Answer:

The answer is

<h2>\sqrt{101}  \:  \:  \: or \:  \:  \: 10.05 \:  \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(4,-9) and (-6,-10)

The distance between them is

d =  \sqrt{ ({4 + 6})^{2}  + ( { - 9 + 10})^{2} }  \\  =  \sqrt{ {10}^{2} +  {1}^{2}  }  \\  =  \sqrt{100 + 1}  \:  \:  \\  =  \sqrt{101}  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  = 10.04987...

We have the final answer as

\sqrt{101}  \:  \:  \: or \:  \:  \: 10.05 \:  \:  \:  \: units

Hope this helps you

elizabeth has 8 socks in her drawer: 4 black socks, 2 white socks and 1 brown sock and 1 red sock. she chooses a sock at random
Debora [2.8K]

The probability that she picks two white socks is 0.0357

<h3>How to determine the probability?</h3>

The given parameters are:

Socks = 8

Black = 4

White = 2

Brown = 1

Red = 1

The probability of picking a white sock at first is:

P(White) = 2/8

Now, there are 7 socks left

The probability of picking a white sock next is

P(White) = 1/7

The required probability is:

P = 2/8 * 1/7

Evaluate

P = 0.0357

Hence, the probability that she picks two white socks is 0.0357
