Answer: 464 km²
Step-by-step explanation:
We will break this shape up into two parts. You can do this in two different ways, see attached for how I did it.
Area of a rectangle is A = L * W;
40 km * 9 km = 360 km²
13km * 8 km = 104 km²
Now we will add them together for total area:
360 km² + 104 km² = 464 km²
Answer:
μ=3.13 (the mean number of residents in the Arizona retirement communities is 3.13)
Step-by-step explanation:
Alternative hypothesis would be:
μ<3.13
Then z-score of the sample of <em>25</em> households in Arizona retirement communities with mean number <em>2.86 </em>residents per household and the standard deviation of <em>1.20</em> residents is calculated under the assumptions of null hypothesis and checked against the critical value of a given significance level.
