Answer:
a) The graph of the probability density function for flight time is shown below.
b) 1/2
c) 0
d) 130 minutes
Step-by-step explanation:
Let's deal with the flight times in minutes instead of hours, and let T be the random variable that represents the flight time. T is uniformly distributed between 120 minutes and 140 minutes. The probability density function for T is given by
for t in [120, 140]
a) The graph of the probability density function for flight time is shown below.
Delta Airlines quotes a flight time of 125 minutes for its flights from Cincinnati to Tampa.
b) The probability that the flight will be no more than 5 minutes late is given by
c) The probability that the flight will be more than 10 minutes late is given by
because the probability density function is zero for t outside of [120, 140]
d) The expected flight time is given by
minutes
<u>Answer:</u>
Below!
<u>Step-by-step explanation:</u>
<u>We can solve this with the help of equations.</u>
- 5 + 2x = 2x + 6
- => -2x + 2x = -5 + 6
- => 0 ≠ 1
<u>Since we are getting 0 ≠ 1 as our result, the problem has </u><u>no solution.</u>
Hoped this helped.

Step-by-step explanation:
Simplify :
x4−6x3+2x−7+7x3−x+5x2+2−x4
x4−6x3+2x−7+7x3−x+5x2+2−x4
Rearranging and collecting the like terms, we get:
=(x4−x4)+(−6x3+7x3)+5x2+(2x−x)+(−7+2)
=(1−1)x4+(−6+7)x3+5x2+(2−1)x+(−7+2)
=(1)x3+5x2+(1)x−7+2
=x3+5x2+x−5
Answer:
