A 4-yard dumpster cost $95.00 monthly how much would it cost for the year?
Answer options:
A) 190.00
B) 180.00
C) 170.00
D) 160.00
If a 4-yard dumpster cost $95.00 monthly, the total cost for the year is $1,140.
How is the total cost determined?The total cost for the year of the dumpster is the product of the multiplication of the monthly cost and 12.
Multiplication is one of the four basic mathematical operations, including addition, subtraction, and division.
In any multiplication, there must be the multiplicand (the number being multiplied), the multiplier (the number multiplying the multiplicand), and the product (or the result).
The monthly cost of the 4-yard dumpster = $95.00
1 year = 12 months
The total annual cost = $1,140 ($95 x 12)
Thus, using the multiplication operation, we can find that none of the options is correct as the total annual cost but $1,140.

Step-by-step explanation:
the see turtle population is modeled by equation p=400 x 5/4 power y
The value of p is 781.25.
What is a population growth?
Population Growth is defined as the increase in the number of individuals in a population is called population growth.
What is a common growth factor?
The growth factor is the ratio between the old price and the new price, once sales tax is included.
We want to know the population when y = 0, or when the number of years is zero.
Substitute the same in the equation
p = (400).\((\frac{5}{4} )^{y}\)
When y = 1 or at the 1st year, the population will be p = (400)(\(\frac{5}{4}\) ) = 500
This means that the population is increasing by a common growth factor of \((\frac{5}{4})\) .
When y = 3, or at year 3 we get the population as p = 400 \((\frac{5}{4} )^{3}\)

For the third week of April, Patricia Thomas worked 53 hours. Patricia earns $11.90 an hour. Her employer pays overtime for all hours worked in excess of 40
hours per week and pays 1.5 times the hourly rate for overtime hours.
Calculate the following for the third week of April (round your responses to the nearest cent if necessary):
1. Regular pay amount
2. Overtime pay
3. Gross pay
Given statement solution is :- For the third week of April, Patricia's:
Regular pay amount is $476.
Overtime pay is $231.45.
Gross pay is $707.45.
To calculate Patricia's pay for the third week of April, we'll need to determine her regular pay, overtime pay, and gross pay.
Regular Pay:
Patricia worked 53 hours, but only 40 hours are considered regular hours. Therefore, the regular pay is calculated as follows:
Regular Pay = Regular Hours x Hourly Rate
Regular Pay = 40 hours x $11.90/hour
Regular Pay = $476
Overtime Pay:
Since Patricia worked 53 hours in total and 40 of those are regular hours, the remaining 13 hours are considered overtime hours. Overtime pay is calculated by multiplying the overtime hours by 1.5 times the hourly rate.
Overtime Pay = Overtime Hours x (Hourly Rate x 1.5)
Overtime Pay = 13 hours x ($11.90/hour x 1.5)
Overtime Pay = 13 hours x $17.85/hour
Overtime Pay = $231.45
Gross Pay:
Gross Pay is the sum of Regular Pay and Overtime Pay.
Gross Pay = Regular Pay + Overtime Pay
Gross Pay = $476 + $231.45
Gross Pay = $707.45
Therefore, for the third week of April, Patricia's:
Regular pay amount is $476.
Overtime pay is $231.45.
Gross pay is $707.45.

How do I find the possible degree(s) of a function from the graph alone?
Answer:
To determine the possible degree(s) of a function from the graph alone, you need to examine the behavior of the graph at the extremes (far left and far right) and consider the number of turning points or changes in direction. Here's a step-by-step approach:
Look at the far left side of the graph: Determine the behavior of the graph as it approaches negative infinity. Does the graph approach a specific value, such as a horizontal line (asymptote) or the x-axis? If the graph approaches a horizontal line, it suggests a polynomial function of even degree. If the graph approaches the x-axis, it indicates a polynomial function of odd degree or possibly a function with a root of multiplicity greater than one.
Look at the far right side of the graph: Determine the behavior of the graph as it approaches positive infinity. Similar to step 1, observe if the graph approaches a specific value or a horizontal line. The behavior at the far right side should be consistent with the behavior at the far left side. This can help you identify if the function is even or odd degree.
Examine the number of turning points or changes in direction: Count the number of times the graph changes direction. These points are where the slope of the graph changes from positive to negative or vice versa. The number of turning points can provide an indication of the degree of the polynomial. For example, if there are two turning points, it suggests a polynomial function of degree 3.
Remember that this method provides potential degrees, but it may not definitively determine the exact degree of the function. Additional information or analysis might be required for a more accurate determination.

Small Sample:
During an economic downturn, 11 companies were sampled and asked whether they were planning to increase their workforce. Only 2 of the 11 companies were planning to increase their workforce. Use the small-sample method to construct an 80% confidence interval for the proportion of companies that are planning to increase their workforce. A pollster wants to construct a 95% confidence interval for the proportion of adults who believe that economic conditions are getting better. A poll taken in July 2010 estimates this proportion to be 0.36. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.01?
Answer:
The 80% confidence interval for the proportion of companies that are planning to increase their workforce is (0.033, 0.331).
A sample size of 8852 is needed.
Step-by-step explanation:
First question:
In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which
z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).
Only 2 of the 11 companies were planning to increase their workforce.
This means that \(n = 11, \pi = \frac{2}{11} = 0.1818\)
80% confidence level
So \(\alpha = 0.2\), z is the value of Z that has a pvalue of \(1 - \frac{0.2}{2} = 0.9\), so \(Z = 1.28\).
The lower limit of this interval is:
\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1818 - 1.28\sqrt{\frac{0.1818*0.8182}{11}} = 0.033\)
The upper limit of this interval is:
\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1818 + 1.28\sqrt{\frac{0.1818*0.8182}{11}} = 0.331\)
The 80% confidence interval for the proportion of companies that are planning to increase their workforce is (0.033, 0.331).
Second question:
The margin of error is:
\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)
A poll taken in July 2010 estimates this proportion to be 0.36.
This means that \(\pi = 0.36\)
95% confidence level
So \(\alpha = 0.05\), z is the value of Z that has a pvalue of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).
Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.01?
This is n for which M = 0.01. So
\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)
\(0.01 = 1.96\sqrt{\frac{0.36*0.64}{n}}\)
\(0.01\sqrt{n} = 1.96\sqrt{0.36*0.64}\)
\(\sqrt{n} = \frac{1.96\sqrt{0.36*0.64}}{0.01}\)
\((\sqrt{n})^2 = (\frac{1.96\sqrt{0.36*0.64}}{0.01})^2\)
\(n = 8851.04\)
Rounding up(as a sample of 8851 will have a margin of error slightly over 0.01):
A sample size of 8852 is needed.

What the meaning of "f is order-preserving if x < y implies f(x) < f(y)"?
An order-preserving function is a function that preserves the order of its inputs. In other words, if x is less than y, then f(x) will be less than f(y).
The statement "f is order-preserving if x < y implies f(x) < f(y)" means that if x is less than y, then f(x) must be less than f(y). This is a necessary condition for a function to be order-preserving. However, it is not a sufficient condition. For example, the function f(x) = x^2 is not order-preserving, because 2 < 3, but f(2) = 4 > f(3) = 9.
In summary, order-preserving functions are useful in situations where we need to preserve the order of a set of data.

Tan(x/2) = (1 + cosx)/sinx is equivalent to the trigonometric identity cscx
How to solve an equation?An equation is an expression that can be used to show the relationship between variables and numbers.
Trigonometric identities are based on the six trigonometric ratios. They are sine, cosine, tangent, cosecant, secant, and cotangent.
It is given as:
tanФ = sinФ/cosФ, cotФ = 1/tanФ = cosФ/sinФ, cosecФ = 1/sinФ and secФ = 1/cosФ
According to half angle formula:
tan(x/2) = (1 + cosx)/sinx
Hence:
tan(x/2) + cotx = [(1 - cosx)/sinx] + (cosx/sinx)
tan(x/2) + cotx = (1 - cosx + cosx)/sinx
= 1/sinx
= cscx
