 blue marbles
y = yellow marbles
 Sum = b+y
 The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55 
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes 
0.37/0.55 = .67 or 67%

Much like sound bites of news​ stories, statistical studies are often reduced to​ one- or​ two-sentence "stat-bites." For the​st
Ira Lisetskai [31]

Answer:

Step-by-step explanation:

Given that According to a video streaming​ service, 48% of American couples are​ "cheaters", that is—they promise each other to watch a film​together, but one of them first watches it alone.

Here if this is binomial with two outcomes we can easily say that the other 52% couples go together movies.

But here there are not only two outcomes.

The other possibilities are:

i) Either both do not go to movies

ii) Both cheat and go to movies separately

Thus since there are not exactly two outcomes, we cannot say the other 52% go to movies together.

As much as say that 52% of couples are not cheating in this way.

HELP !!! Use the elimination method to solve the system of equations.
Dafna1 [17]

Answer:

C. (5, -3)

Step-by-step explanation:

4x + 3y = 11

x - y = 8  (multiply by 3) --> 3x - 3y = 24


4x + 3y = 11

3x - 3y = 24

---------------------add

7x = 35

 x = 5


5 - y = 8

y = 5 - 8

y = -3

(5, -3)

Circles M and K are congruent, QR is congrent to LN. Find the length of QR
Novosadov [1.4K]

Given QR is congrent to LN and QR = 4x + 2 and LN = x + 7.

So, QR = LN

Hence, we can set up an equation as following:

4x + 2 = x + 7

4x + 2 - x = x + 7 - x Subtract x from each sides.

3x + 2 = 7 By simplifying.

3x + 2 - 2 = 7 - 2 Subtract 2 from each sides.

3x = 5

\frac{3x}{3} =\frac{5}{3} Divide each sides by 3 to isolate x.

So, x=\frac{5}{3}

Next step is to plug in x=\frac{5}{3} in QR = 4x+2 to get length of QR.

So, QR = 4(\frac{5}{3})+2

=(\frac{20}{3})+\frac{2}{1} Since 2 can be written as 2/1.

By multiplying the second fraction by the common denominator 3.

=(\frac{20}{3})+\frac{2*3}{1*3}

=(\frac{20}{3})+\frac{6}{3} By simplifying the second fraction.

=(\frac{26}{3})

So, QR=\frac{26}{3}
