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%.

The percentage of population of all counties within one standard deviation of the mean is 68%

Answer:
equation : 2x+9-5y=0
Step-by-step explanation:
x and y cut axes at -4.5 and 1.4 respectively
given
when x=0
9-5y=0
y=1.4
When y=0
2x+9=0
x=-4.5
I don’t think it is a function because you can’t have two 0’s on the Y axis it doesn’t work
