Answer:
The measure of the third angle is
Step-by-step explanation:
we know that
The sum of the interior angles in a triangle must be equal to 180 degrees
Let
x ---> the measure of the third angle in degrees
The linear equation that represent this situation is
solve for x
Answer:
probability that actual service time will be less than or equal to five minutes = P(X <= 5) = 1 - e-15(5/60) = 0.714 or 71.4%
Step-by-step explanation:
The identification of the average arrival rate of customers(v) and the average service rate(u) must be done in order to solve this kind of problem .
In this case, on average, 12 customers arrive each hour. On average, the service rate is 15 customers per hour.
The arrival rate follows the exponential distribution.
probability that actual service time will be less than or equal to 't' minutes P(X <= t) = 1 - e-u(t/60)
probability that actual service time will be less than or equal to five minutes = P(X <= 5) = 1 - e-15(5/60) = 0.714 or 71.4%
Correct option D) .
<u>Step-by-step explanation:</u>
Here we have , A prepaid phone card has a balance of $22.40 remaining. Given that it costs $0.035 per minute . We need to find an equation represents the number of minutes, m, you may talk using the card . Let's find out :
Total balance = $22.40
It costs $0.035 for one minute of call . Let's suppose that with balance $22.40 we can talk for m minutes . So equation will be :
⇒
⇒
⇒
Therefore , an equation represents the number of minutes, m, you may talk using the card is . Correct option D) .
