Answer:
(-2.5, 3)
Step-by-step explanation:
91 can go into 357 3 times
Answer:
0.298
Step-by-step explanation:
in this case we have an exponential distribution:
1 - e ^ (- x / y)
where x and y corresponds to the times we find in the exercise.
Now follows memoryless property.
P (More than 23 additional minutes | 20 minutes passed)
P = P (More than 23 minutes)
P = 1 - P (Less than or equal to 23 minutes)
P = 1 - (1 - e ^ (- 23/19))
P = 0.298
Therefore the probability is 29.8%
35 + 8w = 179.40
8w = 179.40 - 35
8w = 144.40
w = 144.40/8
w = 18.05 per week
