4 Permutations 1. Let a "small block cipher be a function f which maps 8-bit plaintexts m E (0,1)8 to 8-bit ciphertexts c E (0,1

)8. However, function f must be 1-1 or otherwise it would be impossible to invert a block cipher, i.e. compute (using the block cipher key) the plaintext f(c) given ciphertext c. How many "small" block ciphers are there? students if each student must have a computer and computers cannot be shared? capital letters but with no repeated characters? 2. There are 10 computers and 5 students. In how many ways can computers be assigned to 3. Recall problem 1. How many 8-character passwords are there made of either lower-case or . How many 10-digit decimal strings are there in which there is no repeated digits? 5. How many 10-digit decimal strings are there in which there is no repeated digits and where 5" occurs before "6"? (By "before" I mean "anywhere before" and not "mmediately before", e.g. string (5,0, 1, 2, 3, 4, 7, 8, 9, 6) is included.) 6. How many 10-digit decimal strings are there in which there is no repeated digits and where "5" and "6" are next to each other?

Solve both equations and pls show work.. <br> I will mark brainliest
Alexxx [7]

Answer:

7. x = 4

8. x = 10

Step-by-step explanation:

7. The angles are equal to each other so you can do

40 = 12x - 8

48 = 12x

4 = x

8. The angles add up to be 180 degrees so you can combine them and set them equal to 180

6x + 12x = 180

18x = 180

x = 10

Given:
olga55 [171]

Answer:

Step-by-step explanation:

y = 1/3x + 6

y = 1/4x + 3

this is just a matter of substitution...subbing in one y for the other

y = 1/3x + 6.....so sub in 1/3x + 6 in for y, back into the second equation or u can work it the other way and sub in 1/4x + 3 in for y, back into the first equation....either way will work

1/3x + 6 = 1/4x + 3

1/3x - 1/4x = 3 - 6

4/12x - 3/12x = -3

1/12x = -3

x = -3 * 12

x = - 36

now sub that back into either of ur original equations to find y

y = 1/3x + 6

y = 1/3(-36) + 6

y = - 12 + 6

y = - 6

solution is : x = -36 and y = -6 or (-36,-6)

Pls help ASAP need help pls
AlexFokin [52]

Answer:

1.625

Step-by-step explanation:

First we need to find the mean of this data set

29+32+33+28+30+30+29+33=244

Then we divide 244 by the amount of numbers in the set

244/8=30.5

Then we need to find the deviation of each number

29 | 32 | 33 | 28 | 30 | 30 | 29 | 33

1.5 | 1.5 | 2.5 | 2.5 | 0.5 | 0.5 | 1.5 | 2.5

Then we take the mean from this set of data

1.5+1.5+2.5+2.5+0.5+0.5+1.5+2.5=13

Then divide

13/8=1.625

I hope this helps :)
