Answer:
D
Step-by-step explanation:
first, you take the total and divide it by 3 since 3 is multiplied by x
when you divide -27 by 3 you get -9 and that is the answer.
-27/3=-9
x=-9
17.54% is the probability that 5 messages are received in 1 hour.
The chance that X reflects the number of successes of a random variable in a Poisson distribution is provided by the following formula:
P(X = x) = ( × ) ÷ x!
In where x is the number of successes, e is the Euler number, and u is the mean in the specified time frame.
In this case, the average message rate is 5 messages per hour.
The probability of receiving 5 texts in one hour.
Determine the value of P for x = 5 and u = 6.
P(X = x) = ( × ) ÷ 5!
P(X = x) = 21.0560 ÷ 5!
P(X = x) = 0.1754
There is a 17.54% chance that 5 messages will be received in 1 hour.

Answer:
X= 35 degrees
Step-by-step explanation:
Well, we know that 20+x+x=90 because angle ml is a 90 degree angle.
Then, we make an equation; 20+x+x=90
WE solve for x, by combining like terms, so it would now be 20+2x=90
We subtract 2 from both sides, making it 2x=70
Then divide both sides by 2 , making it x=35
