Hi there!
We can use the discriminant of the quadratic formula to find the number of real solutions to this (or any other quadratic) equation.
The discriminant can be found by plugging in the data from the equation into the following formula:

When we fill in the data from the question we get

Since d < 0 the equation has zero real solutions.
Answer:
21345
Step-by-step explanation:
For distributions that have outliers or are skewed, the median is often the preferred measure of central tendency because the median is more resistant to outliers than the mean.
Answer:
D. 50
Step-by-step explanation:
Answer:
The median is close to 90, but there is most likely one student and up to 25 % of the class who did poorly on an exam that otherwise looks pretty easy
Step-by-step explanation:
Hope this helps you!
