two balls are chosen randomly from an urn containing 5 white, 3 black, and 2 orange balls. suppose that you win $2 for each black ball selected and you lose $1 for each white ball selected. what is the expected amount you will win from this game
Answer:
2.601
Step-by-step explanation:
Given that:
White balls, W = 5
Black balls, B = 3
Orange balls, O = 2
Total = (5 + 3 + 2) = 10
Winning = $2 for each black ball chosen
Winning = - $1 for each white ball
Sample space for making 2 selections ; order does not matter :
{WW, WO, WB, OO, OB, BB}
WW __WO __WB __OO ___OB __BB
-2 ____ - 1 __ 1 ____ 0 ____ 2 ___ 4
WW = 5C2 / 10C2 = 0.2222
WO = (5C1 * 2C1) / 10C2) = 0.222
WB = (5C1 * 3C1) / 10C2) = 0.3333
OO = (2C2) / (10C2) = 0.0222
OB = ((2C1) * (3C1)) / 10C2 = 0.1333
BB = 3C2 / 10C2 = 0.0667
Expected winning = Σx * p(x)
(-2 * 0.222) + (-1 * 0.222) + (1 * 0.333) + (0 * 0.022) + (2 * 0.133) + (4 * 0.667)
= 2.601

The ratio of length to width on a rectangle is
11:3. The perimeter of the figure is 308. what is the
width of the rectangle
Answer:
[tex]Let~the~length~of~rectangle~be~'l'~and~its~width~be~'b'.\\According ~to ~question,\\l:b=11:3\\or, \frac{l}{b} =\frac{11}{3} \\or, l = \frac{11b}{3}\\Also,\\Perimeter~of~the~rectangle=308\\or, 2(l+b)=308\\or, l+b=154\\or, \frac{11 b}{3}+b =154 \\or, \frac{11b+3b}{3} =154\\or, 14b = 154(3)\\or, b=33 units\\So, ~the~width~of~rectangle~is~33units.[/tex]
Alternative method:
[tex]Let~the~length~and~width~of~the~rectangle~be~11x~and~3x.\\Given,\\Perimeter~of~the~rectangle = 308\\or, 2(11x+3x)=308\\or, 14x = 154\\or, x = 11\\Now,\\Width~of~the~rectangle,3x = 3(11)=33 units\\So,~the~width~of~the~rectangle~is~33units.[/tex]
A pet store has 9 puppies, including 2 poodles, 2 terriers, and 5 retrievers. If Rebecka and Aaron, in that order, each select one puppy at random with replacement (they may both select the same one), find the probability that Rebecka selects a terrier and Aaron selects a retriever.
Answer:
5/162
Step-by-step explanation:
Probability of getting terrier = 2/18 = 1/9
Probability of getting retriever = 5/18
5/18 x 1/9 = 5/162

Solve for a.
4/a+4 =-1/a+9
Answer:
a = -8
Step-by-step explanation:
you can solve this proportion by cross-multiplying:
4(a + 9) = -1(a + 4)
now distribute to eliminate parentheses
4a + 36 = -1a - 4
5a + 36 = -4
5a = -40
a = -8

Jamie can paint a wall in 54 minutes Together Connie and Jamie can paint the same wall in 36 minutes How long would it take Connie to paint the same wall by herself
Answer:
The answer is 108
Step-by-step explanation:
I did this for my exam got 100
Together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.
We have given that,
John can paint 1/54 of a wall in 1 minute.
James can paint 1/36 of a wall in 1 minute.
What is the formula for total wall paint in one minute?Total wall paint of both in one minute is calculated by adding the both the paint in one minute it gives us the total paint in one minute
Therefore ,total wall paint in one minute =1/54 + 1/36
So if they work together, they can both paint 1/54 + 1/36 of a wall in 1 minute.
1/54 + 1/36 = 2/108 + 3/108 = 5/108 = 0.04629.
Therefore,together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.

$20.07 / 3 bags = X / 2 bags
multiply both sides by "2 bags" to isolate the unknown X
$20.07 * 2 / 3 = X
Therefore, X = $13.38
