The answer would be the opposite of the probability that it will rain. So if 1/11 is how likely it will rain, you would take the opposite. The probability that it will not rain is does not include how much it will rain. So the total fraction, 11/11 minus how much it will rain, 1/11 is 10/11. The answer is 10/11.

I have added this one to the puzzles.

I have posted Bertie's answer but I have whited it out.  I don't want to spoil anyone's fun LOL

If you want the answer you will have to ask for it :))

I think....

4 red and 2 white

P(white removed and then red is chosen) = 2/6 * 5/6 = 10/36 = 5/18

P(red removed and then red is chosen) = 4/6 * 1/2 = 4/12 = 1/3 = 6/18

P(red is chosen) = 5/18 +6/18 = 11/18

x^2+3x-4

_________<0

x^2+x

This is a kinda' funky one....!!!!!

Factoring the denominator, we have x(x+1)  which means that we will have  vertiical asymptotes at x = -1 and x = 0

Factoring the numerator, we have (x +4)(x - 1) < 0

Setting each factor to 0, we have x = -4 and x = 1     .....so.....

Our possible answers come from these intervals (-∞, -4) (-4, -1) (-1, 0) (0, 1) (1, ∞)

Thanks Bertie,

That looks like one convoluted answer. I shall give it closer scrutiny :)

Maybe there is more than 1 convoluted answer?

I wonder if the anon poster has an answer?    :D

The base has a surface area of 54......so the rest of the surface area is  408 - 54 =  354

So

2h(9 + 6)  = 354    divided both sides by 2

h(15)  = 177      divide both sides by 15

h = 177/15  =  11.8 units

(x + 3)(2x - 1)(2 - x) > 0

Setting each factor to 0, we have the following possible solution intervals....

(-∞, -3), (-3, 1/2), (1/2, 2), (2, ∞ )

We can pick a point in each interval to see if that interval satisfies the inequality

Picking -5 in the first interval will make the inequality true

This lets us know that the other interval that will "work" occurs on (1/2, 2)

Then, the solutions come from (-∞, -3) and (1/2, 2)

I didn't want to spoil your, or someone elses, enjoyment. The answer is in a private message, publish it if you wish.

You know, she probably can cook up some great variations on pi.

-12+d= 14      add 12 to both sides

d = 26

true because $${\mathtt{4}}{kg} = {\mathtt{4}} \Rightarrow {\mathtt{kg}} = {\mathtt{1}}$$

The formula for the equation of a circle is  (x - a)² + (y - b)²  =  c².

The center is at (a, b), the radius is c.

To find the radius, use the distance formula from (7,7) to (12,9):

   r  =  √[ (x₂ - x₁)² + (y₂ - y₁)² ]  =   √[ (12 - 7)² + (9 - 7)² ]  =  √[ (5)² + (2)² ]  =  √29

Putting this all together:  (x - 7)² + (y - 7)²  =  (√29)^{2   --->   (x - 7)2 + (y - 7)2  =  29}

The only way that both can come up with maroon sides is for both to be maroon, which will occur  4/20 x 4/20  =  16/400 times.

Both teal:  7/20 x 7/20  =  49/400.

Both cyan:  8/20 x 8/20  =  64/400.

Both sparkly:  1/20 x 1/20  =  1/400.

In each of the above cases, the dice match, so add all the individual possibilities:

     16/400 + 49/400 + 64/400 + 1/400  =  130/400

Since there are 6 possibilities for the first die and 6 possibilities for the second die, there is a total of 36 different sums.

Of all these sums, only 1 + 1 = 2 and 6 + 6 = 12, falls outside the limits of 3 and 11.

So, there are 34 sums that work, giving a probability of 34/36.

There is so many ways.

If you want a decimal approximation, enter the expression into the calculator.

If you don't want a decimal approximation, what type of answer do you want?

2(x - 3)  =  2x + 5

Multiply out the left side:

2x - 6  =  2x + 5

Subtract 2x from both sides:

    -6  =  5

Since this is impossible, this "equation" cannot be solved.
