Nick has designed a diamond shaped kite as shown below. The measures of some sides of the kite are marked in the figure. Find th
Zepler [3.9K]

Answer:

<h2>x = 3.499 in</h2>

Step-by-step explanation:

       In a kite, the diagonals are perpendicular. Hence \Delta DOC is a right angled triangle.

       DC=7\text{ }in,\text{ }OC=5\text{ }in

From Pythagoras theorem, since \Delta DOC is a right angled triangle, DO^{2}+OC^{2}=DC^{2}.

      Area of \Delta DOC = \frac{1}{2}\times base\times height

=\frac{1}{2}\times DO\times OC=\frac{1}{2}\times OP\times DC\\(2\sqrt{6})\times(5)=(7)\times(OP)\\OP=3.499\text{ }in

From diagram OP=x

∴ x=3.499\text{ }in

Kobotan [32]

Answer:

Probability of getting at least 9 out of 18 correctly is 0.0043

Step-by-step explanation:

We have

n = 18

p = 1/5 for correct answer

q = 4/5 for wrong answer

P( 9 \leq X \leq 18) = 1 - P(0 \leq X\leq 8)

                       = 1 -  0.9957

                         =0.0043
