Using the Formula n=1/(ME)2 to Determine Sample Size When we want confidence and use the conservative estimate of , we can use t

PIT_PIT [208]

Answer:

The sample size needed is 40000.

Step-by-step explanation:

The sample size needed is:

$n = \frac{1}{M^{2}}$

Use this formula to determine the sample size needed for a margin of error of 0.005

This is n when $M = 0.005$ . So

$n = \frac{1}{M^{2}}$

$n = \frac{1}{0.005^{2}}$

$n = 40000$

The sample size needed is 40000.

F(x) = 5x2 – 20x + 26<br> In vertex form

mihalych1998 [28]

Answer:

$f(x)=5(x-2)^{2}+6$

Step-by-step explanation:

we have

$f(x)=5x^{2} -20x+26$

This is the equation of a vertical parabola open upward

The vertex is a minimum

The equation of a vertical parabola in vertex form is equal to

$f(x)=a(x-h)^2+k$

where

(h,k) is the vertex

Convert the given function to vertex form

Factor the leading coefficient

$f(x)=5(x^{2} -4x)+26$

Complete the square

$f(x)=5(x^{2} -4x+4)+26-20$

$f(x)=5(x^{2} -4x+4)+6$

Rewrite as perfect squares

$f(x)=5(x-2)^{2}+6$ ------> equation in vertex form

The vertex is the point (2,6)
