As, given correlation coefficient for your data set is= -0.015
It means there is weak relation between two variables.If value of correlation coefficient is near to 1 or -1, it shows there is strong correlation.
Negative correlation means, if one quantity is increasing other is decreasing.So, the value of -0.015 shows that there is very less correlation between x and y values or two values in data set.
So, the chances are very less that predicted value will be reasonably close to the actual value as the points will be far from line of best fit.
To find the X intercept, replace y with 0 and solve for x:
9x + 21(0) = 16
9x = 16
x = 16/9
To find the Y intercept, replace x with 0 and solve for y:
9(0) + 21y = 16
21y = 16
y = 16/21
X-intercept is 16/9
y intercept is 16/21

Answer:
- adult: 325
- children's: 225
Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.
