=10
Started at first floor
went up 18 floors, so now we are at 1+18 or 19th floor
then cam down 11 floors, so now we are at 19-11 or 8th floor
then went up 16, so now at 16+8 or 24th floor
it stopped at 24th floor
Answer:
So, the probability is P=0.018.
Step-by-step explanation:
We know that Pedro drives the same route to work on Monday through Friday.
We know that there is a 55% chance that the light will be red.
We get that p=55%=0.55.
We conclude that the probability of not being a red light:
q=1-p=1-0.55=0.45.
We can calculate the probability that from Monday to Friday when Pedro goes to work there will be no red light, as follows:

So, the probability is P=0.018.
4/5*3/7=a
a=12/35
12/35 square units
Answer:
A=78
B=102
C=78
Step-by-step explanation:
A= a and 102 are on a straight line so they add up to 180. 180-102=78. The same goes for C
B= the vertical angle for 102, or the same thing with a and c, just flipped around
