We are given the percentages for males on the left side and the percentages for females on the right side.
We are trying to find four groups that make up nearly 1/2 of the male population, so we want the percentages for these groups to add up to nearly 50%.
Let's take a look at the lowest age groups of the male population, which in turn make up the highest proportion of the male population.
We have the age group 0-4, which makes up roughly 12%.
We have the age group 5-9, which makes up roughly 11%.
We have the age group 10-14, which makes up roughly 11%.
We have the age group 15-19, which makes up roughly 12.5%.
If we add all of these percentages together, we get:
12% + 11% + 11% + 12.5% = 46.5%
Since we cannot go any smaller than 46.5% because this is the closest percentage to 50%, the four groups that make up nearly one half of the male population must be:
Ages 0-4, 5-9, 10-14, and 15-19

Find slope and y-intercept12x = 2y+1
Answers
12x = 2y+1
First, express in slope-intercept form
y= mx +b
Where:
m = slope
b= y -intercept
So, we have to solve for y:
12x=2y+1
-2y= -12x+1
y= (-12x+1)/-2
y = 6x-1/2
So:
Slope = 6
Y-intercept = -1/2 or -0.5 (decimal form)

-5x + 3 > (-7x) - 12
Answers
Solve the inequality
-5x + 3 > (-7x) - 12
We want to move the variables to the left side and the numbers to the right side. The (-7x) can be eliminated from the right side by adding 7x on both sides.
Add 7x to both sides:
-5x + 3 + 7x > -12
We need to move the 3 from the left to the right side. So we subtract 3
Subtract 3 to both sides:
-5x + 7x > -12 - 3
Joining like terms:
2x > -15
Solving:
x > -15/2
The solution is every real number greater than -15/2

Joan invests $200. She earns interest at 3% per annum, compounded monthly.What is the future value of Joan’s investment after 1.5 years?
Answers
For this exercise you need to use the following formula:
[tex]FV=PV\mleft(1+r\mright)^n[/tex]Where "FV" is the future value, "PV" is the present value, "r" is the interest rate (in decimal form), and "n" number of periods.
In this case, analyzing the information given in the exercise, you can identify that:
[tex]PV=200[/tex]Remember that a percent can be written in Decimal form by dividing it by 100. Then:
[tex]\frac{3}{100}=0.03[/tex]Since she earns interest at 3% per annum and it is compounded monthly, you can determine that the interest rate per month is:
[tex]r=\frac{0.03}{12}=0.0025[/tex]Knowing that 1 year has 12 months, you know that:
[tex](12)(1.5\text{ }years)=18\text{ }months[/tex]Then:
[tex]n=18[/tex]Therefore, you can substitute all those values into the formula and then evaluate, in order to find the future value of Joan’s investment after 1.5 years:
[tex]\begin{gathered} FV=PV(1+r)^n \\ FV=(200)(1+0.0025)^{18} \\ FV=(200)(1.0025)^{18} \end{gathered}[/tex][tex]FV\approx209.19[/tex]Hence, the answer is: $209.19 (approximately).

Differentiation from First Principles is a formal method for determining a tangent's gradient.
What is meant by differentiation?Finding a function's derivative is the process of differentiation. It is also the process of determining how quickly a function changes in relation to its variables.
According to the Sum rule, a sum of functions' derivatives equals the sum of those functions' derivatives. The derivative of two different functions is the difference of their derivatives, according to the Difference rule.
Differentiation from First Principles is a formal method for determining a tangent's gradient. The straight line connecting any two locations on the curve that are fairly near to one another will have a gradient that is similar to that of the tangent at those places.
s(t) = ∫vdt = ∫sin(πt)dt = (-cos(πt))/π + c
substituting the values t = 3, we get
s(-3) = (-cos(-3π))/π + c = 0
simplifying the above equation, we get
(-cos(3π))/π + c = 0
1/π + c = c
c = -1/π
Therefore, the correct answer is s(t) = (-cos(πt))/π - 1/π = (-cos(πt) - 1)/π.

At the ice cream factory you manage you have a rush order for 1200 gallons of wainut fudge ice cream. One machine can produce 100 gallons of ice cream every 80 minutes. If you start production on that machine at 6:00 am, about what time will be production run end end?
Answers
Given that the machine takes 80 minutes to produce 100 gallons of ice cream, so the rate of production (r) is given by,
[tex]\begin{gathered} r=\frac{100}{80} \\ r=1.25\text{ gallons/min} \end{gathered}[/tex]So the time required to produce 1200 gallons of the ice cream is calculated as,
[tex]\begin{gathered} t=\frac{1200}{r} \\ t=\frac{1200}{1.25} \\ t=960\text{ min} \end{gathered}[/tex]Thus, 960 minutes are required for producing 1200 gallons of ice cream.
Converting into hours,
[tex]\begin{gathered} 960\text{ minutes=}\frac{960}{60}\text{ hours} \\ 960\text{ minutes=}16\text{ hours} \end{gathered}[/tex]The time 16 hours after 6:00 am will be 22:00 which corresponds to 10:00 pm.
Therefore, the product run will end at 10:00 pm.
Suppose Rachel and Nadia buy a house and have to take out a loan for $183500. If they qualify for an APR of 3.75% and choose a 30 year mortgage, we can find their monthly payment by using the PMT formula. If Rachel and Nadia decide to pay $1500 per month, we can use goal seek to see how many years it will take to pay off the loan. Use the PMT function and goal seek (as needed) to answer the following questions about Rachel and Nadia's mortgage. a. What is their monthly payment on the 30 year loan? $ 15 year loan, what will the new monthly payment be?
Answers
We have that the PMT formula is given by:
[tex]\text{PMT}=p(\frac{\frac{r}{n}}{1-(1+\frac{r}{n})^{-ny}})[/tex]Where p is the initial principal (Loan ammount), r is the interest rate period, n is the total number of payments or periods, y is the number of years, PMT is the monthly payment.
Now, replacing the data in the formula, we will get:
*The payment will be due for 30 years, that is 12 months each year [That is our n] and y will be 30, r is 0.0375.
p will be $183500, that is:
[tex]\text{PMT}=(183500)(\frac{\frac{0.0375}{12}}{1-(1\pm\frac{0.0375}{12})^{-(12)(30)}})[/tex]Then, we will have that the monthly payment for the 30 years, should be:
[tex]\text{PMT}=849.8171105[/tex]If she wishes to pay $1500 each mothn, we then replace in the formula:
[tex]1500=(183500)(\frac{(\frac{0.0375}{12})}{1-(1+\frac{0.0375}{12})^{-12y}}[/tex]Now, solving for Y, we will have:
[tex]-12y=\frac{\ln(\frac{593}{960})}{\ln(\frac{321}{320})}\Rightarrow y\approx12.86643229[/tex]From this, we have that if they pay a monthly morgage of 1500, they would take 13 years to pay the total cost.
If they wanted to pay the morgage in 15 years, then we replace in the formula as follows:
[tex]\text{PMT}=(183500)(\frac{(\frac{0.0375}{12})}{1-(1\pm\frac{0.03755}{12})^{-12(15)}})[/tex]That is:
[tex]\text{PMT=1334.453182}\Rightarrow PMT\approx1334.45[/tex]They would have to pay $1334.45 each month in order to pay the morgage in 15 years.
Tamarisk Corporation is considering purchasing a new delivery truck. The truck has many advantages over the company's current truck (not the least of which is that it runs). The new truck would cost $56,619. Because of the increased capacity, reduced maintenance costs, and increased fuel economy, the new truck is expected to generate cost savings of $8,100. At the end of eight years, the company will sell the truck for an estimated $28,500. Traditionally, the company has used a general rule that it should not accept a proposal unless it has a payback period that is less than 50% of the asset's estimated useful life. Thomas Anderson, a new manager, has suggested that the company should not rely only on the payback approach but should also use the net present value method when evaluating new projects. The company's cost of capital is 8%.
Answers
The cash Payback period is 6.66 years and the Net present value of the proposed investment is $5,329 (to see the calculation please refer the attached image.)
Computation of Payback Period
Cash Payback Period = Cost of truck/Annual cost savings.
Given that-
Cost of truck = $56,619
Annual cost savings = $8,100
Putting values, we get-
Cash payback period = ($56,619/$8,100) cash payback period
cash payback period = 6.66 years.
To calculate the PVF at 8% below is the formula
P = (1/[tex](1+r)^{n}[/tex])
Where,
P = the Present Value Factor.
r = the interest rate
n = the number of periods over which payments are made.

What is a polygon?
A polygon (/pln/) in geometry is a planar figure characterized by a limited number of straight line segments joined to create a closed polygonal chain (or polygonal circuit). A polygon is defined as a bounded planar region, a bounding circuit, or both. A polygonal circuit's segments are known as its edges or sides. The vertices (plural: vertex) or corners of a polygon are the spots where two edges meet. A solid polygon's interior is sometimes referred to as its body. A polygon having n sides is known as an n-gon. A simple polygon is one that does not cross itself. Mathematicians are frequently interested simply in the bounding polygonal chains of simple polygons, and they frequently define a polygon in this manner.
The sides ratio is same in both polygons i.e. 1:2
and all the angles of the two polygons are congruent
