Answer: I think It is B) because it's definitely not C). But it could also be A like the answer above said. (I'm very very sorry if it's not correct!)

B) -6÷3 ?

I tried to figure it out but i can't. i need to show the work and i don't know how to do it.​

Integration Formula:

\int\limits {x}^{n} \, dx =\frac{x^{n+1}}{n+1} + C

Integrate each term:

\int\ {x^{2}} \, dx = \frac{x^{3}}{3}

\int\ {x} \, dx =\frac{x^2}{2}

\int\ {5} \, dx = 5x

\int\ {x} \, dx =\frac{x^2}{2}

\int\ {2} \, dx = 2x

Altogether this becomes:

\frac{\frac{x^3}{3} - \frac{x^2}{2}-5x }{ \frac{x^2}{2}+2x}

Your limits are 1 and 2. Substitute both numbers into the equation and minus them from each other.

x = 2:

\frac{\frac{2^3}{3} - \frac{2^2}{2}-5(2) }{ \frac{2^2}{2}+2(2)}

-

x = 1:

[tex]\frac{\frac{1}{3} - \frac{1}{2}-5 }{ \frac{1}{2}+2}[/tex]

x = 2:

\frac{\frac{8}{3} - \frac{4}{2}-10 }{ \frac{4}{2}+4}

-

x = 1: \frac{\frac{8}{3} - 2-10 }{ 2+4}

=

-1.212317928

Now convert all the answers to integers and see which one matches -1.212317928:

Because it's a negative number, we know it can only be A or B.

(A) = -1.212317928

(B) = -1.19047619

The answer is A: -\frac{3}{2} +In\frac{4}{3}

<h2>(A) - 3/2 = ln 4/3</h2>

When two six-sided dice are rolled what is the probability that the product of their scores will be greater than six?
Pachacha [2.7K]

Answer:   \bold{\dfrac{11}{18}}

<u>Step-by-step explanation:</u>

Think of the products row by row:

11  12  13  14  15  16  - 0 products greater than 6

21 22 23 24 25 26  - 3 products greater than 6

31 32 33 34 35 36  - 4 products greater than 6

41 42 43 44 45 46   - 5 products greater than 6

51 52 53 54 55 56  - 5 products greater than 6

61 62 63 64 65 66  - 5 products greater than 6

\dfrac{\text{number greater than 6}}{\text{total possible outcomes}}=\dfrac{22}{36}=\dfrac{11}{18}\ when\ reduced

Mary must choose a new password where the first and last choices are possibly repeated lowercase letters; the second and third
Salsk061 [2.6K]

The number of ways she can choose a password is 3986236800

<h3>In how many ways can she choose a password?</h3>

The given parameters and the possible selection of characters are:

First and last choices are possibly repeated lowercase letters;

There are 26 lower characters.

Since the characters can be repeated, then we have

First = 26

Last = 26

The second and third positions must be distinct uppercase letters

There are 26 upper characters.

Since the characters are distinct, then we have

Second = 26

Third = 25

The fourth position must be a # , $, or & symbol;

So, we have

Fourth = 3

The next four positions are distinct nonzero digits.

There are 9 nonzero digits.

Since the digits are distinct, then we have

Next = 9, 8, 7, 6

The number of ways she can choose a password is

Ways = First * Second * Third * Fourth * Next * Last

So, we have

Ways = 26 * 26 * 25 * 3 * 9 * 8 * 7 * 6 * 26

Evaluate the product

Ways = 3986236800

Hence, the number of ways she can choose a password is 3986236800
