If a ray divides an angle into two complementary angles, then the original angle is not a right angle. True or false
1 answer:
The given statement " If a ray divides an angle into two complementary angles, then the original angle is not a right angle" is false.
As, Complementary angles are those in which sum of two angles add up to 90 degrees.
Now, let us consider two angles made by the ray is 'x' and 'y'. According to the question, the ray divides an angle into two complementary angles which means
In this case since the two angles formed after being divided by ray are complementary it means they add up to 90 degrees. And hence, the original angle should be a right angle.
Therefore, it is false to say that the original angle is not a right angle.

Answer:
0.67% probability he will have to shut down after this month
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
On average sells 8.9 machines per month.
So
Using the Poisson distribution, what is the probability he will have to shut down after this month
If he sells less than 3 machines.
0.67% probability he will have to shut down after this month
