The scheduled arrival time for a daily flight from Boston to New York is 9:30 am. Historical data show that the arrival time fol
Galina-37 [17]

Answer:

Step-by-step explanation:

Let x be a random variable representing the flight arrival time from Boston to New York.

For a uniform probability distribution, the notation is

X U(a, b) where a is the lowest value of x and b is the lowest value of x

The probability density function, f(x) = 1/(b - a)

Mean, µ = (a + b)/2

Standard deviation, σ = √(b - a)²/12

From the information given, the time difference in minutes is 9:57 - 9:07 = 50 minutes. Therefore,

a = 0

b = 50

µ = (0 + 50)/2 = 25

σ = √(50 - 0)²/12 = 14.43

b) converting to minutes, it is 9:30 - 9:07 = 23 minutes

the probability that a flight arrives late(later than 9:30 am) is expressed as P(x > 23)

f(x) = 1/(50) = 0.02

P(x > 23) = (50 - 23)0.02 = 0.54

Sara can type 90 words in 4 minutes. About how many words would you expect her to type in 10 minutes at this rate?
Talja [164]

Answer:

She can type 225 words in 10 minutes

Step-by-step explanation:

We can find the rate by dividing the number of words by the time

90 words/ 4 minutes

22.5 words per minute

Now  to find the number of words in 10 minutes, multiply the rate times the time

22.5 * 10 = 225

She can type 225 words in 10 minutes
