Question 12 PYTHON:

Write a function named first_last that takes a single parameter, string_list (a list of strings). The
function first_last should return a list of the strings in string_list that are not empty and that begin
and end with the same letter.

For example, the following would be correct input and output for the function first_last.

response = ['to', 'that', 'I', 'say', '', 'hurrah']
print(first_last(response))
['that', 'I', 'hurrah']

Question 13 (20 points)

Write a function named number_luck. The function number_luck takes two parameters:

1. lucky, a list of lucky numbers between 2 and 12, inclusive
2. unlucky, a list of unlucky numbers between 2 and 12, inclusive

Every number is either lucky, unlucky or boring (neither lucky nor unlucky).

The function number_luck should

1. ask the user for a number in the range 2 to 12 (you may assume that the user provides valid
input)
2. print a message echoing the user’s number and stating whether it is lucky, unlucky or boring
3. return an integer that is the user’s number

For example, the following would be correct input and output.

>>> a_num = number_luck([7, 11], [2, 3, 12])
Give me a number from 2 to 12: 7
7 is lucky. You win!
>>> print(a_num)
7

The horizontal and vertical components of the initial velocity of a football are 20m/s and 30 m/s respectively. Assume that after rising some height, the football returns back to the ground level.

1) what is the speed of the football at 3s after launch?

2) to what maximum height does the football rise?

3)What horizontal distance does the football travel during its flight?

Please show full explaination and steps for answer.

A randomly selected list of holiday food items was generated. Thirty King Kong stores were surveyed as to what the cost of the list of items would cost. The mean and standard deviation is recorded in the table below. Fifty Saves Alot stores were surveyed in a similar manner and the mean and the standard deviation was recorded below. Test whether the King Kong mean amount spent is less than the Saves Alot amount spent. a = 0.01.

I need to calculate the initcial concentrations of I- and S2O8^2- then use that to calculate the reaction rate M/sec and the k value.

A vertical summit parabolic curve has vertical offset of 0.375 m. from the curve to the grade tangent at Station 10 + 050. The curve has a slope of +4% and -2% grades intersecting at the P.I. The offset distance of the curve at P.I. is equal to 1.5m. If the stationing of the P.C. is at 10 + 000.

Compute the (a) required length of curve (b) horizontal distance of the vertical curve turning point from the point of intersection of the grades. (c) elevation of the vertical curve turning point if the elevation of P.T. is 86.42 m

(C++)Problem #1: Coin Tossing Simulation: Write a program that simulates coin tossing. Let the program prompt the user to enter the number of tosses N and count the number of times each side of the coin appears. Print the results. The program should call a separate function flip() that takes no arguments and returns 0 for tails and 1 for heads. The program should produce different results for each run.

Sample Input / Output

Enter the number of tosses N: 1000

The total number of Heads is: 495

The total number of Tails is: 505
