Answer:
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.
Answer:
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
