Answer:
To find the set (AUB)' n C, we first need to find the union of sets A and B, which is the set of all elements that belong to either A or B or both:
AUB = {1, 2, 3, 5, 6}
The complement of AUB, denoted by (AUB)', is the set of all elements in U that do not belong to AUB:
(AUB)' = {4, 7, 8}
Next, we need to find the intersection of (AUB)' and C, which is the set of all elements that belong to both (AUB)' and C:
(AUB)' n C = {1}
Therefore, the set (AUB)' n C contains only the element 1.

The equation a² + b² = c² represents the Pythagorean theorem.
What is the Pythagorean theorem?This is a theorem that states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b).
The Pythagorean theorem is used to find the length of one of the sides of a right-angled triangle when the lengths of the other two sides are known.
To solve the problem, you need to have at least two side lengths given. Then, you can use the equation to find the length of the third side. For example:
If you know the lengths of sides a and b and need to find the length of the hypotenuse (c):
Plug in the known values for a and b into the equation and solve for c.
Example: If a = 3 and b = 4, then 3² + 4² = c², which gives 9 + 16 = c², so c² = 25, and c = sqrt(25) = 5.

Find the area of the trapezoid. 10 km 8 km 6 km
the area of the trapezoid is 10√3 km² (approximately 17.3 km²).To find the area of a trapezoid, we use the formula A = (1/2) * (b₁ + b₂) * h
what is trapezoid ?
A trapezoid is a quadrilateral with at least one pair of parallel sides. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs. The height (or altitude) of a trapezoid is the perpendicular distance between the two bases. The formula for the area of a trapezoid
In the given question,
To find the area of a trapezoid, we use the formula:
A = (1/2) * (b₁ + b₂) * h
where A is the area, b₁ and b₂ are the lengths of the parallel sides of the trapezoid, and h is the height (or perpendicular distance between the parallel sides).
In this case, we are not given the height, but we can still find the area if we make some assumptions. Let's assume that the trapezoid is isosceles, which means that the two non-parallel sides are equal in length. Then we can draw an altitude from one of the vertices to the opposite base, which will bisect the base and create two right triangles.
Using the Pythagorean theorem, we can find the length of the altitude:
a² + (b₁ - b₂)² = (2a)²
Simplifying and solving for a, we get:
a² + (b₁- b₂)² = 4a²
3a² = (b₁ - b₂)²
a = (1/√3) * |b₁ - b₂|
Since we know that the sum of the non-parallel sides is 10 km, we can write:
b₁ + b₂ = 10
Let's assume that b1 is the longer base, so we can write:
b₁ = 8 km
b₂ = 10 - b₁ = 2 km
Substituting these values into the formula for the altitude, we get:
a = (1/√3) * |8 - 2| = (1/√3) * 6 = 2√3 km
Now we can use the formula for the area of a trapezoid to find the area:
A = (1/2) * (b1 + b2) * h
A = (1/2) * (8 + 2) * 2√3
A = 10√3 km²
Therefore, the area of the trapezoid is 10√3 km² (approximately 17.3 km²).

(1) The value of X is equal to 4 (2) The mean age is 3. (3) The probability of randomly selecting a child under the age of 9 is approximately 0.83.
How to calculate the average?
The formula for calculating the average of given numbers is equal to the sum of all values divided by the total number of values. There are three main types of averages: mean, median, and mode. All of these techniques work slightly differently and often give slightly different typical values.
(i). Given that there are a total of 42 children on the birthday, finding the value of x:
2x + 3x (4x-1) + x + (x-2) + (x-3) = 42
11x - 6 = 42
11x = 48
x = 4
Therefore, the value of x is equal to 4.
(ii). To find the average age, we need to calculate the sum of all the ages and divide by the total number of children:
Average age = (7 x 2 + 8 x 3 + 9 x (4-1) +10 x 4 +11 x (4-2) 12 x (4-3)) / 42
= (14 + 24 + 27 + 40 + 22 +12) / 42
= 139/42
= 3.31
Rounded to the nearest whole number, the average age is 3.
(iii). The probability of randomly selecting a child under 9 is obtained by adding the number of children aged 7, 8 or 9 (because we want children under 9) and dividing by the total number of children:
Number of children under 9 years = 2x + 3x + (4x-1)
Number of children under 9 years = 9x - 1
Number of children under 9 = 9(4)–1
Number of children under 9 years = 35
Probability of choosing a child under 9 = number of children under 9 / total number of children
Probability of choosing a child under 9 = 35/42
The probability of choosing a child under 9 years old is ≈ 0.83
Thus, the probability of randomly selecting a child under the age of 9 is approximately 0.83.

3 gal. of an alcohol solution was mixed
with 2 gal. of a 65% alcohol solution to
make a 41% alcohol solution. Find the
percent concentration of the first solution.
Therefore, the percent concentration of the first solution is 25%.
Let's call the percent concentration of the first solution x.
When we mix the two solutions, we end up with a total of 3 + 2 = 5 gallons of the new solution.
We can start by writing an equation based on the amount of pure alcohol in each solution:
[tex]3x + 2(0.65) = 5(0.41)[/tex]
The left side of the equation represents the total amount of pure alcohol in the mixture. The first term, 3x, represents the amount of pure alcohol in the 3 gallons of the first solution. The second term, 2(0.65), represents the amount of pure alcohol in the 2 gallons of the second solution.
The right side of the equation represents the total amount of pure alcohol in the final 5-gallon mixture, which is the product of the 41% concentration and the 5 gallons of the mixture.
Simplifying the equation, we get:
[tex]3x + 1.3 = 2.05[/tex]
Subtracting 1.3 from both sides, we get:
[tex]3x = 0.75[/tex]

Larry Mitchell invested part of his $20,000 advance at 3% annual simple interest and the rest at 6% annual simple interest. If his total yearly interest from both accounts was $990, find the amount invested at each rate.
Larry Mitchell invested $ [tex]7000[/tex] at [tex]3[/tex]% annual simple interest and $[tex]13000[/tex] at [tex]6[/tex]% annual simple interest.
What is the annual simple interest?Let's denote the amount Larry Mitchell invested at 3% annual simple interest as "x" (in dollars) and the amount he invested at 6% annual simple interest as [tex]"20,000 - x"[/tex] (since he invested the rest of the advance amount).
The formula for simple interest is:
Simple Interest (SI) = Principal (P) * Rate (R) * Time (T)
Given that the total yearly interest from both accounts was $990, we can set up the following equation:
3% of x + 6% of [tex](20,000 - x) = 990[/tex]
Converting the percentages to decimals, we get:
[tex]0.03x + 0.06(20,000 - x) = 990[/tex]
Now, we can solve for x by simplifying the equation and isolating x on one side:
[tex]0.03x + 1200 - 0.06x = 990[/tex]
[tex]-0.03x = 990 - 1200[/tex]
[tex]-0.03x = -210[/tex]
Dividing both sides by -0.03, we get:
x = (-210)/(-0.03)
[tex]x = 7000[/tex]
So, Larry Mitchell invested $7000 at 3% annual simple interest.
Substituting the value of x back into the equation, we can find the amount he invested at 6% annual simple interest:
[tex]20,000 - x = 20,000 - 7000 = 13000[/tex]
Therefore, Larry Mitchell invested $ [tex]7000[/tex] at [tex]3[/tex]% annual simple interest and $[tex]13000[/tex] at [tex]6[/tex]% annual simple interest.

Select the point on the number line that best approximates the location of √14
Answer:
To approximate the location of the square root of 14 on a number line, we can first find the two integers that √14 is between. We know that:
3^2 = 9 < 14 < 16 = 4^2
So √14 is between 3 and 4. We can divide the distance between 3 and 4 into equal parts and estimate the location of √14 based on where it falls in that interval.
Dividing the interval into 10 equal parts, we get:
3.0 - 3.1 - 3.2 - 3.3 - 3.4 - 3.5 - 3.6 - 3.7 - 3.8 - 3.9 - 4.0
Since √14 is closer to 3 than to 4, we can estimate its location as being closer to 3.4 than to 3.5. Therefore, a good approximation for the location of √14 on the number line is 3.7.

Describe at least two differences between constructing parallel lines and constructing perpendicular lines.
By using the compass to measure a distance from the original line, and then transferring that distance to another point on the line, a parallel line can be drawn.
What is the parallel lines?
Parallel lines are two lines in a plane that never intersect.
1. Orientation of Lines:
Parallel lines are lines that never intersect and remain equidistant from each other at all points.
When constructing parallel lines, the lines are drawn in the same direction and maintain the same distance between them throughout their entire length. They do not meet or cross each other.
On the other hand, perpendicular lines are lines that intersect at a right angle (90 degrees). When constructing perpendicular lines, the lines are drawn so that they intersect at a right angle, forming four right angles at the point of intersection.
2. Tools/Methods Used:
Constructing parallel lines and constructing perpendicular lines may require different tools or methods.
To construct parallel lines, one common method is to use a straightedge and a compass. A straightedge is used to draw a straight line, and a compass is used to measure and transfer distances to create additional parallel lines.

What is the standard normal distribution?The region where [tex]z > 1.42[/tex] in the standard normal distribution corresponds to the area under the curve to the right of [tex]1.42[/tex] on the z-axis.
To find this area, we can use a standard normal distribution table or a calculator with a cumulative distribution function (CDF) for the standard normal distribution.
Using a calculator with a CDF for the standard normal distribution, we can input 1.42 and calculate the area to the left of 1.42. Then, we subtract this area from 1 to get the area to the right of 1.42. Here's the calculation:
[tex]P(Z > 1.42) = 1 - P(Z < 1.42)[/tex]
Using a standard normal distribution table or a calculator, we find that [tex]P(Z < 1.42)[/tex] is approximately 0.9207. Subtracting this value from 1, we get:
[tex]P(Z > 1.42) \approx 1 - 0.9207 \approx 0.0793[/tex]

Rounding is the process of approximating a number to a nearby value that is easier to work with or more appropriate for a given context. When rounding, we take a number with many decimal places or significant figures and adjust it to a simpler or more convenient value with fewer decimal places or significant figures.
In the given question,
Yes, each number is rounded correctly to the nearest hundred thousand based on the rules of rounding.
To round to the nearest hundred thousand, we look at the digit in the hundred thousand place and the digit to its right (i.e., in the ten thousand place).
If the digit in the ten thousand place is 5 or greater, we round up the digit in the hundred thousand place by adding 1.
If the digit in the ten thousand place is less than 5, we leave the digit in the hundred thousand place as it is.
Using these rules, we can see that:
350000 rounded to the nearest hundred thousand is 400000 because the digit in the ten thousand place is 5, so we round up the digit in the hundred thousand place.
555555 rounded to the nearest hundred thousand is 560000 because the digit in the ten thousand place is 5, so we round up the digit in the hundred thousand place.
137998 rounded to the nearest hundred thousand is 200000 because the digit in the ten thousand place is 7, so we round up the digit in the hundred thousand place.
792314 rounded to the nearest hundred thousand is 800000 because the digit in the ten thousand place is 3, so we leave the digit in the hundred thousand place as it is.

The circle graph below shows the number of animals in Mushu's farm. Sheep Donkeys Camels Goats Cows If there were 24 goats, how many cows are there in the farm?
By assuming that the farmer has goat and cows in the ratio 3:4, the number of cows in the farm will be 32 cows.
If there were 24 goats, how many cows are there in the farm?To find out how many cows are in the farm, we need to know the total number of animals in the farm. Assuming the ratio of goats to cows is 3:4, we can write this as: [tex]3x : 4x[/tex]
Where 3x represents the number of goats, and 4x represents the number of cows. If we know that there are 24 goats, we can set up an equation to solve for x:
3x = 24
Dividing both sides by 3, we get:
x = 8
Now that we know the value of x, we can find the number of cows:
= 4x
= 4(8)
= 32
Therefore, there are 32 cows in the farm.

The fraction of the panel left after cutting the hole is 11/12.
The correct answer choice is option C
What is the fraction of the panel is left?Fraction left = (area of panel) - (area of hole) / (area of panel
Area of panel = 3 feet × 2 feet
= 6 square feet
Area of hole = 1 foot × ½ foot
= ½ square foot
So,
Fraction left = (area of panel) - (area of hole) / (area of panel
= (6) - (½) / (6)
= (5½) / (6)
= 11/2 ÷ 6
multiply by the reciprocal of 6
= 11/2 × 1/6
= 11/12
Ultimately, the fraction left is 11/12
