Answer:
11.38.
Step-by-step explanation:
Given :The price of a movie ticket in a given year can be modeled by the regression equation , where y is the ticket price and x is the year.
To Find: . To the nearest cent, which is the best prediction of the price of a ticket in year 25?
Solution:
Where y is the ticket price and x is the year.
Now we are supposed to find which is the best prediction of the price of a ticket in year 25
Substitute x = 25 in the given equation.
Thus the best prediction of the price of a ticket in year 25 is 11.38.
Answer:
Work Shown:
Explanation:
As the steps above show, the goal is to factor the expression under the root in terms of pulling out cubed terms. That way when we apply the cube root to them, the exponents cancel. We cannot factor the y term completely, so we have a bit of leftovers.
