Answer:
To solve the system of equations using subtraction, you need to eliminate one of the variables by adding or subtracting the equations. In this case, we can eliminate x by multiplying the first equation by 2 and subtracting it from the second equation:
2x - 5y = 1
- (2(x - 6y) = 2x - 12y = 22)
------------------------
-17y = -21
Now we can solve for y:
-17y = -21
y = (-21) / (-17)
y = 1.2353
Substitute y into one of the original equations to solve for x:
x - 6y = 11
x - 6(1.2353) = 11
x - 7.4118 = 11
x = 18.4118
Therefore, x = 18.4118 and y = 1.2353.

The length of arc FED is approximately 51.1 yards, rounded to the nearest tenth.
What is an arc length?The length of a section of a circle's circumference is known as an arc length.
The radius of the circle and the angle the arc subtends at the centre of the circle are two variables that affect an arc's length.
To find the length of FED, we need to first find the measure of the arc EGD. Since a circle has 360 degrees, we can find the measure of arc EGD by subtracting the measures of arcs DGC, CGF, and FGE from 360:
m(EGD) = 360° - m(DGC) - m(CGF) - m(FGE)
m(EGD) = 360° - 80° - 47° - 90°
m(EGD) = 143°
The formula for arc length is:
Arc length = (central angle / 360) x (2πr)
We can use this information to find the radius of the circle:
FG = 2r
27 yd = 2r
r = 13.5 yd
Now we can use the formula for arc length to find the length of arc FED:
Arc length FED = ((∠FED) / 360) x (2πr)
We know that ∠(EGD) + ∠(FED) = 360, so we can solve for ∠(FED):
∠(FED) = 360° - ∠(EGD)
∠(FED) = 360° - 143°
∠(FED) = 217°
Plugging in the values, we get:
Arc length FED = (217° / 360) x (2π x 13.5 yd)
Arc length FED = (0.6028) x (84.78 yd)
Arc length FED = 51.11 yd

1. Suppose c = -11 + 3i. What two nonzero complex numbers could have been
added together to make c?
2. Find the value of iº.
Answer: To find two complex numbers that add up to c = -11 + 3i, we can set up the following system of equations:
a + b = -11
ai + bi = 3i
Solving for a and b, we can multiply the first equation by i and subtract it from the second equation multiplied by -1 to eliminate b:
ai + bi = 3i
-ai - bi = 11i
0 + 10bi = 14i
Simplifying, we get b = 1.4. Substituting this into the first equation gives:
a + 1.4 = -11
a = -12.4
So the two complex numbers that add up to c are -12.4 + 1.4i and 1.4i.
To find the value of iº, we need to evaluate i raised to the power of 90 degrees (or pi/2 radians) using Euler's formula:
e^(iθ) = cos(θ) + i sin(θ)
So we have:
iº = i^(90°) = e^(iπ/2) = cos(π/2) + i sin(π/2) = 0 + i(1) = i
Therefore, iº = i.

The ratio of the surface areas of two similar cylinders is 16/25
. The radius of the circular base of the larger cylinder is 0.5 centimeters.
What is the radius of the circular base of the smaller cylinder?
The radius of the circular base of the smaller cylinder is approximately 0.625 centimeters.
What is surface area?The surface area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.
The ratio of the surface areas of two similar cylinders is equal to the square of the ratio of their corresponding radii. Let r be the radius of the circular base of the smaller cylinder. Then we have:
(surface area of larger cylinder) / (surface area of smaller cylinder) = (r_l / r)² = 16/25
where r_l is the radius of the circular base of the larger cylinder.
We know that r_l = 0.5 cm, so we can solve for r:
(r_l / r)² = 16/25
(0.5 / r)² = 16/25
0.25 / r² = 16/25
r² = 0.25 * 25 / 16
r² = 0.390625
r = √(0.390625) ≈ 0.625

For each of the following three scenarios, state which hypothesis test you would use from among the four introduced so far: the z test, the single-sample t test, the paired-samples t test, and the independent-samples t test. (Note: In the actual studies described, the researchers did not always use one of these tests, often because the actual experiment had additional variables.) Explain your answer. (20pts) a. A study of 40 children who had survived a brain tumor revealed that the children were more likely to have behavioral and emotional difficulties than were children who had not experienced such a trauma (Upton & Eiser, 2006). Parents rated children’s difficulties, and the ratings data were compared with known means from published population norms. b. Talarico and Rubin (2003) recorded the memories of 54 students just after the terrorist attacks in the United States on September 11, 2001—some memories related to the terrorist attacks on that day (called flashbulb memoriesfor their vividness and emotional content) and some everyday memories. They found that flashbulb memories were no more consistent over time than everyday memories, even though they were perceived to be more accurate. c. The HOPE VI Panel Study (Popkin & Woodley, 2002) was initiated to test a U.S. program aimed at improving troubled public housing developments. Residents of five HOPE VI developments were examined at the beginning of the study so researchers could later ascertain whether their quality of life had improved. Means at the beginning of the study were compared to known national data sources (e.g., the U.S. Census, the American Housing Survey) that had summary statistics, including means and standard deviations.
Answer:
a. For the study of 40 children who had survived a brain tumor, the appropriate hypothesis test would be a single-sample t test. This is because the study involves comparing the ratings data from the parents with known means from published population norms. A single-sample t test is used to determine whether a sample mean is statistically different from a known population mean. In this case, the sample mean is the ratings data from the parents, and the population mean is the known means from published population norms.
b. For Talarico and Rubin's study of memories, the appropriate hypothesis test would be a paired-samples t test. This is because the study involves comparing the consistency of flashbulb memories and everyday memories over time, for the same group of individuals. A paired-samples t test is used to determine whether there is a statistically significant difference between two related samples, such as before and after measurements for the same group of individuals.
c. For the HOPE VI Panel Study, the appropriate hypothesis test would be an independent-samples t test. This is because the study involves comparing the means of residents in the five HOPE VI developments at the beginning of the study with known national data sources that had summary statistics, including means and standard deviations. An independent-samples t test is used to determine whether there is a statistically significant difference between the means of two independent groups. In this case, the two independent groups are the residents in the HOPE VI developments and the known national data sources.

Find the final amount of a $750 investment after 15 years at 8% interest compounded semiannually, quarterly and daily.
With given compound interest, the final amount of the investment after 15 years at 8% interest compounded semiannually, quarterly and daily are $2,067.87, $2,094.28, and $2,101.62, respectively.
What is Compound interest?
Compound interest is the addition of interest to the principal sum of a loan or deposit, or the interest earned on both the principal and any previously accrued interest. In other words, interest is computed not only on the original amount of money but also on any past interest gained. The interest generated on the cumulative interest can compound exponentially, resulting in enormous growth of an investment or loan sum over time. Compound interest is computed using a formula that takes the principle amount, interest rate, and compounding frequency into consideration.
Now,
To find the final amount of the investment, we can use the formula for compound interest:
A = P(1 + r/n)ⁿˣ
where:
A = final amount
P = principal (initial investment)
r = annual interest rate
n = times the interest is compounded per year
x = time in years
For semiannual compounding, n = 2 and x = 15:
A = 750(1 + 0.08/2)²*¹⁵= $2,067.87
For quarterly compounding, n = 4 and x = 15:
A = 750(1 + 0.08/4)⁴*¹⁵ = $2,094.28
For daily compounding, n = 365 (assuming no leap years) and x = 15:
A = 750(1 + 0.08/365)³⁶⁵*¹⁵ = $2,101.62
Therefore, the final amount of the investment after 15 years at 8% interest compounded semiannually, quarterly and daily are $2,067.87, $2,094.28, and $2,101.62, respectively.

What is a fraction?
A fraction is written as a ratio of two integers, where the number on top is called the numerator and the number on the bottom is called the denominator. The denominator represents the total number of equal parts that make up a whole, while the numerator represents the number of parts that are being considered. For example, the fraction 2/5 represents 2 parts out of 5 equal parts that make up the whole. Fractions can be used to represent numbers between whole numbers, such as 1/2, 3/4, and 7/8.
Now,
The coupon rate of the bond is 6 5/8 or 6.625%.
The maturity date is not explicitly given in the bond listing. However, based on the convention used in bond listings, the year of maturity can be inferred from the number in the bond name. In this case, the bond name is "PacBell 6 5/8 34", which suggests that the bond matures in 2034.

How to calculate volume of cylinder?We can use the formula for the volume of a cylinder to solve this problem:
[tex]V = \pi r^2h[/tex]
We know that the volume V is 2,035.75 [tex]in^3[/tex], and the height h is 3 times the radius r. So we can write:
[tex]V = \pi r^2(3r)[/tex]
Simplifying this expression, we get:
V = 3π[tex]r^3[/tex]
To solve for r, we can divide both sides of the equation by 3π[tex]r^2[/tex]:
V/(3π[tex]r^2[/tex]) = r
Substituting the given value for V, we have:
2,035.75/(3π[tex]r^2[/tex]) = r
Multiplying both sides by 3πr^2, we get:
2,035.75 = 3π[tex]r^3[/tex]
Dividing both sides by 3π, we have:
[tex]r^3[/tex] = 2,035.75 / (3π)
Taking the cube root of both sides, we get:
r = [tex](2,035.75 / (3\pi ))^{1/3[/tex]
Using a calculator, we find that:
r ≈ 6.75 inches
Therefore, The cylinder has a radius of about 6.75 inches.

Describe the transformations (vertical translation, horizontal translation, and dilation/reflection) from the parent function that happened to these formulas
The formula g(x) = 2 * 0{-10≤x+3≤10} represents a function that has been horizontally shifted left by 3 units, reflected about the y-axis, and vertically scaled by a factor of 2.
What is Function?A function is a mathematical rule that assigns each input from a set (domain) a unique output from another set (range), typically written as y = f(x).
The notation "0{-10≤x≤10}" typically represents the domain of a function or an inequality. It means that the function is defined only for the values of x that are between -10 and 10 (including -10 and 10).
Assuming that the function in question is a constant function equal to zero, the parent function is f(x) = 0.
To describe the transformations that happened to this function, we need more information about the specific formula. For example, if the formula is:
g(x) = 0{-10≤x≤10}
Then there are no transformations from the parent function. The function is simply a constant function that is equal to zero over the interval [-10, 10].
However, if the formula is something like:
g(x) = 2 * 0{-10≤x+3≤10}
Then we can describe the transformations as follows:
Horizontal translation: The function has been shifted horizontally to the left by 3 units. This means that the point (3, 0) on the parent function is now located at the origin (0, 0) on the transformed function.
Dilation/reflection: The function has been reflected about the y-axis and vertically scaled by a factor of 2. This means that the point (-1, 0) on the parent function is now located at (-4, 0) on the transformed function, and the point (1, 0) on the parent function is now located at (2, 0) on the transformed function.
Vertical translation: There is no vertical translation in this case, since the constant function is already centered at y = 0.
To summarize, the formula g(x) = 2 * 0{-10≤x+3≤10} represents a function that has been horizontally shifted left by 3 units, reflected about the y-axis, and vertically scaled by a factor of 2.

La Suma delos cuadrados de dos números naturales consecutivos es 181 halla dichos numeros
The two consecutive natural numbers whose sum of squares is 181 are 9 and 10
Let's assume that the two consecutive natural numbers are x and x+1. Then, we can write an equation based on the given information:
x² + (x+1)² = 181
Expanding the equation:
x² + x² + 2x + 1 = 181
Combining like terms:
2x² + 2x - 180 = 0
Dividing both sides by 2:
x² + x - 90 = 0
Now, we can use the quadratic formula to solve for x:
x = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 1, and c = -90
x = (-1 ± √(1 + 360)) / 2
x = (-1 ± √(361)) / 2
x = (-1 ± 19) / 2
We discard the negative value, as it does not correspond to a natural number:
x = 9
Therefore, the two consecutive natural numbers are 9 and 10, and their sum of squares is 81 + 100 = 181.

What are similar triangles?Similar triangles are triangles that share these two features listed as follows:
Congruent angle measures, as both triangles have the same angle measures.Proportional side lengths, which helps us find the missing side lengths.First we must obtain the bases, splitting the figure into two separate similar triangles, with equivalent dimensions given as follows:
16 and y.30 and 34 - y.Hence the proportional relationship used to obtain the value of y is given as follows:
16/y = 30/(34 - y)
Hence:
30y = 16(34 - y)
46y = 544
y = 544/46
y = 11.83.
Hence the bases are:
11.83 and 34 - 11.83 = 22.17.
Applying the geometric mean theorem, the value of x is given as follows:
x = sqrt(11.83 x 22.17)
x = 16.2.

. Bert has a well-shuffled standard deck of 52 cards, from which he draws one card; Ernie has a 12-sided die, which he rolls at the same time Bert draws a card. Compute the probability that:
a. Bert gets a Jack and Ernie rolls a five.
b. Bert gets a heart and Ernie rolls a number less than six.
c. Bert gets a face card (Jack, Queen or King) and Ernie rolls an even number.
d. Bert gets a red card and Ernie rolls a fifteen.
e. Bert gets a card that is not a Jack and Ernie rolls a number that is not twelve.
Therefore , the solution of the given problem of probability comes out to be a)1/78 ,b)65/624 ,c)1/4 ,d)0 and e)12/13.
What is probability, exactly?The basic goal of any considerations technique is to assess the probability that a statement is accurate or that a specific incident will occur. Chance can be represented by any number range between 0 and 1, where 0 normally indicates a percentage but 1 typically indicates the level of certainty. An illustration of probability displays how probable it is that a specific event will take place.
Here,
a.
P(Bert gets a Jack and Ernie rolls a five) = P(Bert gets a Jack) * P(Ernie rolls a five)
= (4/52) * (1/12)
= 1/78
b.
P(Bert gets a heart and Ernie rolls a number less than six) = P(Bert gets a heart) * P(Ernie rolls a number less than six)
= (13/52) * (5/12)
= 65/624
c.
P(Bert gets a face card and Ernie rolls an even number) = P(Bert gets a face card) * P(Ernie rolls an even number)
= (12/52) * (6/12)
= 1/4
d.
P(Bert gets a red card and Ernie rolls a fifteen) = 0
e.
Ernie rolls a number that is not twelve, and Bert draws a card that is not a Jack:
A regular 52-card deck contains 48 cards that are not Jacks,
so the likelihood that Bert will draw one of those cards is 48/52, or 12/13.
On a 12-sided dice with 11 possible outcomes,
Ernie rolls a non-12th-number (1, 2, 3, etc.).
