1. Check the tree diagram in the picture attached.
2. The blue segment represents "on time"
The red segment represents "not on time"
3. blue - blue - red represents the case 1st on time, 2nd on time, 3rd not on time.
the combined probability is 90/100*90/100*10/100=9/10*9/10*1/10=99/1000=0.099
4. Remark with a tree diagram we can tell anything asked about the probability of an experiment.
6.5 - 3 = 3.5
11 - 6.5 = 4.5
16.5 - 11 = 5.5
23 - 16.5 = 6.5
From this, you can see that the number being added is increasing by 1 each time.
Therefore, the pattern is adding 3.5, then 4.5, then 5.5, then 6.5, and so on.
X is 90°
A triangles angles add up to 180° so
180 - 47 - 90 = y
180 - 137 = y
y = 43°
Si you would subtract 6x from both sides so you would have 9y=1500-6x. Then you would divide both sides by 9 and get y=166.66-6/9x. The -6/9x can be reduced to -2/3x and that is your slope or your
rise/run and the only graph that show this is the second one
The answer should be (exact number- 93/10) (decimal form- 9.3) (mixed number- 9 3/10)
sorry if i’m incorrect
