Use the following cell phone airport data speeds​ (Mbps) from a particular network. Find P10. 0.1 0.1 0.3 0.3 0.3 0.4 0.4 0.4 0.
sasho [114]

Answer:

P_{10} =0.1

Explanation:

Given

0.1, 0.1, 0.3, 0.3, 0.3, 0.4, 0.4, 0.4, 0.6, 0.7, 0.7, 0.7, 0.8, 0.8

Required

Determine P_{10}

P_{10} implies 10th percentile and this is calculated as thus

P_{10} = \frac{10(n+1)}{100}

Where n is the number of data; n = 14

P_{10} = \frac{10(n+1)}{100}

Substitute 14 for n

P_{10} = \frac{10(14+1)}{100}

P_{10} = \frac{10(15)}{100}

Open the bracket

P_{10} = \frac{10 * 15}{100}

P_{10} = \frac{150}{100}

P_{10} = 1.5th\ item

This means that the 1.5th item is P_{10}

And this falls between the 1st and 2nd item and is calculated as thus;

P_{10} = 1.5th\ item

Express 1.5 as 1 + 0.5

P_{10} = (1 +0.5)\ th\ item

P_{10} = 1^{st}\ item +0.5(2^{nd} - 1^{st}) item

From the given data; 1st\ item = 0.1 and 2nd\ item = 0.1

P_{10} = 1^{st}\ item +0.5(2^{nd} - 1^{st}) item becomes

P_{10} =0.1 +0.5(0.1 - 0.1)

P_{10} =0.1 +0.5(0)

P_{10} =0.1 +0

P_{10} =0.1

write a function that takes a string as parameter, return true if it’s a valid variable name, false otherwise. You can use keywo
never [62]

Answer:

The solution code is written in Python 3:

  1. import keyword  
  2. def checkValidVariable(string):
  3.    if(not keyword.iskeyword(string)):
  4.        return True  
  5.    else:
  6.        return False  
  7. print(checkValidVariable("ABC"))
  8. print(checkValidVariable("assert"))

Explanation:

Firstly, we need to import keyword module so that we can use its iskeyword method to check if a string is registered as Python keyword (Line 1).

Next, we create a function checkValidVariable that takes one input string (Line 3). Within the function body, we use iskeyword method to check if the input string is keyword. Please note the "not" operator is used here. So, if iskeyword return True, the True value will be turned to False by the "not" operator or vice versa (Line 4-5).

We test the function by passing two input string (Line 9-10) and we shall get the sample output as follows:

True

False

alexira [117]

Answer:

In Python:

low = int(input("Low: "))

high = int(input("High: "))

if low >= 1000000000 or high >=1000000000:

   print("Out of range")

else:

   mylist = []

   for num in range(low,high+1):

       flag = False

       if num > 1:

           for i in range(2, num):

               if (num % i) == 0:

                   flag = True

                   break

       if not flag:

           mylist.append(num)

           print(num, end = " ")

   print()

   print("The twin primes are: ",end="")

   count = 0

   for i in range(1,len(mylist)):

       if mylist[i] - mylist[i-1] == 2:

           print(str(mylist[i])+" & "+str(mylist[i-1]),end=", ")

           count+=1

   print()

   print("There are "+str(count)+" twin primes")
