Here are two coins in a box. one coin is fair, the other has heads on both sides. you draw one coin at random, toss it, and it l

Heads will come up when you draw the two headed coin 1/2 This 1/2 is for the draw. You have certainty of getting heads from this coin.

On a fair coin, probability of drawing the coin is 1/2
The probability of getting heads is 1/2
The probability is 1/2 * 1/2 = 1/4 with this coin

The total probability = 1/4 + 1/2 = 3/4 or 0.75 of getting heads.
Therefore the probability of drawing the 2 headed coin is 1/2 // 3/4
0.5 / 0.75 = 0.666666

Two figures are shown. EFJL is dialation of ABIK AB has a length of 12 and EF has a length of 3
Dimas [21]

The scale factor of dilation from AB to EF is 0.25

<h3>How to determine the scale factor of dilation?</h3>

The given parameters are:

  • EFJL is dilation of ABIK
  • AB has a length of 12
  • EF has a length of 3

From the above parameters, side lengths AB and EF are corresponding sides

This means that:

The scale factor of dilation (k) is

k = AB/EF

So, we have

k = 3/12

Evaluate

k = 0.25

Hence, the scale factor of dilation from AB to EF is 0.25

Carlos is a boat dealer who bought a sailor for 11,400 and sold it for 12,711 what percent was his markup on a boat
dangina [55]
So we have 11400 +11400×x=12711
this represents the original price plus some percentage of the original price is equal to the new price. now all we need to do is solve for x
so 11400+11400x=12711
subtract 11400 from each side
11400x=1311 now divide both sides by 11400
x=.115 or about 12%
we can. check by finding 12% of the original price.
11400×.12=1368
now add to 11400
11400+1368=12768 so we are a bit over. this is because it is actually 11.5% just depends on how accurate your answer needs to be

Roll a dice if the dice shows 6 tick the box marked yes.
maksim [4K]
That is a strangely worded question... but I think you're asking how many people said they got a 6 but did not.

So, a dice that has 6 sides has a 1/6 chance of Landing on a 6. so 1/6 of 360 should be that 60 people got a 6. Therefore 119-60 = 59.

The proportion is 59/360 that lied
