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:

[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]

Consider the finite strings of length 100 drawn from the alphabet of 4 letters {a,b,c,d}. How many of those strings use no more than two different letters?
Answer:
[tex]2^{100} * 6[/tex]
Step-by-step explanation:
length of finite strings = 100
number of letters : 4 { a,b,c,d }
Determine the number of strings that use ≤ two different letters
since the number of letters is 4 and we are allowed to make use of at most 2 different letters
Then the number of ways will be : [tex]^{4} C_{2}[/tex] = 6 ways
now considering the length of the Finite strings
The number of strings that use no more than two different letters
= [tex]2^{100} * 6 ways[/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)
a square had a side length of 9cm. what is the area?
Answer:
81cm^2
Step-by-step explanation:
Answer:
81
Step-by-step explanation:
Let's do a quick refresher on how to find area.
l = length
w = width
a = area
a = l(w)
Since one side is 9cm, and all the sides are equal, you multiply 9x9.
Nine times nine is 81.

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.
What is the equation of the line described below written in slope-intercept form?
the line passing through point (4, -1) and perpendicular to the line whose equation is 2x - y - 7 = 0
y=-3x+1
y= 2x-1
y=2x + 1
Answer:
y = - (1/2) x + 1
Step-by-step explanation:
The given equation of the line is:
2 x - y - 7 = 0
solving for y gives:
2 x - 7 = y
so y = 2 x - 7
where the slope is "2", which is fundamental to know in order to construct a perpendicular line to it by using the "opposite of the reciprocal" of the given slope.
So in our case, the slope of the perpendicular line must be: "- 1 / 2" (negative one half).
now we can build the equation of the new line, using this slope and requesting the point (4, -1) to be in it:
y = - (1/2) x + b
-1 = - (1/2) (4) + b
-1 = - 2 + b
solve for b:
b = 2 - 1 = 1
Then the equation of the perpendicular line is:
y = - (1/2) x + 1
y= -1/2 x+1
Step-by-step explanation:
2x-y-7=0
2x-7=y
y=2x-7

Jimmy wants to serve iced tea at his birthday party. He purchases 14 containers filled with 1.5 liters of tea. Approximately how many gallons of tea did he purchase? (1 gallon is about 3.8 liters)
Answer:
5.5 gallons
Step-by-step explanation:
The answer is 5.5 gallons.
Number of containers = 14
Amount in each container = 1.5 liter
1 gallon = 3.8 liter
Find:Total amount of tea in gallon
Computation:Total amount of tea in gallon = Number of containers × Amount in each container / 3.8
Total amount of tea in gallon = 14 × 1.5 / 3.8
Total amount of tea in gallon = 21 / 3.8
Total amount of tea in gallon = 5.5 liter (Approx.)
