(D). 8 Wine, 16 Cloth
Step-by-step explanation:Cloth production by Argentina = 20 units
Wine production by Argentina = 2 units
Cloth production by Chile = 24 units
Wine production by Chile = 12 units
Now,
2 units of labor was transferred by Argentina from Wine to Cloth and 1 unit of labor was transferred by Chile from Cloth to Wine.
Therefore,
Increase in Cloth production = Argentina's total cloth produced - Cloth produced by Chile (before transfer)
Now,
We can say that total cloth produced by Argentina is = 2 x 20 = 40 units
So,
Increase in Cloth production = 40 - 24 = 16 units
Therefore, the increase in Cloth Production is 16 units.
Similarly,
Increase in Wine production = Chile's total Wine produced - Wine produced by Argentina (before transfer)
Now,
We can say that total Wine produced by Chile is = 1 x 12 = 12 units
Wine produced by Argentina before transfer = 2 x 2 = 4 units
So,
Increase in Wine production = 12 - 4 = 8 units
Therefore, the increase in Wine Production is 8 units.
Hence, the correct option is (D).
Express the confidence interval 0.333 < p < 0.777 in the form p +/- E.
Answer:
p= 0.555 ; E= 0.222; then we have 0.555 +/- 0.222
Step-by-step explanation:
The confidence interval goes from 0.333 to 0.777.
To find the p, we need to locate the median of that series of numbers.
The median is 0.555 as is the middle value of that interval.
Now the E corresponds to the deviation or the Error that we can measure.
And since we know that our variance ranges between 0.333 and 0.777, we can sustract 0.333 to p and we can get 0.222. We can also check if we add 0.222 to p, and we can get 0.777.

Laney walks one and two thirds of a mile to school from her house and rides the buss home. If she walked five days last week, how many miles did Laney walk in total?
Answer:
8 1/3
Step-by-step explanation:
The question is asking how many TOTAL (meaning it is increased so it could either be multiplication or addition) miles Loney walked in FIVE days. She walk 1 2/3 A DAY. This can be solved in two ways: multiplication AND addition. Addition: you just have tot turn the mixed fraction into improper fraction and then add the answer five times. But...wouldn’t multiplication be faster and easier..? Sure.
Step 1: Turn mixed fraction into improper.
1 2/3 as an improper fraction is 5/3. How? well multiply and denominator and the whole number and then add the numerator!
Step 2. Make an equation.
The equation should look like 5/3 x 5/1 (1 under 5 because remember there is ALWAYS an imaginary 1 under whole number while multiplying with fractions!)
Step 3. Multiply across
5x5=25
3x1=3 so it’s 25/3. There isn’t any LCM between 25 and 3 so we can only turn it into mixed number (you DEFINITELY can’t leave it like that! You MUST reduce to lowest terms for the correct answer!)
Step 4. Turn back into a mixed number.
there are several ways to do this.
1. Divided 25 by 3 and put the quotient as a whole number, remainder as a numerator and keep the same denominator.
OR
2. More faster way (if you know multiplication tables!)
How many times does 3 (denominato) goes into 25(numerator)? Well, read out the multiplication tables of 3!
3 times 8 equals 24! 3x9 will make it 27 so it doesn’t match with our numerator. So the answer is times 8! It becomes our whole number and it’s still 24 and our numerator is 25 so we have 1. Therefore, 1 is our numerator and we keep the same denominator :)
Hence, the answer is 8 1/3! Hope it helped! :D
The number of miles that Laney walked in total will be 25/3 miles.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
Laney walks one and two-thirds of a mile to school from her house and rides the bus home. If she walked five days last week.
Then the number of miles that Laney walked in total will be given by the product of the 1 2/3 and 5.
Number of miles = (1 2/3) x 5
Number of miles = (5/3) x 5
Number of miles = 25 / 3 miles
The number of miles that Laney walked in total will be 25/3 miles.

In an orienteering class, you have the goal of moving as far (straight-line distance) from base camp as possible by making three straight-line moves. You may use the following displacements in any order: (a) →a, 2.0 km due east (directly toward the east); (b) →b, 2.0 km 30° north of east (at an angle of 30° toward the north from due east); (c) →c, 1.0 km due west. Alternatively, you may substitute either −→b for →b or −→c for →c. What is the greatest distance you can be from base camp at the end of the third displacement? (We are not concerned about the direction.)
Answer:
The greatest distance we can be from the base camp at the end of the third displacement is 6.69 km
Step-by-step explanation:
We can think of each displacement as a vector, with a given magnitude and direction.
A vector can be written using its x and y coordinates like this
[tex]\vec{t}=(x, y)[/tex]
So, for the displacements a and c their vector coordinates would be:
[tex]\vec{a}=(2, 0)[/tex]
[tex]\vec{c}=(-1, 0)[/tex]
As the b displacement has an angle of 30° toward the north from due east, we can find its x and y coordinates using the following formulas:
[tex]x=(magnitude)*cos(angle)[/tex]
[tex]y=(magnitude)*sin(angle)[/tex]
Note: the angle in the formula is the one formed with the east measured counterclockwise.
So, the x and y coordinates for the b displacement will be:
[tex]\vec{b}=(2*cos(30), 2*sin(30))[/tex]
As the vector additon is commutative, the order won't affect the final position. Nevertheless, any change in the direction of any displacement will change the final position. So, in order to find the combination greatest distance we should calculate the following additions and find the one with the greatest magnitude:
[tex]\vec{R_{1}} =\vec{a}+\vec{b}+\vec{c}[/tex]
[tex]\vec{R_{2}} =\vec{a}-\vec{b}+\vec{c}[/tex]
[tex]\vec{R_{3}} =\vec{a}+\vec{b}-\vec{c}[/tex]
[tex]\vec{R_{4}} =\vec{a}-\vec{b}-\vec{c}[/tex]
Each resultant vector can be found adding each component. Afterwards, the magnitude can be found using the following formula:
[tex]|\vec{R}|=\sqrt[ ]{(R_{x})^2 +{(R_{y})^2}}[/tex]
Now, let's calculate!
[tex]\vec{R_{1}} =\vec{a}+\vec{b}+\vec{c}[/tex]
[tex]R_{1_x}} =2+2*cos(30)-1=2.73[/tex]
[tex]R_{1_y}} =0+2*sin(30)+0=1[/tex]
[tex]\vec{R_{1}}=(2.73,1)[/tex]
[tex]|\vec{R_{1}}|=\sqrt[ ]{(2.73)^2 +{(1)^2}}=3.86[/tex]
[tex]\vec{R_{2}} =\vec{a}-\vec{b}+\vec{c}[/tex]
[tex]R_{2_x}} =2-2*cos(30)-1=0.73[/tex]
[tex]R_{2_y}} =0-2*sin(30)+0=-1[/tex]
[tex]\vec{R_{2}}=(-0.73,-1)[/tex]}
[tex]|\vec{R_{2}}|=\sqrt[ ]{(-0.73)^2 +{(-1)^2}}=1.03[/tex]
[tex]\vec{R_{3}} =\vec{a}+\vec{b}-\vec{c}[/tex]
[tex]R_{3_x}} =2+2*cos(30)+1=4.73[/tex]
[tex]R_{3_y}} =0+2*sin(30)-0=1[/tex]
[tex]\vec{R_{3}}=(4.73,1)[/tex]
[tex]|\vec{R_{3}}|=\sqrt[ ]{(4.73)^2 +{(1)^2}}=6.69[/tex]
[tex]\vec{R_{4}} =\vec{a}-\vec{b}-\vec{c}[/tex]
[tex]R_{4_x}} =2-2*cos(30)+1=1.26[/tex]
[tex]R_{4_y}} =0-2*sin(30)-0=1[/tex]
[tex]\vec{R_{4}}=(1.26,-1)[/tex]
[tex]|\vec{R_{4}}|=\sqrt[ ]{(1.26)^2 +{(-1)^2}}=1.79[/tex]
So, after all the calculation, we can know for sure that the vector [tex]\vec{R_{3}}[/tex] has the biggest magnitude. Then, the greatest distance we can be from the base camp at the end of the third displacement is 6.69 km
Final answer:
To maximize your distance from base camp, move 2.0 km east, then 2.0 km 30° north of east, and finally 1.0 km west. The total distance achievable is around 3.732 km. The order of displacements does not affect the maximum distance reached.
Explanation:
The greatest distance you can be from base camp at the end of the third displacement is achieved when you move 2.0 km due east, then 2.0 km 30° north of east, and finally 1.0 km due west in any order.
This results in a total distance of approximately 3.732 km from base camp.
Regardless of the order in which you take the displacements, the resultant greatest distance achieved remains the same.

The standard quantity of metal per ring is 0.57 kilograms.
Step-by-step explanation:
Each ring requires 0.52 kilograms of a special metal.
The allowance for waste is 0.03 kilograms per ring, while the allowance for rejects is 0.02 kilograms per ring.
So, the standard quantity of metal per ring = 0.52 kg of metal required + 0.03 kg of allowance for waste + 0.02 kg of allowance for rejects)
= [tex]0.52+0.03+0.02=0.57[/tex] kilograms.
Hence, the standard quantity of metal per ring is 0.57 kilograms.

For some constants a and b let \[f(x) = \left\{ \begin{array}{cl} 9 - 2x & \text{if } x \le 3, \\ ax + b & \text{if } x > 3. \end{array} \right.\]The function f has the property that f(f(x)) = x for all x. What is a + b?
Answer:
The value of a+b is 4.
Step-by-step explanation:
The given function is
[tex]\[f(x) = \left\{ \begin{array}{cl} 9 - 2x & \text{if } x \le 3, \\ ax + b & \text{if } x > 3. \end{array} \right.\][/tex]
It is given that for some constants a and b the function f has the property that f(f(x))=x for all x.
For x≤3,
[tex]f(x)=9-2x[/tex]
For x>3,
[tex]f(x)=ax+b[/tex]
At x=0,
[tex]f(0)=9-2(0)=9[/tex]
[tex]f(f(0))=f(9)\Rightarrow a(9)+b=9a+b[/tex]
Using property f(f(x))=x,
[tex]f(f(0))=0[/tex]
[tex]9a+b=0[/tex] .... (1)
At x=1,
[tex]f(1)=9-2(1)=7[/tex]
[tex]f(f(1))=f(7)\Rightarrow a(7)+b=7a+b[/tex]
Using property f(f(x))=x,
[tex]f(f(1))=1[/tex]
[tex]7a+b=1[/tex] .... (2)
Subtract equation (2) from equation (1).
[tex]9a+b-(7a+b)=0-1[/tex]
[tex]2a=-1[/tex]
Divide both sides by 2.
[tex]a=-\frac{1}{2}[/tex]
Substitute this value in equation (1).
[tex]9(-\frac{1}{2})+b=0[/tex]
[tex]b=\frac{9}{2}[/tex]
The value of a is [tex]-\frac{1}{2}[/tex] and value of b is [tex]\frac{9}{2}[/tex]. The value of a+b is
[tex]a+b=-\frac{1}{2}+\frac{9}{2}[/tex]
[tex]a+b=4[/tex]
Therefore the value of a+b is 4.
A gardener is going to plant 2 red rosebushes and 2 white rosebushes. If the gardener is to select each of the bushes at random, one at a time, and plant them in a row, what is the probability that the 2 rosebushes in the middle of the row will be the red rosebushes?
a) 1/12
b) 1/6
c) 1/5
d) 1/3
e) ½
Answer: b) [tex]\dfrac{1}{6}[/tex]
Step-by-step explanation:
Sample space for the arrangement of red bushes :
[rrww , rwwr , wwrr , wrwr, rwrw , wrrw]
i.e. Total possible outcomes = 6
If the two rosebushes middle of the row are red , then the first and the last rosebushes must be white (wrrw).
i.e. the number of favorable outcomes for middle of the row are red =1
Now, the probability that the 2 rosebushes in the middle of the row will be the red rosebushes :
[tex]\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}\\\\=\dfrac{1}{6}[/tex]
Hence, the correct answer is option (b).
A space plane skims the edge of space at 4000 miles per hour. Neglecting altitude, if the circumference of the planet is approximately 25000 miles, how long will it take for the plane to travel around the planet?
A plane traveling at a speed of 4000 miles per hour would take approximately 6.25 hours to travel around a planet with a circumference of 25,000 miles.
Explanation:To solve this question, we will use the concept of time, speed, and distance. We know that the plane travels at a speed of 4000 miles per hour and the Earth's circumference is 25000 miles. Thus to compute the time it would take for the plane to travel around the planet, we can use the relation 'Time = Distance / Speed'.
The distance in this case is the circumference of the Earth, which is 25000 miles and the speed is the plane's speed, which is 4000 miles/hour. So, we simply divide 25000 miles by 4000 miles/hour:
Time = 25000 / 4000 = 6.25 hours

(1 pt) A data set consists of the 11 data points shown below, plus one additional data point. When the additional point is included in the data set, the sample standard deviation of the 12 points is computed to be 12.091. If it is known that the additional data point is 25 or less, find the value of the twelfth data point. 25, 41, 49, 25, 30, 13, 31, 34, 27, 54, 38 Value of the additional data point
Answer:
12.83
Step-by-step explanation:
S = 12.091
N = 12
We must find the 12th point, X
The formula of S² (variance) as a function of µ (media) is as follows:
S² = (1/N Ʃ Xi²) - µ²
S² = 146.2
Multiplying both members by N,
N S² = Ʃ Xi² – N µ²
On the other hand,
µ = (25 + 41 + 49 + 25 + 30 + 13 + 31 + 34 + 27 + 54 + 38 + X) / 12
µ = (367 + X) / 12
Replacing,
12 x 146.2 = 13607 + X² – 12 (367 + X)² / 144
1754.4 = 13607 + X² – 0.0833 (134689 + 734 X + X²)
1754.4 = 13607 + X² – 11219.5 – 61.14 X – 0.0833 X²
0.92 X² – 61.14 X + 633.1 = 0
This is solved by finding the two values of X that satisfy the equation.
The solution requires solving the quadratic formula,
X12 = (-b ± √(b² - 4ac)) / 2a
The values are:
X1 = 12.83
X2 = 53.62
Since we know that the value is 25 or less, the answer is 12.83
The twelfth data point in the data set is x = 16.32
How to find the aditional point?
Let x be the value of the twelfth data point. We know that the sample standard deviation of the 12 points is 12.091. We can use the following formula to calculate the sample standard deviation:
s = √((Σ((xₙ - M)²) / (n - 1)))
where:
s is the sample standard deviationxₙ is the value of the n-th data pointM is the sample meann is the number of data pointsWe can plug in the given values to get the following equation:
if x is the missing data point then:
M = (25 + 41 + 49 + 25 + 30 + 13+ 31 + 34 + 27 + 54 + 38 + x)/12
M = 30.6+ x/12
And we know that:
s = 12.091
n = 12
Replacing these values we get:
12.091 = √((Σ((xₙ - 30.6 - x/12)²) / (12 - 1)))
Apply the square in both sides:
146.19 = (Σ((xₙ - 30.6 - x/12)²) / (11)
Multiply both sides by 11:
146.19*11 = Σ((xₙ - 30.6 - x/12)²
1,608.12 = Σ((xₙ - 30.6 - x/12)²
Now we can solve the right side:
1,608.12 = (-5.6 - x/12)² + (10.4 - x/12)² + (18.4- x/12)² + (-5.6 - x/12)² + (-0.6 - x/12)² + (-17.6 - x/12)² + (0.4 - x/12)² + (3.4 - x/12)² + (-3.6 - x/12)² + (23.4 - x/12)² + (7.4 - x/12)² + ( x - x/12)²
Now we can graph this, the positive solution is x = 16.32

Reasoning if you multiply two decimals that are less than 1,can you predict whether the product will be less thanor greater than either of the factors? Explain
Answer:
if both are positive, the result will be smaller than eitherif one is negative, the result is less than the positive number and greater than the negative number.if both are negative, the result is greater than eitherStep-by-step explanation:
The magnitude of a fraction of a fraction (their product) is always smaller than the magnitudes of either fraction. So, if both decimals are positive, the result is less than either factor.
___
Negative numbers are less than 1, so there can be several cases of interest when one or both numbers are negative.
Both numbers negative
The product will be positive, so will be greater than either negative factor.
__
One number negative, the other number positive
The product will be negative, so will be less than the positive factor and greater than the negative factor. (Multiplying a negative number by a positive fraction moves it closer to zero on the number line, hence to a value that is greater than the negative factor.)
What is an extraneous solution? a solution that was found due to an arithmetic error a solution that satisfies the original equation an apparent solution that is not a real number an apparent solution that does not satisfy the original equation
Answer:
an apparent solution that does not satisfy the original equation
Step-by-step explanation:
Usually, an extraneous solution is introduced by the solution process. Sometimes it takes the form of multiplying an equation by 0, often the result of eliminating the denominators of rational functions.
Other times, it takes the form of adding branches to a function that are unintended or undefined. (Squaring a square root will often introduce "solutions" that require the square root to be a negative value.) The attached graph shows that x=4 is an extraneous solution to ...
√x = x-6
It shows up when the equation is squared:
x = x² -12x +36 ⇒ (x -9)(x -4) = 0
The "solution" x=4 is extraneous because it does not satisfy the original equation.
As in this graphed example, using graphical methods to find solutions can often avoid extraneous solutions.

We can say P(survival) = 0.9986 and thus P(not survival) = 1 - P(survival) = 1-0.9986 = 0.0014
Also,
In case 33 year old doesn't live, the payment would be 100,000 - 182 = $99,818
And
In case 33 year old lives, the payment is
-$182
We know, the expected value is the sum of the product of each possibility with its probability.
[tex]ExpectedValue=\Sigma x*p(x)=(99818)(0.0014)+(-182)(0.9986)=-42[/tex]
This means a loss of $42 (or -$42)

To simplify an algebraic expression, eliminate denominators, distribute factors, rearrange and combine like terms, and isolate the variable. Checking the reasonableness of the answer is also important after simplification.
Explanation:To simplify an algebraic expression or equation involving variables, you should first look at what needs to be solved for and then work the problem out using only variables. This helps in minimizing calculation time and reducing the chance of errors. Here are some steps to simplify algebraic expressions:
Eliminate denominators by multiplying through by the Least Common Denominator.Remove parentheses by distributing any factors outside the parentheses through the terms inside.Get all variable terms on one side of the equation by adding or subtracting them.Combine like terms or factor out the variable if it appears in more than one term to simplify further.Isolate the variable (solve for the variable) using multiplication or division as needed.Additionally, by variable rescaling and setting some limits for the error margin, you can further simplify the algebra by eliminating as many parameters as possible. Always check your final answer to ensure it's reasonable.

Answer:
E. 22Step-by-step explanation:
Look at the picture.
The lines l and m are parallel, therefore alternate interior angles are congruent.
Therefore [tex]\beta=50^o[/tex]
Supplementary angles add up to 180°.
Therefore
[tex](5x-16)+\theta=180[/tex] add 16 to both sides
[tex]5x+\theta=196[/tex] subtract 5x from both sides
[tex]\theta=196-5x[/tex]
We know: the sum of the triangle angle measures is 180°.
Therefore we have the equation:
[tex]50+2x+196-5x=180\\\\-3x+246=180\qquad\text{subtract 246 from both sides}\\\\-3x=-66\qquad\text{divide both sides by (-3)}\\\\x=22[/tex]
An explorer is caught in a whiteout (in which the snowfall is so thick that the ground cannot be distinguished from the sky) while returning to base camp. He was supposed to travel due north for 5.3 km, but when the snow clears, he discovers that he actually traveled 8.5 km at 54o north of due east. (a) How far and (b) in what direction (south of due west) must he now travel to reach base camp?
Answer:
(a) He must travel 5.25 km
(b) 17.7° south of west
Step-by-step explanation:
(Please see attached file)
1. He was supposed to travel 5.3 km due north to return to base camp
(vector S)
S = (Sx, Sy)
Sx= 0
Sy= 5.3
2. He discovers that he actually traveled 8.5 km at 54° north of due east (vector D)
D= (Dx, Dy)
Dx= Dcos Ф = 8.5cos54° = 5.0
Dy= Dsen Ф = 8.5sen54° = 6.9
3. He now needs to reach the base camp. Then, we need to find vector R.
From vectors addition/subtraction:
S = D + R
R = S - D
R= (Rx, Ry)
Rx = Dx - Sx = 0 - 5.0 = -5.0
Ry = Dy - Sy = 5.3 - 6.9 = -1.6
Magnitude of R = [tex]\sqrt{Rx^{2}+Ry^{2} }[/tex]
Magnitude of R = [tex]\sqrt{(-5.0)^{2}+(-1.6)^{2} }[/tex]
Magnitude of R = 5.25 km
Direction:
tanβ = [tex]\frac{Ry}{Rx}[/tex]
tanβ = [tex]\frac{1.6}{5.0}[/tex]
tanβ = 0.32
β = tan-1 (0.32)
β= 17.7° south of west
Sonya drops a marble while standing on a deck 7 7/8 feet above the ground. The marble falls 4 1/4 feta from Sonya's hand to the deck, and then rolls and falls to the ground. What is the total vertical distance that the marble falls?
Answer: just subtract 7 7/8 - 4 1/4 :)
Step-by-step explanation:
The distance that we can say that the marbel has fallen through is 3 5/8 feet
What is the distance of the fall?To subtract fractions, the denominators (the bottom numbers) of the fractions you're subtracting must be the same. If they're not already the same, you'll need to find a common denominator. If the fractions have different denominators, convert both fractions to an equivalent fraction
We have that;
Distance dropped = 7 7/8
Distance where the fall stopped = 4 1/4
Distance of the fall = 7 7/8 - 4 1/4
3 7 - 2/8
= 3 5/8 feet
