Seventy-two percent of the light aircraft that disappear while in flight in a certain country are subsequently discovered. Of the aircraft that are discovered, 66% have an emergency locator, whereas 80% of the aircraft not discovered do not have such a locator. Suppose a light aircraft has disappeared. (Round your answers to three decimal places.)
a) If it has an emergency locator, what is the probability that it will not be discovered?
b) If it does not have an emergency locator, what is the probability that it will be discovered?
c) If we consider 10 light aircraft that disappeared in flight with an emergency recorder, what is the probability that 7 of them are discovered?
Answers
Answer:
a) 0.105 = 10.5% probability that it will not be discovered if it has an emergency locator.
b) 0.522 = 52.2% probability that it will be discovered if it does not have an emergency locator.
c) 0.064 = 6.4% probability that 7 of them are discovered.
Step-by-step explanation:
For itens a and b, we use conditional probability.
For item c, we use the binomial distribution along with the conditional probability.
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
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.
a) If it has an emergency locator, what is the probability that it will not be discovered?
Event A: Has an emergency locator
Event B: Not located.
Probability of having an emergency locator:
66% of 72%(Are discovered).
20% of 100 - 72 = 28%(not discovered). So
[tex]P(A) = 0.66*0.72 + 0.2*0.28 = 0.5312[/tex]
Probability of having an emergency locator and not being discovered:
20% of 28%. So
[tex]P(A cap B) = 0.2*0.28 = 0.056[/tex]
Probability:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.056}{0.5312} = 0.105[/tex]
0.105 = 10.5% probability that it will not be discovered if it has an emergency locator.
b) If it does not have an emergency locator, what is the probability that it will be discovered?
Probability of not having an emergency locator:
0.5312 of having. So
[tex]P(A) = 1 - 0.5312 = 0.4688[/tex]
Probability of not having an emergency locator and being discovered:
34% of 72%. So
[tex]P(A \cap B) = 0.34*0.72 = 0.2448[/tex]
Probability:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.2448}{0.4688} = 0.522[/tex]
0.522 = 52.2% probability that it will be discovered if it does not have an emergency locator.
c) If we consider 10 light aircraft that disappeared in flight with an emergency recorder, what is the probability that 7 of them are discovered?
p is the probability of being discovered with the emergency recorder:
0.5312 probability of having the emergency recorder.
Probability of having the emergency recorder and being located:
66% of 72%. So
[tex]P(A \cap B) = 0.66*0.72 = 0.4752[/tex]
Probability of being discovered, given that it has the emergency recorder:
[tex]p = P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.4752}{0.5312} = 0.8946[/tex]
This question asks for P(X = 7) when [tex]n = 10[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 7) = C_{10,7}.(0.8946)^{7}.(0.1054)^{3} = 0.064[/tex]
0.064 = 6.4% probability that 7 of them are discovered.

Because there are lengths going from 0 to 1, the lines must mean either decimals or fractions (we'll use fractions for this.)
1. There are twelve lines from 0 and 1, which we can use as the denominator for our fraction. This means the length of each line is 1/12.
2. In order to find where K's point is at, we simply need to count until we get to it. After counting, I see that K is on point 8/12, which we can simplify to get a smaller number. If we simplify once, we get 4/6, which we can again simplify to get 2/3. This gives us the answer K is on point 8/12 or 2/3.

Step-by-step explanation:
this is a 45-45-90° Δ and the leg to hypotenuse ratio is always 1 : [tex]\sqrt{2}[/tex]
so we can set up a proportion:
20 / [tex]\sqrt{2}[/tex] = x / 1

x = 20 / [tex]\sqrt{2}[/tex], which simplifies to 10[tex]\sqrt{2}[/tex] if you rationalize the denominator

was the predicted profit in year 10?
A. $44.36 million
B. $10 million
C. $15 million
D. $13.76 million
Answers
Answer:
D. $13.76 million is the correct answer :)
Step-by-step explanation:
The solution is, $13.76 was the predicted profit in year 10.
Here, we have,
Given : the equation is,
y=-0.34x^2 + 4.43x + 3.46.
To Find : Using the quadratic regression equation, what was the predicted profit in year 8
Solution :
y=-0.34x^2 + 4.43x + 3.46.
Where y is profit and x is year
Substitute x = 10
y=-0.34* 10^2 + 4.43*10+ 3.46.
or, y = 13.76
So, Option D is true
Hence the predicted profit in year 10 is $13.76.

1. x is greater to or equal to 99
2. x is greater to or equal to 100
3. x is greater to or equal to 133
4. or x is greater to or equal to 134
Answers
Given:
Selling price of each CD = $5.00
Cost price of each CD = $1.25
Number of CDs ordered = 300
Profit must be at least $500.
To find:
The number of CDs needs to sell.
Solution:
Let n be the number of CDs needs to sell.
Selling price of each CD = $5.00
Selling price of x CDs = $5n
Cost price of each CD = $1.25
Cost price of 300 CDs = 300×$1.25
= $375
We know that,
[tex]Profit=S.P.-C.P.[/tex]
[tex]Profit=5n-375[/tex]
Profit must be at least $500. it means profit must be greater than or equal to $500.
[tex]5n-375\geq 500[/tex]
[tex]5n\geq 500+375[/tex]
[tex]n\geq \dfrac{875}{5}[/tex]
[tex]n\geq 175[/tex]
All options are incorrect. The required inequality is n is greater than or equal to 175.

step 2 Multiply both numerators

step 3 Multiply both denominators
= 8 x 1
= 8
step 4 Use above values of step 2 & 3, and rewrite as below
= 28/8
Thus, 28/8 is equivalent fraction for 7/8 times of 4, and its simplified term is 7/2.
The expression (7/8) x (4/7) simplified to its simplest form is 1/2.
To simplify the expression (7/8) x (4/7), you can multiply the numerators together and the denominators together, and then simplify the resulting fraction if possible.
(7/8) x (4/7)
= (7 x 4) / (8 x 7)
= 28 / 56
To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 28:
28 / 56
= (28 ÷ 28) / (56 ÷ 28)
= 1 / 2
Therefore, (7/8) x (4/7) simplified to its simplest form is 1/2.

Find the sum of the first 35 terms of the following series, to the nearest integer.
3, 11, 19...
Answers
=======================================================
Explanation:
The sequence {3,11,19,...} is arithmetic since we are adding 8 to each term to get the next one
3+8 = 1111+8 = 19etc. This means the common difference is d = 8.
The first term is a = 3
Let's use this formula
S = n*(2*a + d(n - 1) )/2
so we can find the sum of the first n terms. In this case, n = 35
So,
S = n*(2*a + d(n - 1) )/2
S = 35*(2*3 + 8(35 - 1) )/2
S = 35*(6 + 8(34))/2
S = 35*(6 + 272)/2
S = 35*(278)/2
S = 35*139
S = 4865
[tex]4865[/tex] is the the sum of the first [tex]35[/tex] terms of the following series [tex]3, 11, 19...[/tex]
What is arithmetic sequence?
An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2
The sequence [tex]{3,11,19,...}[/tex] is arithmetic since we are adding [tex]8[/tex] to each term to get the next one as shown below:
[tex]3+8 = 11\\11+8 = 19[/tex]
This means the common difference is [tex]d = 8.[/tex]
The first term is [tex]a = 3[/tex]
Number of terms [tex]=n=35[/tex]
Sum of the series
[tex]=\frac{n}{2} (2a+(n-1)d)[/tex]
[tex]=\frac{35}{2} (2[/tex]×[tex]3+34[/tex]×[tex]8)[/tex]
