Answer:
Given : A bag contains 30 lottery balls numbered 1-30 a ball is selected replaced then another is drawn.
To find : Each probability
1) p ( and even,then odd )
2) p ( 7, then a number greater than 16)
3) p ( a multiple of 5, then a prime number )
4) p ( two even number )
Solution :
[tex]\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total number of outcome}}[/tex]
1) There are 15 even numbers and 15 odd numbers.
Probability of getting even first then odd is
[tex]\text{P(even,then odd)}=\frac{15}{30}\times\frac{15}{30}[/tex]
[tex]\text{P(even,then odd)}=\frac{225}{900}=\frac{1}{4}[/tex]
2) Number greater than 16 out of 30 are 14.
Probability of getting 7 first then a number greater than 16 is
[tex]\text{P(7, then a number greater than 16)}=\frac{1}{30}\times\frac{14}{30}[/tex]
[tex]\text{P(7, then a number greater than 16)}=\frac{14}{900}=\frac{7}{450}[/tex]
3) Multiple of 5 - 5,10,15,20,25,30=6
Prime numbers - 2,3,7,9,11,13,17,19,23,29=10
Probability of getting a multiple of 5, then a prime number is
[tex]\text{P(a multiple of 5, then a prime number )}=\frac{6}{30}\times\frac{10}{30}[/tex]
[tex]\text{P(a multiple of 5, then a prime number )}=\frac{60}{900}=\frac{1}{15}[/tex]
4) There are 15 even numbers.
Probability of getting two even number is
[tex]\text{P( two even number)}=\frac{15}{30}\times\frac{15}{30}[/tex]
[tex]\text{P( two even number)}=\frac{225}{900}=\frac{1}{4}[/tex]

A car rental company has two rental rates. rate 1 is $64 per day pluus $.16 per mile. rate 2 is $128 per day plus $.08 per mile. if you planto rent for one day, how many miles would you need to drive to pay less by taking rate 2
To find when Rate 2 becomes cheaper, we set up an equation based on the rates given and solve for the number of miles. After solving the equation, we find that Rate 2 becomes cheaper after more than 800 miles.
Explanation:The subject of your question is Mathematics, specifically, it's in the domain of linear equations. To find out the number of miles you should drive to pay less by taking rate 2, we need to determine when the total cost of rate 1 is more than rate 2.
Let's call M the number of miles you would drive. The cost for rate 1 would be $64 + $0.16 * M, and the cost for rate 2 would be $128 + $0.08 * M. To find when rate 2 is cheaper, we would set up the equation: 64 + 0.16 * M > 128 + 0.08 * M. By solving this equation for M, we can find the miles where rate 2 becomes cheaper. This equation simplifies to 0.08M > 64 and thus M > 800. So, for more than 800 miles, rate 2 would be the more cost-effective option.

To which subsets of the real numbers does the number 82 belong?
Answer: the number 82 belongs to the following subsets of the real numbers of Natural Numbers (N), Whole Numbers (W), Integers (I), Rational Numbers (Q), Real Numbers (R)
The number 82 belongs to several subsets of the real numbers as given in the following:
1. Natural Numbers (N): The natural numbers are the set of positive integers starting from 1, i.e.,(1, 2, 3,.......). Since 82 is a positive integer, it belongs to this subset.
2. Whole Numbers (W): The whole numbers are the set of non-negative integers, i.e., ( 0, 1, 2, 3,....). Since 82 is a non-negative integer, it belongs to this subset.
3. Integers (Z): The integers include all positive and negative whole numbers, including zero, i.e., ( -3, -2, -1, 0, 1, 2, 3,...). Since 82 is a whole number, it belongs to this subset.
4. Rational Numbers (Q): The rational numbers are numbers that can be expressed as the quotient of two integers [tex]\( \frac{a}{b} \)[/tex], where a and b are integers and [tex]\( b \neq 0 \)[/tex]. Since 82 can be written as [tex]\( \frac{82}{1} \)[/tex], it belongs to this subset.
5. Real Numbers (R): The real numbers include all the rational and irrational numbers. Since 82 is a rational number, it is also a real number.

Find the third derivative of f at x = 0 if the Maclaurin series for f(x) = 1 - 9x + 16x2 - 25x3 + …
The third derivative of f(x) at x=0 is −150.
To find the third derivative of f(x) at x=0, we can utilize the Maclaurin series representation of f(x).
The Maclaurin series expansion of f(x) is given by:
[tex]f(x)=1-9 x+16 x^2-25 x^3+\ldots[/tex]
To find the third derivative, we first need to determine the general expression for the n-th term of the Maclaurin series. The general term of the series is given by:
[tex]f^{(n)}(0) \frac{x^n}{n !}[/tex]
where [tex]f^{(n)}(0)[/tex] represents the n-th derivative of f(x) evaluated at x=0.
Now, let's identify the pattern in the given series:
[tex]f(x)=1-9 x+16 x^2-25 x^3+\ldots[/tex]
The coefficients of the terms seem to be perfect squares of consecutive odd numbers. So, the n-th term of the series can be expressed as [tex](-1)^n \cdot(2 n+1)^2[/tex].
Now, let's find the third derivative of f(x) at x=0:
[tex]\begin{aligned}& f(x)=1-9 x+16 x^2-25 x^3+\ldots \\& f^{\prime}(x)=-9+32 x-75 x^2+\ldots \\& f^{\prime \prime}(x)=32-150 x+\ldots \\& f^{\prime \prime \prime}(x)=-150+\ldots\end{aligned}[/tex]
Now, evaluating f′′′(x) at x=0, we get:
[tex]f^{\prime \prime \prime}(0)=-150[/tex]
So, the third derivative of f(x) at x=0 is −150.
Complete Question:
Find the third derivative of f at x = 0 if the Maclaurin series for:

how does tire size affect the number of rotations? please explain the relationship between tire size and the number of rotations completed in a given distance. Would switching to a bigger or smaller tire cause you to switch your tires sooner? why or why not?
Tire size affects the number of rotations, with larger tires making fewer rotations for a given distance. However, tire size doesn't directly influence when you need to replace your tires, which depends more on usage and wear factors. Changing tire size can impact vehicle performance.
Explanation:The tire size directly affects the number of rotations a wheel makes in traversing a particular distance. A wheel's circumference, which is related to its size, determines how far it will travel in one rotation. A larger wheel will have a greater circumference, meaning it will cover a greater distance in one rotation. Therefore, for a given distance, larger tires will complete fewer rotations than smaller ones.
Switching to a different tire size wouldn't necessarily cause you to have to switch your tires sooner. Tire wear is primarily affected by factors like driving habits, road conditions, tire material, and maintenance, not rotational frequency. However, changing your tire size can affect vehicle mechanics and performance, including speedometer and odometer accuracy, so it's important to consult a professional before making such changes.

what is x???? you HAVE to explain and show for the brainliest!!!!!!
Answer:
x + 64 = 110
x = 46
Step-by-step explanation:
You need to isolate the x, so you need to subtract 64 from 110 ( which is 46 ). By you doing that, you need to now subtract 64 from 64 itself.
Would look like this: x + 64 = 110
- 64 - 64
Which would leave you with x = 46

“When is periodic data useful? Give examples to support your answer.”
Periodic data is useful when analyzing trends or patterns that repeat at regular intervals over time.
Examples include analyzing sales data by month, tracking website traffic by day of the week, or monitoring seasonal fluctuations in temperature.
Example 1: Monthly Sales Data
To illustrate the usefulness of periodic data, let's consider a retail business that tracks its monthly sales over the course of a year. Suppose the sales data for January to December are as follows:
January: $50,000
February: $55,000
March: $60,000
April: $65,000
May: $70,000
June: $80,000
July: $85,000
August: $90,000
September: $95,000
October: $100,000
November: $110,000
December: $120,000
To analyze this periodic data, we can calculate the average monthly sales:
Total Sales = $50,000 + $55,000 + ... + $120,000
= $780,000
Number of Months = 12
Average Monthly Sales = Total Sales / Number of Months
= $780,000 / 12
= $65,000
So, the average monthly sales for this retail business is $65,000.
Periodic data, such as monthly sales figures, allows businesses to identify seasonal trends, peak periods, and areas for improvement. By analyzing this data, businesses can make informed decisions about inventory management, marketing strategies, and resource allocation. In this example, calculating the average monthly sales helps the business understand its typical revenue stream and plan accordingly. Additionally, periodic data analysis enables businesses to compare performance across different time periods and track progress towards goals. Therefore, periodic data is essential for strategic planning and optimizing business operations.
