Answer:
Option C) Quadratic regression model
Step-by-step explanation:
Quadratic regression model
- It is regression model in which states a non-linear relationship between the independent and dependent variables.
- It includes the dependent variable and the square of the independent variable.
where x is the independent variable and 
is the dependent variable.
- It is also referred to as second-order polynomial model.
- It is used when the data shape resembles to a parabola.
Thus, the correct answer is
Option C) Quadratic regression model
Answer:
3.48pounds
Step-by-step explanation:
given data
cost of Almonds= $5.2
cost of raisins= $2.75
total cost = $11.7
given that the relationship that represents the cost for the two quantities is
5.20a + 2.75r = 11.70
where a= almond
r= raisin
we are going to substitute a=0.41 in the expression to solve for r
5.20(0.41) + 2.75r = 11.70
2.132+2.75r=11.7
collect like terms
2.75r=11.7-2.132
2.75r=9.568
r=9.568/2.75
r=3.48
Answer:
8.5 × 10^5
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
plot (0,7) then move up 2 because it's positive and keep going up and down the same amount then put the line
