Answer:
9(s+3.00) + 4s
Step-by-step explanation:
For starters, we s as the basic cost of the shoe. If we buy 4 of those, than it's a simple 4s.
For the other 9 shoes, we have an additional cost of $3. So we will add 3 to s. Since we are buying 9 or those, we will multiple s + 3 by 9. Thus creating the equation above.
It should be $4 sorry if it is wrongbut i pretty sure that is he answer
Answer:
Pearson correlation coefficient
Explanation:
The Pearson correlation coefficient, also simply called correlation coefficient measures the linear correlation between two sets of data/variables, independent variables and dependent variable. A correlation coefficient may only be between -1 and 1 where +1 denotes a perfect positive correlation between variables(both variables increase together), 0 is no correlation, and -1 is perfect negative correlation between variables(one decreases while other increases).
