Answer:
0.025
Step-by-step explanation:
Given that the arrival time of a professor to her office is uniformly distributed in the interval between 8 and 9 A.M.
If the professor did not arrive till 8.20 he will arrive between 8.21 and 8.40
Hence probability for arriving after 8.20 is 1/40
Prob he arrives at exactly 8.21 is 1/60
To find the probability that professor will arrive in the next minute given that she has not arrived by 8: 20.
= Prob that the professor arrives at 8.21/Prob he has not arrived by 8.20
This is conditional probability and hence
= 
The solution is (6, -8) (solved by graphing with Desmos.com/calculator)
-DIVIDE- the area of a triangle by the -BASE-
, and -MULTIPLY- the result by -2-
Explanation:
Thats because the formula for the area of a triangle is 1/2 x base x height OR (much not confusing formula) BASE x HEIGHT divided by 2
Mark me brainliest tysm! Have a nice day
y=3x, y=(2/7)x,-0.5=y are all on direct the other ones are on the other side i just did the question they correct. :)
