This is python:

#Write a function called count_positive_evens. This function
#should take as input a list of integers, and return as
#output a single integer. The number the function returns
#should be the count of numbers from the list that were both
#positive and even.
#
#For example:
#
# count_positive_evens([5, 7, 9, 8, -1, -2, -3]) -> 1
# count_positive_evens([2, 4, 6, 8, 10, 12, 15]) -> 6
# count_positive_evens([-2, -4, -6, -8, -10, 1]) -> 0
#
#0 should be not counted as a positive even number.
#
#Hint: Remember, even numbers are numbers that have a
#remainder of 0 when divided by 2.


#Write your function here!


#The lines below will test your code. Feel free to modify
#them. If your code is working properly, these will print
#the same output as shown above in the examples.
print(count_positive_evens([5, 7, 9, 8, -1, -2, -3]))
print(count_positive_evens([2, 4, 6, 8, 10, 12, 15]))
print(count_positive_evens([-2, -4, -6, -8, -10, 1]))

PYTHON: Write a function insertInOrder that takes in a list and a number. This function should assume that the list is already in ascending order. The function should insert the number into the correct position of the list so that the list stays in ascending order. It should modify the list, not build a new list. It does not need to return the list, because it is modifying it.   Hint: Use a whlie loop and list methods lst = [1,3,5,7]...

write a javascript function called cal_modes that will take a List of numbers or strings as input and returns a List of the most frequent values. If there's only one most-frequent value, it returns a single-element List. example cal_modes([3,4,5,5]) should return [5] cal_modes([8.9, 1, 1]) should return [1] cal_modes([2.5, -2, -2, 2.5]) should return [2.5] cal_modes([3,3,4,4]) should return [3,4] cal_modes([3,4,5]) should return [3,4,5], because all occur with equal frequency cal_modes(["hi", "what", "where", "hi"]) should return ["hi”]

The function has as arguments a list called ?????? and a list call center. • List ?????? contains lists that represent points. o For example, if ?????? = [[4,2], [3,2], [6,1]], the list [4,2] represents the point with coordinate ? at 4 and y coordinate at 2, and so on for the other lists. Assume that all lists within points contain two numbers (that is, they have x, y coordinates). • List ??????...
