Function in mathematicsIn mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Functions were originally the idealization of how a varying quantity depends on another quantity. For example, the position of a planet is a function of time. Historically, the concept was elaborated with the infinitesimal calculus at the end of the 17th century, and, until the 19th century, the functions that were considered were differentiable (that is, they had a high degree of regularity). The concept of a function was formalized at the end of the 19th century in terms of set theory, and this greatly enlarged the domains of application of the concept.

brass is an alloy created using $80\%$ copper and $20\%$ zinc. if henri's brass trumpet contains $48$ ounces of copper, how many ounces of zinc are in the trumpet?
Henry's trumpet which is made of an alloy brass contains 9.6 ounces of zinc.
Brass is an alloy created using 80% copper and 20% zinc, which means that for every 100% of the alloy, 80% is copper and 20% is zinc.
If henry's trumpet contains 48 ounces of copper, we can use the proportion of copper and zinc in the alloy to find the number of ounces of zinc.
First, we can convert the percentage of zinc to a decimal by dividing by 100: 20% = 0.20
Next, we can set up an equation using the proportion of zinc in the alloy to the number of ounces of zinc in the trumpet:
0.20 = x/48 ounces of zinc
To solve for x, we can multiply both sides of the equation by 48:
0.20 * 48 = x
x = 9.6 ounces of zinc
So, Henry's trumpet contains 9.6 ounces of zinc.

The lifetime of a particular type of car tire is normally
distributed. The mean lifetime is 50,000 miles, with a
standard deviation of 5,000 miles. Of a random sample of
15,000 tires, how many of the tires are expected to last for
between 45,000 and 55,000 miles?
0 7,125
o 10,200
o 14.250
14,850
Answer:
To answer this question, we need to use the properties of a normal distribution. So, the answer is b. 10,200
Step-by-step explanation:
The mean and standard deviation serve as the defining characteristics of a normal distribution, a form of probability distribution. The average tire lifespan in this situation is 50,000 miles, with a standard variation of 5,000 miles.
The number of tires that should last between 45,000 and 55,000 miles, or the region under the normal distribution curve between these two figures, is what we're looking for. The conventional normal table or a calculator using the inverse cumulative probability function can be used to find this region.
We can standardize the values by using the standard normal table, which is (X-mean)/standard deviation.
(45,000-50,000) / 5,000 = -1
(55,000-50,000) / 5,000 = 1
The area between -1 and 1 standard deviation from the mean is about 0.6826, which is the proportion of the tires that are expected to last between 45,000 and 55,000 miles.
To find the number of tires, we can multiply the proportion by the sample size (15,000)
0.6826 * 15,000 = 10,200
So, the answer is b. 10,200

The probability that a randomly selected customer likes hot or iced coffee is 0.83.
What is probability?
To find the probability that a randomly selected customer likes hot or iced coffee, we need to add the probability of liking hot coffee and the probability of liking iced coffee, while subtracting the probability of liking both (since we don't want to count those customers twice).
So, P(H or I) = P(H) + P(I) - P(H and I)
We are given that P(H) = 0.75, P(I) = 0.30, and P(H and I) = 0.22 (from the venn diagram).
Therefore, P(H or I) = 0.75 + 0.30 - 0.22 = 0.83
So the probability that a randomly selected customer likes hot or iced coffee is 0.83.
Therefore, the answer is 0.83.

The common difference is an important part of any arithmetic sequence. It is the number that is added to each term in the sequence to generate the next term. For example, the first two terms of the sequence are 5 and 9. The common difference of 4 is added to the first term (5) to get the second term (9). The common difference is then added to the second term (9) to get the third term (13), and so on. This is how the sequence is generated.
The common difference is an important tool for analyzing the behavior of an arithmetic sequence. Knowing a common difference allows you to determine the nth term of the sequence, as well as the sum of the first n terms. It also helps you to identify patterns in the sequence and make predictions about future terms. Knowing a common difference is an essential part of analyzing arithmetic sequences.

Which store has the better buy? explain your answer.two stores are selling candy for valentine's day. store a sells 2 1/4 lbs of candy for $13.50. store b sells 1 1/2 lbs of candy for $15.75.
Comparing the value of 1 lbs of the candy we observe that, store A sells the candy at a much cheaper price and hence it has the better buy.
What are mixed fractions?A mixed fraction is one that is represented by both its quotient and remainder. A mixed fraction is, for instance, 2 1/3, where 2 is the quotient and 1 is the remainder. An amalgam of a whole number and a legal fraction is a mixed fraction.
Given the number of candies the store sells for a given amount:
Store A:
2 1/4 lbs candy = $13.50
1 lbs candy = x
[tex]x = \frac{13.50}{\frac{9}{4} } \\\\x = \frac{(13.50)(4)}{9}\\ \\x=6[/tex]
Hence, store A sells 1 lbs of candy for $6.
Store B:
1 1/2 lbs candy = $15.75
1 lbs candy = y
[tex]y = \frac{15.75}{\frac{3}{2} } \\\\y = \frac{(15.75)(2)}{3}\\ \\y = 10.5[/tex]
Store B sells 1 lbs of candy for $ 10,5.
Comparing the value of 1 lbs of the candy we observe that, store A sells the candy at a much cheaper price and hence it has the best buy.

which expression evaluates to true if and only if the units digit of an integer variable x is less than 6
The units digit of an integer every square of an integer ends with (=has a units digit) 0, 1, 4, 5, 6, or 9.
This question can be answered in a variety of ways. Finding squares with the unit digits 0, 4, 5, and 6 is one way to demonstrate by means of elimination that the answer must be 2. The reason this method works is that you're presuming one of the answers to this specific multiple-choice question is true, but it's not actually that fulfilling.
A more effective method is to note that any number has the form (10m+i) such that 0i9. By squaring, you may determine exactly which numbers are feasible units digits in a square by getting 100m2+20mi+i2, etc. in turn.
Every square of an integer should have the units digit (0, 1, 4, 5, 6, or 9) as its final value.

At what point does the curve have maximum curvature? y = 9 ln(x) (x, y) = What happens to the curvature as x rightarrow infinity? k(x) approaches_______________as x rightarrow infinity.
The point of maximum curvature of the curve y = 9 ln(x) occurs when the second derivative of the curve is equal to zero, which is when x = e. At this point, the curvature of the curve is equal to k(x) = 9/e^2.
What is infinity?Infinity is a concept used to describe something that is limitless or without end. It is typically used to describe a quantity, such as an infinite number of objects or an infinite amount of time. It is also used to describe the concept of something that is boundless or has no boundaries. Infinity is an abstract concept and is not considered a number or a measurement.
As x rightarrow infinity, the value of k(x) approaches zero, because the second derivative of the curve approaches zero. Therefore, k(x) approaches zero as x rightarrow infinity.

i don't know the answer can someone help me answer it
Answer:
A. We can write a function to represent the cost of each quote using the information provided.
For Decks and More:
C(h) = 1800 + 70h
Where C is the cost and h is the number of hours of labor.
For Just Decks:
C(h) = 2000 + 50h
Where C is the cost and h is the number of hours of labor.
B. To determine which company Aaron should use, we need to substitute the estimated number of hours into the functions for both companies and compare the total costs.
For Decks and More:
C(18) = 1800 + 70(18) = 1800 + 1260 = 3060
For Just Decks:
C(18) = 2000 + 50(18) = 2000 + 900 = 2900
Since Just Decks quote is cheaper, Aaron should use Just Decks.
Sam has a goal of walking (3)1/2 miles by the end of the day. He walks (1)1/8 miles before lunch and 3/4 miles after resting. What is the remaining distance, in miles, that same needs to walk to reach his goal?
Since the remaining distance is negative, it implies that Sam has already exceeded his goal distance. Therefore, he doesn't need to walk any further to reach his goal.
To find the remaining distance that Sam needs to walk to reach his goal of (3)1/2 miles, we need to subtract the distance he has already walked from his goal distance.
Sam walks (1)1/8 miles before lunch and 3/4 miles after resting. To calculate the total distance he has walked, we add these two distances:
Total distance walked = (1)1/8 + 3/4
To add these fractions, we need to find a common denominator, which is 8 in this case
Total distance walked = (9/8) + (6/8)
= 15/8
= 1 (7/8)
Now, we subtract the total distance walked from Sam's goal distance:
Remaining distance = (3)1/2 - 1 (7/8)
To subtract fractions, we also need a common denominator. The common denominator is 2 in this case:
Remaining distance = (6/2 + 1/2) - (15/8)
= (12/8 + 1/8) - (15/8)
= 13/8 - 15/8
= -2/8
= -1/4

Answer:
1a. x = 0.08; y = 0.03; z = 0.17
1b. P(B) = 0.25
Step-by-step explanation:
Given a Venn diagram with some numbers filled in, you want to find the missing numbers given that the probability of at least one is 0.92, and of exactly one is 0.70.
How to solveThe missing values are found by understanding the given information and what that means in relation to the diagram.
At least oneThe total area enclosed by the circles is the probability of "at least one." The total probability represented by the entire diagram is 1, so that means ...
x = 1 - 0.92 = 0.08 . . . . . . . area not in any circle
It also means that ...
0.26 +0.05 +y +z +0.41 = 0.92 . . . . . . . area enclosed by circles
y + z = 0.20 . . . . . . . . . . . . . . . . . subtract 0.72
Exactly oneThe probability of exactly one is the sum of areas inside exactly one circle:
0.26 +y +0.41 = 0.70
y = 0.03
Using this with the above equation in y and z, we find ...
z = 0.20 -y = 0.17
BandicootsThe area inside circle B is ...
0.05 +y +z = 0.05 +0.20 = 0.25
The probability a contributor sponsors Bandicoots Unbanned is 0.25.
