An airline tracks data on its flight arrivals. Over the past six months, 25 flights on one route arrived early, 150 arrived on t

lions [1.4K]

Answer: a) 0.0625,0.375,0.1125,0.075 respectively.

b) Yes, they are mutually exclusive

c) 0.4375.

Step-by-step explanation:

Since we have given that

Number of flights on one route arrived early = 25

Number of flights arrived on time = 150

Number of flights were late = 45

Number of flights were cancelled = 30

Total number = 25+150+150+45+30 = 400

We need to find the probability that a flight is early is given by

$\dfrac{25}{400}\\\\=0.0625$

Probability that a flight is on time is given by

$\dfrac{150}{400}=0.375$

Probability that a flight is late is given by

$\dfrac{45}{400}=0.1125$

Probability that a flight is cancelled is given by

$\dfrac{30}{400}=0.075$

They are mutually exclusive as they have no dependence.

Probability that a flight is either early or on time is given by

$\dfrac{25}{400}+\dfrac{150}{400}\\\\=\dfrac{175}{400}\\\\=0.4375$

Hence, a) 0.0625,0.375,0.1125,0.075 respectively.

b) Yes, they are mutually exclusive

c) 0.4375.

Describe a real world situation between the area of a rectangle and its width, as the width varies and the length stays the same

raketka [301]

Area of rectangle = length x width If length is constant, say c and width is variable, say x Area of rectangle = y = cx This means Area will vary linearly with width and will represent a line with slope... hope I helped
