circular: ≈ 795.77 square feet
square: 625
Step-by-step explanation:
the circular pen would have a larger area.
Solving for the radius, we have:
r = 100 / (2 × 3.14) = 15.92 feet (rounded to two decimal places)
Therefore, the area of the circular pen would be:
Area = πr^2 = 3.14 × (15.92 ft)^2 ≈ 795.77 square feet
For a square pen with side length s, the perimeter is given by:
4s = 100
s = 25
The area of a square pen with side length s is given by:
A = s^2 = 25^2 = 625

what is statistic ?
A statistic is a numerical value or measure that is calculated from a sample of data, and is used to describe or make inferences about a population. Statistics are used in various fields, including business, economics, social sciences, and natural sciences, to analyze data
In the given question,
To test the claim that the percentage of residents who favor construction is more than 49%, we can use a one-sample z-test. The test statistic can be calculated as:
z = (p - P) / √(P * (1 - P) / n)
where:
p = the sample proportion (0.53)
P = the hypothesized population proportion under the null hypothesis (0.49)
n = the sample size (800)
Substituting the given values into the formula, we get:
z = (0.53 - 0.49) / √(0.49 * 0.51 / 800) ≈ 5.19
Rounding the test statistic to two decimal places, we get:
z ≈ 5.19

The percentage increase in the number of water bottles from February to April is 19%.
How to find the percentage increase?A company manufactures water bottles. The list describes the amount of water bottles manufactured in three months.
Therefore,
February: 4100 water bottles
March: 7% more water bottles than in February
April: 500 more water bottles than in march
Therefore,
Number of water bottles in march = 4100 + 7% of 4100
Number of water bottles in march =4100 + 7 / 100 × 4100
Number of water bottles in march = 4100 + 287
Number of water bottles in march = 4387
Hence,
Number of water bottles manufactured in April = 4387 + 500 = 4887
Therefore,
percentage increase from February to April = 4887 - 4100 / 4100 × 100
percentage increase from February to April = 787 / 4100 × 100
percentage increase from February to April = 78700 / 4100

Apply the United States rule to determine the balance at maturity and the total interest paid if the borrower makes two partial payments and the remainder of the loan is paid at maturity.
Principal $1450
Interest Rate % 15.0
Loan Length (Days) 280
Partial Payment
$5800.00
$4350.00
Payment on Day #
112
196
Answer: The United States rule is a method for calculating interest and balances on loans that have partial payments during their term. The rule assumes that each partial payment is applied to the interest first, then to the principal. Here's how to use the United States rule to calculate the balance and interest for this loan:
Calculate the daily interest rate by dividing the annual interest rate by 360 (the number of days in a standard year for most loans).
Daily Interest Rate = 15.0% / 360 = 0.04167%
Calculate the interest due for the first partial payment of $5800 made on day 112. Since this payment is larger than the remaining principal, it will pay off the loan entirely and no interest will accrue beyond this date.
Days between start of loan and first payment = 112 daysInterest due on first payment = (1450 x 0.04167% x 112) = $8.10Principal remaining after first payment = $0.00
Calculate the interest due for the second partial payment of $4350 made on day 196.
Days between first payment and second payment = 84 daysInterest due on second payment = (0 x 0.04167% x 84) = $0.00Principal remaining after second payment = $0.00
Calculate the interest due on the remaining principal at maturity (day 280).
Days between second payment and maturity = 84 daysInterest due at maturity = (0 x 0.04167% x 84) = $0.00
Add up the interest due from each period to get the total interest paid over the life of the loan.
Total interest paid = $8.10 + $0.00 + $0.00 = $8.10
Add up the principal amounts from each payment to get the total amount paid.
Total amount paid = $5800.00 + $4350.00 = $10,150.00
Subtract the total amount paid from the original principal to get the balance at maturity.
Balance at maturity = $1450.00 - $10,150.00 = -$8700.00 (which means the lender owes the borrower this amount)
Therefore, the balance at maturity is -$8700.00 (meaning the lender owes the borrower this amount) and the total interest paid over the life of the loan is $8.10.

Marcus not getting a seat on the school bus is therefore 0.07 or 7% likely as 0.07 percent of people will not receive a seat .
what is probability ?The prospect of an event happening is assessed by probability. It is a number between zero and 1, where 0 denotes an improbable occurrence and 1 denotes a certain occurrence. For instance, if we flip a fair coin, the odds of obtaining heads are 0.5, or 50%, and the odds of receiving tails are also 0.5, or 50%. In each case, there are various ways to compute probability. In general, if an event has n equally possible results and k of them are favourable, the likelihood that the event will occur is: Event P = k/n . All possible outcomes are thought to be equally likely under what is referred to as the classical probability.
given
Simply put, the likelihood that Marcus won't obtain a seat on the school bus is the complement of the likelihood that he will.
By deducting the probability from 1, one can determine the complement of a probability. So:
Chance of not being seated equals one less than the likelihood of being seated.
The likelihood of not getting a seat is equal to 1 - 0.93.
0.07 percent of people will not receive a seat.
Marcus not getting a seat on the school bus is therefore 0.07 or 7% likely as 0.07 percent of people will not receive a seat .

Based on the given function conditions of f(x) , the value of f(7) is equal to -6
To find f(7), we need to determine which function definition to use based on the value of x.
Since x = 7 is greater than 5, we know that we'll be using the third definition of the function: f(x) = -x + 1 for 2 < x ≤ 5.
Therefore, we can substitute x = 7 into the third definition of the function:
f(7) = -7 + 1 = -6
So, f(7) = -6.
In summary, to find f(7), we identified which function definition to use based on the value of x. Since x = 7 is greater than 5, we used the third definition of the function, f(x) = -x + 1 for 2 < x ≤ 5, and found that f(7) = -6.

Solve by using a system of equations.
A goldsmith has two gold alloys. The first alloy is 30% gold; the second alloy is 80% gold. How many grams of each should be mixed to produce 40 grams of an alloy that is 60% gold?
The amount of grams of each alloy that should be mixed to produce 40 grams of an alloy that is 60% gold are 16 grams and 24 grams respectively.
How to write a system of equations to model this situation?In order to write a system of linear equations to describe this situation, we would assign variables to the quantity of first alloy (30% gold) and the quantity of second alloy (80% gold) respectively, and then translate the word problem into a linear equation as follows:
Let the variable y represent the quantity of first alloy (30% gold).Let the variable x represent the quantity of second alloy (80% gold).Therefore, a system of linear equations to describe this situation can be written as follows;
x + y = 40 .....equation 1.
0.3x + 0.8y = 0.6(40) .....equation 2.
From equation 2, we have the following:
0.3x + 0.8y = 24
0.3x + 0.8(x - 40) = 24
0.3x + 32 - 0.8x = 24
-0.5x = -8
x = -8/-0.5
x = 16 grams.
y = 40 - x
y = 40 - 16
y = 24 grams.

If the function g(x) is defined for all real-numbers, then the value of g(-5) is 7/2, g(-2) is -1 and g(-1) is 0.
A piecewise function is a function that is defined by different rules or formulas on different parts of its domain. The piecewise function "g(x)" is given as :
g(x) = {-(1/2)x + 1, for x<-2
= {-(x+1)², for -2≤x≤1
= {4 for x>1
We have to find the value of g(-5) ,g (-2), and g(-1),
For x = -5, the number -5 is less than -2, so the first function "-(1/2)x + 1" will be used,
⇒ g(-5) = -(1/2)(-5) + 1 = 5/2 + 1 = 7/2,
For x = -2, the number -2 lies in the interval "-2≤x≤1", so second function
"-(x+1)²" will be used,
⇒ g(-2) = -(x+1)² = -(-2+1)² = -(-1)² = -1,
For x = -1, the number -1 lies inn the interval "-2≤x≤1", so second function "-(x+1)²" will be used,
⇒ g(-1) = -(x+1)² = -(-1+1)² = -(0)² = 0,

The function f(x) = 2-5* can be used to represent the curve through the points (1, 10), (2, 50), and (3, 250). What is the multiplicative rate of change of the function? 0 2 05 10 • 32
The given function does not represent the curve passing through the given points. The multiplicative rate of change of the function is 5.
What is Curve Line ?A curve is a continuous, smooth line that gradually alters direction. Rather than being straight line that follows a curve may be referred to as a curve line. A curve line can be made by connecting a number of non-straight-line-lying sites. In mathematics, a curve is a geometrical object that can be described by equations, such as parametric or function equations.
The rate of change of a function is the ratio of the change in the output (y) to the change in the input (x). In this case, we can calculate the rate of change between the first two points:
Changing at what rate between (1, 10) and (2, 50)?
Y change = 50 – 10 = 40
Variation in x = 2 - 1 = 1
Rate of change equals change in y/change in x, or 40/1, or 40.
In a similar manner, we can determine how quickly the second and third points will change:
The change between (2, 50) and (3, 250) is as follows:
Changing y by 250 - 50 equals 200
Variation in x = 3 - 2 = 1
Rate of change equals change in y/change in x, which is 200/1, or 200.
Now that we have the second rate of change, we can compute the multiplicative rate of change by dividing it by the first:
Multiplicative rate of change is equal to 200/40, or 5.
The function's multiplicative rate of change is thus 5.

what is the probability that either event will occur
The probability that either event will occur is 7/25
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur. The certainty of an event is 1 which is equivalent to 100% in percentage.
Probability = sample space /Total outcome
P(A or B) = P(A) +P(B) -P(A and B)
The total element = 25+5+15+5 = 50
therefore total outcome = 50
P(A) = 25/50
P(B) = 15/50
P(A and B) = 5/40
Therefore P(A and B) = 25/50+15/50 - 5/50

Answer:The sample space that satisfies the definition of a continuous random variable is: ×=[0,500]
Step-by-step explanation:
The sample space that satisfies the definition of a continuous random variable is: ×=[0,500]
A continuous random variable is a variable that can take on any value within a certain range of values, typically a continuous interval. This means that there are an infinite number of possible values that the variable can take on, and the probability of any particular value is zero.
In contrast, the other sample spaces listed are all discrete random variables, meaning that they can only take on a finite or countable number of values. For example, the first sample space x={odd integers between 5 and 15} can only take on 6 possible values (5, 7, 9, 11, 13, or 15), and the third sample space x=[0,1,2,3] can only take on 4 possible values.
The fourth sample space x=[the number of days in the week that have the letter "r"] is also a discrete random variable, as it can only take on values of 0, 1, 2, or 3 (depending on how many days of the week have the letter "r").
Therefore, the only sample space that satisfies the definition of a continuous random variable is ×=[0,500].

The volume of the prism is B. 2.5 cubic inches.
How to calculate the volumeAccording to the question, the prism measures 1/4 of an inch on one side. Now we will assign values to the length, width, and height of this prism as follows:
Length = 2 × 1/4
Width = 5 × 1/4
Height = 3 × 1/4
= 2/4 + 5/4 + 3/4
= 2 2/4
= 2.5 cubic inches.
