A jury pool has 15 people that are married and 20 people that are not married, from which 12 jurors will be selected. Assuming that each person is equally likely to be chosen and that the jury is selected at random, find the probability that the jury consists of the following. (Give answer as a fraction or a decimal out to at least 4 places. If your answer is very small use scientific notation out to 4 decimal places for example 3.3421E-6.)
Answer:
a
[tex]P(K) = 0[/tex]
b
[tex]P(Z) = 0[/tex]
c
[tex]P(W) = 0.1016[/tex]
d
[tex]P(R) = 0.29[/tex]
Step-by-step explanation:
From the question we are told that
The number of married people is k = 15
The number of people that are not married is u = 15
The number of people selected is e = 12
The total number of people is n = 30
Generally the number of ways of selecting 12 people from the married people is mathematically represented as
[tex]B = ^k C_e[/tex]
Here C stands for combination hence we will be making use of the combination functionality in our calculators
[tex]B = ^{15} C_{12}[/tex]
=> [tex]B = 455[/tex]
Generally the number of ways of selecting 0 people from the not married people is mathematically represented as
[tex]A = ^u C_0[/tex]
=> [tex]A = ^{15} C_0[/tex]
=> [tex]A = 1[/tex]
Generally the number of ways of selecting 12 people from the total number of people is mathematically represented as
[tex]D = ^{n} C_{12}[/tex]
=> [tex]D = ^{30} C_{12}[/tex]
=> [tex]D = 8.6493225 *10^{7}[/tex]
Generally the number of ways of selecting 12 people from the married people is equal to the number of ways of selecting 12 people from not married, also the number of ways of selecting 0 people from the not married is equal to the number of ways of selecting 0 people from the married people, all this is because the number of married people is equal to the number of not married people
Generally the number of ways of selecting 8 people from the married people is
[tex]E = ^{k} C_{8}[/tex]
=> [tex]E = ^{15} C_{8}[/tex]
=> [tex]E =6435[/tex]
Generally the number of ways of selecting 4 people from the not married people is
[tex]F = ^{u} C_{4}[/tex]
=> [tex]F= ^{15} C_{4}[/tex]
=> [tex]F=1365[/tex]
Generally the number of ways of selecting 6 people from the married people is
[tex]G = ^{k} C_{6[/tex]
=> [tex]G= ^{15} C_{6}[/tex]
=> [tex]G=5005[/tex]
Generally the number of ways of electing 6 people from the married people is equal to the number of ways of selecting 6 people from the not married people
Generally the probability that the jury consists of all married people is mathematically represented as
[tex]P(K) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]
=> [tex]P(K) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]
=> [tex]P(K) = 0.000005[/tex]
=> [tex]P(K) = 0[/tex]
Generally the probability that the jury consists of all not married people is mathematically represented as
[tex]P(Z) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]
=> [tex]P(Z) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]
=> [tex]P(Z) = 0.000005[/tex]
=> [tex]P(Z) = 0[/tex]
Generally the probability that the jury consists of 8 married and 4 that are not married is mathematically represented as
[tex]P(W) = \frac{ E * F}{D}[/tex]
=> [tex]P(W) = \frac{ 6435 * 1365}{8.6493225 *10^{7}}[/tex]
=> [tex]P(W) = 0.1016[/tex]
Generally the probability that the jury consists of 6 married and 6 that are not married. is mathematically represented as
[tex]P(R) = \frac{G * G}{D}[/tex]
[tex]P(R) = \frac{5005 * 5005}{8.6493225 *10^{7}}[/tex]
=> [tex]P(R) = 0.29[/tex]
The polynomial p is graphed. What is the remainder when p(x) is divided by (x-3)? Your answer should be an integer.
The remainder when p(x) is divided by (x-3) is 1
RemaindersThe remainder of a polynomial can be gotten from graphs and by using the remainder theorem
Divisors
The divisor of an expression is the number or expression that divides an expression
The divisor of the polynomial is given as:
x - 3
Set the above divisor to 0
[tex]x - 3 = 0[/tex]
Add 3 to both sides of the equation
[tex]x = 3[/tex]
Next, we determine P(3) from the graph.
From the graph, we have:
[tex]P(3) = 1[/tex]
Hence, the remainder is 1

Scores of high school seniors taking the English Regents examination in New York State are normally distributed with a mean of 70 and a standard deviation of 10.
Required:
a. Find the probability that a randomly selected high school senior will have a score between 70 and 75.
b. Find the probability that a randomly selected high school senior will have a score higher than 85.
Answer:
0.19146
0.066807
Step-by-step explanation:
Given that :
Mean (m) = 70
Standard deviation (s) = 10
a. Find the probability that a randomly selected high school senior will have a score between 70 and 75.
X ≤ 70 :
Using : z = (x - m) / s
Z = (70 - 70) / 10
Z = 0 / 10
Z = 0
P( Z < 70) = 0.500
X ≤ 75
z = (x - m) / s
Z = (75 - 70) / 10
Z = 5 / 10
Z = 0. 5
P(z < 0.5) = 0.69146
0.69146 - 0.5000
= 0.19146
b. Find the probability that a randomly selected high school senior will have a score higher than 85.
X ≥ 85
z = (x - m) / s
Z = (85 - 70) / 10
Z = 15 / 10
Z = 1.5
P(z > 1.5) = 0.066807 ( Z probability calculator)

What are the values of the mean and standard deviation after converting all pulse rates of women to z scores using ? nothing nothing The original pulse rates are measure with units of "beats per minute". What are the units of the corresponding z scores? Choose the correct choice below. A. The z scores are measured with units of "minutes per beat." B. The z scores are measured with units of "beats per minute." C. The z scores are measured with units of "beats." D. The z scores are numbers without units of measurement.
Answer:
(1) 0 and 1
(2) Correct option D
Step-by-step explanation:
It is provided that pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute.
Let X denote the pulse rates of women.
(1)
Let us consider a random variable, X that follows N (µ, σ²), then [tex]Z=\frac{X-\mu}{\sigma}[/tex], is a standard normal variate with mean, E (Z) = 0 and variance V (Z) = 1.
That is, Z follows N (0, 1).
In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.
Thus, z-scores are a type of standardized scores.
The values of the mean and standard deviation after converting all pulse rates of women to z scores are 0 and 1 respectively.
(2)
The z scores are numbers without units of measurement.
The probability that a college graduate will find a full time job within three months after graduation from college is .27. Three college students, who will be graduating soon, are randomly selected. What is the probability that all three of them will find full-time jobs within three months after graduation from college
Answer:
The probability that all three of them will find full-time jobs within three months after graduation from college is 0.0197.
Step-by-step explanation:
Let X denote the number of college graduates who will find a full time job within three months after graduation from college.
A random sample of 3 college students, who will be graduating soon, are selected.
The probability of X is, p = 0.27.
Each student is independent of the other to find a full time job within three months after graduation from college.
The random variable X follows a binomial distribution with parameter n = 3 and p = 0.27.
Compute the probability that all three of them will find full-time jobs within three months after graduation from college as follows:
[tex]P(X=3)={3\choose 3}(0.27)^{3}(-0.27)^{3-3}[/tex]
[tex]=1\times 0.019683\times 1\\=0.0197[/tex]
Thus, the probability that all three of them will find full-time jobs within three months after graduation from college is 0.0197.

Bam scored 12 points per game last year. This year he scores 19 points per game. By what percent did his point production change?
Answer:
[tex]\%Change = 58.33\%[/tex]
Step-by-step explanation:
Given
[tex]Initial = 12[/tex]
[tex]Final = 19[/tex]
Required
Determine the percentage change
Percentage change is calculated as thus:
[tex]\%Change = \frac{|FInal - Initial|}{Initial} * 100\%[/tex]
[tex]\%Change = \frac{|19 - 12|}{12} * 100\%[/tex]
[tex]\%Change = \frac{|7|}{12} * 100\%[/tex]
[tex]\%Change = \frac{7}{12} * 100\%[/tex]
[tex]\%Change = \frac{7* 100\%}{12}[/tex]
[tex]\%Change = \frac{700\%}{12}[/tex]
