The sum of the interior angles of a regular polygon is 1080°.

a. ) Classify the polygon by the number of sides.


b. ) What is the measure of one interior angle of the

polygon?


c. ) What is the measure of one exterior angle of the

polygon?

Answers

Answer 1

a) The polygon has 8 sides and is called an octagon.

b) The measure of each interior angle of the octagon measures 135 degrees.

c) The measure of each exterior angle of the octagon measures 45 degrees.

a. To classify the polygon by the number of sides, we can use the formula for the sum of the interior angles of a polygon:

Sum of interior angles = (n - 2) x 180 degrees

where n is the number of sides of the polygon.

In this case, we are given that the sum of the interior angles is 1080 degrees. So we can set up an equation as follows:

(n - 2) x 180 = 1080

Simplifying this equation, we get:

n - 2 = 6

n = 8

b. To find the measure of one interior angle of the polygon, we can use the formula for the measure of each interior angle of a regular polygon:

Measure of each interior angle = (n - 2) * 180 degrees / n

Substituting n = 8 into this formula, we get:

Measure of each interior angle = (8 - 2) * 180 degrees / 8

= 135 degrees

c. To find the measure of one exterior angle of the polygon, we can use the fact that the sum of the interior and exterior angles of a polygon is 180 degrees. Therefore, the measure of each exterior angle of a regular polygon is:

Measure of each exterior angle = 360 degrees / n

Substituting n = 8 into this formula, we get:

Measure of each exterior angle = 360 degrees / 8

= 45 degrees

Jessie likes to ride her bike around a circular track with a radius of
25.8 yards. If she rides around the track 3 times, about how far
will she ride?
A 162 yards
B 243 yards
C 309 yards
D 486 yards

Answers

Jessie will cover a distance of about 486 yards.

What is the distance covered by Jessie?

The distance that Jessie will ride around the circular track can be calculated as the circumference of the circle.

The formula for the circumference of a circle is:

C = 2πr

Where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

In this case, the radius of the circle is 25.8 yards.

We can substitute that into the formula and simplify:

C = 2πr

C = 2 × 3.14 × (25.8)

C = 162.024 yds

Since the circumference of the circular track is approximately 162.024 yards.

If Jessie rides around the track 3 times, the total distance she will ride is:

3 × 162.024 = 486 yards.

Therefore, option D) 486 yards is the correct answer.

Find the annual percentage yield (APY) for the investment. $8000 at 4.75% compounded daily The annual percentage yield (APY) is%. (Type an integer or decimal rounded to three decimal places as needed.)​

Answers

Answer:

The annual percentage yield (APY) is a measure of the return on an investment that takes into account the effect of compounding interest. To calculate the APY for an investment of $8000 at an interest rate of 4.75% compounded daily, you can use the formula:

APY = (1 + r/n)^(n*t) - 1

where r is the annual interest rate as a decimal (0.0475 in this case), n is the number of times the interest is compounded per year (365 for daily compounding), and t is the number of years (1 in this case).

Plugging these values into the formula gives:

APY = (1 + 0.0475/365)^(365*1) - 1 APY ≈ 0.0486

So, the APY for this investment is approximately 4.86%.

Group of answer choices $2377.32 $2620.36 $2628.11 $2510.43

Answers

Answer:

The formula for calculating the future value of an investment with compound interest is:

A = P(1 + r/n)^(nt)

where A is the future value, P is the principal (initial amount), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time period in years.

In this case, P = $2500, r = 0.0125 (1.25% as a decimal), n = 12 (since the interest is compounded monthly), and t = 4.

Plugging these values into the formula, we get:

A = 2500(1 + 0.0125/12)^(12*4) ≈ $2,628.11

Therefore, the answer is $2628.11.

Answer: $ 2628.11

Step-by-step explanation:

Compound interest is nasty.

the formula (which you need to memorize) is:

[tex]A = P(1+\frac{r}{n} )^t^n[/tex]

A is the final amount, P is the principle, (original amount of money invested), r is the rate of return (as a decimal NOT percent), n is the number of times compounded annually, and t is the time, (in years), invested.

With all this information, our formula becomes:

[tex]A = 2500(1+\frac{0.0125}{12} )^4^8[/tex]

solving, we get A ≅ 2628.11

A horizontal line starting at 0, with tick marks every one-half unit up to 32. The line is labeled Wait Time In Minutes. The box extends from 9.5 to 24 on the number line. A line in the box is at 15.5. The lines outside the box end at 2 and 30. The graph is titled Burger Quick.

Which drive-thru typically has more wait time, and why?

Burger Quick, because it has a larger median

Super Fast Food, because it has a larger median
Super Fast Food, because it has a larger mean

Answers

We may infer from the box plots that Super Fast Food, with its smaller IQR, is better equipped to predict wait times than Burger Quick.answer is option (a).

What is median?

When values are sorted in order of magnitude, the median, a measure of central tendency, is the middle value in the collection.

BX charts are a common approach to visually depict a distribution of data, such as wait times at a drive-through restaurant. The bx in a bx plot depicts the interquartile range (IQR), or the middle 50% of the data, with the bttm and tp of the bx standing in for the first quartile (25th percentile) and third quartile (75th percentile), respectively. A line inside the box represents the median, or the value that splits the data into equal halves.

Although the range, which is the difference between the data's highest and minimum values, can also be used as a consistency indicator, its accuracy is lower than that of the IQR due to its sensitivity to extreme values and outliers. In this instance, Burger Quick's range is 30 - 2 = 28 minutes, while Super Fast Food's range is 27 - 3 = 24 minutes. Despite the fact that the range for Super Fast Food is narrower, it is still unreliable as a measure of consistency since it is significantly impacted by the outlier at 27 minutes, which is considerably outside the range of the data.

We may therefore deduce from the box plots that Super Fast Food, due to its smaller IQR, is able to estimate their wait time more reliably than Burger Quick.

What is the law of large numbers?
If you were using the relative frequency of an event to estimate the probability of the event, would it be better to use 100 trials or 500 trials? Explain.

Answers

The Law of Large Numbers is a fundamental concept in probability theory and statistics stating the number of trials of a random event increases, the average of the outcomes approaches the expected value of the event. It's better to use 500 trials.

In other words, as we repeat an experiment a large number of times, the proportion of times that a certain outcome occurs will converge to its probability of occurrence. This is an important concept in statistical inference, as it helps to ensure that the results of a sample are representative of the population from which it was drawn.

Now, if you were using the relative frequency of an event to estimate the probability of the event, it would be better to use 500 trials rather than 100 trials. The reason is that the larger the number of trials, the more accurate the estimate of the probability is likely to be.

Using a larger sample size reduces the impact of random variation and provides a more precise estimate of the true probability. The Law of Large Numbers tells us that as the sample size increases, the relative frequency of the event should converge to the true probability, so a larger sample size will generally give a more reliable estimate

From distance formula, the distance covered by a particle with position (x, y) as time, t is equals to the [tex] 18\sqrt{2}[/tex].

The distance d, traveled by the particle with position vector, r(t) = <x(t), y(t) > over the interval [a,b] is calculated by following

[tex]d = \int_{a}^{b} ( (\frac{dx}{dt})² +(\frac{dy}{dt})² )dt[/tex]. We have a particle with position value (x, y) as t varies in the time interval. The parametric equations are, x = 3 sin² (t), y = 3 cos²(t), on the

. A thermometer shows a temperature of -4.5°C. A nearby thermometer shows a temperature of 3.5°C. Explain how absolute value can be used to decide which temperature is warmer.​

Answers

Answer:

Step-by-step explanation:

The concept of absolute value can be used to determine which temperature is warmer between -4.5°C and 3.5°C. Absolute value is a mathematical function that returns the magnitude, or distance, of a number from zero, regardless of whether the number is positive or negative. In other words, the absolute value of a number is always a positive number.

In this case, we can calculate the absolute value of each temperature as follows:

| -4.5°C | = 4.5°C

| 3.5°C | = 3.5°C

The absolute value of -4.5°C is 4.5°C, which is greater than the absolute value of 3.5°C, which is 3.5°C. This means that -4.5°C is further from zero than 3.5°C, and therefore it is a colder temperature. So, the temperature of 3.5°C is warmer than the temperature of -4.5°C.

Therefore, we can use the concept of absolute value to determine which temperature is warmer by comparing the absolute values of the temperatures. The temperature with the greater absolute value is farther from zero, and therefore colder, while the temperature with the smaller absolute value is closer to zero, and therefore warmer.

What are equivalent fractions

Equivalent fractions are fractions that have different numerators and denominators, but represent the same amount or quantity. In other words, equivalent fractions are different ways of representing the same fraction.

-10/-7 = 10/7 {not equivalent to - 10/7}

-3 1/7 = -22/7 {not equivalent to - 10/7}

1 3/7 = 10/7 {not equivalent to - 10/7}

- -10/-7 = - (-10/-7) = - 10/7 {equivalent}

- 1 3/7 = - 10/7 {equivalent}

Therefore, the values that are equivalent to the fraction -10/7 are -(-10/7) and -13/7.

What is the right triangle?

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangle triangle, is a triangle in which one angle is a right angle, i.e., in which two sides are perpendicular. The relation between the sides and other angles of the right triangle is the basis for trigonometry.

What is the Pythagoras theorem?

In mathematics, the Pythagoras  theorem or  Pythagorean  theorem is a fundamental relation  in Euclidean geometry between the three sides  of a right triangle. It states that the area of the  square whose side is the hypotenuse is equal to  the sum of the areas of the squares on the other two sides.

Determined the area of a pentagon with a apothem of 10

Answers

The area of the pentagon with an apothem of 10 units is approximately 353.55 square units.

How to solve for the Apothem

Area = (Perimeter × Apothem) / 2

Central angle = 360° / 5 = 72°

To find the area of a regular pentagon with an apothem of 10 units, we can use the formula:

Area = (Perimeter × Apothem) / 2

Central angle = 360° / 5 = 72°

Now, consider the right triangle formed by half of a side, the apothem, and the radius. The angle between the apothem and the radius (half of the central angle) is:

Angle = 72° / 2 = 36°

In the right triangle, we have:

tan(36°) = (s/2) / 10

Solving for s:

s = 2 * 10 * tan(36°) ≈ 14.142 units (rounded)

Now that we have the length of one side, we can calculate the perimeter of the pentagon:

Perimeter = 5 * s ≈ 5 * 14.142 ≈ 70.710 units (rounded)

Finally, we can find the area of the pentagon using the formula:

Area = (Perimeter × Apothem) / 2

Area = (70.710 × 10) / 2

≈ 353.55 square units (rounded)

The area of the pentagon with an apothem of 10 units is approximately 353.55 square units.

rational root theorem

Answers

The possible rational zeros of the polynomial function are

±1, ±3, ±9, ±1/2, ±3/2, ±9/2

We have,

To find the possible rational zeros of the polynomial function P(x), we can use the Rational Root Theorem.

According to the theorem,

Any rational zero of a polynomial function with integer coefficients must have the form p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

In this case,

The constant term is -9, which has factors of ±1, ±3, ±9.

The leading coefficient is 2, which has factors of ±1, ±2.

So the possible rational zeros are:

±1/1, ±3/1, ±9/1, ±1/2, ±3/2, ±9/2

Simplifying the fractions, the possible rational zeros are:

±1, ±3, ±9, ±1/2, ±3/2, ±9/2

Thus,

The possible rational zeros are ±1, ±3, ±9, ±1/2, ±3/2, ±9/2

Answers

3⁴ is 3 times larger than 3³, 5³ is 5 times larger than 5², 7¹⁰ is 49 times larger than 7⁸ and 17⁶ is 289 times larger than 17⁴.

3⁴ / 3³ = (3 × 3 × 3 × 3) / (3 × 3 × 3) = 3

This means that 3⁴ is 3 times larger than 3³.

5³ is 5 times larger than 5².

5³ / 5² = (5 × 5 × 5) / (5× 5) = 5

7¹⁰ is 49 times larger than 7⁸.

7¹⁰/ 7⁸ = 7² =49

17⁶ is 289 times larger than 17⁴.

17⁶ /17⁴ = 289

Hence, 3⁴ is 3 times larger than 3³, 5³ is 5 times larger than 5², 7¹⁰ is 49 times larger than 7⁸ and 17⁶ is 289 times larger than 17⁴.

08.02 MC) The two plots below show the heights of some sixth graders and some seventh graders of a school: Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there are 2 dots above the second mark, 3 dots above the third mark, 1 dot above the fifth mark. The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.7. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.) (1 point) 0.5 1.2 1.7 3.4

Answers

The variability in the heights of the seventh graders is approximately 0.6 times the variability in the heights of the sixth graders.

What is mean absolute deviation?

The variability or dispersion of a set of data is measured by the mean absolute deviation (MAD). By averaging the absolute differences between each data point and the set mean, it is calculated. Because it is less impacted by high values or outliers, the MAD is a more reliable measure of variability than the standard deviation. The MAD is always a non-negative number and is stated in the same units as the data. Greater variability is indicated by a bigger MAD, whereas a smaller MAD suggests that the data points are more variable and are consequently closer to the mean. The MAD is frequently used to track process variation in descriptive statistics and quality control applications.

Given that, MAD for the sixth graders is 1.2 and the MAD for the seventh graders is 0.7.

To determine the relation of variability we take the ratio as:

0.7 / 1.2 ≈ 0.6

Hence, the variability in the heights of the seventh graders is approximately 0.6 times the variability in the heights of the sixth graders.
