Two sides of a triangle measure 8 cm and 15 cm. Whi[:h could be the length of the third side?
O 6 cm
O 18 cm
O 24 cm
O 28 cm

Answers

18 cm is correct .

Step-by-step explanation:

The sum of two smaller sides is greater that the largest side.

It is given that the two sides of a triangle measure 8 cm and 15 cm.

Case 1: Let 8 cm and 15 cm. are smaller side. So,

Third side < 8 + 15

Third side < 23

It means 3rd side must be less than 23

Case 2: Let 15 cm is the largest side.

15 < Third side + 8

15 - 8 < Third side

7 < Third side

It means 3rd side must be greater than 7.

Since only 18 is less than 23 and greater than 7, therefore the possible length of third sides is 18 cm and option 2 is correct.

4. Repeat exercise 3 using the Secant method. Repeat iterations until the approximate error becomes less than 0.1%. (20%] a. Which method is better? Secant or False-position?

Answers

The correct answer is The logic behind the Secant method is to iteratively update two initial guesses, x0 and x1, based on the function evaluations at those points. The formula x2 = x1 - (f(x1) * (x1 - x0)) / (f(x1) - f(x0)) is used to update the guesses and obtain a new approximation, x2

Here's an example MATLAB code that implements the Secant method to find the root of a function:

% Function to find the root of

function y = myFunction(x)

[tex]y = x^3 - 5*x^2 + 6*x - 2;[/tex]

end

% Secant method

x0 = 0; % Initial guess x0

x1 = 1; % Initial guess x1

approx_error = 1; % Initial approximation error

while approx_error > 0.001 % Set the desired approximation error threshold

[tex]x2 = x1 - (myFunction(x1) * (x1 - x0)) / (myFunction(x1) - myFunction(x0));[/tex]

[tex]approx_error = abs((x2 - x1) / x2) * 100; % Calculate the approximation[/tex]error

   x0 = x1;

   x1 = x2;

The logic behind the Secant method is to iteratively update two initial guesses, x0 and x1, based on the function evaluations at those points. The formula x2 = x1 - (f(x1) * (x1 - x0)) / (f(x1) - f(x0)) is used to update the guesses and obtain a new approximation, x2. The iteration continues until the approximation error, calculated as the absolute difference between x2 and x1 divided by x2, falls below the desired threshold (in this case, 0.001).

To compare the Secant method with the False-position method, you can apply both methods to the same function and compare their convergence and accuracy. You can also analyze the number of iterations required for each method to achieve a certain level of approximation error.

Please note that in order to generate graphs and screenshots with results, it would be best to run the code in a MATLAB environment and visualize the results directly.

Using the part-whole meaning of a fraction, find the larger of each. Write down your explanation. 12 10 d. and and f. and 101 19

Answers

we can conclude that 12/17 is the larger fraction between 12/17 and 12/19 using the part-whole meaning of a fraction.

To determine which fraction is larger between 12/17 and 12/19 using the part-whole meaning of a fraction, we need to compare the sizes of the parts (numerators) relative to the wholes (denominators) for both fractions.

Let's consider the fractions 12/17 and 12/19:

For 12/17:

- The numerator, 12, represents a part of the whole.

- The denominator, 17, represents the total number of equal parts into which the whole is divided.

For 12/19:

- The numerator, 12, also represents a part of the whole.

- The denominator, 19, represents the total number of equal parts into which the whole is divided.

Since the numerators are the same (both 12) and we are comparing the fractions with the same numerator, the fraction with the smaller denominator represents larger parts or more significant portions of the whole.

Comparing the denominators, we can see that 17 is smaller than 19. This means that the whole in 12/19 is divided into fewer parts compared to the whole in 12/17. Therefore, each part of the whole in 12/17 is larger than each part in 12/19.

As a result, we can conclude that 12/17 is the larger fraction between 12/17 and 12/19 using the part-whole meaning of a fraction.

5. Let f be a continuous function on R. Suppose f(x) > 0 for all x and (f(x))2 = 2 5c" f for all x > 0. Show that f(x) = x for all x > 0. . -

Answers

Given that f is a continuous function on R, f(x) > 0 for all x, and [tex]f(x)^{2}[/tex] = 2f for all x ≥ 0, we need to show that f(x) = x for all x ≥ 0.

Let's assume that there exists a value a ≥ 0 for which f(a) ≠ a. Since f(x) is continuous, the Intermediate Value Theorem can be applied. Consider the function g(x) = f(x) - x. Since g(a) ≠ 0, either g(a) > 0 or g(a) < 0.

If g(a) > 0, it implies that f(a) - a > 0, which leads to f(a) > a. But this contradicts the given condition that f(x) > 0 for all x. Hence, g(a) cannot be greater than 0.

Similarly, if g(a) < 0, it implies that f(a) - a < 0, which leads to f(a) < a. Again, this contradicts the given condition that f(x) > 0 for all x. Therefore, g(a) cannot be less than 0.

Since g(a) cannot be greater than 0 or less than 0, the only possibility is that g(a) = 0, which implies f(a) = a. This holds true for all a ≥ 0. Hence, we can conclude that f(x) = x for all x ≥ 0.

Therefore, based on the given conditions, we have shown that f(x) = x for all x ≥ 0.

These values are ____ times the mean median, and mode of the monthly salaries.

Answers

Answer:

30

Step-by-step explanation:

The mean, median, and mode of the given monthly salary is 1794, 1790, and 1940, respectively.

What is the measure of central tendency?

Measures of central tendency assist in the discovery of a data set's middle, or average. The mode, median, and mean are the three most popular metrics of central tendency.

Mode: It is the most common value in a given data set.

Median: In an ordered data set, the median is the number in the middle.

Mean: It is the total number of values divided by the sum of all values.


For the given data, the mean, median and the mode of the data can be found as shown below,

Sum of the Observations

= 1940 + 1660 + 1860 + 2100 + 1720 + 1540 + 1760 + 1940 + 1820 + 1600

= 17940

Number of Observations = 10

The mean of the data is,

Mean = Sum of Observations / Number of Observations

          = 17940 / 10  
          = 1794

The median of the data can be found by arranging the data in an order first. Therefore, the data can be arranged as,

1540160016601720176018201860194019402100

The median of the data is,

Median = (Sum of the two mid values) / 2

             = (1760 + 1820) / 2

             = 1790

The mode of the data is 1940, since this is repeated twice.

b.

If the salary of each employee is increased by 5% that means that the value of each observation in the data will increase by 5%. Therefore, The raise increases the mean, median, and mode by 5% each.

c.

As it is now required to find the mean, median, and mode of the annual salary; there is a need to multiply the monthly salary of each employee by 12. Therefore, the value of each observation will be 12 times its original value. These values are 12 times the mean median, and mode of the monthly salaries.

Answers

The equation that represents the sentence "0.7 increased by a number is 3.8" is d) 0.7 + n = 3.8

To understand why this equation is the correct representation, let's break it down. The phrase "a number" can be represented by the variable n, which stands for an unknown value. The phrase "0.7 increased by" implies addition, and the number 0.7 is being added to the variable n. The result of this addition should be equal to 3.8, as stated in the sentence.

Therefore, we have the equation 0.7 + n = 3.8, which indicates that when we add 0.7 to the unknown number represented by n, we obtain a value of 3.8. This equation accurately captures the relationship described in the sentence, making option d, 0.7 + n = 3.8, the correct choice.

•= •and a math drawing, explain why multiplying the numerator and
denominator of a fraction by the same number results in the same number (equivalent fraction).
In your explanation, discuss the following:
• what happens to the number of parts and the size of the parts;
• how your math drawing shows that the numerator and denominator are each multiplied by 4;
• how your math drawing shows why those two fractions are equal.

Answers

When you multiply the numerator and denominator of a fraction by the same number, you are effectively scaling up or scaling down the fraction without changing its value. The math drawing demonstrates how the number of parts and the size of the parts change, while still representing the same amount, thus showing why the two fractions are equal.

To explain why multiplying the numerator and denominator of a fraction by the same number results in an equivalent fraction, let's use the example you provided: 2/4.

First, let's understand the concept of a fraction. A fraction represents a part of a whole. The numerator represents the number of parts we have, and the denominator represents the total number of equal parts that make up the whole.

In the given example, 2/4, the numerator is 2, indicating that we have 2 parts out of a total of 4 equal parts. The denominator tells us that the whole is divided into 4 equal parts.

Now, let's say we want to multiply both the numerator and denominator by the same number, let's say 4. The new fraction becomes (2 * 4) / (4 * 4), which simplifies to 8/16.

Let's visualize this using a math drawing. Consider a rectangular shape representing the whole, divided into 16 equal parts, like a grid of squares, with 8 of those squares shaded. This represents the fraction 8/16.

Now, let's compare this to the original fraction, 2/4. If we draw a rectangle divided into 4 equal parts, and shade 2 of those parts, we can see that it represents the same amount as the fraction 8/16. By multiplying both the numerator and denominator by 4, we have essentially scaled up the size of each part and increased the number of parts.

Visually, the original fraction of 2/4 had fewer total parts (4) but larger-sized parts, while the equivalent fraction of 8/16 had more total parts (16) but smaller-sized parts. However, the total shaded area in both cases remains the same, which indicates that the fractions are equal.

Therefore, the margin of error of a 98% confidence interval estimate of the percentage of the population that favor free tuition is 4.2%.

The margin of error is the difference between the sample statistic and the population parameter. It shows how much the sample result can deviate from the actual population parameter.Here, the sample size n = 750, and the proportion of adults in the US who favor free tuition for four-year colleges is p = 330/750 = 0.44.Using the z-distribution, we can calculate the margin of error for the 98% confidence interval as follows:zα/2 = z0.01/2 = 2.33margin of error = zα/2 * √(p(1-p)/n)margin of error = 2.33 * √(0.44(1-0.44)/750)margin of error ≈ 0.042 or 4.2%Therefore, the margin of error of a 98% confidence interval estimate of the percentage of the population that favor free tuition is 4.2%.

Answers

The binary expansion 1100101 base 2 can be converted to base 4 and base 10. In base 4, the expansion is 313 and in base 10, it is 101.

To convert the binary expansion 1100101 base 2 to base 4, we group the binary digits into pairs from right to left. Starting from the rightmost pair, we convert each pair to its equivalent base 4 digit. In this case, the pairs are 01, 01, 10, and 11, which correspond to the base 4 digits 1, 1, 3, and 3, respectively. So the base 4 expansion is 313.

To convert the binary expansion 1100101 base 2 to base 10, we can use the positional value system. Each binary digit represents a power of 2. Starting from the rightmost digit, we assign powers of 2 to each digit in increasing order from right to left. In this case, the digits are 1, 0, 1, 0, 0, 1, and 1, which correspond to the powers of 2^6, 2^5, 2^4, 2^3, 2^2, 2^1, and 2^0, respectively. Evaluating these powers of 2, we get 64, 0, 16, 0, 0, 2, and 1. we obtain 64 + 0 + 16 + 0 + 0 + 2 + 1 = 101 in base 10.

Therefore, the binary expansion 1100101 base 2 is equivalent to 313 base 4 and 101 base 10.
