Answer: No you can not make any triangles with 2 inches, 2 inches and 4 inches. hoped this helped!

Step-by-step explanation:

The price for the monthly fee will be;

⇒ x = $9.99  

And, The price per movie rental will be;

⇒ y = $2.99

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Yolanda is charged $21.95 for her monthly fee and 4 movie rentals.

And, Jeffrey is charged $30.92 for the same monthly fee and 7 movie rentals.

Now,

Let the price for the monthly fee = x

And, The price for the movie rental = y

Hence, We can formulate the expression for Yolanda;

⇒ x + 4y = $21.95

And,  We can formulate the expression for Jeffrey;

⇒ x + 7y = $30.92

Subtract equation (ii) from (i), we get;

⇒ 7y - 4y = $30.92 - $21.95

⇒ 3y = $8.97

⇒ y = $2.99

And, x + 4y = $21.95

x + 4 × 2.99 = 21.95

x + $11.96 = $21.95

x = $21.95 - $11.96

x = $9.99

Thus, The price for the monthly fee = $9.99  

And, The price per movie rental = $2.99

A 90% confidence interval for the population mean μ is approximately (13.8, 16.8), rounded to one decimal place as needed.

To construct a 90% confidence interval for the population mean μ, we will use the following formula:

CI = x ± z*(σ/√n)

where:

First, we need to find the z-score corresponding to a 90% confidence level.

Since a 90% confidence interval leaves 10% in the tails (5% in each tail), we will look up the z-score that corresponds to an area of 0.95 (0.50 + 0.45) in a standard normal distribution table or use a calculator to find the inverse of the standard normal distribution.

The z-score for a 90% confidence interval is approximately 1.645.

Now, we can plug the values into the formula:

CI = 15.3 ± 1.645*(8/√75)

Now, multiply the z-score by the standard error:

CI = 15.3 ± (1.645 * 0.924)

CI = 15.3 ± 1.52

Finally, calculate the confidence interval:

So, a 90% confidence interval for the population mean μ is approximately (13.8, 16.8), rounded to one decimal place as needed.

The given set of functions {f_1(x) = x, f_2(x) = x^2, f_3(x) = 3x - 6x^2} is linearly independent on the interval (-infinity, infinity).

Linear independence of a set of functions means that no function in the set can be expressed as a linear combination of the other functions. In other words, for the set to be linearly independent, the only solution to the equation c_1f_1(x) + c_2f_2(x) + c_3f_3(x) = 0 should be c_1 = c_2 = c_3 = 0, where c_1, c_2, and c_3 are constants.

To determine if the given set is linearly independent, we need to check if there exist non-zero constants c_1, c_2, and c_3 such that c_1f_1(x) + c_2f_2(x) + c_3f_3(x) = 0 for all x in the interval (-infinity, infinity).

By substituting the functions into the equation and equating the coefficients of the terms with the same powers of x, we can solve for c_1, c_2, and c_3. If the only solution is c_1 = c_2 = c_3 = 0, then the set is linearly independent. In this case, the given set is indeed linearly independent as there is no non-zero solution to the equation, confirming that the functions are not dependent on each other.

The correct answer is all of the above options affect the company's financial statements in different ways, but the establishment of the allowance directly affects the reported net income.

For a company using the allowance method of accounting for uncollectible accounts, the establishment of the allowance, writing off of a specific account, and recovery of an account previously written off as uncollectible all affect its financial statements, but in different ways:

The establishment of the allowance: This directly affects the amount of bad debt expense recognized in the income statement, which in turn affects the reported net income. When the company establishes an allowance for uncollectible accounts, it recognizes an expense for the estimated amount of uncollectible accounts, which reduces the reported net income.

The writing off of a specific account: This does not affect the net income directly because the expense for bad debt has already been recognized when the allowance was established. However, it does affect the balance sheet because the amount of accounts receivable and the allowance for uncollectible accounts are both reduced.

The recovery of an account previously written off as uncollectible: This affects both the income statement and the balance sheet. The amount of the recovery is recognized as revenue, which increases the reported net income. Additionally, the accounts receivable and allowance for uncollectible accounts are both increased by the amount of the recovery.

Therefore, the correct answer is all of the above options affect the company's financial statements in different ways, but the establishment of the allowance directly affects the reported net income.

The utility functions in options a, b, c, and f are not risk-averse on the interval [a,b], while the utility functions in options d and e are risk-averse on the interval [a,b].

In economics and finance, risk aversion refers to a preference for less risky options over riskier ones. Utility functions are mathematical representations of an individual's preferences, and they help determine whether someone is risk-averse, risk-neutral, or risk-seeking. A risk-averse individual would have a concave utility function, indicating a decreasing marginal utility of wealth.

For options a, b, c, and f, the utility functions are and f(x) = -ln(x), g(x) = \(-e^(^-^x^)\), h(x) = \(-4x^2\) - 10x, respectively. These utility functions do not exhibit concavity, which means they are not risk-averse. Instead, they either show risk-seeking behavior (options a and b) or risk-neutrality (options c and f).

On the other hand, options d and e have utility functions f(x) = ln(x), g(x) = 1/(e^(2x)), h(x) = \(-x^2\) + 10,000x and f(x) = ln(-2x), g(x) = -1/(\(e^(^2^x^)\)), h(x) = \(x^2\) - 100,000x, respectively. These utility functions display concavity, indicating a decreasing marginal utility of wealth. Thus, options d and e can be considered risk-averse on the interval [a,b].

Step-by-step explanation:

The question is not complete let us assume a mean of 80 and a standard deviation of 10.

The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

\(z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean, \sigma=standard\ deviation\\\\for\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\\)

Given that μ = 80, σ = 10

For x = 60:

\(z=\frac{x-\mu}{\sigma} =\frac{60-80}{10}=-2\\ \\\\\\\)

For x = 100:

\(z=\frac{x-\mu}{\sigma}=\frac{100-80}{10}=2\\\\ \\\\\)

Therefore from the normal distribution table, P(60 < x < 100) = P(-2 < z < 2) = P(z < 2) - P(z < -2) = 0.9772 - 0.0228 = 0.9544

The point of diminishing returns is (20.98, 21247.3).

The point of diminishing returns occurs when the marginal cost of producing an extra unit of output exceeds the marginal revenue generated from selling that unit. Mathematically, it is the point at which the derivative of the production function equals zero and the second derivative is negative.

Given the polynomial function N(x) of degree 3, we can find the point of diminishing returns by finding the critical points where the first derivative equals zero and evaluating the second derivative at those points.

The derivative of N(x) is N'(x) = -18x² + 360x + 2250. To find the critical points, we set N'(x) = 0:

0 = -18x² + 360x + 2250

Dividing by -18 simplifies the equation:

0 = x² - 20x - 125

Using the quadratic formula, we find the solutions to the equation:

x₁,₂ = (20 ± √(20² - 4(1)(-125))) / 2(1)

x₁,₂ = 10 ± 5√5

Thus, the two critical points of N(x) are at x = 10 - 5√5 and x = 10 + 5√5.

To determine the point of diminishing returns, we evaluate the second derivative N''(x) = -36x + 360 at these critical points:

N''(10 - 5√5) = -36(10 - 5√5) + 360 ≈ -264.8

N''(10 + 5√5) = -36(10 + 5√5) + 360 ≈ 144.8

From the evaluations, we find that N''(10 + 5√5) is negative while N''(10 - 5√5) is positive. Therefore, the point of diminishing returns corresponds to x = 10 + 5√5.

To find the corresponding y-coordinate (N(10 + 5√5)), we can substitute the value of x into the original function N(x).

Hence, the point of diminishing returns is approximately (20.98, 21247.3).

Step-by-step explanation:

Based on the calculation, it appears that Matti had approximately 94 bottles of 0.5 litres and 11 bottles of 0.7 litres in the last patch of moonshine that he sold.

To solve the problem using the determinant method (Cramer's rule), we need to set up a system of equations based on the given information and then solve for the unknowns, which represent the number of 0.5 litre bottles and 0.7 litre bottles.

Let's denote the number of 0.5 litre bottles as x and the number of 0.7 litre bottles as y.

From the given information, we can set up the following equations:

Equation 1: 0.5x + 0.7y = 16.5 (total volume of moonshine)

Equation 2: 8x + 10y = 246 (total earnings from selling moonshine)

We now have a system of linear equations. To solve it using Cramer's rule, we'll find the determinants of various matrices.

Let's calculate the determinants:

D = determinant of the coefficient matrix

Dx = determinant of the matrix obtained by replacing the x column with the constants

Dy = determinant of the matrix obtained by replacing the y column with the constants

Using Cramer's rule, we can find the values of x and y:

x = Dx / D

y = Dy / D

Now, let's calculate the determinants:

D = (0.5)(10) - (0.7)(8) = -1.6

Dx = (16.5)(10) - (0.7)(246) = 150

Dy = (0.5)(246) - (16.5)(8) = -18

Finally, we can calculate the values of x and y:

x = Dx / D = 150 / (-1.6) = -93.75

y = Dy / D = -18 / (-1.6) = 11.25

However, it doesn't make sense to have negative quantities of bottles. So, we can round the values of x and y to the nearest whole number:

x ≈ -94 (rounded to -94)

y ≈ 11 (rounded to 11)

Therefore, based on the calculation, it appears that Matti had approximately 94 bottles of 0.5 litres and 11 bottles of 0.7 litres in the last patch of moonshine that he sold.

Analysis of variance (ANOVA) is a statistical tool used to test for equality of means across multiple groups or populations. This test helps to determine whether the observed differences between the means of different groups are statistically significant or simply due to chance.

ANOVA calculates the variation or deviation in the means of different groups by comparing the variance within the groups to the variance between the groups.

In ANOVA, the population is the entire group of individuals or objects that are being studied. For example, if we are comparing the means of three different age groups, the population would be all individuals in those three age groups.

ANOVA looks at the variance between these groups and within each group to determine if there is a statistically significant difference in means.

When conducting an ANOVA, standard deviations, variances, and means are all important measures of central tendency and variability. Standard deviations and variances are used to calculate the within-group variation and between-group variation.

Proportions, on the other hand, are not used in ANOVA as this test is specifically designed for continuous data, such as means.

Overall, ANOVA is a useful tool for analyzing differences in means across multiple populations.

By calculating the deviation or variation between and within groups, it can help researchers determine whether observed differences are statistically significant or not.

h(x) = -7/6x - 25/6.

Given h(-1)=-2 and h(-7)=-9

For linear function h(x), we can use slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.

To find m, we can use the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

h(-1) = -2 is a point on the line, so we can write it as (-1, -2).

h(-7) = -9 is another point on the line, so we can write it as (-7, -9).

Now we can find m using these points: m = (-9 - (-2)) / (-7 - (-1)) = (-9 + 2) / (-7 + 1) = -7/6

Now we can find b using one of the points and m. Let's use (-1, -2):

y = mx + b-2 = (-7/6)(-1) + b-2 = 7/6 + b

b = -25/6

Therefore, the linear function h(x) is:h(x) = -7/6x - 25/6

We can check our answer by plugging in the two given points:

h(-1) = (-7/6)(-1) - 25/6 = -2h(-7) = (-7/6)(-7) - 25/6 = -9

The answer is h(x) = -7/6x - 25/6.

\(h=10tan(60) = 17.321\)

with 3DP

The height of a right triangle with an angle that measures 60 degrees and a base of 10 adjacent to the 60 degree angle is 5√3.

A right triangle is a triangle in which one of the angles measures 90 degrees, and this angle is called the right angle.

Right triangles can be classified as acute or obtuse, depending on the measure of the other two angles. Acute triangles have two acute angles, whereas obtuse triangles have one obtuse angle. A 60-degree angle is an acute angle because it is less than 90 degrees.

The height of a right triangle is the length of a line perpendicular to the base that connects the base to the opposite vertex. The length of the height of a right triangle can be calculated using the trigonometric function sine. For the given triangle, the 60-degree angle is opposite the height, and the 10 is adjacent to it.

The trigonometric function we need to use in this case is sine. Therefore, the height h is given by:h = 10sin(60)h = 10(√3/2)h = 5√3
