It Is Very Impossible

Imposible. When you multiply two odd numbers it will always be odd. This is the same with even. If you multiply two even numbers the answer will always be even. This fact will never change. Now when you are adding two odd numbers, this is where it becomes different.take
7 + 5
Both are odd, but the answer is 12.

Kruka [31]

1 dozen = 12

Divide 941 by 12:

941 / 12 = 78.42

So the greatest number of dozens he can make is 78.

Evaluate 5x-\dfrac xy5x−

olga2289 [7]

Answer:

5x - (x/y) = 18 when x=4 and y=2

Step-by-step explanation:

5x - (x/y)

When x=4 and y=2

Substitute the value of x=4 and y=2 into the expression

5x - (x/y)

5(4) - (4/2)

Multiply 5 by 4 and divide 4 by 2

=20 - 2

Subtract 2 from 20

=18

5x - (x/y) = 18 when x=4 and y=2

Answer:

y = -2/7x - 32/7

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

The slope is -2/7

y = -2/7 x+b

We know a point on the line is (5,-6)

Substitute this into the equation

-6 = -2/7(5) +b

-6 = -10/7+b

Add 10/7 to each side

-6 +10/7 = b

-42/7 + 10/7 = b

-32/7 = b

y = -2/7x -32/7

Last year at a certain high school, 12 students sought the nomination for president of the student body. In how many ways could

Vlada [557]

Answer:

<h3>495 different ways</h3>

Step-by-step explanation:

This question bothers on combination. Combination has to do with selection. When selecting r objects from a pool of n objects, this is expressed as;

nCr = n!/(n-r)!r!

For us to choose rank the first 4 choices from 12 students nominated, this can be done in 12C4 number of ways;

12C4 = 12!/(12-4)!4!

12C4 = 12!/8!4!

12C4 = 12*11*10*9*8!/8!*4*3*2

12C4 = 12*11*10*9/24

12C4 = 11880/24

12C4 = 495 ways

Hence this can be done in 495 different ways
