What is a Parallelogram?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
Given is a parallelogram as shown in the image.
Opposite angles of a parallelogram are equal. So, we can write -
x + 50 = y
y - x = 50 .... Eq { 1 }
Sum of the angles of a quadrilateral are 360°. We can write -
2(x - 30) + (x + 50) + y = 360 .... Eq { 2 }
2x - 60 + x + 50 + y = 360
3x + y = 370
3x + 50 + x = 370
4x = 320
x = 80
y = 130
Therefore, the measure of {x} and {y} are 80 and 130 respectively.

The sides n and s of the given similar triangles are 12 and 10 respectively.
What are similar triangles?
If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are similar. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.
The polygon with three sides is a triangle. The prerequisites for a triangle's similarity are that the corresponding angles on both triangles must be equal, and the corresponding sides must be proportional to one another.
In the given figure both triangles are similar triangles.
So according to the properties of similar triangles,
[tex]\frac{15}{s} = \frac{9}{6}=\frac{n}{8}[/tex]
Solving the above equations,
15/s = 9/6
s = 10
n/8 = 9/6
n = 12
Therefore the sides n and s of the given similar triangles are 12 and 10 respectively.

Answer:
Step-by-step explanation:
The expression "11 increased by twice Grogan's height" can be written as:
11 + 2Grogan's height
For example, if Grogan's height is 5 feet, the expression would be:
11 + 2(5) = 11 + 10 = 21
What percent of 112 is 21?
21 is 18.75% of 112. Percentage is widely used to represent a difference or contrast between two numbers.
What do you mean by percentage?A percentage is a way to express a number as a fraction of 100. It is often used to express a change or a comparison between two numbers. The symbol for percentage is %, and it represents the fraction of 100. For example, 50% means 50 out of 100, or 1/2.
Percentages are often used to represent increases or decreases in a quantity, as well as ratios and proportions. For example, if the price of a product increases by 20%, it means the new price is 120% of the original price, or 1.2 times the original price. If a student scores 80% on a test, it means they answered 80 out of 100 questions correctly.
Percentages can be easily converted to decimals or fractions by dividing by 100. For example, 50% can be written as 0.5 as a decimal or 1/2 as a fraction. Similarly, 75% can be written as 0.75 as a decimal or 3/4 as a fraction.
To find what percent 21 is of 112, we can use the formula:
Percent = (Part ÷ Whole) x 100
In this case, the part is 21 and the whole is 112, so:
Percent = (21 ÷ 112) x 100
Percent = 0.1875 x 100
Percent = 18.75
Therefore, 21 is 18.75% of 112.

rs when constructing a confidence interval for a difference between two population proportions, why is it important to check that the number of successes and the number of failures in each sample is at least 10?
It is important to check that the number of successes and number of failures in each sample is at least 10 because this helps ensure that the normal approximation of the binomial distribution is accurate.
When constructing a confidence interval for the difference between two population proportions, it is important to check that the number of successes and the number of failures in each sample is at least 10 because this helps ensure that the normal approximation of the binomial distribution is accurate. The normal approximation is often used in constructing confidence intervals for proportions because it simplifies the calculations, but it is only accurate if the sample size is large enough.
A common rule of thumb is that each sample should have at least 10 successes and 10 failures in order to ensure that the normal approximation is reasonable. This is because the Central Limit Theorem states that the sum of many independent and identically distributed random variables will approximately follow a normal distribution. When the sample size is large enough, the distribution of the sample proportions will be approximately normal, even if the individual observations are not.
If the number of successes and failures in each sample is less.

Answer:
735/420 + 2 = 735/420 + 420/420 = 1155/420
Step-by-step explanation:
To add the three fractions, we need to find a common denominator. A common denominator for all three fractions is 420:
30/15 = 2
25/40 = 25/40 * 3/3 = 75/120
30/35 = 30/35 * 12/12 = 360/420
Adding the three fractions with the common denominator:
2 + 75/120 + 360/420 = 2 + 375/420 + 360/420
Combining like terms:
2 + 735/420 = 2 + 735/420
The answer is 735/420 + 2 = 735/420 + 420/420 = 1155/420.
A child's toy is in the shape of a square pyramid. The pyramid stands 20 inches tall and each side of the base measures 24 inches.
Half of the surface area of the pyramid is black and the remainder is yellow.
What is the surface area of the toy that is yellow?
Enter your answer, rounded to the nearest tenth, in the box.
The surface area of the toy that is yellow is 847.8 inches², to the nearest tenth.
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
A square pyramid is a three dimensional object with one square base and 4 four triangular lateral faces.
Total surface area of the pyramid = Area of the base + 4(area of triangular face)
Base length = 24 inches
Base area = 24² = 576 inches²
Height of the pyramid = 20 inches
The slant height, l of the triangle can be found as,
l = [tex]\sqrt{(\frac{a}{2} )^2+h^2}[/tex], where a is the length of the base and h is the height.
l = [tex]\sqrt{12^2+20^2}[/tex]
= √544
= √(34 × 16)
= 4√34 inches
Area of 4 triangular faces = 4 ([tex]\frac{1}{2}[/tex] × 24 × 4√34)
= 2 × 24 × 4√34
= 192√34 inches²
Total surface area = 192√34 inches² + 576 inches²
= (192√34 + 576) inches²
= 1695.5428 inches²
Surface area of toy that is yellow = 1695.5 / 2 = 847.8 inches², to the nearest tenth.
Hence the surface area of the yellow part of toy is 847.8 inches², to the nearest tenth.

7. (2 points) how many distinct 10-letter arrangements can be formed from the letters in the word statistics?
The number of distinct 10-letter arrangements that can be formed from the letters in the word "statistics" is 40320, which can be calculated by finding the permutation of 8 objects taken 8 at a time
Permutation is a mathematical concept that deals with counting the number of ways to arrange a set of objects in a particular order.
The number of permutations of a set of n objects taken r at a time can be calculated using the formula:
=> n! / (n - r)!.
Where "n!" represents n factorial, which is the product of all positive integers less than or equal to n.
In this case, we are going to find out the number of distinct 10-letter arrangements that can be formed from the letters in the word "statistics".
In our case, the number of objects is 8 (the letters in the word "statistics") and we are taking 10 at a time, so the formula becomes:
=> 8! / (8 - 10)! = 8! / (-2)!.
The factorial of a negative number is undefined, so this case is not possible.
Since we cannot take more objects than the number of available objects, we have to find the number of permutations of 8 objects taken 8 at a time. The formula becomes:
=> 8! / (8 - 8)! = 8! / 0! = 8!.
Finally, 8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40320,
which means that there are 40320 distinct 10-letter arrangements that can be formed from the letters in the word "statistics".

For the triangle ABC the interior angles measures ∠A = 80°, ∠B = 58°, and ∠C = 42°.
What are triangles?
Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.
According to the angles of a triangle theorem, the sum of angles of a triangle is 180°.
The measure of ∠A = 80°.
The measure of ∠B = 8x + 2.
The measure of ∠C = 6x.
The equation is -
∠A + ∠B + ∠C = 180°
Substitute the values into the equation -
80° + 8x + 2 + 6x = 180
Collect the like terms -
8x + 6x = 180 - 80 - 2
14x = 98
x = 98/14
x = 7°
So, the measure of ∠B = 8(7) + 2 = 58°
The measure of ∠C = 6(7) = 42°
The interior angles of the triangle are 80°, 58° and 42°.
