Ok. <span>Population = 100,000 *1.045^n (n is number of years since 1999.
So, the population in 2005 (where n=6) is 130,226

Answer:
$6650
Step-by-step explanation:
→ Calculate the decimal multiplier
100 - 30 = 70
70 ÷ 100 = 0.7
→ Multiply the decimal multiplier by the cost
9500 × 0.7 = 6650
To find the test statistic or z-score given sample number (n), sample mean (x), standard deviation (σ), and population mean (μ), we can use

Given that n = 36, x = 24.6, μ = 20, and σ = 12,


From this, we see that the test statistic is 2.3.
Answer: 2.3
The solution is
y=5.6
hope this helps:)
