Answer:36π
Step-by-step explanation:
Diameter=12
Radius=diameter/2
Radius=12/2
Radius=6
Area of circle =π x Radius x Radius
Area of circle=π x 6 x 6
Area of circle=36π
Answer:
The second one
Step-by-step explanation:
Because there are more people
The expressions equivalent to the original expression of
-2.7 - 16.4 would be
B. -16.4 + (-2.7)
D. -2.7 + (-16.4)
The answer would be <u>16</u>. Neither 24, 28, or 36 can multiply by a whole number to equal 64, and 16 cannot be multiplied by a whole number to equal those values.

Answer:
0.4968 = 49.68% probability that the repair time takes between 2 to 4 hours
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which is the decay parameter.
The probability that x is lower or equal to a is given by:
Which has the following solution:
The probability of finding a value higher than x is:
Average repair time of 2 hours
This means that
What is the probability that the repair time takes between 2 to 4 hours
More than 2:
Less than 4:
Between two and four:
0.4968 = 49.68% probability that the repair time takes between 2 to 4 hours
