Let Y1, Y2, ...,Yn be a random sample from a population with probability mass function of the form P, if y=1, = p(Y = y) = = 1-p, if y=0, - 0, 0.W., 2 a where 0 < p < 1. Using Definition 9.3, answer the following question. Is ên = _Y1 + jY2 + Y3 sufficient estimator of p. [5 Points).
No, the estimator ên = Y1 + Y2 + Y3 is not a sufficient estimator of p.
To determine if the estimator ên = Y1 + Y2 + Y3 is a sufficient estimator of p, we need to verify if the conditional distribution of the sample given the estimator does not depend on the parameter p.
The probability mass function (PMF) of the sample is given by:
P(Y1 = y1, Y2 = y2, Y3 = y3) = p^(y1+y2+y3)(1-p)^(3-(y1+y2+y3))
Now, let's consider the conditional distribution of the sample given the estimator ên:
P(Y1 = y1, Y2 = y2, Y3 = y3 | ên = c) = P(Y1 = y1, Y2 = y2, Y3 = y3 | Y1 + Y2 + Y3 = c)
To calculate this conditional probability, we can use the fact that the sum of the three random variables Y1, Y2, and Y3 follows a binomial distribution with parameters n = 3 and p.
The PMF of the sum Y1 + Y2 + Y3 is given by:
P(Y1 + Y2 + Y3 = c) = C(3, c)p^c(1-p)^(3-c)
Since the conditional distribution of the sample given the estimator depends on the parameter p, the estimator ên = Y1 + Y2 + Y3 is not a sufficient estimator of p.
In conclusion, based on Definition 9.3, the estimator ên = Y1 + Y2 + Y3 is not a sufficient estimator of p because the conditional distribution of the sample given the estimator depends on the parameter p.

For the first question, the answer is option C) 172. On day 1, Joe remembered all 200 words. On day 2, he remembered 10% fewer words than he did on day 1. This means he remembered 90% of the words he memorized on day 1.
90% of 200 is (90/100) x 200 = 180 words.
On day 3, Joe remembered 10% fewer words than he did on day 2. This means he remembered 90% of the words he memorized on day 2.
90% of 180 is (90/100) x 180 = 162 words.
Therefore, Joe remembered 162 words on day 3. So, the answer is option B.

what does polynomial t3(x) mean in taylor series
In a Taylor series, the polynomial t3(x) represents the third degree Taylor polynomial of a function. It is an approximation of the function near a specific point, obtained by taking the first three terms of the Taylor series expansion.
The polynomial t3(x) is given by t3(x) = f(a) + f'(a)(x-a) + (f''(a)/2!)(x-a)^2 + (f'''(a)/3!)(x-a)^3, where f(a) is the value of the function at the point a, f'(a) is its first derivative, f''(a) is its second derivative, and f'''(a) is its third derivative.
In the context of Taylor series, polynomial T3(x) refers to the third-degree Taylor polynomial. It is an approximation of a given function using the first four terms of the Taylor series expansion. The general formula for the Taylor series is:
f(x) ≈ f(a) + f'(a)(x-a) + f''(a)(x-a)^2/2! + f'''(a)(x-a)^3/3! + ...
For T3(x), you'll consider the first four terms of the series:
T3(x) = f(a) + f'(a)(x-a) + f''(a)(x-a)^2/2! + f'''(a)(x-a)^3/3!
Here, f(a) represents the function value at the point 'a', and f'(a), f''(a), and f'''(a) represent the first, second, and third derivatives of the function evaluated at 'a', respectively. The T3(x) polynomial approximates the given function in the vicinity of the point 'a' up to the third degree.

The citizens of a certain community were asked to choose their favorite pet. The pie chart below shows the distribution of the citizens' answers. If there are 140,000 citizens in the community, how many chose Fish or Cats?
Incomplete Question:
The content of the pie chart is as follows:
Hamsters = 9% ; Snakes = 10% ; Cats = 23%
Birds = 21% ; Dogs = 26% ; Fish = 11%
Answer:
The number of citizens who chose cat or fish is 47,600
Step-by-step explanation:
Given
Number of citizens = 140,000
Required
Determine the number of those that chose fish or cats
First, we need to calculate the percentage of those whose pets are either cats or fish
\(Percentage = Cat + Fish\)
Substitute 23% for cat and 11% for fish
\(Percentage = 23\% + 11\%\)
\(Percentage = 34\%\)
Next, is to multiply the calculated percentage by the number of citizens
\(Cat\ or\ Fish = Percentage * Number\ of\ Citizens\)
\(Cat\ or\ Fish = 34\% * 140000\)
\(Cat\ or\ fish = 47600\)
Hence, the number of citizens who chose cat or fish is 47,600
the number of citizens who chose cat or fish is 47,600
The calculation is as follows;= Number of citizens × total percentage
\(= 140,000 \times (23\% + 11\%)\\\\= 140,000 \times 34\%\)
= 47,600

Evaluate the triple integral y^2 dV where t is the solid tetrahedron with vertices (0,0,0), (2,0,0), (0,2,0), (0,0,2)
To evaluate this triple integral, we need to set up the bounds for each variable. Since the solid tetrahedron is defined by the vertices (0,0,0), (2,0,0), (0,2,0), and (0,0,2), we know that:
∫(from 0 to 2) ∫(from 0 to 2-x) ∫(from 0 to 2-x-y) y^2 dz dy dx
Now, integrate with respect to z:
= ∫(from 0 to 2) ∫(from 0 to 2-x) y^2(2-x-y) dy dx
Next, with respect to y:
= ∫(from 0 to 2) [-y^3/3 + xy^2 - y^2x/2] (from 0 to 2-x) dx
= ∫(from 0 to 2) [-8x^3/3 + 4x^4/3] dx
Finally, integrate with respect to x:
= [-2x^4/3 + x^5/3] (from 0 to 2)
= [-16/3 + 32/3] - 0
= 16/3

Problem 3: Consider a geometric sequence an = µ, for some r € (0,1). Suppose we have a probability distribution on the set Z+ of positive integers, so that n € Z+ is chosen with probability an =
A mathematical function called probability distribution expresses the possibility of various outcomes or occurrences happening under a specific set of conditions.
An open interval of values (0, 1) and a geometric sequence with the general term a = are provided to us in this problem. A probability distribution on the set Z+ (the set of positive integers) is also provided to us, with the condition that the chance of selecting n is equal to a = /(1 - r).
Making sure that the total probability over all feasible values of n is equal to 1 is necessary in order to examine this probability distribution. Let's check this out:
Sum of probabilities = ∑(an) for n = 1 to infinity
= ∑(µ/(1 - r)) for n = 1 to infinity
= µ/(1 - r) * ∑(1) for n = 1 to infinity
= µ/(1 - r) * infinity
Since r is in the open interval (0, 1), (1 - r) > 0, and when multiplied by infinity, it approaches infinity. Therefore, the sum of probabilities is infinity. This means that the given probability distribution does not satisfy the condition for a valid probability distribution, where the sum of probabilities should be equal to 1.
Hence, the probability distribution described in the problem is not well-defined.

one package of sugar cookie dough and one package of oatmeal cookie dough.
Answer:
Sugar cookie dough packages cost 14 dollars each, and oatmeal cookie dough packages cost 16 dollars each.
Step-by-step explanation:
Let s equal the cost of a sugar cookie dough package, and o equal the cost of oatmeal cookie dough packages.
6s + 2o = 116
9s+12o = 318
therefore,
18s+6o = 348
18s+24o = 636

Understanding Isosceles TriangleAn isosceles triangle is a type of triangle that has two sides of equal length. This means that two of the three sides of the triangle are congruent. The angles opposite the congruent sides are also congruent.
Given an isosceles triangle with the following properties:
PQ = x + 0.1
PR = 3x - 0.4
RQ = x + 1.4
But
PR = RQ (equal sides of isosceles triangle)
with this fact, we can calculate the value of x
Recall that:
PR = RQ
3x - 0.4 = x + 1.4
3x - x = 1.4 + 0.4
2x = 1.8
x = 0.9
Knowing the value of x now, we can substitute to the above equations:
Recall:
PQ = x + 0.1
= 0.9 + 0.1
PQ = 1.0
RQ = x + 1.4
= 0.9 + 1.4

Find the midpoint of $\overline{pq}$ with endpoints $p\left(-4,\ 3\right)$ and $q\left(4,-1\right)$. Then write an equation of the line that passes through the midpoint and is perpendicular to $\overline{pq}$. This line is called the perpendicular bisector.
Equation of the line that passes through the midpoint and is perpendicular to PQ is 2x - y +1 = 0.
One way to describe a perpendicular bisector is as a line segment that cuts through another line segment at a 90 degree angle. Simply said, a perpendicular bisector separates a line segment into two equal halves by intersecting it at a 90° angle. Measuring a line segment that needs to be bisected will help you discover a perpendicular bisector.
The midway of the measured length can then be determined by dividing it by two. From this center, extend a line at a 90-degree angle. All you need to do to determine the perpendicular bisector of two points is to discover their midpoint and negative reciprocal, then enter these results into the slope-intercept form of the equation for a line.
Here points are P( -4 ,3 ) and Q ( 4,-1)
Mid -point of PQ :
\(=(\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )\\\\=(\frac{-4+4}{2} ,\frac{3-1}{2} )\\\\=(0,1)\\\)
Slope of PQ:
\(m = \frac{y_{2}{-y_{1} } }{x_{2}{-x_{1} }} \\\\m =\frac{-1-3}{4+4}\\\\ m= \frac{-4}{8} \\\\m = \frac{-1}{2}\)
The slope of the line is Perpendicular to PQ
so, slope 2= -1/m
slope 2 = -1/(-1/2)
slope 2 = 2
Equation of the line that passes through the midpoint and is perpendicular to PQ
\(y-y_{1} =m(x-x_{1}) \\y-1 =2(x-0}) \\\\y-1=2x\\\)

This month Christy sold $1,495.00 worth of food storage container sets. What is Gina's total graduated commission?
Answer:
Total commission= $377.75
Step-by-step explanation:
Giving the following information:
She earns a 12 percent commission on her first $350 worth of sales, 25 percent on the next $650 in sales, and 35 percent on all sales exceeding $1,000.
First, we need to determine the total commission formula:
Total comission= x*0.12 + y*0.25 + w*0.35
x= sales up to $350
y= sales from $351 up to $1,000
w= sales from $1,001 to infinity
Now, for $1,495
Total commission= 350*0.12 + 650*0.25 + 495*0.35
Total commission= $377.75

If the star Aldebaran rises tonight at 2:00 a.m., when do you expect it to rise next month?
a) 11:00 pm.
b) midnight.
c) 1:00 am. d) 2:00 am. e) 3:00 am
Your answer is option b)
The time at which a star rises shifts approximately 4 minutes earlier each day, due to Earth's orbit around the Sun. Since there are roughly 30 days in a month, we can calculate the change in the rise time of Aldebaran over the course of a month.
Step 1: Calculate the time change over one month
30 days * 4 minutes per day = 120 minutes
Step 2: Convert minutes to hours
120 minutes ÷ 60 minutes per hour = 2 hours
Step 3: Subtract the time change from the current rise time
2:00 am - 2 hours = 12:00 am (midnight)
Therefore, you can expect Aldebaran to rise next month at midnight. The correct answer is b) midnight.
