The domain of given function is: -3≤x≤3
Step-by-step explanation:
The domain is the set of all possible inputs of the graph. In a graph, the input values are plotted on x-axis and the output or range is plotted on y-axis.
In the given figure we can see that the x-values that are involved in the graph of function are between -3 and 3. So the domain of the function will be:
-3≤x≤3
Hence,
The domain of given function is: -3≤x≤3
Keywords: Domain, Range

39? i think.....pretty sure yeah???
Answer:
<h3>25%</h3>
Step-by-step explanation:
Total number of student in the school = 152 students
Number of student that have more than one pet = 38
percentage of the students have more than one pet will be expressed as
% of student with more than 1 pet = number of student with more than one pet/total number of student * 100%
% of student with more than 1 pet = 38/152 * 100
% of student with more than 1 pet = 3800/152
% of student with more than 1 pet = 25%
Hence 25% of the students in the school have more than one pet.

Answer: (B)
Step-by-step explanation:
An independent sample test compares two sample means in order to determine the statistical significance of the difference between their population means.
The independent sample test would be the best hypothesis test for this study because:
1. There was a random samples of data from the population
2. There was no relationship between the subjects in each sample. That is;
- subjects in the first group were not also in the second group
- subjects in the first group did not influence subjects in the second group and vice versa.
3. There was independence of observations in this study. Each subject in each group was separately observed and each subject has a given fitness performance score.
4. There are values on both the dependent and independent variables.
- the dependent variable is FITNESS PERFORMANCE and for each subject, it is dependent on either the OLD EXERCISE PROGRAM or the NEW EXERCISE PROGRAM.
5. Our dependent variable her is a continuous variable as we see from the range of fitness scores. The lowest score is 19 and the highest score is 73. This shows that the variable is continuous. All the other scores fall in between.
6. Our independent variable is a categorical variable. Categorized into OLD EXERCISE PROGRAM and NEW EXERCISE PROGRAM.
