Answer:

The correct answer is "1668". A further solution is provided below.

Step-by-step explanation:

According to the question,

Estimated proportion,

\hat{p} = \frac{574}{1007}

  =0.57

Margin of error,

E = 0.02

Level of confidence,

= 90%

= 0.90

Critical value,

Z_{0.10}=1.65

Now,

⇒  0.02=1.65\times \sqrt{\frac{0.57\times 0.43}{n} }

 0.0004=2.7225\times \frac{0.2451}{n}

         n=\frac{2.7225\times 0.2451}{0.0004}

             =1668.21

or,

         n \simeq 1668

The graph models the function y = −x2 − x + 6. Which attribute(s) of the graph tell you the root(s) of the function? Determine t
Alex73 [517]
In a graph the roots of the function are given by the cut points with the x axis.
 On the other hand, we have the following equation:
 y = -x2 - x + 6
 To find the roots, we equate to zero:
 -x2 - x + 6 = 0
 Rewriting we have:
 x2 + x - 6 = 0
 (x-2) (x + 3) = 0
 The roots are:
 x1 = 2
 x2 = -3
 Answer:
 
The roots are:
 
x1 = 2
 
x2 = -3
