In 2008, there were 507 children in Arizona out of 32,601 who were diagnosed with Autism Spectrum Disorder (ASD) ("Autism and de

Svetach [21]

Answer:

The 99% confidence interval for the proportion of ASD in Arizona is (0.014, 0.018).

Step-by-step explanation:

The information provided is as follows:

$x=507\\n=32601\\\text{Confidence level }=99\%$

The sample proportion is:

$\hat p=\frac{x}{n}=\frac{507}{32601}=0.016$

The critical value of <em>z</em> for 99% confidence level is, <em>z</em> = 2.56.

Compute the 99% confidence interval for the proportion of ASD in Arizona as follows:

$CI=\hat p\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}$

$=0.016\pm 2.58\cdot\sqrt{\frac{0.016(1-0.016)}{32601}}\\\\=0.016\pm 0.0018\\\\=(0.0142, 0.0178)\\\\\approx (0.014, 0.018)$

Thus, the 99% confidence interval for the proportion of ASD in Arizona is (0.014, 0.018).

How do get the area. Or how do I even split the shapes

MA_775_DIABLO [31]

Answer:

You spilt up the shapes into triangles, rectangles, squares, etc
The equation for rectangles and squares is
A=l•w
(Area equals length times width)

The equation for triangles is
A=(1/2)b•h
(Area equals one half times bass times height)

What is the area of triangle UVW if the area of triangle RST is 36 cm and the scale

weeeeeb [17]

Answer:

225 cm²

Step-by-step explanation:

The ratio of areas is the square of the scale factor.

area UVW = (5/2)²·area RST = (25/4)(36 cm²) = 225 cm²

Ryan played in 3 basketball games. He scored 18 points in the first game and 12 points in the second game. If he scored 42 point

stealth61 [152]

The correct answer for this very hard equation would happen to be 12 because 18+12 happens to equal 30 and 42-30 just so happens to equal 12
