Drag each statement to the correct location.

VMariaS [17]

Answer:

$(a)\ 222_{10} = DE_{16}$ --- True

$(b)\ D7_{16} = 11010011_2$ --- False

$(c)\ 13_{16} = 19_{10}$ --- True

Explanation:

Required

Determine if the statements are true or not.

$(a)\ 222_{10} = DE_{16}$

To do this, we convert DE from base 16 to base 10 using product rule.

So, we have:

$DE_{16} = D * 16^1 + E * 16^0$

In hexadecimal.

$D =13 \\E = 14$

So, we have:

$DE_{16} = 13 * 16^1 + 14 * 16^0$

$DE_{16} = 222_{10}$

Hence:

(a) is true

$(b)\ D7_{16} = 11010011_2$

First, convert D7 to base 10 using product rule

$D7_{16} = D * 16^1 + 7 * 16^0$

$D = 13$

So, we have:

$D7_{16} = 13 * 16^1 + 7 * 16^0$

$D7_{16} = 215_{10}$

Next convert 215 to base 2, using division rule

$215 / 2 = 107 R 1$

$107/2 =53 R 1$

$53/2 =26 R1$

$26/2 = 13 R 0$

$13/2 = 6 R 1$

$6/2 = 3 R 0$

$3/2 = 1 R 1$

$1/2 = 0 R1$

Write the remainders from bottom to top.

$D7_{16} = 11010111_2$

<em>Hence (b) is false</em>

$(c)\ 13_{16} = 19_{10}$

Convert 13 to base 10 using product rule

$13_{16} = 1 * 16^1 + 3 * 16^0$

$13_{16} = 19$

Hence; (c) is true

Write a function that takes as input a single integer parameter n and computes the nth Fibonacci Sequence number. The Fibonacci

RSB [31]

Answer:

Following are the code to this question:

def Fibonacci(n):#defining a method Fibonacci that accept a parameter

a = 1#defining a variable a that holds a value 1

b = 1#defining a variable b that holds a value 1

if n <= 0:# Use if to check n value

print("invalid number")#print message

elif n == 2:#defining elif that check n equal to 2

return 1#return 1

else:#defining else block

print(a)#print value of a

print(b)#print value of b

for i in range(2,n):#defining for loop to calculate series

s = a + b# add value in s variable

a = b # interchange value

b = s# hold s value

print(s)#print s value

Fibonacci(10)#calling method

Output:

1

2

3

5

8

13

21

34

55

Explanation:

In the above-given program code, a method "Fibonacci" is defined, which holds a value "n" in its parameter, and inside the method two-variable "a and b" is defined, that holds a value "1".

In the next step, if a block is defined that checks n value is less than equal to 0, it will print "invalid number" as a message.
In the elif, it checks n value is equal to 2 it will return a value that is 1.
In the else block, it will calculate the Fibonacci series and print its value.

Why did hockey champion Haley wickenheiser feel angry after the Bach said the IOC would make a decision in the next month?

aliina [53]

Haley wickenheiser felt angry after the Bach said the IOC would make a decision in the next month as the IOC says the games will be held no later than summer 2021 but they will still be called the 2020 Tokyo Olympics.

Explanation:

The Tokyo Olympics were postponed until 2021 on Tuesday, ending weeks of speculation that the games could not go ahead as scheduled because of the coronavirus pandemic.
The International Olympic Committee made the decision after speaking with Japanese Prime Minister Shinzo Abe and local organizers.
The IOC said the games will be held not later than summer 2021 but they will still be called the 2020 Tokyo Olympics.
“President Bach said he will agree ‘100%,’ and we agreed to hold the Tokyo Olympics and Paralympics in the summer of 2021 at the latest,” Abe said, saying holding the games next year would be “proof of a victory by human beings against the coronavirus infections.”
The decision came only a few hours after local organizers said the torch relay would start as planned on Thursday.
