400 wrist watches in a box of 10,000 are defective. If 100 watches are selected at random, find the probability that 50 are defective
Step-by-step explanation:
The probability of selecting a defective watch is 400/10,000 = 2/50.
The probability of selecting 50 defective watches out of 100 selected is given by the binomial distribution:
(100 choose 50) * (2/50)^50 * (1/2)^(100-50) = 0.072.
So the probability that exactly 50 out of 100 selected watches are defective is approximately 0.072.

Imagine you start with $1.00 in a bank account that pays 100% interest per year. If the interest is credited once (annually) at the end of the year, the value of the account at year end will be $2.00. If the interest is credited twice in the year (semi-annually), the interest rate for each 6 months will be 50% (100%/2), so the initial $1 is multiplied by 1.5 twice (1 to include the original principal and .5 to add 50% more), yielding $1.00×1.52= $2.25 at the end of the year. Compounding quarterly yields $1.00×1.254= $2.4414. This formula can be written as: Where n is the number of times that interest is credited or compounded per year. 1. Calculate the value of the $1 investment if the interest is compounded (round to 3 decimal places). Show all work. a. Monthly b. Weekly c. Daily d. 1000 times in a year 2. Is there a big difference between compounding monthly and 1000 times/year? Is this a surprising result to you? Use complete sentences.
The result is the same, $2.7048. This result is not surprising because as the number of compounding periods increases, the difference between the amount after each compounding period becomes smaller and smaller. Eventually, the amount after compounding reaches a limit, which is $2.7048 in this case.
How solve the problem?a. To calculate the value of the investment compounded monthly, the formula to use is:
A = P * (1 + r/m)^(mt)
where P is the principal, r is the annual interest rate (100% in this case), t is the time in years (1 in this case), m is the number of times compounded in a year (12 in this case), and A is the amount after compounding.
A = $1.00 * (1 + 100% / 12)^(12 * 1)
A = $1.00 * (1 + 100% / 12)^12
A = $1.00 * (1.0083)^12
A = $1.0083^12
A = $2.682
b. To calculate the value of the investment compounded weekly, the formula to use is:
A = P * (1 + r/m)^(mt)
where P is the principal, r is the annual interest rate (100% in this case), t is the time in years (1 in this case), m is the number of times compounded in a year (52 in this case), and A is the amount after compounding.
A = $1.00 * (1 + 100% / 52)^(52 * 1)
A = $1.00 * (1 + 100% / 52)^52
A = $1.00 * (1.00192)^52
A = $1.00192^52
A = $2.7005
c. To calculate the value of the investment compounded daily, the formula to use is:
A = P * (1 + r/m)^(mt)
where P is the principal, r is the annual interest rate (100% in this case), t is the time in years (1 in this case), m is the number of times compounded in a year (365 in this case), and A is the amount after compounding.
A = $1.00 * (1 + 100% / 365)^(365 * 1)
A = $1.00 * (1 + 100% / 365)^365
A = $1.00 * (1.00027)^365
A = $1.00027^365
A = $2.7048
d. To calculate the value of the investment compounded 1000 times in a year, the formula to use is:
A = P * (1 + r/m)^(mt)
where P is the principal, r is the annual interest rate (100% in this case), t is the time in years (1 in this case), m is the number of times compounded in a year (1000 in this case), and A is the amount after compounding.
A = $1.00 * (1 + 100% / 1000)^(1000 * 1)
A = $1.00 * (1 + 100% / 1000)^1000
A = $1.00 * (1.001)^1000
A = $1.001^1000

∠XPV = 130°
∠WPZ = 85°
1. Arc YZ is a minor arc.
2. Arc WX is a minor arc.
3. ∠VPZ = 95°
4. Arc VZ is a minor arc.
5. Arc VWX is a major arc.

9. ∠VPX = 130°
10. Arc XVY is a semicircle.
11. Arc XWY is a semicircle.
12. Arc WZX is a major arc.
Step-by-step explanation:
As WV and XY are diameters, and ∠WPX = 50° then according to the vertical angles theorem, ∠YPV = 50°.
As VW is a diameter of circle P, and angles on a straight line sum to 180°:
⇒ ∠WPX + ∠XPV = 180°
⇒ 50° + ∠XPV = 180°
⇒ ∠XPV = 130°
As XY is a diameter of circle P, and angles on a straight line sum to 180°:
⇒ ∠WPZ + ∠ZPY + ∠YPV = 180°
⇒ ∠WPZ + 45° + 50° = 180°
⇒ ∠WPZ + 95° = 180°
⇒ ∠WPZ = 85°
Add the central angles to the given circle diagram (see attachment).
Definition of ArcsMinor arc: An arc whose measure is less than 180°.Note that two-letter arcs might not necessarily be minor arcs if their measure is more than 180°. Therefore, use circle P to double-check each two-letter arc.
Note that three-letter arcs might not necessarily be major arcs if their measure is less than 180°. Therefore, use circle P to double-check each three-letter arc.
As WV and XY are diameters of circle P, when the endpoints of a three-letter arc are the endpoints of one diameter, the arc will be a semicircle.
1. Arc YZ is a minor arc.
2. Arc WX is a minor arc.
3. ∠VPZ = 50° + 45° = 95°
4. Arc VZ is a minor arc.
5. Arc VWX is a major arc: Start at endpoint V, move counterclockwise around the circle through point W through to endpoint X.
6. Arc ZVW is a major arc: Start at endpoint Z, move clockwise around the circle through point V through to endpoint W.
7. Arc YWZ is a major arc: Start at endpoint Y, move clockwise around the circle through point W through to endpoint Z.

What is a Major or Minor Arc?The arcs are defined as follows:
Minor arc: An arc whose measure is less than 180°. Minor arcs are named using the two letters of the endpoints. The two letters can be in any order.Major arc: An arc whose measure is greater than 180°. Major arcs are named using three letters. The two letters at the end of the name are the endpoints of the arc. The middle letter is the name of the point contained in the arc.Semicircle: An arc whose measure is equal to 180°.It is to be noted that two-letter arcs might not necessarily be minor arcs if their measure is more than 180°. Therefore, use circle P to double-check each two-letter arc.
Also, three-letter arcs might not necessarily be major arcs if their measure is less than 180°. Therefore, use circle P to double-check each three-letter arc.
To solve for the arcs:
Given that WV and XY are diameters, and ∠WPX = 50° then according to the vertical angles theorem, ∠YPV = 50°.
As VW is a diameter of circle P, and angles on a straight line sum to 180°:
⇒ ∠WPX + ∠XPV = 180°
⇒ 50° + ∠XPV = 180°
⇒ ∠XPV = 130°
Since XY is a diameter of circle P, and angles on a straight line sum to 180°:
⇒ ∠WPZ + ∠ZPY + ∠YPV = 180°
⇒ ∠WPZ + 45° + 50° = 180°
⇒ ∠WPZ + 95° = 180°
⇒ ∠WPZ = 85°
Given that WV and XY are diameters of circle P, when the endpoints of a three-letter arc are the endpoints of one diameter, the arc will be a semicircle. Thus,
1. Arc YZ is a minor arc.

Find the average rate of change of the function f(x)=9/-3x+4, on the interval [3,5]
The average rate of change of the function f(x)=9/-3x+4, on the interval [3,5] is 1.
What is function?A function is a process or set of instructions that takes inputs, performs a specific task, and produces an output. Functions are key components of programming languages, allowing the coder to create complex commands with simple instructions. For example, a function can be used to add two numbers together or to generate a random number. Functions can also be combined to create more complex sequences of instructions.
The average rate of change of the function f(x)=9/-3x+4, on the interval [3,5] can be determined by taking the difference of the output values of the function at the endpoints of the interval, and then dividing it by the difference of the input values of the interval.
The output of the function at x=3 is f(3)=9/-3*3 +4 = -5,
and the output of the function at x=5 is f(5)=9/-3*5 +4 = -3.
Therefore, the difference of the output values is f(5)-f(3) = -3 - (-5) = 2
The difference of the input values is 5-3 = 2
Therefore, the average rate of change of the function on the interval [3,5] is f(5)-f(3) / (5-3) = 2/2 = 1.
Hence, the average rate of change of the function f(x)=9/-3x+4, on the interval [3,5] is 1.

A series of terms is referred to as a geometric progression if each next term is produced by multiplying each previous term by a fixed amount. (GP), whereas the common ratio is the name given to the constant value. In the case of the GP 2, 4, 8, 16, 32, 64, for instance, the common ratio is 2.
What is the GP equation?The phrase that comes after the previous one in the GP, having a common ratio of r = l/[r(n-1)]. S=a/(1 - r), where 0 r 1, is the sum of infinite, or the sum of a GP with infinite terms.
What does GP number mean?A number progression is said to as a geometric progression if any two consecutive terms is always same.
Hence we have a=3,n=9,r=2
Now [tex]t=ar^n^-^![/tex]
=[tex]3*2^9^-^1[/tex]
=[tex]3*2^8[/tex]
=3×256
=768
∴ The ninth term of the G.P. is 768.

Divide. (40c3+20c2−36c)÷(4c)
Enter your answer in standard form in the box.
The value of the given number after division is 10c² + 5c - 9.
What is division?Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.
Given to divide (40c³ +20c² −36c) ÷ (4c)
dividing each term separately,
40c³/4c + 20c²/4c - 36c/4c
dividing constant by constant and variables by variable,
10c² + 5c - 9
Hence the division is 10c² + 5c - 9.

if the economy is producing 12 units of guns and 4 units of butter, what is the opportunity cost of increasing the production of butter from 4 units to 11 units?
If the economy is producing 12 units of guns and 4 units of butter, the opportunity cost of increasing the production of butter from 4 units to 11 units is 4 units of guns.
What is an opportunity cost?In Economics, an opportunity cost is sometimes referred to as alternative forgone and it can be defined as the value, profit or benefits that are given up and forfeited by an individual or business organization, in order to choose or acquire something that is deemed most significant at a particular point in time.
This ultimately implies that, the opportunity cost of owning or earning a thing is the alternative that is foregone in the attainment or earning of another value, profit or benefits.
Cost increase = 11 units - 4 units = 7 units of butter.
In this context, we can reasonably infer and logically deduce that the opportunity cost of 7 more units of butter would be 4 units of guns.

Suppose that a single die with 19 sides (numbered 1, 2, 3, ... , 19) is rolled once. What is the probability of getting an even number.
Step-by-step explanation:
To find the probability of getting an even number, we need to count the number of even numbers and divide it by the total number of sides of the die:
Number of even numbers = 10 (2, 4, 6, 8, 10, 12, 14, 16, 18, 19)
Total number of sides = 19
P(even number) = Number of even numbers / Total number of sides = 10/19 = 0.526 (or 52.6%)
In a survey, the planning value for the population proportion is p*= 0.25. How large a sample should be taken to provide a 95% confidence interval with a margin of error of 0.06? Round your answer up to the next
whole number.
The sample should be taken to provide a 95% confidence interval is 200.
What is a confidence interval?A confidence interval is made up of the mean of your estimate plus and minus the estimate's range. This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence.
Confidence is another name for probability in statistics.
Given the planning value for the population proportion,
probability, p = 0.25
q = 1 - p = 1 - 0.25
q = 0.75
margin of error = E = 0.06
value of z at 95% confidence interval is 1.96,
the formula for a sample is,
n = (z/E)²pq
n = (1.96/0.06)²*0.25*0.75
n = 200.08
n = 200 approx
Hence sample size is 200.
