n a random sample of seven people, the mean driving distance to work was 19.5 miles and the standard deviation was 4.3 miles. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 95% confidence interval for the population mean mu. Interpret the results

A goose is flying south for the winter at a constant speed. Keep in mind that one mile is 1.61 km , and one pound is 454 g . The goose has a mass of 16.4 lb (pounds) and is flying at 7.30 miles/h (miles per hour). What is the kinetic energy of the goose in joules?

The number of miles a motorcycle, X, will travel on one gallon of gasoline is modeled by a normal distribution with mean 44 and standard deviation 5. If Mike starts a journey with one gallon of gasoline in the motorcycle, find the probability that, without refueling, he can travel more than 50 miles.

You have been recording how many miles you get per tank of gas, and you have found a mean of 297 and a standard deviation of 23. Use this information to answer the following question.
What is the probability you will get 300 miles out of a tank of gas?

While traveling home for the holiday, you wondered how much time you'd save if you drove faster. The distance home is 120 miles, and you decided to compare driving 55 mph versus 70 mph. You also wondered if driving faster around town really saves you that much time. The around-town distance you chose was 5 miles, using speeds of 25 and 35 mph. Of course, you decided that no amount of times savings is worth the risk to yourself or others, but you still wanted to find the answer.
Create two functions to help calculate the travel time in hours, minutes and seconds and to display the results.
# Calculate travel time in minutes given the distance in miles and the speed in mph calc_travel_time ( distance, speed ) # Output the travel time hours, minutes and seconds given distance and speed print_travel_time ( distance, speed )
Your Python solution must include the following:
Tip:
Expected output:
To travel 120 miles at 55 MPH will take 2 hr, 10 min and 55 sec To travel 120 miles at 70 MPH will take 1 hr, 42 min and 51 sec To travel 5 miles at 25 MPH will take 0 hr, 12 min and 0 sec To travel 5 miles at 35 MPH will take 0 hr, 8 min and 34 sec

in BASIC language, i need to make function smallMiles(size) display the smallest number in the MilesDriven array . here is my code so far:
size =1
Dim Monthname$(size)
Dim MilesDriven(size)
do
print "Enter your choice from this menu."
print "Enter 'P' to enter miles and month,OR"
print "Enter 'S' to search for month. OR,"
print "Enter 'M to search month with smallest miles. OR,"
print "Enter 'L' to search for month with largest miles. OR,"
print "Enter 'E' to exit."
input choice$
select case (choice$)
case "P","p"
res= collectData(size)
case "S","s"
res = search(size)
case "M","m"
res = smallMiles(size)
case "L","l"
res = largeMiles(size)
case "E","e"
print "Have a nice day.Goodbye."
case else
print "Invalid choice, please try again"
print
end select
loop until (choice$ = "E" or choice$ = "e" )
function collectData(size)
for position= 0 to size
print "Enter miles."
input MilesDriven(position)
print "Enter month."
input Monthname$(position)
next
end function
function search(size)
print "Enter month."
input month$
for position = 0 to size
if(month$ = Monthname$(position))then
print "The month is: ";Monthname$(position)
print "The number of miles driven is: ";MilesDriven(position)
exit for
end if
next
end function
function smallMiles(size)
print "Enter month."
input month$
for position = 0 to size
smallest = MilesDriven(position)
if (month$ = Monthname$(position))then
if (MilesDriven(position) < smallest )then
smallest = MilesDriven(position)
end if
print "The month with smallest miles driven is:
";Monthname$(position)
print "The smallest miles driven is: ";smallest
exit for
end if
next
end function
