Answer:
C.
Step-by-step explanation:
The “training” data set is the general term for the samples used to create the model, while the “test” or “validation” data set is used to qualify performance. Perhaps traditionally the dataset used to evaluate the final model performance is called the “test set”.
Answer:
The solutions are x=4, y=3. Cashews are $4 per pound and Peanuts are $3 per pound.
Step-by-step explanation:
let x = cashews
let y = peanuts
x + 2y = 10 - rosa's purchase
2x + y = 11 - sabrina's purchase
subtract 2x to isolate 'y'
y = 11 - 2x
x + 2(11 - 2x) = 10
x + 22 - 4x = 10 (Use the distributive property.)
-3x = -12
x = 4.00
Plug this into the original equations to find "y"
2(4) + y = 11
8 + y = 11
y = 3
4 + 2y = 10
2y = 6
y = 3
the solutions are: x = 4. y = 3.
The original number is 15.
Let’s work it out.
First, divide.
21 divided by 3 is 7.
Now, add.
8 + 7 = 15
This is true because...
15 - 8 = 7
Hope this helps, have a great day, stay safe and positive.
