Well from what I understand about the question, it's asking if there only needs to be 1, how many can there be. so 9
Answer:
the domain is that x is a set of real numbers.
the range is y ≤ -3
Step-by-step explanation:
y = -|x + 3|
y is either positive or equal to zero.
Now, x is all real numbers because any value of x used will yield a valid value of y.
Thus, we can say that the domain is that x is a set of real numbers.
Now, for the range:
The minus sign in front of the absolute value indicates that the function has a maximum value.
Thus, the range is y ≤ -3

Answer:
Systematic-sampling method is the right answer.
Step-by-step explanation:
A method of sampling in which the sample members are selected from a larger population according to a random starting spot but with a fixed, interval, is known as the systematic sampling method.
We can use the systematic sampling method in the given situation. Individual sample members are chosen at regular intervals from the sampling data. We use to chose the intervals to ensure enough sample size. The main advantage of using this method is that it is more convenient and it is easy to administer. The benefit of using this method will be that the number of aspen trees will be sampled from all across the national park.
Answer:
1.16 to 2.75
Step-by-step explanation:
The mean salary (millions of dollars) for shortstops was 1.95.
The population mean for all baseball players was 1.85
The population standard deviation was 1.61.
Formula of confidence interval :
to 
z at 95% confidence level = 1.96
Substitute the values in the formula
Confidence interval :
to 
Confidence interval : 1.16 to 2.75
Hence the 95 percent confidence interval for these data is 1.16 to 2.75
