Answer: The coefficient of determination = 0.6291
Step-by-step explanation:
Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.
The coefficient of determination is computed as:
Substituting given values, we get
Therefore, the coefficient of determination = 0.6291
Answer:
3x + 2y - 5 = 0
Step-by-step explanation:
Standard form: ax + by + c = 0
2y = -3x + 5
+3x - 5 to both sides
2y + 3x - 5 = 0
Change order.
3x + 2y - 5 = 0
The variable 'a' represents how much Arthur saves. Because D'John saves $8 per week (7 days), he saves $56. Arthur saves four times more than D'John so $56*4 equals Arthur's total savings for the week; $224.
a=$8(7)*4
a=$56*4
a=$224
Answer:
x=0
y=8
Step-by-step explanation:
This is a simultaneous equation
So let's solve
y=-8x+8..(1)
y=-8x+8...(2)
Add (1) and (2)
2y=16
Make y the subject of formula by dividing both sides by 2
y=8
Substitute the value for y into (2)
8=-8x+8
Collect like terms
8-8=-8x
0=-8x
Divide both sides by-8
x=0
Therefore x is 0 and y is 8
