Answer:
The answer to the question is 0.43. Let's explain why.
Step-by-step explanation:
A train arrives at the station at 15-minute intervals starting from 7:00 am which makes the train arrives at;
7:00
7:15
7:30
7:45
8:00
B train arrive at 12-minute intervals starting at 7:07 means B train arrives at;
7:07
7:19
7:31
7:43
7:55
Now, let's review the chances of a passenger arrives at the station any time between 7:00 am and 8:00 am
- If the passenger arrives between 7:00 - 7:07 the passenger will get into B train which gives us the
chance since an hour is 60 minutes and the passenger waited for 7 minutes. - If the passanger arrives between 7:07 - 7:15 passenger will get into A train which gives
chance. If we apply this to the time limits it goes by; - Between 7:15 - 7:19 passenger will go to B destination which gives
chance - Between 7:19 - 7:30 passenger will go to A destination means
chance - Between 7:30 - 7:43 passenger will go to B destination means
chance - Between 7:43 - 7:45 passenger will go to A destination which gives
chance - Between 7:45 - 7:55 passenger will go to B destination means
chance - An lastly between 7:55 - 8:00 passenger will go to A destination which gives us
chance
Now for passenger to go to A destination the total chances are:
= 0.43
Answer:
89 degrees
Step-by-step explanation:
The angle 1 is the same as angle 3.
Angle 2 is the same as angle 4.
The sum of these four angles is 360 degrees.
We have that:
Angle 2 = Angle 4 = 7x - 14
Angle 3 = Angle 1 = 5x + 14
Finding x:
Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360
2*(5x + 14) + 2*(7x - 14) = 360
10x + 28 + 14x - 28 = 360
24x = 360
x = 15
Angle 1:
5x + 14 = 5*15 + 14 = 89 degrees

Answer:
Step-by-step explanation:
Many calculators use "E" to signify "×10^( )". Thus ...
... 1.3E-2 = 1.3×10^(-2)
This number in scientific notation is equivalent to the standard form number ...
... 1.3×0.01 = 0.013
