Step-by-step explanation:

The mode is just the number that is showed the most in a data set. Since 18 is showed the most 18 is the answer Hope that helps!

Answer:

18

Step-by-step explanation:

The mode is the number that appears the most in a group of numbers. 18 appears twice, while the rest of the numbers only appear once.

a) The relationship between b and c is that c cannot be zero.

b) b can be any nonzero constant and c is equal to 2.5 in this case.

In two dimensions, the compatibility equations for strain are,0

∂εx/∂y + ∂γxy/∂x = 0

∂εy/∂x + ∂γxy/∂y = 0

where εx and εy are the normal strains in the x and y directions, respectively, and γxy is the shear strain.

Using the given strain field, we can calculate the strains,

εx = -4.5cx² + 10.5cy

εy = 1.5cx² - 7.5cy²

γxy = 1.5bxy

Taking partial derivatives and plugging them into the compatibility equations, we get,

⇒ -9cx + 0 = 0

⇒ 0 + (-15cy) = 0

These equations must be satisfied for the strain field to be compatible. From the first equation,

We get cx = 0, which means c cannot be zero.

From the second equation, we get cy = 0,

Which means b can be any nonzero constant.

For part b:

We are asked to find the displacements u and v corresponding to the given strain field at points (3, 7), assuming they are zero at point (0, 0) and using c = 2.5.

To find the displacement components,

We need to integrate the strains with respect to x and y. We get,

u = ∫∫εx dx dy = ∫(10.5cy) dy = 5.25cy²

v = ∫∫εy dx dy = ∫(1.5cx² ) dx - ∫(7.5cy²) dy = 0.5cx³ - 2.5cy³

Plugging in the values of c and b, we get,

u = 5.25(2.5)(7)²  = 767.62

v = 0.5(2.5)(3)³ - 2.5(7)³ = -8583.75

Therefore,

The displacements at points (3, 7) are u = 767.62 and v = -8583.75.

Answer:

True.

Explanation:

When solving equations with unknowns on both sides, it is generally recommended to first deal with the variable terms before dealing with the constant terms. This involves simplifying the equation by combining like terms and isolating the variable on one side of the equation. Once the variable is isolated, you can then solve for its value.\(\)

The percent error for object A is 6%. The percent error for object B is 5.3%.

Percent error is a measure of the accuracy of your data collection and calculations. Percent error is determined using the following equation:% error = theoretical value | theoretical value - experimental value | × 100For two objects, the percent error should be calculated using the most accurate method of determining volume.

Here is an example: Suppose that the theoretical value of object A is 50 mL. The most accurate method for determining the volume of object A results in a measured value of 47 mL. We can then calculate the percent error using the formula:

% error = |50 - 47|/50 × 100%

error = 6%.

Let's suppose the theoretical value of object B is 75 mL. The most accurate method for determining the volume of object B results in a measured value of 71 mL. We can calculate the percent error using the formula:

% error = |75 - 71|/75 × 100%

error = 5.3%

To find the y coordinate of a point on the line y = 2x + 3 that is closest to the point (0, 7), we need to follow the steps below:

Step 1: We have the equation of the line y = 2x + 3, which can also be written in slope-intercept form as y = mx + b, where m is the slope of the line and b is the y-intercept of the line.

Step 2: Find the slope of the line by comparing its equation with y = mx + b. From the equation, we can see that m = 2.

Step 3: Since we have the slope of the line, we can find the equation of a line perpendicular to it that passes through the point (0, 7). A line perpendicular to a line with slope m has a slope of -1/m.

Therefore, the slope of the perpendicular line is -1/2.

The equation of the perpendicular line passing through (0, 7) is y - 7 = (-1/2)(x - 0).

Simplifying, we get y = -x/2 + 7.

Step 4: The point of intersection of the line y = 2x + 3 and the line y = -x/2 + 7 is the point on the line y = 2x + 3 that is closest to the point (0, 7). Solving the system of equations y = 2x + 3 and y = -x/2 + 7, we get x = 1 and y = 5.

Step 5: Therefore, the y coordinate of the point on the line y = 2x + 3 that is closest to the point (0, 7) is 5.

F(3) is equal to 9, based on the given table and the corresponding values of x and f(x). Option D.

To find the value of F(3) based on the given table, we look at the corresponding x-value of 3 and find its corresponding f(x) value.

From the table, we see that when x = 3, f(x) = 9. Therefore, F(3) = 9.

The table shows the values of x and their corresponding f(x) values. We can see that when x increases by 1, f(x) also increases by 3. This indicates that the function has a constant rate of change, where the change in f(x) is always 3 units for every 1 unit change in x.

Given that F(3) represents the value of the function when x = 3, we look at the x-values in the table and find the corresponding f(x) value. In this case, when x = 3, f(x) = 9.

Therefore, the value of F(3) is 9. Option D is correct.

The statement that is true is:

Statements 1 and 3

Let's examine each statement individually:

If n is a multiple of 8, then n is a multiple of 4. This statement is true because every number that is divisible by 8 is also divisible by 4. Since 8 is a multiple of 4, any multiple of 8 will have factors of both 8 and 4. If n is a multiple of 18, then n is a multiple of 2.

This statement is also true. Any number that is divisible by 18 is also divisible by 2 because 18 contains a factor of 2. Every multiple of 18 will have at least one factor of 2.

Statement 2 is not true. If n is a multiple of 18, then n is a multiple of 9.

This statement is false because there are numbers that are multiples of 18 but not multiples of 9. For example, 18 itself is a multiple of 18 but not a multiple of 9, as 18 divided by 9 is equal to 2.

In mathematics, an expression is a combination of symbols and/or numbers that represents a quantity or a mathematical relationship between quantities. Expressions can be simple or complex, and can involve arithmetic operations, algebraic operations, functions, and variables.

Here,

To add these mixed numbers, we need to first convert them to improper fractions with the same denominator:

7 1/4 = 28/4 + 1/4

= 29/4

4 5/12 = 48/12 + 5/12

= 53/12

Now, we can add the fractions:

=29/4 + 53/12

To find a common denominator, we can multiply the denominator of the first fraction by 3 and the denominator of the second fraction by 1:

29/4 × 3/3 = 87/12

53/12 × 1/1 = 53/12

Now we have the same denominator, so we can add the numerators:

87/12 + 53/12 = 140/12

we can infer that the firm is currently maximizing its profit. Option (b), "the firm is currently maximizing its profit," is the most appropriate inference from the provided data.

To determine whether the firm is maximizing its profit, we need to analyze the relationship between marginal revenue (MR), marginal cost (MC), and price. In a monopolistically competitive market, firms aim to maximize their profit by producing at a level of output where MR equals MC.

From the information provided, we know that the firm's marginal revenue is equal to $15 and marginal cost is also equal to $15. This indicates that the firm is producing at the level where its marginal revenue equals its marginal cost, which is a characteristic of profit maximization.

Additionally, we are told that the firm is charging the highest price it can at $30. This means that the firm is able to set its price above its average total cost, resulting in a positive difference between price and average total cost, known as economic profit.

The analytic functions f = u + iv, where u(x, y) = e^x (xsin y + ycosy), are given by f(x, y) = e^x (xsin y + ycosy) + i(-e^x (xsin y + ycosy) + g(y)), where g(y) is an arbitrary function of y.

To find all the analytic functions of the form f = u + iv, where u(x, y) = e^x (xsin y + ycosy), we need to use the Cauchy-Riemann equations. The Cauchy-Riemann equations state that for a function f(x, y) = u(x, y) + iv(x, y) to be analytic, the following conditions must be satisfied:

∂u/∂x = ∂v/∂y

∂u/∂y = -∂v/∂x

Let's calculate these partial derivatives and solve the equations:

Given u(x, y) = e^x (xsin y + ycosy)

∂u/∂x = e^x (sin y + ycos y)

∂u/∂y = e^x (xcos y - ysin y)

Let's equate these with the partial derivatives of v(x, y):

∂v/∂y = ∂u/∂x = e^x (sin y + ycos y)

∂v/∂x = -∂u/∂y = -e^x (xcos y - ysin y)

Integrating these equations with respect to x and y, we get:

v(x, y) = -e^x (xsin y + ycosy) + g(y)

v(x, y) = -e^x (xsin y + ycosy) - h(x)

Where g(y) and h(x) are arbitrary functions of y and x, respectively.

Therefore, the analytic functions of the given form are:

f(x, y) = u(x, y) + iv(x, y) = e^x (xsin y + ycosy) + i(-e^x (xsin y + ycosy) + g(y))

where g(y) is an arbitrary function of y.

The correct answer is option C, when the distribution of the data is approximately symmetric and bell-shaped.

According to the Empirical Rule, also referred to as the 68-95-99.7 Rule, for a normal distribution, roughly 68% of the data will lie within one standard deviation of the mean, 95% of the data will lie within two standard deviations of the mean, and 99.7% of the data will lie within three standard deviations of the mean.

Only when the distribution of the data is symmetric and bell-shaped does this rule hold.

The Empirical Rule cannot be used to estimate percentages if the data is skewed to the left or right.

The Empirical Rule can be used to predict the population from which the data were taken, making it a useful tool when examining data with a normal distribution.

The range stays 48°

Step-by-step explanation:

The range is the difference between the highest and lowest values in the data set. Before adding 80.2°, the highest temperature is 105° and the lowest temperature is 57°, so the range is 105° - 57° = 48°.

After adding 80.2°, the highest temperature becomes 105° + 80.2° = 185.2° and the lowest temperature becomes 57° + 80.2° = 137.2°. So the new range is 185.2° - 137.2° = 48°.

The estimate is,

f(117) = 56

Step-by-step explanation:

We use the linear approximation,

L(x) = f(a) + f'(a)(x-a)

In our case,

x = 117,

a = 115

f(115) = f(a) = 50,

f'(a) = f'(115) = 3

Putting all this into the linear approximation equation, we get,

L(117) = f(115) + (f'(115))(117-115)

L(117) = 50 + 3(2)

L(117) = 56
