If you roll two fair six-sided dice, what is the probability that both dice show an odd number?

First we need to find the total number of possibilities. We can do this by multiplying the sides on the dice together.

6 x 6 = 36

There are 36 possibilities.
Since there are 3 odd numbers on each dice, multiply 3 x 3 to find the possibilities of odd numbers.

3 x 3 = 9

There are 9 possibilities you can get an odd number.

The answer is 9/36 (simplify to get 1/4) :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

There's a 25 percent chance that both of them land on an odd number.

HELP!!!!:(<br>2.) WHAT'S THE RESULT?

-1+5x

You combine like terms:

Here there are two different ones.

the number without the variable (the 1s) and the one with the variable (5x)

All you have to do is combine them:

1+(-1)+(-1) = 1-1-1 = -1

5x = 5x

So, the answer would be -1+5x

Hope this helps :D

Please work out and explain

Answer:

a = 22

b = 31

c = 13

Step-by-step explanation:

The sum is the same in each row, column, and diagonal.

One of the diagonals is already complete. The sum is:

16 + 25 + 34 = 75

So the first row adds up to 75:

a + 37 + 16 = 75

a = 22

The second row adds up to 75:

19 + 25 + b = 75

b = 31

And the third row adds up to 75:

34 + c + 28 = 75

c = 13

We can check our answer by finding the sum of each column and the other diagonal.

22 + 19 + 34 = 75

37 + 25 + 13 = 75

16 + 31 + 28 = 75

22 + 25 + 28 = 75

Pls can someone answer how to round 5pi to the nearest 10th I’ll give you brain points or whatever

mojhsa [17]

Answer:

Step-by-step explanation:

5 $\pi$ =15.70...

To round a number to the nearest tenth , look at the next place value to the right (the hundredths)which is 0 in this question.

Thus, it will become 15.7

write an equation for the line that passes through the given point and has the given slope m (4,-5);m= -1/4

EastWind [94]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{y = -1/4x - 4}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Slope = -1/4, Point through = (4, -5)}$

Find: $\textsf{Equation for the line that passes through the given point}$

Solution: In order to get the equation, we need to first use the point-slope form to help us sort out our information and then we solve for y.

<u>Plug in the values</u>

$\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}$

$\textsf{y - (-5) = -1/4(x - 4)}$

<u>Simplify and solve for y</u>

$\textsf{y + 5 = -1/4(x - 4)}$

$\textsf{y + 5 = -1/4x + 1}$

$\textsf{y + 5 - 5 = -1/4x + 1 - 5}$

$\textsf{y = -1/4x - 4}$

Therefore, the final answer would be that the equation that has a slope of -1/4 and passes through (4, -5) is y = -1/4x - 4.
