Answer:
Step-by-step explanation:
You can obtain the regression equation using minitab software ...
First step:
Choose stat then select regression and regression
Next step:
In Response, enter the column containing the response (Y) variable as Cost.
Next step :
In Predictors, enter the columns containing the predictor (X) variables as Summated Rating.
Final step :Click OK.
Then you get your answer
The formula for the area of a triangle is (base × height)/2. We know that the height is 9, so we can reverse the formula:
(base × 9)/2 = 54
× 2
base × 9 = 108
÷ 9
base = 12
So your answer is 12m. I hope this helps!
Answer:
y = (x +4)(x +2)²(x +1)
Step-by-step explanation:
The function has a generally U shape, so is of even degree. The zero where the graph touches, but does not cross, the x-axis is a zero of even multiplicity. The minimum degree of a function that matches this description is 4. It will have zeros at x=-4, -2 (multiplicity 2), and -1. The constants in the corresponding binomial factors will be the opposite of these values, so the factored form is ...
y = (x +4)(x +2)²(x +1)
__
The multiplicity of a zero is the power of the corresponding factor.
Answer:
x =4
Step-by-step explanation:
3x - 2 = 10
Add 2 to each side
3x -2 + 2 = 10+2
3x =12
Divide by 3
3x/3 =12/3
x =4
