Answer:
The best model is hypergeometric distribution.
Step-by-step explanation:
The probability would be best modeled with hypergeometric distribution.
Hypergeometric distribution is a discrete probability distribution that describes the probability of successes in draws, without replacement, which is often employed in random sampling for statistical quality control.
The hypergeometric distribution differs from the binomial distribution in the lack of replacements.
Thus, the best model is hypergeometric distribution.

A local theater charges $8 for adult tickets and $6 for children's tickets to a play. If a group of 24
goes to the theater and pays $164, how many of each ticket type did the group purchase?
Answer:
The theater was attended by 10 adults and 14 children.
Step-by-step explanation:
As the theater charges adults $ 8 and children $ 6 for each ticket, there is a surcharge of $ 2 for each adult. Thus, given that a group of 24 people attended the theater, as a minimum (that is, if they were all children) the establishment should charge $ 144 (6 x 24). Now, since it charges $ 164, there is a difference of $ 20 (164 - 144), attributable to the surcharge paid by adults for each ticket. Thus, since this surcharge is $ 2, dividing 20 by 2 we obtain 10, which is the number of adults who attended the theater.
This is verified by the following calculation:
10 x 8 = 80
14 x 6 = 84
80 + 84 = 164
Therefore, the theater was attended by 10 adults and 14 children.
what is equavilent to (10x+7r-r^(2))+(-6r^(2)-18+5r)
Answer:
−7r^(2)+12r+10x−18
Step-by-step explanation:
Grab the original equation: 10x+7r−r^(2)−6r^(2)−18+5r
For subtraction bits, treat them as negatives: 10x+7r+−r^(2)+−6r^(2)+−18+5r
Combine like terms: (−r^2+−6r^2)+(7r+5r)+(10x)+(−18)
Simplify that, and you get your final answer: −7r^(2)+12r+10x+−18

2(6 + 3n) - 4
i need the answer...
.....
Answer:
See below.
Step-by-step explanation:
2(6 + 3n) - 4 (Given)
12 + 6n - 4 (Distribute)
6n + 8 (Add like terms)
3n + 4 (Divide by a factor of 2)
In case you wanted to solve for n:
2(6 + 3n) - 4 = 0 (Given)
12 + 6n - 4 = 0 (Distribute)
6n + 8 = 0 (Add like terms)
6n = -8 (Substract on both sides)
n = -4/3 (Divide 6 on both sides)
Which graph shows the solution to the system of linear inequalities? x+5y>=5. y<=2x+4
Answer:
The correct answer is B.
Step-by-step explanation:
The solution to the inequalities is (-11/15. 38/15)
Equation of a lineGiven the systen of inequalities expressed as:
x+5y>=5y<=2x+4inequality graphIn order to get the graph that shows the solution and the coordinate of the solution, equate the inequalities to havee:
(5-x)/5 = 2x + 4
5 - x = 10x + 20
20 - 5 = -11x
15 = -11x
x = -11/15
Given that y = 2x + 4
y = -22/15 + 4
y = 38/15
The solution to the inequalities is (-11/15. 38/15)

Portray the cumulative distribution in the form of a cumulative frequency polygon.d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?
Answer:
a. How many employees accumulated less than 3,000 miles?
The number of employees accumulated less than 3,000 miles= 5
So the number of employees accumulated less than 3,000 miles is 5.
d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?
8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.
Step-by-step explanation:
The given frequency distribution representing the number of frequent flier miles accumulated by the employees in a company.
Frequent Flier Miles (000) Frequency
0 up to 3 5
3 up to 6 12
6 up to 9 23

20 POINTS PEOPLE!!!
it was estimated that 200 people would attend game night, but 196 people actually attended what is the percent error, to the nearest percent, of the estimate?
Subtract the two numbers to find the difference:
200-196 =4
Divide the difference by the estimated number:
4/200 = 0.02
Multiply by 100 to change to percent:
0.02 x 100 = 2%
The answer is 2%
2,037 divided by 39 with the remaining
Answer:
53 remainder 23
= 53 23/38
Step-by-step explanation:
Answer:
52 with 9 remaining
Step-by-step explanation:
When dividing this, we find that our whole number we are going to multiply with is 52, and if it was 53 it would be over 2,037. So, we multiply 39 by 52 and get 2,028, which is an extra of 9 remaining.

A2. Find y' and y" for y^2 = x^2
+ sinxy
Answer:
y' = (2x + y cosxy)/(2y + x cosxy)
Step-by-step explanation:
Using implicit differentiation:
y^2 = x^2 + sin xy
2y y' = 2x + cos xy * (xy' + y)
2y y' = 2x + xy' cos xy + y cos xy
2y y' - xy' cosxy = 2x + ycos xy
y' = (2x + y cosxy)/(2y - x cosxy)

Given
z₁ = 4 - 4√3iz₂ = -16iTo find
z₁ - z₂Solution
z₁ - z₂ =4 - 4√3i - (-16i) =4 - 4√3i + 16i =4 - 4(√3i - 4i) =4 - 4(√3 - 4)iCorrect option is C
Answer:
[tex]z1 = 4 - 4 \sqrt{3} i \\ z2 = - 16i \\ z1 - z2 = (4 - 4 \sqrt{3} i) - ( - 16i) \\ = 4 - 4 \sqrt{3} i + 16i \\ = \boxed{4 - 4( \sqrt{3} - 4)i}[/tex]
3) 4-4(√3-4)i is the right answer.
