Dilation is either : enlargement or shirking.

Simply you multiply the ordered pair times the dilation vector (Origin-Centered) 

D.F = dilation factor;


d.f  = 5

C' = d.fC

when you multiply a constant times an ordered pair , it multiples into each of the pair.


C' = 5 ( -5 , 1 ) = ( -25, 5 ) 

In case you were asked for A' , B' (test yourself before checking) 



A' = 5 (-4,3) = ( -20 , 15)

B' = 5 ( 2, 3 ) = ( 10, 15) 

Dividing the dilated by the original pair results in the dilation factor

A'/A =  (-20/15)/(-4,3) = 5(-4,3)/(-4,3) = 5

A bucket contains 40 red balls, 25 black balls, and 35 white balls. Two balls are drawn at random. What is the probability that
Lyrx [107]

Answer:

Probability = \frac{1}{5} or Probability = 0.2

Step-by-step explanation:

Given

Black = 25

White = 35

Red = 40

Required

Determine the probability of selecting Black and Red

First, we need to calculate the number of red and black balls

The probability is calculated as thus:

Probability = P(Black\ and \ Red) \ or\ P(Red\ and \ Black)

Convert to mathematical expressions

Probability = [P(Black) *P(Red)] + [P(Red) *P(Black)]

Solve for each probaility;

P(Black) = \frac{Black}{Total} = \frac{25}{100}

P(Red) = \frac{Red}{Total} = \frac{40}{100}

So, we have:

Probability = [P(Black) *P(Red)] + [P(Red) *P(Black)]Probability = [\frac{25}{100} *\frac{40}{100}] + [\frac{40}{100} *\frac{25}{100}]

Probability = [\frac{1000}{10000}] + [\frac{1000}{10000}]

Probability = [\frac{1}{10}] + [\frac{1}{10}]

Probability = \frac{1+1}{10}

Probability = \frac{2}{10}

Probability = \frac{1}{5}

or

Probability = 0.2
