Answer:
D. 0.857
Step-by-step explanation:
The coefficient of determination, R-squared, is simply the square of the correlation coefficient;
R-squared = r^2
R-squared = 0.926^2
R-squared = 0.857
Therefore, the coefficient of determination is 0.857.

Answer:
112 adult and 288 children
Step-by-step explanation:
x= adult seats
y= children seats
15x + 10y = 4560
x + y = 400 --> y=400-x
so plug 400-x for y in the other equation
15x + 10(400-x)= 4560
now solve this equation
15x + 10(400-x)= 4560 --> 15x + 4000-10x= 4560 --> 15x -10x = 560 --> 5x=560 --> x = 560/5 --> x= 112
now plug in 112 for this equation (x+y=400) --> 112+y=400 --> y= 288
