Answer:
The correct options are;
1) The shape maps unto itself after a rotation of 270 degrees
2) The smallest angle of rotational symmetry is 90 degrees
3) The shape maps unto itself after a rotation of 180 degrees
Step-by-step explanation:
We note that the shape of a cross which consists of two equal members (segments) bisecting each other at right angles such that when a member is placed vertically upright, the other member will be horizontal, therefore we have;
After rotation by 90 degrees, the vertical member will become horizontal and vice versa
After rotation by 180 degrees, the vertical member will become horizontal and vice versa again
Similarly, after rotation by 270 degrees, the once vertical member will become horizontal and the horizontal member will become vertical

For each of the following statements, determine whether the statement is true or false (the latter including "not necessarily true"), and provide a brief explanation.
(a) A situation where everyone is playing a dominant strategy must be a Nash equilibrium.
(b) In a Nash equilibrium, everyone must be playing a dominant strategy.
(c) A two-person game in which each person has access to only two possible strategies will have at most one Nash equilibrium.
(d) In the following game, there exists only one pure-strategy equilibrium.
(e) In the following game of matching pennies, if player 2 plays (1/2∘H,1/2∘T) (i.e., plays both strategies with equal probability) then player 1 strictly prefers playing (1/2∘H,1/2∘ T ) to playing either H or T with probability 1.
(a) False. A situation where everyone is playing a dominant strategy does not necessarily guarantee a Nash equilibrium.
(b) False. In a Nash equilibrium, players may or may not be playing a dominant strategy.
(c) Not necessarily true. A two-person game with only two strategies for each player can have more than one Nash equilibrium.
(d) True. Without specific details about the game provided,
(e) False. In the game of matching pennies, if player 2 plays (1/2∘H,1/2∘T)
(a) False. A situation where everyone is playing a dominant strategy does not necessarily guarantee a Nash equilibrium. A Nash equilibrium occurs when no player can unilaterally change their strategy to improve their own payoff, regardless of what other players do. It is possible for a situation with dominant strategies for each player to result in a Nash equilibrium, but it is not a guarantee.
(b) False. In a Nash equilibrium, players may or may not be playing a dominant strategy. A Nash equilibrium simply represents a stable outcome where no player has an incentive to deviate from their chosen strategy given the strategies chosen by others. Players could be playing non-dominant strategies and still reach a Nash equilibrium.
(c) Not necessarily true. A two-person game with only two strategies for each player can have more than one Nash equilibrium. The number of Nash equilibria is not solely determined by the number of strategies available to each player but also depends on the payoffs and interactions between the strategies chosen by each player.
(d) True. Without specific details about the game provided, we cannot definitively determine if there exists only one pure-strategy equilibrium. However, if it is stated that there is only one pure-strategy equilibrium, then the statement would be true.
(e) False. In the game of matching pennies, if player 2 plays (1/2∘H,1/2∘T) with equal probability, player 1 does not strictly prefer playing (1/2∘H,1/2∘T) over playing either H or T with probability 1. Player 1's preferred strategy would depend on their own payoffs and the corresponding payoffs associated with the opponent's strategies. Without additional information about the payoffs in the game, we cannot make a definitive judgment on player 1's preferences.

Tony notes that an electronics store is offering a flat $20 off all prices in the store. Tony reasons that if he wants to buy something with a price of $50, then it is a good offer, but if he wants to buy something with a price of $500, then it is not a good offer. This is an example of: inconsistent reasoning; saving $20 is saving $20. the proper application of the Cost-Benefit Principle. inconsistent reasoning because prices are sunk costs. rational choice because saving 40% is better than saving 4%.
Answer: inconsistent reasoning; saving $20 is saving $20
Step-by-step explanation: Tony's reasoning would be deemed as being inconsistent because the discount offered on sale of items isn't based on proportion rather it is based on a specified amount. Tony is basing is judgement on percentage rather the specified discount amount on product. Hence, thinking the offer isn't good when buying more expensive product is erroneous as the offer isnt based on proportion and the same specified amount is saved across all items purchased.
Provide an appropriate response Suppose a uniform random ca be used to the outcome of an experiment with the outcomes ranging from 30 to 80?what is probability that this experiment results in an outcome less then 40?
The probability that the experiment results in an outcome less than 40 is 0.25.
To calculate the probability, we need to determine the range of outcomes that are less than 40 out of the total range of 30 to 80. The total range is 80 - 30 = 50. The range of outcomes less than 40 is 40 - 30 = 10.
To find the probability, we divide the range of outcomes less than 40 by the total range:
Probability = (Range of outcomes less than 40) / (Total range)
= 10 / 50
= 0.2
Therefore, the probability that the experiment results in an outcome less than 40 is 0.2 or **20%**.

what is PEMDAS? and how do you use it?
Answer:
please excuse my dear aunt sallyStep-by-step explanation:
PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction. For any expression, all exponents should be simplified first, followed by multiplication and division from left to right and, finally, addition and subtraction from left to right.
PEMDAS stands for Parentheses, Exponents, Multiply, Divide, Add, and Subtract.
How to use it?
Well, if you have a problem like:
19 + 4 x 3.
If someone didn't know the rule of PEMDAS, they would start from the beginning of the problem, but no.
If you follow the rule, MULTIPLYING comes before ADDING. So you need to solve whatever comes first in PEMDAS.
4 x 3 = 12, then plus 19 = 31

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?
Answer:
The total repair cost for each store is the cost of repairs added to the sales tax. The amount of money saved will be the difference between the two total costs.
Answer:
Gratuity of $180 I would multiply the actual repair cost without including tax to determine the gratuity. So just multiply $1200 by 0.15 getting $180. As an suggestion, calculating 15% in your head is actually quite simple. What you do is calculate 10%, divide that in half, then add together. So for the $1200 example, you have 1200/10 = 120 half of 120 is 60 120 + 60 = 180 So you have a top of $180.
Step-by-step explanation:
in one of the films (Year of the Elephant, Bab el-Oued City, and Long Journey Home) feature a representation of Islam either as character, plot, or theme. Discuss the way in which Islam is portrayed in two of the works, comparing and contrasting between the two works AND discussing how these representations help us understand the overall message of the two works
A. The film's overall message seems to emphasize the importance of personal growth, self-discovery, and finding one's own path amidst societal and religious expectations.
B. Both films offer nuanced perspectives on the role of Islam in society, encouraging viewers to critically examine the complexities and implications of religious beliefs and practices.
Among the three films mentioned, "Year of the Elephant" and "Bab el-Oued City" feature representations of Islam. Let's discuss how Islam is portrayed in these two works, compare and contrast their depictions, and analyze how these representations contribute to the overall messages of the films.
"Year of the Elephant": "Year of the Elephant" is a Moroccan film directed by Hamid Bennani. It is based on a novella by renowned Moroccan author Tahar Ben Jelloun. The story revolves around Zahra, a young woman struggling with her faith and personal identity. Islam is a central theme in the film, explored through Zahra's spiritual journey.
Islam is portrayed as a deeply ingrained cultural and religious force in Zahra's life. Zahra grapples with societal expectations and norms associated with being a Muslim woman. The film highlights traditional interpretations of Islam that restrict women's freedom and agency. There is a focus on the pressures faced by Zahra, including her arranged marriage and adherence to conservative gender roles prescribed by her community.
The portrayal of Islam in "Year of the Elephant" raises questions about the intersection of religion, culture, and personal autonomy. It examines the tension between adhering to religious traditions and pursuing individual desires. The film's overall message seems to emphasize the importance of personal growth, self-discovery, and finding one's own path amidst societal and religious expectations.
"Bab el-Oued City": "Bab el-Oued City" is an Algerian film directed by Merzak Allouache. The narrative revolves around societal tensions and political unrest in Algeria during the 1990s. While Islam is not the primary focus of the film, it is depicted as an influential aspect of Algerian society, particularly within the context of political and ideological struggles.
In "Bab el-Oued City," Islam is portrayed through various characters representing different perspectives and interpretations. Some characters are depicted as devout Muslims, engaging in rituals and prayers, while others exploit religion for personal gain or political manipulation. There is a portrayal of religious fundamentalism and its impact on society, highlighting the extremist views held by certain individuals.
The film explores the complex relationship between Islam, politics, and social dynamics. It sheds light on how religious ideologies can be manipulated to serve political agendas, leading to division and conflict within communities. The representation of Islam in "Bab el-Oued City" serves to provoke thought about the consequences of radicalization and the need for societal unity amidst ideological differences.
While both films touch upon the theme of Islam, their portrayals differ in focus and approach. "Year of the Elephant" primarily explores the personal struggles and identity crisis of an individual Muslim woman within a traditionalist society. On the other hand, "Bab el-Oued City" delves into the broader socio-political implications of Islam within a country undergoing significant turmoil.
In terms of their overall messages, "Year of the Elephant" emphasizes individual liberty and self-discovery within the confines of religious and societal expectations. It encourages viewers to question and challenge prevailing norms to find personal fulfillment. Conversely, "Bab el-Oued City" draws attention to the dangers of extremism and manipulation of religious beliefs for political purposes. It underscores the importance of understanding and bridging ideological divides to foster harmony and progress.
Both films offer nuanced perspectives on the role of Islam in society, encouraging viewers to critically examine the complexities and implications of religious beliefs and practices.

A company buys a new bulldozer for $134350. The company depreciates the bulldozer linearly over its useful life of 21 years. Its salvage value at the end of 21 years is $11500. Depreciation is the decrease or loss in value of the equipment due to age, wear, or market conditions. A) Express the value of the bulldozer, V, in terms of how many years old it is, t. V = _______B) The value of the bulldozer after 5 years is $
A)The expression for the value of the bulldozer in terms of how many years old it is, t, is: V = $134,350 - ($5,530.95 * t) B) The value of the bulldozer after 5 years is $106,695.25.
To express the value of the bulldozer, V, in terms of how many years old it is, t, we can use the concept of linear depreciation. Linear depreciation assumes that the value decreases at a constant rate over time. In this case, the initial value of the bulldozer is $134,350, and it depreciates over 21 years.
The depreciation per year can be calculated by subtracting the salvage value ($11,500) from the initial value and dividing it by the useful life of the bulldozer:
Depreciation per year = (Initial value - Salvage value) / Useful life
Depreciation per year = ($134,350 - $11,500) / 21
Now, we can express the value of the bulldozer, V, in terms of the number of years, t, using the depreciation per year:
V = Initial value - (Depreciation per year * t)
V = $134,350 - ([$134,350 - $11,500] / 21) * t
B) To find the value of the bulldozer after 5 years, we substitute t = 5 into the expression:
V = $134,350 - ($5,530.95 * 5)
V = $134,350 - $27,654.75
V = $106,695.25

Calculate the present value of a loan that could be cleared by payments of $3,400 at the end of every 6 months for 7 years if money earns 5.19% compounded semi-annually.
Round to the nearest cent
The present value of the loan, rounded to the nearest cent, is $37,196.88.
To calculate the present value of a loan, we can use the formula for the present value of an ordinary annuity:
PV = PMT * ((1 - (1 + r)^(-n)) / r),
where PV is the present value, PMT is the periodic payment, r is the interest rate per period, and n is the number of periods.
In this case, the periodic payment is $3,400, the interest rate is 5.19% compounded semi-annually, and the loan term is 7 years, which is equivalent to 14 semi-annual periods.
First, let's convert the interest rate to its semi-annual equivalent by dividing it by 2. So, the interest rate per semi-annual period is 5.19% / 2 = 2.595%.
Now, we can plug these values into the formula:
PV = $3,400 * ((1 - (1 + 0.02595)^(-14)) / 0.02595).
Calculating this equation, we find that the present value of the loan is approximately $37,196.88 when rounded to the nearest cent.
Therefore, the present value of the loan, rounded to the nearest cent, is $37,196.88.

For each of the following, determine whether the equation defines y as a function of x. 2 x + 3y = 4 Function O Not a function 4x + y = 0 Function Not a function 2 x + y = 16 Function O Not a function = √√x-1 O Not a function ? y= O Function X
To determine whether an equation defines y as a function of x, we need to check if, for each value of x, there is a unique corresponding value of y. If there is more than one value of y for a particular x, the equation does not define y as a function of x. Based on the given equations, 2x + 3y = 4 and 4x + y = 0 define y as a function of x, while 2x + y = 16 and √√(x-1) = 0 do not define y as a function of x.
The equation 2x + 3y = 4 can be rearranged to solve for y as follows: 3y = 4 - 2x, y = (4 - 2x)/3. For each value of x, there is a unique corresponding value of y, so this equation defines y as a function of x.
Similarly, the equation 4x + y = 0 can be rearranged to solve for y: y = -4x. Again, for each value of x, there is a unique corresponding value of y, so this equation defines y as a function of x.
On the other hand, the equation 2x + y = 16 cannot be rearranged to solve for y in terms of x. There are infinitely many solutions for y for a given value of x, such as y = 16 - 2x, y = 16 - 2x + 5, y = 16 - 2x - 10, etc. Therefore, this equation does not define y as a function of x.
Similarly, the equation √√(x-1) = 0 does not define y as a function of x. This equation represents a square-root operation, and for a given value of x, there can be two possible values of y, one positive and one negative, that satisfy the equation. Hence, it does not define y as a function of x.
Finally, the equation y = 0 is a horizontal line where y is constantly zero, regardless of the value of x. Therefore, it does define y as a function of x.
