A certain town has 25,000 families. The average number of children per family is 2.6, with an SD of 0.80. The distribution is not normal, however, since 20% of the families have no children at all. (a) If one draws a simple random sample of five families from the 25,000, what is the chance that exactly two of the five sample families will have no children
Answers
Answer:
0.2048 = 20.48% probability that exactly two of the five sample families will have no children.
Step-by-step explanation:
For each children, there are only two possible outcomes. Either they have no children, or they do have children. The probability of a family not having children is independent of any other family. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
20% of the families have no children at all.
This means that [tex]p = 0.2[/tex]
Five families:
This means that [tex]n = 5[/tex]
What is the chance that exactly two of the five sample families will have no children?
This is P(X = 2).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{5,2}.(0.2)^{2}.(0.8)^{3} = 0.2048[/tex]
0.2048 = 20.48% probability that exactly two of the five sample families will have no children.

A manufacturing facility is responsible for producing two components that are produced at states 1 (poor), 2 (below average), 3 (average), 4 (good), and 5 (excellent). For the final product (con- sisting of both components) to be acceptable the sum of the two states needs to be at least equal to 6. At the moment, the manufacturing processes are random, and hence each component is equally likely to be at any of the 5 states. Answer the following questions.
Required:
a. What is the probability that a final product is acceptable? What is the probability that a final product is unacceptable?
b. What is the probability that a final product is acceptable given that the first component is produced at a state of 2?
c. What is the probability that the second component was produced at a state of 3 given that the final product is acceptable?
Answers
Answer:
a) i) P( final product is acceptable ) = 3/5
ii) P ( final product not acceptable ) = 2/5
B) P ( final product is acceptable | X =2 ) = 2/5
C) P ( Y = 3 | Final product is acceptable ) = 2/5
Step-by-step explanation:
Given data :
5 states : 1 (poor), 2 (below average), 3 (average), 4 (good), and 5 (excellent)
Number of components produced = 2
X ( component 1 ) ∴ P(X) = 1/5
Y ( component 2 ) ∴ P(Y) = 1/5
Aim : Sum of Final product needs to be ≥ 6
A) Probability of a final product been acceptable and also unacceptable
P( final product is acceptable ) ; P(X + Y ≥ 6 )
= 1/5 ∑ P( Y ≥ 6 - x )
= 1/5 ( P( Y ≥ 5 ) + P( Y ≥ 4 ) + P( Y ≥ 3 ) + P( Y ≥ 2 ) + P( Y ≥ 1 )
= 1/5 ( 1/5 + 2/5 + 3/5 +4/5 + 1 )
= 3/5
P ( final product not acceptable ) = 1 - 3/5 = 2/5
B) P ( final product is acceptable | X =2 )
∴ P ( Y ≥ 4 )
= 2/5
C) P ( Y = 3 | Final product is acceptable )
∴ P ( X ≥ 3 ) ≠ P( Y ≥ 3 ) ( because they are not independent )
= 1 - 3/5 = 2/5.

How to find that a given condition can be modeled by binomial distribution?Binomial distributions consist of n independent Bernoulli trials.
Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
The probability that out of n trials, there be x successes is given by
Use binomial distribution, with p =0.20, n=5, x=3
[tex]P(X=x)=C(n,x)p^x (1-p)^{n-x}[/tex]
P(X> = 3)
[tex]=1-(P(X=0)+P(X=1)+P(X= 5 ))\\=1-(C(20,0)0.2^0 (0.8)^{20-0}+C(20,1)0.2^1 (0.8)^{20-1}+C(20,2)0.2^2 (0.8)^{20-2})[/tex]

For positive acute angles A and B it is known that tan A 15/8 and Cos B 12/37 find the value of Cos (A+b) being in simplest form
Answers
Answer:
Step-by-step explanation:
Cos(A + B) = Cos(A)*Cos(B) - Sin(A)*Sin(B)
Find The Hypotenuse of A
Tan(A) = Opposite / Adjacent
Tan(A) = 15/8
Opposite = 15
Adjacent = 8
Hypotenuse = c
c^2 = opposite^2 + Adjacent^2
c^2 = 15^2 + 8^2
c^2 = 225 + 64
c^2 = 289
sqrt(c^2) = sqrt(289)
c = 17
Find the opposite of B
Adjacent = 12
Hypotenuse = 37
Opposite = b
adjacent^2 + opposite^2 = hypotenuse^2
12^2 + b^2 = 37^2
144 + b^2 = 1369
b^2 = 1369 - 144
b^2 = 1335
b = 35
Definitions
Sin(A) = Opposite / hypotenuse = 15/17
Sin(B) = opposite / hypotenuse = 35/37
Cos(A) = 8/17
Cos(B) = 12/37
Answer
Cos(A + B) = Cos(A)*Cos(B) - Sin(A)*Sin(B)
Cos(A + B) = 8/17 * 12/37 - 15/17*35/37
Cos(A + B) = 96/629 - 525/629
Cos(A + B) = -429/629

i need a box with a square base and an open top that cna hold 500 in^3. what is the least amount of material i can use to build this box
Answers
Answer:
M(x) = 452,56 in
Step-by-step explanation:
The volume of the open box is 500 in³
V = Area of the base times height
V(b) = x² * h where x is the side of the square and h the heigh
Then 500 = x²*h
Total material to use is: material of the base + material of 4 sides
material of the base is x²
material of one side is x*h we have 4 sides then 4*x*h
Total material M(b)
M(b) = x² + 4*x*h
And as h = 500/ x²
M(x) = x² + 4* x* 500/x²
M(x) = x² + 2000/x
Tacking derivatives on both sides of the equation
M´(x) = 2*x - 200/x²
M´(x) = 0 2*x - 200/x² = 0
x³ - 100 = 0
x³ = 100
x = 4,64 in
And By substitution h = 500/x²
h = 500/(4,64)² h = 23,22 in
How do we know that x = 4,64 make V(x) minimum
we get the second derivative
M´´(x) = 2 + 200*2x/ x⁴ = 2 + 400/x³
M´´(x) is always positive
M´´(x) > 0 then M(x) has a minimum for x= 4,64 in
The least amount of material is:
M(x) = x² + 2000/x
M(x) = (4,64)² * 2000/4,64
M(x) = 21,53 + 431,03
M(x) = 452,56 in
