Answer:

option 3

Step-by-step explanation:

Given

(6a + b)²

= (6a + b)(6a + b)

Each term in the second factor is multiplied by each term in the first factor, that is

6a(6a + b) + b(6a + b) ← distribute both parenthesis

= 36a² + 6ab + 6ab + b² ← collect like terms

= 36a² + 12ab + b²

X°and x+2 are complementary angles then find the angles<br>​
Elanso [62]

Answer:

44° and 46°

Step-by-step explanation:

Complementary angles sum to 90° , thus

x + x + 2 = 90

2x + 2 = 90 ( subtract 2 from both sides )

2x = 88 ( divide both sides by 2 )

x = 44

Thus the 2 angles are 44° and 44 + 2 = 46°

John is choosing a password for an account. He has decided not to use the digit 0 or the letter m. And each letter or number can
kap26 [50]
<em>If this guy doesn't use the letter m, then the first and second characters of the password could be any of the 25 remaining letters.  So, the number of possible combinations of 2 letters is 25 times 25, or 625.  

If he doesn't use the digit 0, how many digits are left to choose from?

The first 2 characters of the password will be letters; after that there come four digits.  How many different combinations of 4 digits are there if 0 is not used?

To obtain the final result, mult. together that 625 and the number of possible combinations of digits just found above.</em>

Answer:

The  probability is  P(I  | \ L ) =0.4

Yes with the additional information that the person logs on everyday the probability increased from  P(I) =  0.3  to P(I |  L )  =  0.4

Step-by-step explanation:

From the question we are told that

   The probability that the user is from outside the country is  P(O) =  0.7

    The probability that the user log on everyday is  P(L) =  0.6

    The  probability that the user log on everyday and he/she is from inside the country  is  P(L| I) =  0.80

Generally using Bayes theorem the the probability that a person is from the country given that he logs on the website every day is mathematically represented as

        P(I  | \ L ) =  \frac{ P(L|I) *  P(I)}{ P(L)}

Here P(I) is the probability that the person log on every day and it is mathematically evaluated as

        P(I)  =  1 - P(O)

          P(I)  =  1 - 0.7

         P(I)  = 0.3

So

      P(I  | \ L ) =  \frac{ 0,8 *  0.3}{ 0.6}

      P(I  | \ L ) =0.4
