Topford supplies X-Data DVDs in lots of 50, and they have a reported defect rate of 0.5% so the probability of a disk being defective is 0.005. It follows that the probability of a disk being good is 0.995. What is the probability of getting at least one defective disk in a lot of 50?
Answers
The probability of getting at least one defective disk in a lot of 50 is 0.2217.
What is probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.
Given that,
P (defective disc) = 0.005
P (non-defective) = 1 - 0.005 = 0.995
Now,
P(Getting one defective) = 1 - P(getting 50 non -defective)
= 1 - (0.995)^(50)
= 1- 0.7783
= 0.2217
Hence, the probability of getting at least one defective disk in a lot of 50 is 0.2217.

The number of salespeople assigned to work during a shift is apportioned based on the average number of customers during that shift. Apportion 21 salespeople using Hamiltons method given the information below
Answers
Using Hamilton's method of apportioning, 21 salespeople can be assigned in the table in the following order:
2, 5, 6, 8.
What do you mean by Hamilton's method of apportioning?The approach that now bears his name was first proposed by Alexander Hamilton. Congress endorsed his approach in 1791, but President Washington rejected it. Later, in 1852, it became widely used until 1911. He starts by calculating the precise number of items that each group needs.
Since in the interested question it's about salesperson assigned, we’ll use the language of shift and hours, so we can determine how many salespersons each shift should get.
Now total no. of customers given = 125 + 305 + 439 + 515
= 1375
Now total no of salesperson available = 21.
So, the divisor = 1375/21
= 65.47
Now using Hamilton's method when we divide the average customers per shift by the divisor, we get the no. of salesperson assigned.
So, the salesperson assigned are:
Morning = 125/65.47
= 2
Midday = 305/65.47
= 5
Afternoon = 430/65.47
= 6
Evening = 515/65.47
= 8 (Decimals rounded according to Hamilton's principle)

a blueprint of a house has a scale of 2.5 in:5 feet. would a pool table that is 8 by 6 feet fit in a space that has drawing dimensions of 4 inches and 5.2 inches? if so, how much space will remain after the table is put in the room?
Answers
Answer:
yes it will fit; there would be 35.2 sf remaining
Step-by-step explanation:
Find the dimensions of the table in inches:
2.5/5 = x/6
x = 3 in
2.5/5 = x/8
x = 4 in
Scaled table area = (3 in)(4 in) = 12 in²
Scaled room area = (4 in)(5.2 in) = 20.8 in²
12 < 20.8, Therefore, the table would fit.
How much room is left over:
Find the room dimensions in feet.
2.5/5 = 4/x
x = 8 ft
2.5/5 = 5.2/x
x = 10.4 ft
Room area = (8)(10.4) = 83.2 sf
Table area = (8)(6) = 48 sf
83.2 - 48 = 35.2 sf space would remain

The statement that proves that there is a unique element x such that P(x) is true is: c) 3x(P(x) & Ay(P(y) --> x = y)).
What is probability?The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms.
Here,
In this statement, the quantifier "3x" says that for every element x, and the condition "P(x)" says that x satisfies a certain property. The statement "Ay(P(y) --> x = y)" says that for every other element y, if y also satisfies the property, then it must be equal to x. Hence, if there is a unique element x such that P(x) is true, then this statement is true.
Option (a) says that for every element y, P(y) is equivalent to y = x, but this statement alone does not imply that there is only one element that satisfies P(x).
Option (b) says that for every element x, if P(x) is true, then there is no other element y that also satisfies P(y) and is not equal to x. However, this statement alone does not imply that there exists an element x that satisfies P(x).
The following assertion establishes that there is a unique element x such that P(x) is true: c) 3x(P(x) & Ay(P(y) --> x = y)).

D = {(-1,0), (1, 1), (7,5), (9,6)}
Answers
The ordered pairs that represent the linear function is Option A, B and C.
What is linear function?A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph. If the function has more variables, they should all be constants or known variables in order for the function to continue to function as a linear function.
To determine which ordered pairs represent a linear function we use the equation of slope.
The slope is given as:
m = (y2 - y1) / (x2 - x1)
Option A:
m = (5 - 8) / (-4 + 8) = -3 / 4
m = (2 - 5) / (0 + 4) = -3/ 4
The slopes between the consecutive points are same hence option A represents a linear equation.
Similarly, for option B:
m = (1 + 2) / (2 + 1) = 1
m = (4 - 1) / (5 - 2) = 1
Option B is correct.
Option C:
m = (5 - 8) / (1 + 2) = -3 / 3 = -1
m = (2 - 5)/ (4 - 1) = -1
Option C is correct.
Option D:
m = (1- 0)/ (1 + 1) = 1/2
m = (5 - 1) / (7 - 1) = 4 / 6 = 2/3
Option D is incorrect.
Hence, the ordered pairs that represent the linear function is Option A, B and C.

QUESTION 7 A family moved to Orlando, FL and bought a home. They paid $350,000 for their house. In their neighborhood the mean price of a home is $375,000 with a standard deviation of $7,500. Calculate the z-score for the price of their home and indicate if the price they paid for their home usual or unusual. Choose one • 10 points The z-score is 3.333 and it is usual The z-score is -3.333 and it is usual The z-score is 3.333 and it is unusual The z-score is -3.333 and it is unusual
Answers
Step-by-step explanation:
The z-score for the price of the family's home can be calculated as follows:
z = (350,000 - 375,000) / 7,500 = -3.333
A negative z-score indicates that the value is below the mean. Therefore, the price the family paid for their home is lower than the average price of homes in their neighborhood, so it can be considered unusual.
So, the answer is: The z-score is -3.333 and it is unusual.
If bolt thread length is normally distributed, what is the probability that the thread length of a randomly selected bolt is farther than 2. 5 standard deviations from its mean value.
Answers
The probability that the thread length of a randomly selected bolt is farther than 2. 5 standard deviations from its mean value is 0.62%.
If the thread length of bolts is normally distributed, then we can use the concept of probability to determine the probability that the thread length of a randomly selected bolt is farther than 2.5 standard deviations from its mean value.
This can be calculated using the area under the normal curve.
Specifically, the area to the right of 2.5 standard deviations is 0.0062, meaning that there is only a 0.0062 probability (or 0.62%) that the thread length of a randomly selected bolt is farther than 2.5 standard deviations from its mean value

now, keeping in mind that x-axis is the seconds, however a parabola could go into the 2nd, 3rd and 4th Quadrants, but for this case, we only need it in the 1st Quadrant, because the seconds are positive, it begins at 0 seconds and goes up, then down and hits the ground later on when f(x) = 0, hmmm when is that?

now, both values are valid for "x", however for this specific case, we can't have negative seconds, so the negative value won't work. So the appropriate domain or values for "x" are from 0 to 4, the object went up and down in 4 seconds flat.

the two numbers.
First complete the equations below, where x stands for
the first number and y stands for the second number.
2x + y = [?]; y = []x - [ ]
Answers
2x + y = 18
y = 4x - 12
We can substitute the second equation into the first one:
2x + (4x - 12) = 18
Combining like terms:
6x - 12 = 18
Adding 12 to both sides:
6x = 30
Dividing both sides by 6:
x = 5
Now that we have x, we can substitute it back into one of the equations to find y:
y = 4x - 12
y = 4 * 5 - 12
y = 20 - 12
y = 8
The two numbers are 5 and 8

2) City A and City B have decreased growth in population. Write an exponential function to represent City B’s population, y, based on the number of years that pass, x, after a period of exponential decline.
3) Explain the similarities and differences between your GROWTH equations and your DECAY equations.
Answers
y = A * b^x
where A is the population at time x = 0, b is the growth factor, and x is the number of years that have passed. The growth factor, b, is greater than 1.
2) An exponential function to represent City B's population with decreased growth can be written as:
y = A * b^(-x)
where A is the population at time x = 0, b is the decay factor, and x is the number of years that have passed. The decay factor, b, is between 0 and 1.
3) The similarities between the growth and decay exponential functions are that in both equations, the population is a function of time (x) and the exponential function is used to model the change in population over time.
The differences between the growth and decay exponential functions are that the growth function has a growth factor (b) greater than 1, while the decay function has a decay factor (b) between 0 and 1. Additionally, in the growth function, the exponent is positive (x), meaning the population is increasing, while in the decay function, the exponent is negative (-x), meaning the population is decreasing.
You owe $488.32 on your credit card. Because you have not paid your bill on time, you have to add a past due charge of $29, an over limit fee of $50, and a service charge of 11% of the amount owed on the credit card (without the past due charge and over limit fees). If you wish to send a check for the full amount immediately, how much should you write the check for? Round your answer to the nearest cent, if necessary.
