Answer:

Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –2x2 – 2x – 1

Step-by-step explanation:

What are the vertex and axis of symmetry of the equation?

The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

timofeeve [1]

Answer: 0.42

Step-by-step explanation:

Given: Mean : $\mu=954\text{ dollars}$

Standard deviation : $234\text{ dollars}$

Sample size : $n=61$

The formula to calculate z score is given by :-

$z=\dfrac{X-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For X=960

$z=\dfrac{960 -954}{\dfrac{234}{\sqrt{61}}}=0.200262812203\approx0.2$

The p-value = $P(X\geq960)=1-P(X$

Hence, the probability that a single randomly selected value is at least 960 dollars = 0.42
