1 answer:

7 0

Answer: 11,499.0145103 ft ( $60.5^{2}\pi$ )

Step-by-step explanation:

$a = \pi r^{2}$
121 = d, d = rx2
121/2 = 60.5
$60.5^{2}$ = 3660.25
3660.25 x $\pi$ = 11,499.0145103

The point A (-5, -2) is reflected over the line y = -1, and then is reflected over the line x = 3. What are the coordinates of A

dmitriy555 [2]

When A is reflected over y=-1, -1+(-1-(-2))=0, it lands on (-5, 0), when it is then reflected over x=3, 3+(3-(-5))=11, it lands on (11,0)
If you can't visualize it, draw a graph.

An urn contains n balls, one of which one is special. If k of these balls are withdrawn one at a time, with each selection being

Aleksandr [31]

Using it's concept, it is found that the probability that the special ball is chosen is given by:

$p = \frac{1}{C_{n,k}}$

<h3>What is a probability?</h3>

A probability is given by the number of desired outcomes divided by the number of total outcomes.

The total number of outcomes is given by the combination of k balls from the set of n balls, given by:

$C_{n,k} = \frac{n!}{k!(n - k)!}$

One ball is special, hence the probability the special ball is chosen is given by:

$p = \frac{1}{C_{n,k}}$
