Answer:
Vertex (2 , -25)
Axis of symmetry: x = 2
Step-by-step explanation:
<h3>Vertex of parabola:</h3>
The vertex is the highest point if the parabola open downwards and the lowest point if the parabola opens upward.
f(x) = (x - 2)² - 25
The given quadratic function is in vertex form.
f(x) = a(x - h)² + k
Here, (h , k) is the vertex of the parabola.
h = 2 ; k = -25
<h3>Axis of symmetry:</h3>
The axis of symmetry is the vertical line that divides the parabola into two equal halves and it passes through the vertex of the parabola.
Axis of symmetry: x = h

Answer:
Between 371.6 seconds or 528.4 seconds.
Step-by-step explanation:
Thanks to the normal distribution table (attached) we know that:
95% would be a z between -1.96 and +1.96
z = (x- m) / sd
where x is the value we want to calculate, m is the mean (450) and sd is the set deviation (40). Now, replacing we have:
+ -1.96 = (x-450) / 40
+ -78.4 = x-450
x = 450 + - 78.4
x1 = 528.4
x2 = 371.6
In other words, the result is between 371.6 seconds or 528.4 seconds.
