A. if the return trip is the same then the bird traveled 40miles
b. the time of the trip is x hours + 6/x-4
When x = 6.4, y=117, therefore
15*6.4 + b = 117
b = 117 - 96 = 21
Confirm this value by checking (6.6, 120).
15*6.6 + 21 = 120 (Correct)
Answer: b = 21
As the function is
y = 10,000 + 350x , Here x is the number of months elapsed and y is the amount after x number of months.
This function is for the form
y = mx +b or y = b +mx
which is the form of a linear equation
So the given function is a linear function.
So a is true
a)The function is a linear function.
Also The function is increasing at a constant rate , So options C and E are also correct
So
A, C and E
Answer:

And replacing we got:

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714
Step-by-step explanation:
We define the random variable of interest as x " time it takes a barber to complete a haircuts" and we know that the distribution for X is given by:

And for this case we want to find the following probability:

We can find this probability using the complement rule and the cumulative distribution function given by:

Using this formula we got:

And replacing we got:

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714
