If you take wha it says and plug it in, it makes the most sense
Answer:
I think 155 is a answer and thanks for point
Alright, let's interpret it, first.
The question is asking us to first find two percent of 23,000, then right an equation.
Alright, first, let's find two percent of 23,000. To find that we must do 0.02*23,000
I got 460
So we know that Mastertown's population is increasing by 460 people per year. All we have to do now is plug that into the equation.
Population (y)= 460* amount of years (x)
So our final equation is y = 460x
Hope this helped! Ask any questions about it!
Take the sqrt of both sides of <span>(x+2)^2=10:
x+2 = plus or minus sqrt(10)
Solve for x: x = -2 plus or minus sqrt(10)
Evaluate x: x = -2 + sqrt(10) AND x = -2 - sqrt(10) (answers)

Answer:
At least 68% of observations lie between 22 and 26 months.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 24
Standard deviation = 2
22 = 24 - 2
22 is one standard deviation below the mean
26 = 24 + 2
26 is one standard deviation above the mean.
So, by the empirical rule, at least 68% of observations lie between 22 and 26 months.
