The graph shows the relationship between the United States dollar and the euro, the currency of the European Union, in December 2011. Part A: What is the constant of proportionality shown in the graph? *
Answers
The graph is missing, so i have attached it;
Answer:
Constant of proportionality = 0.75
Step-by-step explanation:
From the graph attached, we are given 3 coordinate points of (x, y) namely;
(120, 90), (250, 187.5), (400, 300)
Now, constant of proportionality for each coordinate point is simply;
k = y/x
Thus, for first coordinate point (120, 90),
k1 = 90/120
k1 = 0.75
For 2nd coordinate point (250, 187.5),
k2 = 187.5/250
k2 = 0.75
For third coordinate point (400, 300),
k3 = 300/400
k3 = 0.75
From each of the 3 points, we can see the constant of proportionality is the same and equal to 0.75.

An application of the Monte Carlo method to find the area Ac inside a circle uses a random sample of points Ns in a square area As surrounding the circle and counts the number of points that are found inside the circle Nc. Which expression describes the estimate for the area inside the circle
Answers
Answer:
As*Nc/Ns
Step-by-step explanation:
The square has Ns discrete points. The points are quite large and are close around each other
As = Area of square
Nc = number of points inside square
Ns = total number of points inside square
Ac = area of circle
Such that
Nc/Ns = Ac/As
We cross multiply
AcNs = NcAs
Dividing through by Ns will give:
Ac = NcAs/Na
Which Is also

Answers:
[tex]\displaystyle \lim_{n \to \infty} \frac{a_n}{b_n} = 6[/tex]
Based on the limit comparison test, the series is convergent
========================================================
Explanation:
As n gets really large, the terms [tex]3^n[/tex] and [tex]3^n-2[/tex] are effectively the same. Taking the limit to infinity of the ratio leads to 1.
In other words,
[tex]\displaystyle \lim_{n \to \infty} \frac{3^n}{3^n-2} = \lim_{n \to \infty} \frac{3^n}{3^n} = 1[/tex]
That -2 doesn't really play a role when n gets very large.
This result is then multiplied by the 6 in the [tex]a_n[/tex] sequence, getting 6 as the final limit we want.
So,
[tex]L = \displaystyle \lim_{n \to \infty} \left(a_n \div b_n\right)\\\\\\L = \displaystyle \lim_{n \to \infty} \left(\frac{6}{3^n-2} \div \frac{1}{3^n}\right)\\\\\\L = \displaystyle \lim_{n \to \infty} \left(\frac{6}{3^n-2} \times \frac{3^n}{1}\right)\\\\\\L = \displaystyle \lim_{n \to \infty} \left(\frac{6*3^n}{3^n-2}\right)\\\\\\[/tex]
[tex]L = \displaystyle 6*\lim_{n \to \infty} \left(\frac{3^n}{3^n-2}\right)\\\\\\L = \displaystyle 6*\lim_{n \to \infty} \left(\frac{3^n}{3^n}\right)\\\\\\L = \displaystyle 6*\lim_{n \to \infty} (1)\\\\\\L = \displaystyle 6*1\\\\\\L = \displaystyle 6\\\\\\[/tex]
Since the limiting value is positive and not infinity, this means that both series [tex]\sum a_n[/tex] and [tex]\sum b_n[/tex] converge or they both diverge.
----------------------------
If we plug n = 2 into the [tex]b_n[/tex] sequence, we get
[tex]b_n = \frac{1}{3^n}\\\\b_2 = \frac{1}{3^2}\\\\b_2 = \frac{1}{9}[/tex]
The first term is a = 1/9
If we plugged n = 3, we would get [tex]b_3 = \frac{1}{27}[/tex]
This shows that the common ratio is r = 1/3
Because -1 < r < 1 is true, we know that the infinite geometric series converges. Therefore, [tex]\sum b_n[/tex] converges. We don't need to find the converging value.
Going back to the limit comparison test, we stated that both [tex]\sum a_n[/tex] and [tex]\sum b_n[/tex] either diverge together or converge together.
We've shown that the b series converges, so the 'a' series must converge as well.

Your brother won 7 packages of colored candies with 24 pieces each. According to manufacture. For each 1 blue piece produced. The company makes 3 brown. 2 yellow. 2 red. 1 orange and 1 green. How many of each color do you expect to find in your brothers candy?
Answers
Answer:
16.8 or 17 blue
50.4 or 50 brown
33.6 or 34 yellow
33.6 or 34 red
16.8 or 17 orange
16.8 or 17 green
Step-by-step explanation:
7 x 24 = 168 candies
blue = b
brown = w
yellow = y
red = r
orange = o
green = g
1b = 3w + 2y + 2r + 1o + 1g
1 +3 + 2 + 2 + 1 + 1 = 10
168/10 = 16.8
1(16.8) +3(16.8) + 2(16.8) + 2(16.8) + 1(16.8) + 1(16.8) =
16.8 blue
50.4 brown

You can afford a $1350 per month mortgage payment. You’ve found a 30 year loan at 7% interest.
A) How big of a loan can you afford?
B) How much total money will you pay the loan company?
C) How much of that money is interest?
Answers
B) 1350 because 45 x 30 = 1350
C) 7% because it’s 7% to begin with
A) The loan amount you can afford is, $177,690.52
B) There will be paid a total of $486,000 to the loan company over the course of 30 years.
C) $308,309.48 of the total money you will pay the loan company is interest.
Given that,
You can afford a $1350 per month mortgage payment.
And, found a 30-year loan at 7% interest.
A) Using the formula for calculating the monthly mortgage payment, we can rearrange it to solve for the loan amount:
Loan Amount = [tex]\frac{Monthly Payment }{(Monthly Payment * (1 + (\frac{1}{1+Monthly Payment )^{Number of payments} } }[/tex]
Plugging in the given values:
Monthly Payment = $1350
Monthly Interest = 7% / 12
= 0.00583
Number of Payments = 30 years × 12 months
= 360
Hence,
Loan Amount = [tex]\frac{1350}{(0.00583 (1 + \frac{1}{1+ 0.00583)^{360} } )}[/tex]
By evaluating this expression,
the loan amount you can afford is,
$177,690.52
B) The total money you will pay the loan company,
Total Money Paid = Monthly Payment × Number of Payments
Total Money Paid = $1350 × 360
= $486,000
Therefore, you will pay a total of $486,000 to the loan company over the course of 30 years.
C) the amount of money which is interest,
Interest Paid = Total Money Paid - Loan Amount
Interest Paid = $486,000 - $177,690.52
= $308,309.48
Hence, $308,309.48 of the total money you will pay the loan company is interest.

linear equations to Standard Form y=10x-4
Answers
Answer:
The standard form of the linear equation is 10x - y = 4
Step-by-step explanation:
The standard form for linear equations in two variables is
Ax + By = C, where A, B, and C are integers
∵ The linear equation is y = 10x - 4
→ Let us move x from the right side to the left side by subtraction
10x from both sides
∴ y - 10x = 10x - 10x - 4
∴ y - 10x = -4
→ Multiply all terms in the two sides by -1
∴ -y + 10x = 4
→ Start the equation by x
∴ 10x - y = 4
∴ The standard form of the linear equation is 10x - y = 4

g Regression is a functional relationship between two or more correlated variables, where one or more variables are used to predict a single variable of interest. Group of answer choices True False
Answers
Answer:
True
Step-by-step explanation:
In regression analysis, it tries to infer that there is a supposed relationship between two or more variables.
Now it has a couple of functions such as;
It allows us to directly estimate the parameters in linear functions only, although there are some other ways in which it would allow many non - linear functional forms to get estimated indirectly.
Regression also allows us to test and find out if there is a functional relationship between two or more variables. This is done by testing the hypothesis whether each of the slopes have a value of zero.
Thus, from the definitions given, we can see that regression is a basically a functional relationship between two or more variables, where one or more variables are used to predict a single variable of interest.
Thus, the given statement is true.
