The peaches required for every cup of water is 4/3
what is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
so;
A.T.Q:-
Is there two columns of data and two data points? Like this:
peaches Water
40 30
400 300
If so, then there are two ways to do it.
1) You can set up a ratio like this
40/30 = x
:-Where x is the number of peaches for every cups of water .
So;
x = 40/30 peaches
x = 4/3 peaches
2) Look at the increase from one to the other.
3 cups of water requires 4 peaches.
∵ Hence by unitary method
1 cup of water requires 4 /3 peaches.
:- so; 4/3 peaches are required for every cup of water.

A company XYZ issued 30 year bonds with 10% annual coupon rate at their par value of $1000 in 2010. The Bonds had a 7% call premium, with 5 years of call protection. Today XYZ called the bonds. Compute the realized rate of return for an investor who purchased the bonds when they were issued in 2010. Briefly explain why the investor should or should not be happy.
1. Tha rate of return is 11.12%
2. The investor will not be happy in case the market interest rates fall
How to illustrate the information?n is NPER 5 (called back in 5yrs)
Coupon payment / PMT = 1000 * 10% = 100,
Purchase price PV (PV is entered as a negative value) -1000
Called for value is FV Call premium is 7% hence FV = 107% * 1000 = 1070
You can use the RATE function in excel
Rate(nper, PMT, PV,FV, Type)
RATE(5,100,-1000,1070)
= 11.12%
The investor was promised a fixed return rate of 10%, but since the bond was called after 5 years, the actual return was 11.12%, so the investor had good reason to be pleased.
In the event that market interest rates decline, the investor will not be pleased because, had the bond not been called, he would have continued to receive his fixed 10% coupon payments of $100 per year.

Sales of SUVs (sport utility vehicles) in the United States (in millions) for the years 1990-1999 can be modeled by the quadratic equation shown below.y = 0.016x^2 +0.124x +0.787Here x = 0 represents 1990, x = 1 represents 1991, and so on. Use the model to approximate sales in 1995, Sales in 1995 were approximately ____ million SUVs.(Round to the nearest tenth as needed.)
The sales in 1995 were approximately 1.8 millions.
Explanation:
Since x = 0 is 1995, x = 1 is 1991 and so on, if we want to find the approximate amount of sales, we need to evaluate the expression for x = 5:

When the symbols ">," <","≤ ", or "≥" are used to connect two real numbers or algebraic expressions, the relationship is referred to as an inequality.Given:
Cost of each shirt = $12.99
Cost of each pant = $15.99
Let's assume the number of shirts is x and the number of pants is y.
Total cost of x shirts = $12.99x
Total cost of y pants = $15.99y
Total cost = $(12.99x+15.99y).

A coin is weighted so that there is a 58% chance that it will come up "heads" when flipped. The coin is flipped four times. Find the probability of getting two "heads" and two "tails". Round your answer to four decimal places.
P(A) =Probability of heads
P(B) = Probability of tails
P(B)= 1 - P(A) = 1 - 58 = 42%
The events are independent, so, let's assume that we flip the coin and the first two results are heads, so:
P(A) =0.58
Now, let's assume the last two results are tails so:
P(B) = 0.42
Therefore:
[tex]\begin{gathered} P(A\cap A\cup B\cap B)=P(A)\cdot P(A)\cdot P(A)+P(B)\cdot P(B) \\ P(A\cap A\cup B\cap B)=0.58\cdot0.58+0.42\cdot0.42=0.3364+0.1764=0.5128 \end{gathered}[/tex]The height of Debbie is 85 centimetres.

What is the revenue? (Round answer to the nearest cent.)
The revenue is at a maximum after x = 9
The maximum is $ 261
9 hearing aids are produced and sold.
The revenue, R(x), of producing and selling 'x' Awesome Hearing Aids is modeled by the function,
R(x) = -3x² + 56x
We need to find the number of hearing aids produced and sold in order to maximize the revenue.
We use the differentiation method to find the maximum of the function R(x).
Differentiate R(x) with respect to x and equate it with 0,
R'(x) = -6x + 56
Then, -6x + 56 = 0
⇒ 6x = 56
⇒ x = 56/6 = 9.33 ≈ 9 [since x is the number of hearing aids]
Now we find the second derivative of R(x) at x = 9.
R''(x) = -6
⇒ R''(9) = -6 < 0
Since R''(9) < 0, the revenue R(x) is maximum at x = 9.
So the maximum revenue is obtained after x = 9.
Therefore maximum revenue = R(9) = -3 x 9²+56 x 9 = $ 261
Hearing aids produced and sold in order to maximize the revenue = 9
