A circle has the equation x2+ y2 = 9. What is the length of the radius?

Zarrin [17]

Answer:

The center is (0,0) and the radius is 3

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2+(y-k)^2 = r^2

Where (h,k) is the center and r is the radius

(x-0)^2+(y-0)^2 = 3^2

The center is (0,0) and the radius is 3

GREYUIT [131]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Given:

$N= 177\\\\a=46\\\\b=52\\\\c=36\\\\d=43$

$\to \chi _{1}^{2}=\frac{N(ad-bc)^{2}}{(a+c)(b+d)(a+b)(c+d)}$

$=\frac{177((46\times 43)-(52 \times 36))^{2}}{(98)(79)(82)(95)}\\\\=\frac{177((1978)-(1872))^{2}}{60310180}\\\\=\frac{177(106)^{2}}{60310180}\\\\=\frac{177(11236)}{60310180}\\\\=\frac{1988772}{60310180}\\\\= 0.032976$

P-value= $CHIDIST(0.032976,1) = 0.86.$

thus, the surgical-medical patients and Medicare are dependent.

nataly862011 [7]

Answer:

$L=\frac{15}{16}\ yd$

Step-by-step explanation:

<u><em>The correct question is</em></u>

Devon needs a wood board with an area of 5/16 square yard to complete a project. If the wood board is 1/3 yard wide, how long must the board be?

we know that

The area of a rectangle is equal to

$A=LW$

where

L is the length

W is the width

we have

$A=\frac{5}{16}\ yd^2\\\\W=\frac{1}{3}\ yd$

substitute

$\frac{5}{16}=L(\frac{1}{3})$

solve for L

$L=\frac{5}{16}(3)$

$L=\frac{15}{16}\ yd$
