B. a map that shows the topography of Haiti
C. a link to a Web site that shows pictures of coral reefs
D. a chart listing results of a scientific study about ultraviolet radiation
Visual is something that an individual can see with his/her two eyes. Where as ultraviolet Ultraviolet is electromagnetic emission with a wavelength from 10 nm to 400 nm, lower than that of apparent light but greater than X-rays. UV radiation is already in sunlight composing about 10% of the entire light amount of the Sun.
B. Use the thesaurus to replace the misspelled word with the correct spelling.
C. Use the spell checker to correct all misspelled words.
D. Use "Find" to find each place she misspelled a word.
Answer:
from functools import reduce
def mean(mylist):
score = reduce(lambda x,y: x + y, mylist)/ len(mylist)
return score
def median(mylist):
sorted(mylist)
list_len = len(mylist) % 2
i = round(len(mylist)/2)
x = len(mylist)//2
if list_len == 0:
median = (mylist[x] + mylist[x+1]) / 2
else:
median = mylist[i]
return median
def mode(mylist):
unique = set(mylist)
unique = list(unique)
collector = [mylist.count(key) for key in unique]
maxi = max(collector)
loc = collector.index(maxi)
return unique[loc]
def main():
scores = input( 'Enter list of numbers: ').split(",")
scores = [int(score) for score in scores]
operation = input('Enter operation: ')
operator = ['mean', 'median', 'mode']
for x in iter(list, 0):
if operation in operator:
break
print("Invalid operation: ")
operation = input('Enter operation')
index_loc = operator.index(operation)
if index_loc == 0:
return mean(scores)
elif index_loc == 1:
return median(scores)
#return np.median(scores) can be used of the defined function
elif index_loc == 2:
#return stats.mode(scores)[0] can be used of the defined function
return mode(scores)
print( main( ) )
Explanation:
The main python function calls conditionally three statistical functions namely mean, median and mode. It prompts for user input for a list of integer numbers and a function name name to return the corresponding result.
Answer:
Radio Frequency Identification (RFID)
Explanation:
A Radio Frequency Identification uses a tag that is made up of of a tiny radio receiver and transmitter, that transmits digital data when it receives an electromagnetic pulse from a nearby RFID reader device. This makes it possible to track an item, animals, or even a person by placing a RFID tag on it, and then monitor the tagged object over a network.
