In the Olympic Games, Michael Phelps won eight gold medals in swimming. Following are some of the events he won, along with his margin of victory, in seconds
The median margin for victory will be 1.89.
What defines median?The median of the data is the value of the middle observation discovered after the data are organized in ascending order. The median is useful in situations where it is difficult to express anything while taking into account all of the data.
One of the easy to calculate statistical summary metrics is the median. Since it bases its value on the data that is in the middle of a sequence, the median is often referred to as the place average.
Given Data:-
1.89,2.32,0.08,4.74,0.30
Mean margin of victory= 1.866
Median margin of victory= 1.89
So the median margin for victory will be 1.89.

12 People fit comfortably in a 5 feet by 11 feet area. Use this value to estimate the size of a crowd that
is 10 feet deep on both sides of the street along a 3-mile section of a parade route.
Answer:
Step-by-step explanation:
Assuming that there are no sidewalks or other obstructions, the estimated size of the crowd along a 3-mile section of the parade route would be approximately 3,780,400 people. This calculation is based on the assumption that people will be standing shoulder to shoulder and that each person will take up an area of 5 feet by 11 feet. This would mean that for each mile of the parade route, there would be 1,260,800 people standing (12 people x 10 feet x 5280 feet). Multiplying this by 3 gives us 3,780,400 people.
Answer:
12 people fitting in an area of 5*5 = 25 ft². Area of the street: 3 miles = 3*5280 ft = 15840 ft 25 feet on both sides. So, the total area in which the crowd is sparsed is: A = 15840*25*2= 792000 ft². Now we apply the ratio: People over area. Applying cross multiplication: 25x = 12*792000 x = (12*792000)/25 x = 380160

To order tickets online to a hockey game, there is a processing fee plus the cost per ticket. The cost for 5 tickets is $174.45. The cost for 8 tickets is $271.95. Write and solve a linnear equation to find the total cost to order 12 tickets.
The linear equation for this situation is ax + y = Total cost, where is no. of ticket, x = $32.5, is cost of ticket and y = $11.9 is processing fee.
What is linear equation?A linear equation is an algebraic equation where the highest exponent of the variable is one. There are linear equations with one, two, or three variables, but not all linear systems have three equations. Typically, a system of linear equations has a single solution, but occasionally there is no solution or an infinite number of solutions.
A relationship in which the value of one variable, say "x," depends on the value of the other variable, say "y," is described by a two variables linear equation. A linear equation's graph will be a straight line if there are only two variables.
Given that cost for 5 tickets is $174.45
Let x be the cost of each ticket and y be the processing fee
5x + y = 174.45
And for the cost for 8 tickets is $271.95
8x + y = 271.95
Subtract the terms
8x + y = 271.95
- 5x + y = 174.45
3x + 0 = 97.5
If 3x = 97.5
Then,
x = 97.5/3
x = 32.5
Each ticket costs $32.5 then processing fees
5(32.5) + y = 174.45
y = 174.45 - 162.5
y = 11.95
8(32.5) + y = 271.95
y = 271.95 - 260
y = 11.95
Thus, The linear equation for this situation is ax + y = Total cost, where is no. of ticket, x = $32.5, is cost of ticket and y = $11.9 is processing fee.

4. The 92 million Americans of age 50 and over control 50% of all discretionary income. AARP estimates that the average annual expenditure on restaurants and carryout food was $1,873 for individuals in the age group. Suppose this estimate is based on a sample of 80 persons and that the sample standard deviation is $550. a. At 95% confidence, what is the margin of error? b. What is the 95% confidence interval for the population mean amount spent on restaurants and carryout food? c. What is your estimate of the total amount spent by Americans of age 50 and over on restaurants and carryout food? d. If the amount spent on restaurants and carryout food is skewed to the right, would you expect the median amount spent to be greater than or less than$1,873?
a) The margin of error for the 95% confidence interval is given as follows: $122.4.
b) The 95% confidence interval for the population mean amount spent on restaurants and carryout food is given as follows: ($1,750.6, $1,995.4).
c) The estimate of the total amount spent by Americans of age 50 and over on restaurants and carryout food is between $161,055,200,000 and $183,576,800,000.
d) As the distribution os skewed to the right, the median would be expected to be less than the mean.
What is a t-distribution confidence interval?The t-distribution is used when the standard deviation for the population is not known, and the bounds of the confidence interval are given according to the following rule:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
The margin of error is then defined as follows:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]
In which the variables of the equation are presented as follows:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 80 - 1 = 79 df, is t = 1.9905.
The parameters for this problem are given as follows:
[tex]\overline{x} = 1873, s = 550, n = 80[/tex]
Hence the margin of error is of:
[tex]M = 1.9905 \times \frac{550}{\sqrt{80}} = 122.40[/tex]
Considering the sample mean and the margin of error, the bounds of the confidence interval are given as follows:
Lower bound: 1873 - 122.40 = $1,750.6.Upper bound: 1873 + 122.40 = $1,995.4.Considering the bounds of the confidence interval and the population of 92 million, the bounds of the estimate of the total amount are given as follows:

How can you write an equation to represent this problem for any number of guards?
A man entered an orchard through 7 gates and picked some apples. When he left, he gave the first guard half his apples and 1 apple more. To the second guard he gave half his remaining apples and 1 more. He did the same to each of the remaining five guards and left the orchard with 1 apple. How many apples did he gather in all?
Answer:
Step-by-step explanation:
This problem can be represented by the equation: x + (x/2 - 1) + (x/4 - 1) + (x/8 - 1) + ... + (x/128 - 1) + 1 = x, where x is the total number of apples gathered.
This equation represents the process described in the problem, where the man gives half of his remaining apples (x/2, x/4, x/8, etc.) to each guard, minus 1 apple each time, until he is left with 1 apple.

weight of her purchases was 7 1/2pounds. How
much did the bag of grapefruit weigh?
Using the mathematical operations of addition and subtraction, the weight of the bag of grapefruit is 3¹¹/₁₆.
What are the mathematical operations?The basic mathematical operations we have studied so far include addition, subtraction, division, and multiplication.
In addition operation, two or more addends are added to obtain a result known as the sum or total.
Using subtraction operation, the minuend, subtrahend, and difference are the major parts, including the subtraction operator (-).
There are two ways of solving this problem, we can add the fractional weights of apples and bananas and subtract the sum from the total weight of fruits Lynne bought.
We can also subtract each fractional weight from the total weight of fruits to arrive at the fractional weight of the bag of grapefruit.
The total weight of Lynne's purchases = 7¹/₂ pounds
The weight of apples = 1⁵/₈ pounds
The weight of bananas = 2³/₁₆ pounds
The weight of grapefruit = x
= 7¹/₂ - 1⁵/₈ - 2³/₁₆
= 3¹¹/₁₆
Add fractional weights:
1⁵/₈ + 2³/₁₆ = 3¹³/₁₆

The sum of the page numbers on the facing pages of a book is 553. Find the smaller page number.
Answer: To solve this problem, we can use algebra. Let x be the smaller page number. Then, the larger page number is x + 1, since the pages are facing each other. We know that the sum of these two numbers is 553, so we can set up the equation:
x + (x+1) = 553
Next, we will solve for x by combining like terms:
2x + 1 = 553
Now we will subtract 1 from both sides of the equation:
2x = 552
Finally, we will divide both sides by 2:
x = 276
So the smaller page number is 276.

Answer:
The simplest algorithm (a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.) to find the prime factors of a number is to keep on dividing the original number by prime factors until we get the remainder equal to 1. For example, by prime factorizing the number 30 we get, 30/2 = 15, 15/3 = 5, and 5/5 = 1. Since we received the remainder, it cannot be further factorized.

The x-intercepts and the y-intercept of the cubic function f(x) = x³ - 9·x² + 20·x - 12 for which (x - 6) is a factor are;
The x-intercepts are; (6, 0), (2, 0), and (1, 0)The y-intercepts of the function is the point (0, -12)What is a function?A function is a rule that uniquely maps each value from the set of input variables to exactly one value in the set of the output variables.
The specified cubic function is; f(x) = x³ - 9·x² + 20·x - 12
A factor of f(x) = x - 6
The x-intercepts are the points on the graph of the function, where the value of the function, f(x) = 0, which are found as follows;
At the x-intercept, f(x) = x³ - 9·x² + 20·x - 12 = 0
x³ - 9·x² + 20·x - 12

The other factor of the cubic function is; x² - 3·x + 2
x² - 3·x + 2 = (x -2)·(x - 1)
Therefore;

In interest rate 6% in 2500$ in year when go to investment at the end how many amount of 3 yrs and 5 months in simple interest ?
Answer: So, after 3 years and 5 months, the total amount of simple interest earned on an investment of $2500 at a 6% interest rate would be $525.
Step-by-step explanation:
To calculate the simple interest on an investment of $2500 at a 6% interest rate for 3 years and 5 months, you would use the formula:
Simple Interest = (Principal x Interest Rate x Time in Years)
In this case, the time in years would be 3.5 (3 years and 5 months)
Simple Interest = (2500 x 0.06 x 3.5) = $525
So, after 3 years and 5 months, the total amount of simple interest earned on an investment of $2500 at a 6% interest rate would be $525.
