Imagine you draw a straight line down the middle of a piece of paper. This line is the line of symmetry. Anything you draw on one side of the line is going to have a mirror image on the other side of the line that looks exactly the same.

Now, if you have a point on the line of symmetry, that means the point is exactly in the middle of the line. And since the line is the same on both sides, that means the point is going to be the same on both sides too! So, the point on the line of symmetry stays in the same place and looks the same on both sides of the line.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

The mailbox is splitted into two shapes.

One is rectangle and the other is hemisphere.

Length of the rectangle = 2.4 ft

Width of the rectangle = 1.5 ft

Height of the rectangle = 3 ft

Surface area of the given rectangle

                  = 2(lw + wh + lh) – lw

                  = 2(2.4 × 1.5 + 1.5 × 3 + 2.4 × 3) – (2.4 × 1.5)

                  = 2(3.6 + 4.5 + 7.2) – 3.6

                  = 2(15.3) – 3.6

                  = 27

Surface area of the given rectangle = 27 square feet

Radius of the hemisphere = 1.2 ft

Curved surface area of hemisphere

                 = 2*pi*r^2

                  = 9.0432 square feet

Curved surface area of hemisphere = 9.0432 square feet                                      

Total surface area of the mailbox  = 27 + 9.0432

                                                        = 36.0432 square feet

To find how many quarts are needed to cover the mailbox.

1 Quart covers = 10 square feet

36.0432 sq. ft = 36.0432 ÷ 10

                      = 3.60432 quarts

                      ≈ 4 quarts (approximately)

Hence Kenny need to buy 4 quarts.

Cost of 1 quart = $3.50

Cost of 4 quart = 4 × 3.50

                        = 14

Hence it cost $14.

The requried, percentage of students who study less than 2.50 hours a day is approximately 25.14 percent.

A Z-score is stated as the fractional model of data point to the mean using standard deviations.

We need to convert 2.50 hours to a standard score (z-score) using the formula,

z = (x - μ) / σ

where x is the value we want to convert, μ is the mean, and σ is the standard deviation.

z = (2.50 - 3.00) / 0.75

z = -0.67

This means that 2.50 hours is 0.67 standard deviations below the mean.

We can use a standard normal distribution table or a calculator to find the percentage of the distribution that falls below this standard score. For example, using a standard normal distribution table, we can look up the area to the left of z = -0.67 and get:

P(z < -0.67) = 0.2514

So the correct answer is (a) 25.14 percent.

Answer:

To determine how much the tourist will receive while leaving Nepal, we need to know the total cost of the 5 Nepali caps including VAT, and then subtract any taxes or fees that the tourist may have paid when purchasing the caps.

Given that the tourist bought 5 Nepali caps at a cost of Rs 452 per piece including VAT, we can calculate the total cost of the caps as:

Total cost of 5 Nepali caps = 5 x Rs 452 = Rs 2260

Since the cost already includes VAT, we do not need to add any additional taxes or fees.

Therefore, if the tourist does not make any additional purchases or incur any other expenses while in Nepal, they will receive back Rs 2260 when leaving Nepal.

Your statement is partially correct congruent .

Two triangles are similar if they have all three corresponding angles congruent or equal in measure, or if they have two corresponding angles congruent and the corresponding sides are in proportion (i.e., the ratio of the length of one side to the length of the corresponding side in the other triangle is constant). This is known as the Angle-Angle Similarity Theorem (AA Similarity), or the Angle-Side-Angle Similarity Theorem (ASA Similarity).

It is important to note that if only one pair of corresponding angles is congruent, the triangles are not necessarily similar. For example, two right triangles with one acute angle congruent are not necessarily similar, since the other acute angles are not congruent. Similarly, if two triangles have all three sides in proportion, they are not necessarily similar unless all three corresponding angles are also congruent.

Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).

We are given;

The two arguements

Now,

A). The argument is valid. This is an example of the disjunctive syllogism, which is a valid form of argument. If we have a disjunction "A or B", and we know that A is false, then we can conclude that B must be true. In this case, "she will go to school or she will get a job" is the disjunction, and "she will not get a job" tells us that "she will not get a job" is true. Therefore, we can conclude that "she will go to school" must be true.

B). The argument is invalid. This is an example of the fallacy of affirming the consequent. The conditional statement "if Cathy is a gambler, then she lives in Marine" tells us that if Cathy is a gambler, then she lives in Marine. However, it does not tell us anything about whether Cathy is a gambler or not.

Step-by-step explanation:

In preparing to construct a one-sample t interval for a population mean, suppose we are not sure if the population distribution is Normal. In option (c) A boxplot of the data has a large outlier, we would not be safe constructing the interval based on an SRS of size 24 from the population.

What is a sample?

A sample is characterised as a more manageable and compact version of a bigger group. A smaller population that possesses the traits of a bigger group. When the population size is too big to include all participants or observations in the test, a sample is utilised in statistical analysis.

Constructing a one-sample t interval for a population mean is generally safe when the population is not Normal, as long as the sample size is large enough (usually at least 30) or the sample is taken from a population that is not too skewed or has outliers.

Therefore, options (a), (b), and (e) suggest that the sample may come from a population that is roughly Normal or can be transformed to be Normal, and so constructing the interval based on an SRS of size 24 would be safe.

Option (d) suggests that the sample standard deviation is large, but this does not necessarily mean that constructing the interval would not be safe.

It may reduce the precision of the interval, but as long as the sample size is sufficient, the interval can still be constructed.

Option (c) suggests that the sample has a large outlier, which may significantly affect the distribution of the sample and the calculation of the interval.

Therefore, in this circumstance, constructing the interval based on an SRS of size 24 would not be safe.

Answer:

x = 40° , y = 43° , z = 97°

Step-by-step explanation:

∠ DAC = y = ∠ ACB = 43°

• opposite angles in a parallelogram are congruent , then

z = ∠ D = 97°

the sum of the 3 angles in Δ ACD = 180° , that is

x + y + 97° = 180°

x + 43° + 97° = 180°

x + 140° = 180° ( subtract 140° from both sides )

x = 40°

x = 40° , y = 43° , z = 97°

Answer:

Step-by-step explanation:

Let's assume that the amount invested at 10% is x, and the amount invested at 5% is (60000 - x), since the total investment is $60,000.

The interest earned on the 10% investment after one year would be 0.10x, and the interest earned on the 5% investment after one year would be 0.05(60000 - x).

We are given that the interest earned by the two accounts is equal, so we can set up an equation:

0.10x = 0.05(60000 - x)

Simplifying this equation, we get:

0.10x = 3000 - 0.05x

Adding 0.05x to both sides, we get:

0.15x = 3000

Dividing both sides by 0.15, we get:

x = 20000

Therefore, the amount invested at 10% is $20,000, and the amount invested at 5% is ($60,000 - $20,000) = $40,000.

To check that the interest earned is equal for both investments, we can calculate:

Interest earned on 10% investment = 0.10($20,000) = $2,000

Interest earned on 5% investment = 0.05($40,000) = $2,000

As expected, the interest earned on both investments is equal.

Both Student A and Student B's representations of the expression 9/y³ⁿ are incorrect.

In mathematics, an expression is a combination of numbers, symbols, and/or variables that are arranged in a meaningful way. An expression can represent a value, a quantity, a function, or some other mathematical object. Expressions can be made up of one or more terms. A term is a group of numbers, symbols, and/or variables that are separated by a plus or minus sign. Expressions can also include mathematical operations, such as addition, subtraction, multiplication, and division, as well as exponents and parentheses. Expressions are used in various areas of mathematics, including algebra, calculus, and statistics, to represent mathematical relationships and to solve problems.

Here,

Student A represents the expression as the product of 9 and y times the product of 3 and t, which can be written as: 9 * y * 3 * t = 27yt.

This representation is incorrect because it does not include the exponent 3 in the denominator. The correct representation of the expression is: 9 / y^3t.

Student B represents the expression as the quotient of 9 and y times the sum of 3 and t, which can be written as: 9 / y * (3 + t) = (27 + 9t) / y.

This representation is also incorrect because it incorrectly combines the sum of 3 and t in the denominator. The correct representation of the expression is: 9 / y^3t.

To represent the expression correctly, we need to include the exponent 3 in the denominator, indicating that y is being raised to the power of 3, and include t as a separate factor in the denominator. Therefore, the correct representation of the expression is: 9 / (y^3 * t).

Answer:

Using the ratio given, we know that for every 5 colored pencils, there are 2 markers in each box.

Therefore:

The first blank represents the number of colored pencils in the box. Since the ratio of colored pencils to markers is 5 to 2, we can calculate that there are 5 colored pencils for every 2 markers. This means that for each box, there are 5/7 of the total number of items are colored pencils. So the missing value in the first row is 25.

The second row indicates that there are 20 items in the box. We know that the first row (colored pencils) has 25 items, and since the total number of items in the box is 20, the missing value in the second row (markers) is 20 - 25/5 = 15.

The third row represents the total number of colored pencils and markers in each box. We know that there are 25 colored pencils and 15 markers in each box, so the total number of items in each box is 40.

Step-by-step explanation:

To find the equilibrium quantity and equilibrium price for the demand and supply functions, we need to find the point where the quantity demanded and the quantity supplied are equal. This point is known as the equilibrium point and is represented by the intersection of the demand and supply curves.

The demand function is given by p = -0.1q²-0.2q+9, and the supply function is given by p = 0.2q²+0.4q+1.8.

To find the equilibrium quantity, we need to set the quantity demanded equal to the quantity supplied:

-0.1q²-0.2q+9 = 0.2q²+0.4q+1.8

Simplifying and rearranging the terms, we get:

0.3q² + 0.6q - 7.2 = 0

Using the quadratic formula, we can solve for q:

q = (-0.6 ± √(0.6² - 4(0.3)(-7.2))) / (2(0.3))

q = (-0.6 ± √(0.6² + 8.64)) / 0.6

q = (-0.6 ± √9.36) / 0.6

q = (-0.6 ± 3.06) / 0.6

q = 4.6, -5.0

Since the quantity cannot be negative, the equilibrium quantity is q = 4.6.

To find the equilibrium price, we can substitute the equilibrium quantity into either the demand or supply function:

p = 0.2q²+0.4q+1.8

p = 0.2(4.6)²+0.4(4.6)+1.8

p = 7.82

Therefore, the equilibrium quantity is 4.6 units and the equilibrium price is $7.82.

The remainder theorem can be used to determine the volume of a cage with a 15-inch height since b = 15, which results in a volume of 2160 inch3.

The size of an item in 3 directions is the area that is covered by its boundaries. The amount of room an object occupies in three aspects is measured by its height, which is given in cubic inches. A few of illustrations of cubic units are cm3 and in3. On the other perspective, an item's mass is used to measure what more matter it contains. The typical method to ascertain an object's mass is to weigh it, either in pounds or kilograms. Unlike the fundamental equations for the area of a rectangular box, which is length, breadth, and height, the primary equation for volumes is length, width, and height.

Simplifying, the exponents expression, we have 63y/xu⁴

Exponents are the powers to which a particular number is raised.

Given the expression 3y⁻⁴ . 3y⁵x⁸u⁻⁵.7x⁻⁹. To simplify the expression, we use the product rule of exponents which states that for a given base x, xᵃ xᵇ = xᵃ⁺ᵇ.

So, applying this rule to the expression and collecting common bases, we have that

3y⁻⁴ . 3y⁵x⁸u⁻⁵u.7x⁻⁹ = 3y⁻⁴ × 3y⁵ × x⁸ × 7x⁻⁹ × u⁻⁵ × u

= 3 × 3 × y⁻⁴ × y⁵ × 7 × x⁸ × x⁻⁹ × u⁻⁵ × u

Applying the product rule, we have that

= 3 × 3 × y⁻⁴ ⁺ ⁵ × 7 × x⁸ ⁺(⁻⁹) × u⁻⁵ ⁺ ¹

= 3 × 3 × y⁻⁴ ⁺ ⁵ × 7 × x⁸ ⁻ ⁹ × u⁻⁵ ⁺ ¹

= 3 × 3 × y × 7 × x⁻¹ × u⁻⁴

= 3 × 3 × 7 × y × x⁻¹ × u⁻⁴

Using the reciprocal rule that x⁻ⁿ = 1/xⁿ, we have that
