what is the X co-ordinate of vertex of parabola where equation is Y is equal to X square + bx + c =\ o

torisob [31]

Answer:

x = - $\frac{b}{2}$

Step-by-step explanation:

Given a quadratic equation in standard form , that is

y = ax² + bx + c = 0 ; a ≠ 0

Then the x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

x² + bx + c = 0 ← is in standard form

with a = 1, b = b, thus

$x_{vertex}$ = - $\frac{b}{2}$

A 95% confidence interval for a population mean, μ, is given as (18.985, 21.015). This confidence interval is based on a simple

creativ13 [48]

Answer:

standard deviation of the sample = s = 3.04

Step-by-step explanation:

given,

μ, is given as (18.985, 21.015)

sample mean = $\dfrac{(18.958+21.015)}{2}$

=19.9865

margin of error = 19.9865 - 18.958 =1.0285

The degree of freedom = n -1 = 36 - 1 = 35

a = 0.05, t(0.025, df = 35) = 2.03 (from student t table)

margin error = $\dfrac{t\times s}{\sqrt{n}}= 1.0285$

= $\dfrac{2.03 \times s}{\sqrt{36}}= 1.0285$

= $\dfrac{2.03 \times s}{6}= 1.0285$

= $s = \dfrac{1.0285\times 6}{2.03}$

= s = 3.04

standard deviation of the sample = s = 3.04
