A radio station runs a promotion at an auto show with a money box with 15 $100 tickets, 13 $50 tickets, and 12 $25 tickets. The box contains an additional 20 "dummy”tickets with no value. Three tickets are randomly drawn. Find the probability that all three tickets have no value.
Using the hypergeometric distribution, it is found that there is a 0.0333 = 3.33% probability that all three tickets have no value.
The tickets are drawn without replacement, hence, the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. N is the size of the population. n is the size of the sample. k is the total number of desired outcomes.In this problem:
There is a total of 15 + 13 + 12 + 20 = 60 tickets, hence [tex]N = 60[/tex].Of those, 20 are "dummy" tickets, hence [tex]k = 20[/tex].Three tickets are randomly drawn, hence [tex]n = 3[/tex].The probability that all three tickets have no value is P(X = 0), hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,60,3,20) = \frac{C_{20,3}C_{40,0}}{C_{60,3}} = 0.0333[/tex]
0.0333 = 3.33% probability that all three tickets have no value.

In 2007, Joelle spent $6,600 on her health care. If this amount increased by 3 percent per year, what would be the amount Joelle spent in 2017 for the same health care
Answer: 8,580
Step-by-step explanation:
The equation for the years are 6,600+y(0.03x), x being the original healthcare price 6,600, and y being the number of years elapsed since 2007. Since 10 years have elapsed, the answer would be
6,600+10(198)
Or 6,600+1,980
8,580
How to answer this question
Answer:
15cm
Step-by-step explanation:
As we know that in two similar triangles the corresponding sides are proportional . So that ,
=> 4/10 = 6/AB
=> AB = 6 * 10/4
=> AB = 6 * 5/2
=> AB = 15 cm
Answer:
Ans: C) 15cm
Step-by-step explanation:
first you need to find its corresponding sides,
so, 10÷4=2.5
therefore, 6×2.5=15cm (multiple if we are find the big shape)
So, Ans: is 15cm
These triangles are similar. Find the missing

help me pleaee with the ,math plro ne
Answer:
$213.41
Step-by-step explanation:
To do this question, you have to use the formula for compound interest:
A=P(1+r/n)^nt
The A is the final amount of money you make which is $237.60. P is your initial amount that you are trying to solve for. R is the rate of interest. However, for r you have to convert the percent into a decimal so divide 1.2 by 100, which would be 0.012. N is the number of times it is compounded annually which is once. And finally, t is the number of years taken, which is 9. If you substitute the numbers into the equation it should look like this:
237.60=P(1+0.012/1)^1*9
If you solve for P, you should get $213.41.
Hope this helps :)

Explain how the events of the story would have been different if Gilman had chosen to write in third person, or another character’s first-person point of view.
Answer:
Changing the point of view will cause completely different narrative of a story. You will never know the character's own thoughts, motifs of doing something and his/her perception of everything will not be that clear as it can be depicted in first point of view, when character tell you his story personally. If it was narrated in first person from other character you would never found out what is really true in the story.

Answer:
-0.01x² + 4x + 200
Step-by-step explanation:
To find the difference in profit between the two companies we need to subtract the polynomials.
So,
________________
-0.03x² + 25x - 1500
MINUS
-0.02x² + 21x - 1700
________________
(-0.03x² - (-0.02x²)) = -0.01x²
(25x - 21x) = 4x
(-1500 - (-1700)) = 200
Thus, the difference is
-0.01x² + 4x + 200

3) Anna is selling tickets to the school's gymnastics competition. On the first day, she sells 5 adult tickets and 6 child tickets for a total of $58.00. On the second day, she sells 8 adult tickets and 11 child tickets for a total of $97.00. Which system of linear equations can be used to determine the cost of each adult ticket (x) and each child ticket (y)?
A) 5x + 6y = 58 8x + 11y = 97
B) x + y = 155 x + y = 30
C) 5x − 6y = 58 8x − 11y = 97
D) x + y = 58 8x + 11y = 97
Answer:
I believe it's A) 5x + 6y = 58 8x + 11y = 97
Step-by-step explanation:
Reason is, adult tickets and child tickets are two different things, so they require two different variables, and two different equations because they have two different sums. (This was probably already obvious to you though).

Please help me out I need this question answered.
If a b or c are not the answer please tell me because I forgot to write down d.
Step-by-step explanation:
Length of hypotenuse = c
Length of legs = a and b
Hence,
→ a² + b² = c²
→ b² = c² - a²
→ b = √(c² - a²)
First one is correct. [a]
Now,
By Pythagoras theorem,
→ a² + b² = c²
Third one is correct too. [c]
→ a² + b² = c²
→ a² = c² - b²
Second one is also correct. [b]
So, the last option [D] would be the answer.Step-by-step explanation:
The second leg's length is 12.
Explanation:
Math Warehouse
We'd use the pythagorean theorem to solve for the other leg's length. As the image suggests, we'd use the theorem, a2+b2=c2.
If one leg is 9, that's our a value.
If the hypotenuse is 15, that's our c value.
Now we just have to find the b value.
Plugging in the variables, 92+b2=152.
92=81.
152=225.
81+b2=225. Subtract 81 from both sides.
b2=144. Square root both sides.
√b2=b and √144=12, so b=12

Answer:
Step-by-step explanation:
First, you have to get the equation into y = mx + b form:
-y = -5x + 0
y = 5x + 0 (this is your equation)
Basically, the 5x is your slope. Plot a point at the origin (0,0) since that is your y-intercept, and then from there, go five units up, and one unit to the right. Repeat as you're going up. When you're going down, just do the opposite. Go 5 units down, and 1 unit to the left. Once plotted, just connect it.
