of all counties within one standard deviation of the mean is 68%
