7. If U= {2, 4, 6, 8, 10, 12, 14, 16} and
A = {6, 10, 14}, what is A'?
The compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.
We are given the universal set as:
U = {2, 4, 6, 8, 10, 12, 14, 16}
We are also given that set A is:
A = {6, 10, 14}
We need to find A'
For this, we will subtract set A from the universal set, U.
So, we get that:
A' = U - A
A' = {2, 4, 6, 8, 10, 12, 14, 16} - {6, 10, 14}
Solving the expression, we get that:
A' = {2, 4, 8, 12, 16}
Therefore, we get that, the compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.

The probability that a customer ordered a large given that he or she ordered a hot drink is 88 % .
What is Probability ?
The probability is equal to the variety of possible outcomes. the total number of outcomes that could occur. For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail).The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Probability Formula = f/n
where,
f is the number of times an event occurs
n is the total number of trial
The probability is represented as:
P(Large | Hot)
This is calculated using:
P(Large | Hot) = n(Large and hot)/n(hot)
Using the data on the given table, we have:
P(Large | Hot) = 22/(8 + 12 + 5)
P(Large | Hot) = 0.88
In percentage
P(Large | Hot) = 88%

What is the degree of the polynomial?
Davis is trying to decide between two part time jobs on Saturdays. He could make $16.25 per hour working
at the city's ice arena, but getting to work and back would cost him $7.50 round trip for travel. His other
option is to work as a dog walker in his neighborhood for $12.50 per hour but he can ride his bike or walk
there for free. He estimates he could work up to 7 hours at the arena but up to 10 hours walking dogs. He
always works at least 1 hour if he goes to the arena.
1. Write two different functions that represent Davis's gross wages, where h is the number of
hours Davis works per week, a(h) is his gross wages at the ice arena minus travel expenses, and
d(h) is his gross wages from walking dogs.
1. State the domain and range for each function.
2. If Davis works 1 hour, what would be his gross pay at each job? What if he worked 6 hours?
3. Davis wants to know what his net pay, also called take-home pay, is going to be. Assume that
10.5% of just his paycheck, not his travel expenses, is withheld for taxes at the arena. Because
dog walking is a self-employed activity, Davis estimates he needs to set aside 18% of his income
for taxes. Modify your functions from question 1 to model net pay including these tax
withholdings.
4. State the domain and range for each of these new functions.
1) Two different functions that could represent Davis' gross wages, where h is the number of hours Davis works per week, a(h) is his gross wages at the ice arena minus travel expenses, and d(h) is his gross wages from walking dogs are:
Function A: a(h) = 16.25h - 7.50
Function B: d(h) = 12.50h
2) If Davis works 1 hour, his gross pay at each job is:
1 Hour 6 Hours
a) $16.25 $97.50
b) $12.50 $75
3) To find Davis' net pay after tax, the modified functions in question 1 are as follows:
Function A: a(h) = (16.25h - 7.50)(1 - 0.105)
Function B: d(h) = 12.50h(1 - 0.18)
4) The domain and range for each of these new functions are:

What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
Assets are simply subtracted from liabilities to determine net value. Your money and investments, your home and other properties you own, your automobiles, and any other valuable possessions you own are all considered assets.
Assets = 3,000 + 13,000 + 5,500 + 15,000 + 64,000 + 320,000 + 25,000 + 39,000 = 484500
Liabilities = 500 + 210,000 + 18,000 + 25,000 = 257000
Net worth = Assets - Liabilities
Net worth = $484500- $257000 = $227500
Thus, the net worth of a given family is $227500.

Exponentiation is a mathematical operation denoted by the symbol bn that consists of two numbers, the base b, and the exponent or power n, and is pronounced as "b (raised) to the (power of) n."
What are exponents?Exponentiation is a mathematical operation denoted by bⁿ the symbol bn that involves two numbers, the base b, and the exponent or power n, and is pronounced as "b (raised) to the (power of) n." Exponentiation corresponds to repeated multiplication of the base when n is a positive integer: bⁿ is the product of multiplying n bases:[tex]b^n=\underbrace{b \times b \times \cdots \times b \times b}_{n \text { times }}[/tex]
Typically, the exponent is shown as a superscript to the right of the base. In that case, bⁿ is referred to as "b raised to the nth power," "b (raised) to the power of n," "the nth power of b," "b to the nth power," or simply "b to the nth."Several other properties of exponentiation follow directly from the basic fact stated above that, for any positive integer display style n, display style bⁿ is displayed style n occurrences of display style bb all multiplied by each other. More specifically:[tex]\begin{aligned}b^{n+m} &=\underbrace{b \times \cdots \times b}_{n+m \text { times }} \\&=\underbrace{b \times \cdots \times b}_{n \text { times }} \times \underbrace{b \times \cdots \times b}_{m \text { times }} \\&=b^n \times b^m\end{aligned}[/tex]
For example, the number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as 2³) means: 2 x 2 x 2 = 8.Therefore, exponentiation is a mathematical operation denoted by the symbol bn that consists of two numbers, the base b, and the exponent or power n, and is pronounced as "b (raised) to the (power of) n."

Reason:
If we were asked to compute log(ab), then we could use this log rule
log(ab) = log(a) + log(b)
However, we aren't multiplying the 'a' and b, so we cannot use the log rule above. There's not enough information to be able to compute log(a+b)
Choice C is a trick answer I've seen many students fall for since the erroneous thinking would be log(a+b) = log(a)+log(b) = 1.2+5.6 = 6.8
Answer:
b) Not enough information
Step-by-step explanation:
Given the logs of two values, you want to know the log of their sum.
Rules of logarithmsThe logarithm function cannot be applied to a sum. The purpose of the logarithm function is to turn the log of a product into a sum of logs. The logarithm function cannot be applied to a sum.
The only way to determine the log of the sum is to take the antilogs of the given values, add them, then take the log of the result.
Log(a+b)Assuming the base of the logarithms is 10, using the strategy just described, we can compute ...
log(a +b) = log(10^log(a) +10^log(b)) = log(10^1.2 +10^5.6)
≈ log(15.848932 +398,107.17) ≈ log(398,123.02)
≈ 5.6000173 . . . . using base 10 logs
If these are natural logs, which are also often written as log(x), as well as ln(x), then the log of the sum is about
log(e^1.2 +e^5.6) ≈ 5.6122026 . . . . using base e logs
The short answer is, there is not enough information. (The base of the logarithms must be known.)

An airplane descended 225 m in 10 s. What was the airplanes rate of change in elevation
The rate of change in elevation will be:
R = -225m/10s = -22.5 m/s
The airplaen descends at a rate of 22.5 meters per second.
What was the airplane's rate of change in elevation?The rate in change of the elevation will be given by the quotient between the change in elevation and the time in which that change happens.
Here we know that the airplane descended 225 meters, so the change in elevation is:
C = -225m
And that change happens in 10 seconds, so the rate of change in elevation will be:
R = -225m/10s = -22.5 m/s

Total distance travelled by the honey bee is 4km and honeybee’s displacement is 0
Displacement is defined as the shortest distance travelled by the object.
According to the question we have been given that the honeybee travelled 2km before returning to the hive.
Thus the total distance travelled by the honeybee is = 2 + 2 km
= 4 km
And the honeybee’s displacement = 0
Because the bee has returned to the same from where she had left and displacement is a vector quantity that has magnitude and direction and depends upon the initial and final position. So as the initial and final destination is same for the honeybee. Thus the displacement will be zero.

we have no continuous curve here, the supposed function only consists of a few data pair points. and that is absolutely ok.
any function just maps a set of x (input) values to a set of y (function result) values.
A.
yes, it is a function, because every "used" x value has exactly 1 assigned y value.
when we draw a vertical line and move it across the grid, there are never 2 or more of the points in the line. always only one.
the opposite (every y value has exactly 1 x value as origin) is NOT necessary to be a function. but it would have to be true for the inverse function to be a function too.
B.
the domain is the interval or set of all valid x values.
since we have only single points, it is a set here :
{-4, -3, -2, 0, 2, 3}
C.
the range is the interval or set of all valid y values :
{-3, -1, 0, 2, 3}
D.
as we can see on the chart, the only point with x value = 2 has the y value = -3.
so,
y = -3 when x = 2

5 own = 3 lost
Multiply 2 on both sides
2 x 5 own = 2 x 3 lost
10 own = 6 lost
We have,
16 swims in total.
It can be written as,
10 own = 6 lost

how many times does the digit 9 appear in the counting numbers from 1 to 99?
In the counting of numbers from 2 to 99, the digit 9 appears 20 times.
Listing the Numbers
To identify how many times the digit 9 appears, we can first list the numbers we know have a 9 in them:
9, 19, 29, 39, 49, 59, 69, 79, 89, 99
Although we've identified these numbers, we are not finished. Numbers in the 90s also qualify as digits of 9. Therefore, these numbers also are included:
91, 92, 93, 94, 95, 96, 97, 98
Answer RecapNow that we have all the numbers from 1 to 99 with the digit 9 in them, we can count up how many numbers there are with consideration that the number 99 also has two digits of 9 in it:
[(10 + 8) + 2] = 20
Hence, the digit 9 appears 20 times in the counting numbers from 1 to 99.
Answer:
There are 20 times the digit 9 appears in counting numbers from 1 to 99.
Step-by-step explanation:
To see why this is the case, we can break the counting numbers down into two categories: numbers with a 9 in the units place and numbers without a 9 in the units place.
For the first category, we can count the number of times a 9 appears in the units place by counting from 9 to 99 in increments of 10. There are 10 numbers in this category.
For the second category, we can count the number of times a 9 appears in the tens place by counting from 19 to 99 in increments of 100. There are 10 numbers in this category as well.
Therefore, the total number of times the digit 9 appears in counting numbers from 1 to 99 is 20 times.
