The quadratic regression equation that models these data is y = –0.34x2 + 4.43x + 3.46. using the quadratic regression equation, what was the predicted profit in year 10?

13.76

Step-by-step explanation:

We want year 10; this means we substitute 10 in place of x:

y=-0.34(10²)+4.43(10)+3.46

y = -0.34(100)+4.43(10)+3.46

y = -34+44.3+3.46 = 13.76

Profit in year 10 is 13.76 million dollars.

Step-by-step explanation:

The quadratic regression equation that models the data is y = -0.34x² + 4.43x + 3.46

Here "y" defines the profit in the year and x is the number of years.

We have to calculate the predicted profit in year 10.

We can get the predicted profit from the regression equation by putting the value x= 10.

y = -0.34×(10)² + 4.43(10) + 3.46

  = -34 + 44.3 + 3.46

  = 13.76

Therefore profit generated will be 13.76 million dollars.
