I think that is the mean or the mode . I think more on mean
Answer:

Step-by-step explanation:
Given the quadratic function

Evaluating the quadratic function

substitute x = 3



Therefore,
Answer:
5.20 to the nearest hundredth.
Step-by-step explanation:
The altitude line bisects the base of the triangle to form 2 right angled triangles with hypotenuse = 6 and the base = 3.
So, by the Pythagoras theorem the altitude is calculated as follows:
6^2 = 3^2 + x^2
x^2 = 36 - 9 = 27
x = √27
= 5.20 to the nearest hundredth.
Omg i gave that same question it’s so hard
