Answers

Answer 1

The measure of the missing angle in a given pentagon is 115°. Therefore, option A is the correct answer.

What is the formula for interior angle of a regular polygon?

The formula for calculating the sum of interior angles is (n-2)×180° where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

2) The sum of the interior angles of a nonagon

Here, n=9

(9-2)×180°

= 1,260°

3) Here, ∠3+∠4=180°

∠3=101°

101°+∠4=180°

∠4=79°

So, option A is the correct answer.

4) Given that, a regular polygon with 12 sides.

Now, sum of the interior angles = (12-2)×180°

= 1800°

Measure of each angle = 1800/12

= 150°

5) Four of the angles of a pentagon measure 85°, 110°, 135°, and 95°.

Let the measure of fifth angle be x°

85°+110°+135°+95°+x°=540°

425°+x°=540°

x°=115°

So, option A is the correct answer.

The measure of the missing angle in a given pentagon is 115°. Therefore, option A is the correct answer.

The dimensions of the rectangle are: length= 18 in and width =1 in.

Quadrilaterals

There are different types of quadrilaterals, for example, square, rectangle, rhombus, trapezoid, and parallelogram.  Each type is defined accordingly to its length of sides and angles. For example, in a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

The area of a rectangle can be found for the formula : l*w, where b = length and w =width. The question gives that the area is 18 in².

For this question, the length exceeds its width by 17 inches - l=w+17. Thus,  from the value of area given, you can find the values of the length and width of the rectangle.

A=l*w

18=(w+17)*w

18=w²+17w

w²+17w-18=0

Next step will be solve the previous equation ( W²+17W-18=0)

[tex]w_{1,\:2}=\frac{-17\pm \sqrt{17^2-4\cdot \:1\cdot \left(-18\right)}}{2\cdot \:1}\\ \\ w_{1,\:2}=\frac{-17\pm \:19}{2\cdot \:1}[/tex]

Therefore,

[tex]w_1=\frac{-17+19}{2\cdot \:1}=1\\ \\ \\ w_2=\frac{-17-19}{2\cdot \:1}=-18[/tex]

For dimensions, only positive numbers must be used. Then, the width is equal to 1 inch.

As, the area (l*w) is 18 in², you have.

18=l*w

18=l*1

l=18 in

Chocolate costing $\$10$ per pound is mixed with nuts costing $\$4$ per pound to make a mixture costing $\$6$ per pound. What fraction of the mixture's weight is chocolate

Answers

1/3 portion of the mixture, costing $\$6$ contains chocolate.

Calculation of the weight of the chocolate in the mixture:

Assume that, in a mixture:

chocolate = x pound

nuts = y pound

mixture= x+y

The desired value is found by dividing the weight of the chocolate by the overall weight, or x/(x+y).

From the given data,

cost of x pound chocolate at $\$10$per pound = 10x

cost of y pound nuts at $\$4$ per pound = 4y

cost of x+y pound mixture at $\$6$ = 6(x+y)

As per condition,

10x + 4y = 6(x+y)

⇒10x + 4y = 6x+ 6y

⇒4x = 2y

⇒y = 2x

The fraction of the chocolate in the mixture is

[tex]x/(x+y)[/tex] = [tex]x/(x+2x)[/tex] = [tex]x/3x[/tex] = 1/3

Therefore, chocolate makes  1/3 of the mixture's weight.

In a proportionate stratified sample of 120, there are 72 Whites, 24 Latinos, 18 Blacks and 6  others.

Proportionate Stratified Sample

A proportionate stratified sample is one in which the size of the strata in the sample is proportional to the size of the strata in the population; in other words, the chance of selecting a unit from a stratum depends on the relative size of that stratum in the population.

Calculating the Proportionate Stratified Sample

The given percentage of -

Whites = 60%

Latinos = 20%

Blacks = 5%

Strength of the sample = 120

⇒ Number of Whites = 60% of 120

The probability that a football game will go into overtime is 18%. What is the probability that two of three football games will go to into overtime

Answers

The probability that two of three football games will go to into overtime is 0.08

How to determine the probability that two of three football games will go to into overtime?

From the question, we have the following parameters about the probability

Sample size, n = 3

Proportion that goes to overtime, p = 18%

Number that goes into overtime, x = 2

The probability that two of three football games will go to into overtime is calculated using the following binomial probability

P(x) = nCx * p^x * (1 - p)^(n -x)

Substitute the known values in the above equation

P(2) = 3C2 * (18%)^2 * (1 - 18%)^(3 -2)

Express 18% as decimal

P(2) = 3C2 * (0.18)^2 * (1 - 0.18)^(3 -2)

Evaluate the difference

P(2) = 3C2 * (0.18)^2 * (0.82)^1

Evaluate the combination expression

P(2) = 3 * (0.18)^2 * (0.82)^1

Evaluate the exponent

P(2) = 3 * 0.0324 * (0.82)

Evaluate the product

P(2) = 0.079704

Approximate

P(2) = 0.08

Hence, the probability that two of three football games will go to into overtime is 0.08

Answers

Using the normal distribution, there is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For this problem, these parameters are given as follows:

[tex]\mu = 180, \sigma = 20, n = 40, s = \frac{20}{\sqrt{40}} = 3.1623[/tex]

A sum of 7100 is equivalent to a sample mean of 7100/40 = 177.5, which means that the probability is the p-value of Z when X = 177.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{177.5 - 180}{3.1623}[/tex]

Z = -0.79

Z = -0.79 has a p-value of 0.2148.

There is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.

The relationship that represents the law of cosines if the measure of the included angle between the sides a and b is D. area of square c² = area of square a² area of squareb² area of defect1 area of defect2

What is the law of cosine?

It should be noted that the cosine law is simply used to solving triangles.

The law simply states that c² = a² + b² - 2abcosC.

The correct option that illustrates this is D.

A rectangular parking lot is 253.5 feet long and 176.5 feet wide. a 55-gallon drum of asphalt sealer covers
4,000 square feet and costs $99.50. find the cost to seal the parking lot. (sealer can only be purchased in full
drums.)

Answers

Answer:

$1,194

Step-by-step explanation:

The area of the parking lot is 253.5(176.5) which equals 44,472.75. You then divide 44,472.75 by 4000 to see how many gallons you need to cover the parking lot. The answer to that was about 11.2 and since you can only purchase full drums you have to round it up to 12 to have enough. Finally, you multiply 12 by 99.50 and get your answer.

Do 7 ft, 9 ft, 11 ft form a right triangle

Answers

Answer:

no

Step-by-step explanation:

using the converse of Pythagoras' identity

if the square on the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

longest side = 11 and 11² = 121

7² + 9² = 49 + 81 = 130

since 121 ≠ 130 then sides do not form a right triangle

Pony and HAL are both releasing new gaming consoles at the same time. Assume that consumers value both equally. Each company is deciding what to charge. If they both charge $600, then they will split the market and each earn $500 million. If one firm charges less, then it will capture the market and earn a significantly higher profit, while the other firm will be driven out of the market and earn nothing. If they both charge a low price, each company will earn a small profit.--What are the dominant strategies for the two firms?Both firms should charge the higher price.HAL should charge $600 and Pony should charge less.Pony should charge $600 and HAL should charge less.Both firms should charge the lower price.Neither firm has a dominant strategy.b. Pony discovers that both firms buy components for the consoles from the same supplier. This supplier sells many parts to Pony. To HAL, it sells just one critical component, but it is the only supplier because it owns the patent on it. Pony approaches HAL and offers to charge the high price if HAL will as well. But if HAL breaks the agreement, Pony will tell its supplier that it will pay more for its parts if the supplier completely stops selling to HAL. HAL knows from its market research that there is a price Pony could pay that would make it worthwhile to the supplier and that this would drive HAL out of the market. Pony would capture the market but make a significantly smaller profit.Assume there is no government regulation preventing this behaviour.--Pony's offer is an example ofan empty, or noncredible, threat.odd pricing.a credible threat, or promise.price discrimination.

It thus has equal power densities in the TM and TE polarizations (and the two corresponding electric field components are also 90 out of phase from each other, though this is not important for the present problem). The signal is incident at an angle of 45 on ocean water, which is nonmagnetic, with a relative permittivity of & = 81 and a conductivity of o=4 [S/m]. What percentage of the power that is reflected from the surface of the ocean? Do you think the reflected wave will be circularly polarized? You do not have to do any calculations, but justify your answer. (You may assume that the incident power density of the RHCP wave is 1 [W/m] if you wish, but the final answer will not depend on the power density of the incident wave.)
