Answer:
The probability that none of the 10 calls result in a reservation is 0.60%. In turn, the probability that at least one call results in a reservation being made is 99.40%.
Step-by-step explanation:
Since approximately 40% of the calls to an airline reservation phone line result in a reservation being made, supposing an operator handles 10 calls, to determine what is the probability that none of the 10 calls result in a reservation, and what is the probability that at least one call results in a reservation being made, the following calculations must be performed:
0.6 ^ 10 = X
0.006 = X
0.006 x 100 = 0.60%
Therefore, the probability that none of the 10 calls result in a reservation is 0.60%.
100 - 0.60 = 99.40
In turn, the probability that at least one call results in a reservation being made is 99.40%.
Answer:
-7.2
Step-by-step explanation:
2.4 + -7.2 = -4.8
-4.8 + (-7.2 *2) = 9.6
9.6 + (-7.2 *3) = -19.2
Answer and Step-by-step explanation:
angle 7 = 70 by the vertical angles theorem.
angle 7 = 50 by the corresponding angles theorem
angle 3 = 80 by the consecutive angles theorem (same side interior angles theorem)
angle 2 = 105 by the alternate interior angles theorem.
Because all angles in a triangle add up to 180° 100°+30°=130° 180°-130°=50°
I hope this is helpful and correct♡♡~~Chyna
