At an amusement park, a lemonade stand was next to a roller coaster. Throughout the day, people who got off the ride and purchas
ed lemonade were asked how long theyhad to wait in line for the roller coaster. The results are shown in the scatter plot below.
Which statement is supported by the data in the scatter plot?
As the wait time increases, the number of cups of lemonade sold tends to stay the same.
There is no relationship between the wait time and the number of cups of lemonade sold.
As the wait time increases, the number of cups of lemonade sold tends to decrease.
As the wait time increases, the number of cups of lemonade sold tends to increase.

4. Sometimes
Step-by-step explanation:
1. Quadratic function : in which maximum power of is two.
The roots of quadratic function can be either equal or different.
For example:
will have two equal roots i.e. 1 and 1.
will have two different roots i.e. 1 and 2.
So, <em>sometimes </em>is the correct answer.
2. Cubic function has atleast 1 real root.
Cubic function has maximum power of as 3.
If the coefficients are real numbers then atleast 1 real root.
If the coefficients are imaginary in nature, then this is not true.
For example:
Cubic equation does not have any real root.
Cubic equation has a real root x = -1.
So, it is sometimes true.
3. A function with degree 5 i.e. maximum power of as 5 will have 5 roots.
It is always true that a function will have number of roots equal to its degree.
4. Quadratic function can have only 1 complex solution.
Two complex solutions are also possible for a quadratic function.
For example:
will have two imaginary roots:
It is also possible to have 1 complex solution,
For example:
will have one complex root and one real root.
So, the statement is <em>sometimes </em>true.
