C/3-7=5.3 how do I do this?

13 + 3y= 37 solve for y

Nikitich [7]

Answer:

y = 8

Step-by-step explanation:

Step 1: Write out equation

13 + 3y = 37

Step 2: Subtract 13 on both sides

3y = 24

Step 3: Divide both sides by 3

y = 8

A hard-headed hacker is attempting to login into Larry’s Amazon account by guessing his password. The hacker does not give up un

monitta

Answer:

(a) $1.59\times10^{-8}$

(b) $3.30\times10^{-11}$

(c) $1.87\times10^{-11}$

(d) $4.58\times10^{-12}$

Step-by-step explanation:

The password is of 8 characters.

The hacker tries 1000 times to get the correct password.

(a)

There are 26 letters in the English Alphabet series.

The number of ways to create a password of 8 different lower-case letters are:

${^{26} P_8} = \frac{26!}{(26-8)!}= 62990928000$

The probability of selecting the correct password if 8 different lower-case letters are used is:

$P(Correct\ Password)=\frac{1000}{62990928000} = 1.59\times10^{-8}$

(b)

If both upper case and lower case letters are used, then there are 52 letters available to form a 8 characters password.

The number of ways to create a password of 8 different letters, some may be upper-case, and it is case sensitive is:

${^{52} P_8} = \frac{52!}{(52-8)!}= 30342338208000$

The probability of selecting the correct password if 8 different letters, some may be upper-case and it is case sensitive is:

$P(Correct\ Password)=\frac{1000}{30342338208000} = 3.30\times10^{-11}$

(c)

The number of ways to form a 8 characters password using any 8 letters, upper- or lower-case, and it is case sensitive is, 52⁸.

Then the probability of selecting the correct password if any 8 letters, upper- or lower-case, and it is case sensitive is,

$P(Correct\ Password)=\frac{1000}{52^{8}} = 1.87\times10^{-11}$

(d)

There are 10 digits (0 - 9), 26 uppercase letters and 26 lowercase letters.

Total available characters = 62.

The number of ways to form a 8 characters password using any 8 letters, upper- or lower-case or digits is = 62⁸

Then the probability of selecting the correct password if any 8 characters including letters and digits are used is:

$P(Correct\ Password)=\frac{1000}{62^{8}} = 4.58\times10^{-12}$

58.6790691589 to the nearest hundred thousand

Maurinko [17]

Answer:

58.67907

Step-by-step explanation:

-7 is the hundredth

-9 is the thousandth

0 is the ten thousandth

And 6 is the hundred-thousandth however since the digit following 6 is greater than 5 you round the 6 up to 7.

Select the correct solution for 5x = 50

vovangra [49]

Hi there!

This is the way to solve this one-step equation:

5x=50

We divide both sides by 5 to isolate x:

x=10

Therefore, x=10. Hope it helps.

Find the number of chips needed to make each rectangle prism

Tom [10]

1.

height= 3

length= 5

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

3 x 5 x 4 = 60

We need 60 blocks

2

height= 4

length= 6

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

4 x 6 x 4 = 96

We need 96 blocks

3

height= 2

length= 3

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

2 x 3 x 4 = 24

We need 24 blocks

4

height= 4

length= 8

width= 6

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

4 x 8 x 6 = 192

We need 192 blocks

5

height= 2

length= 6

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

2 x 6 x 4 = 48

We need 48 blocks

6

height= 1

length= 5

width= 3

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

1 x 5 x 3 = 15

We need 15 blocks
