Hi Guest! What's larger:  2/7 or 3/5?

Вероятность вытащить красный мяч равна 4/8=0.5 Вероятность вытащить синий мяч равна 2/8=0.25 Вероятность вытащить зелёный мяч равна 1/8=0.125 Вероятность вытащить белый мяч равна 1/8=0.125 Количество информации в битах равно: I=-(0.5*log2(0.5)+0.25*log2(0.25)+0.125*log2(0.125)+0.125*log2(0.125)=-(-0.5*1-0.25*2-0.125*3-0.125*3)=-(-0.5-0.5-0.375-0.375)=1.75 бит

So 5a+2b=0 and ab=-10. 

Then a = -10/b

Then substitute into 5a+2b= 0  to get 5(-10/b) +2b = 0 to get -50 +2b^2 = 0. 

Then 2b^2 = 50 

b^2 = 25

b = +5 and -5. 

5 is bigger than -5 so the answer is 5

Heartfelt wishes from me too.

In Quadratic Formula      for  this quadratic    a = 10    b = -7     and c = -6

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)          becomes

\(x = {7 \pm \sqrt{7^2-4(10)(-6)} \over 2(10)}\)      which will give you two values of x which are the 'roots' or ' zeroes'  of the equation.....

OK....see if this helps:

2b^2 -50 = 0

2b^2 = 50

b^2 = 25

b = +- 5        

Here is a balloon for the party!!

Use quadratic equation: a=10, b=-7, c=-6, have you not learned the quadratic formula? Search it up, this problem is extremely easy, giving the answer would be funny. this is systematically solved problem

Yeah, Happy B-Day Cphill, suggest you take a break!

you are the  of this website, (and you too melody)

Reverse engineer the function; a+b=5, and b-a=1. So, a=2 and b=3, so h(6) = 12+3 = 15.

tan(48) * 30 + 16

Thank you very much!!

First, find a value of y that could work.

Suppose y is even. This would mean that the expression is (a multiple of 10) + 14x + (a multiple of 10) = 183.

This cannot work because any integer x times 14 is even, and the result must be odd (183).

Now we know y must be odd. Therefore, if we look at the units digits alone, we will have:

0 + (even) + 5 = 183.

This means that the "even" number (we know it is even because it is a multiple of 14) must have a units digit of 8. 28 ends in an 8, so we could try x = 2. This gives us:

20y + 28 + 15y = 183,

35y = 155.

However, 155 is not divisible by 35, so y would not be an integer.

The next number divisible by 14 that ends in 8 is 98. Substituting x = 7 gives us:

70y + 98 + 35y = 183,

105y = 105, 

y = 1.

All this is is strategic trial and error, but it does the job. We get x = 7, y = 1.

The answer asks for the sum, which is 8.

Oh, calculation error. In the previous post I basically meant what you had written, except somehow multiplied by 24 instead of 12...?

Thanks! Exactly what I got!

In the figure, what is the area of triangle ABD? Express your answer as a common fraction.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[ABD] = 5/13 [ABC]

Whenever the denominator = 0    the fxn is undefined

   using Quadratic Formula , we find   that the zeroes are at a = 2 +- sqrt 3

Line with slope 1/3, or slope 1/5?

For slope of 1/3, you go right 3 every 1 you go up: 1x/3 = y, x = 3y

Similarly, 1/5 is 5 for every 1.

Now, you see, the greater the slope, the steeper it is.

1/3 > 1/5

Thus, 1/3 is steeper.

Four non-congruent squares can be drawn.      (overlapping each other)

According to the question, the dials don't go up to nine.

Hi Ginger.  It's always a delight to happen across one of your postings.  I'm sure it didn't escape you that I said "merely very unlucky" was the best answer, not in an absolute sense, but in comparison to the other five choices.  All you did was criticize my reasoning ... you neglected to say which choice you think would be better, perhaps that wasn't an oversight.  

The "e." answer does include the word "very" which, as you've demonstrated – I'm assuming your calculations are accurate, or at least, accurate enough – is an apropos modifier.  Maybe it should have been in an emphasized typeface, but I'm not the one who posted the question.  

I don't play poker often.  In fact, practically never.  But one day I was playing with my daughter and son-in-law, and two teenage grandchildren, using macaroni noodles as chips – uncooked noodles, of course – and I did get a Royal Flush.  No joker, no wild cards at all, just the 10 thru Ace of hearts, and I didn't draw to it, I received it on the deal.  So, unlikely is not synonymous with impossible. 

Goodnight, Gracie.

Assuming you are referring to the slope of lines, 1/3 would be steeper and you can also verify this by going to https://www.desmos.com/calculator/ica0tezl0j 

where you can see that the 1/3 line is steeper.

Hey I don't wanna be mean or anything, but how can you call this little kid an "entitled little punk"? Sure, they may have been rude, but I understand that at those ages you're going through a lot of emotional changes. Maybe back off and make your point in another way that doesn't involve calling names, because that doesn't make you any more mature than they are. By the way the kid stated it, it just sounds like they are lonely, don't understand and want help. Their parents don't help them, and they are just here to get some help. I've never seen this kid around, so they must be new and these must be their first questions.
