Answer: 0.5
Step-by-step explanation:
Binomial distribution
, where P(x) is the probability of getting success inn x trials , n is the number of trails and p is the probability of getting success in each trial.
Given : Sarah times her morning commute such that there is an equal likelihood that she will arrive early or late to work on any given day.
Then , the probability that Sarah is late on particular day = 
Then , the probability that Sarah will arrive late to work no more than twice during a five day workweek :-
Hence, the required probability : 0.5
Answer:
245°
Step-by-step explanation:
the bearing is 180° + 65° = 245°
Sum means add so 23 plus 54 is 77

Answer: I got C.
Step-by-step explanation: I squared both 3.9 and 9.7 which gave me 109.3. Then, I square rooted it and got 10.45 which rounds to 10.5. Hopefully, this is right.
Answer:
10 units
Step-by-step explanation:
To find the length we can use the formula
d = sqrt( (y2-y1)^2 + (x2-x1)^2)
We have the two points (-5,5) and (3,-1)
d = sqrt( (-1-5)^2 + (3--5)^2)
d = sqrt( (-6)^2 + (3+5)^2)
d = sqrt( (-6)^2 + (8)^2)
d = sqrt( 36 + 64)
d = sqrt(100)
d = 10
