The expression that represents the volume of the prism is 30x² cubic units.
Option D) is the correct answer.
What is a prism?A prism is simply a solid geometric with two polygonal faces laying in parallel planes and with the other faces parallelograms.
Volume of a prism is expressed as;
Volume = base area × height
Also, the base area is expressed using the area of a trapezoid.
Hence,
Base area = (1/2) × h( a + b )
Now, let;
h = xa = xb = 2xBase area will be;
Base area = (1/2) × h( a + b )
Base area = (1/2) × x( x + 2x )
Base area = (1/2) × 3x²
Base area = 3x²/2
Now volume will be;
Volume = base area × height
Volume = 3x²/2 × h
So, let h be 20 units
Volume = 3x²/2 × 20uniit
Volume = 60x²/2
Volume = 30x² cubic units
Therefore, the expression that represents the volume of the prism is 30x² cubic units.
Option D) is the correct answer.

Describe in detail the most memorable visual aid you've ever seen used in a presentation. why does it stick out in your memory? how was it used to illustrate a point? what did you learn from this experience?
Answer:
Explanation:
The most memorable visual aid I have seen used was when a psychology professor used graphic descriptions (through historically important paintings) to illustrate abstract concepts, such as love, madness, and despair.
The representations used in the presentation stuck in my mind because of the visual impact that correlated with my personal experiences, making them vivid and memorable in my mind.
The points illustrated aimed at demonstrating the universality of human passions, and as such, it was an extremely successful presentation.
Finally, what I learned from this experience is that human emotions are not only universal, and as such, they can be represented, but, also, and most importantly, they are emotions that are not abstract concepts, rather, singular and personal experiences to which, paradoxically, everyone is subjected.

Answer:
A better shelter and A. clean water lead to growth of global population.
Explanation:
Availability of a good shelter and clean water both help an individual lead a healthy life. The shelter protects him from external environmental factors that may be harmful to his existence. These factors include sunlight, rains, lightning, etc.
Clean water keeps the water-borne diseases away and helps the individual maintain hygiene which is ultimately necessary for his physical well-being. Thus, the availability of shelters and clean water increase the life expectancy and ultimately result in global population growth.

Which system of equations models the paths of the two skaters? y = 0.08x2-1.6x+13 and y = 0.08(x-10)2+5 y = 0.08x2-1.6x+13 and y = 1.6(x-10)2+5 y = 0.08x2-1.6x+13 and y = 0.8(x-10)2+5 y = 0.08x2-1.6x+13 and y = 5(x-10)2+5
The system of equations models the paths of the two skate is y = 0.08x²-1.6x+13 and y = 5(x-10)²+5. The correct option is b.
What is quadratic equation?The equation with second degree of an unknown variable x, y, m, n, or p is called the quadratic equation.
David starts at (20, 13) and skates along a path that can be modeled by a quadratic equation with a vertex at (10, 5).
Vertex form of quadratic equation is
y =a (x -h)² +k where (h,k) is the vertex.
We plug in (10,5) for h and k
y= a (x -10)² +5
Now plug in (20,13) in the above equation and find out 'a'
13 = a (x -10)² +5
13 = a(10)² +5
13 = 100a + 5
Solving for a, we get
a = 0.08
Substitute 0.08 for 'a' then the equation becomes
y= 0.08 (x -10)² +5
Thus, the correct option is b.

Of 1000 students surveyed, 490 were boys and 320 had bicycles. of those who had bicycles, 130 were girls. what is the probability that a student surveyed was either a boy or had a bicycle?
By definition of probability, the probability that a student surveyed was either a boy or had a bicycle is 62%.
Definition of ProbabitityProbability is the greater or lesser possibility that a certain event will occur.
In other words, the probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.
Union of eventsThe union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".
The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:
P(A∪B)= P(A) + P(B) -P(A∩B)
The intersection of events, A ∩ B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.
Events and probability in this caseIn first place, let's define the following events:
A: The event that a student surveyed was a boy.B: The event that a student surveyed had a bicycle.Then you know:
P(A)= [tex]\frac{490}{1000}[/tex]=0.49= 49%P(B)= [tex]\frac{320}{1000}[/tex]= 0.32= 32%P(A and B)= P(A∩B)= [tex]\frac{190}{1000}[/tex]= 0.19= 19% [320 students had bicycles. Of those who had bicycles, 130 were girls. Then, 190 were boys.]In this case, considering the definition of union of eventes, the probability that a student surveyed was either a boy or had a bicycle is calculated as:
P(A∪B)= P(A) + P(B) -P(A∩B)
P(A∪B)= 0.49 + 0.32 -0.19
P(A∪B)= 0.62= 62%
Then, the probability that a student surveyed was either a boy or had a bicycle is 62%.

While individuals can violate these rights, the leadership or government of civilization most often belittles marginalized persons. Abductions, arbitrary arrests, detentions without trial, political executions, assassinations, and torture often follow. In cases where extreme violations of human rights have occurred, reconciliation and peacebuilding become much more difficult.

A random drawing will determine which 3 people in a group of 9 will win concert tickets. what is the probability that you and your 2 friends will win the tickets? express your answer as a fraction in simplified form.
The probability that you and your 2 friends win the tickets is P = 1/84.
How to determine the probability?
There are 9 possible outcomes, 3 of which are you and your friends.
All of these outcomes have the same probability of being randomly selected, then the probability of winning is given by the quotient between the number of "outcomes" that you have and the total number of outcomes.
Let's say that the outcomes are pieces of paper with the names of the participants.
First draw:
In this one, there are 3 possible options that work, one is your paper, and the other two are for your friends.
So the probability is 3/9 = 1/3.
Second draw.
One of your group already won, so now there are 2 of you, and a total of 8 pieces of paper, so this time the probability is 2/8 = 1/4
Final draw:
Only one of you remains, and there is a total of 7 pieces of paper, this time the probability is 1/7.
The joint probability (of these 3 events happening in succession) is given by the product of the individual probabilities:
P = (1/3)*(1/4)*(1/7) = 1/84

How many grams of calcium oxide will be produced in a closed vessel containing 20.0 kg of calcium and 20.0 kg of oxygen gas if the reaction goes to completion? (atomic mass of calcium = 40.1 amu)
Answer:
Explanation:
The mass of Calcium oxide that will be produced in a closed vessel is 27984.1311 g. The Number of moles is defined as given mass over molar mass.
Calculation of Number of moles:
Number of moles = Given mass / Molar mass
For Calcium :-
Mass of calcium = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of calcium = 40.078 g/mol
Thus,
Number of moles = 20000 g / 40.078 g/mol
Number of moles = 499.02 moles
For oxygen gas :-
Mass of oxygen gas = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of oxygen gas = 31.999 g/mol
Thus,
Number of moles = 20000 g / 31.999
Number of moles = 625.19 moles
According to the given reaction:
2 moles of calcium reacts with 1 mole of oxygen gas
Also,
1 mole of calcium reacts with 1/2 mole of oxygen gas
So,
499.0269 mole of calcium react with mole of oxygen gas
Moles of oxygen gas = 249.5135 moles
Available moles of oxygen gas = 625.0195 moles
Limiting reagent is the one which is present in small amounts. Thus, calcium is limiting reagent.
The formation of the product is governed by the limiting reagent. So,
2 moles of calcium produces 2 moles of calcium oxide
So,
1 mole of calcium produces 1 mole of calcium oxide
Also,
499.0269 moles of calcium produces 499.0269 moles of calcium oxide
Moles of calcium oxide = 499.0269 moles
Molar mass of calcium oxide = 56.0774 g/mol
Mass of calcium oxide = Moles × Molar mass = 499.0269 * 56.0774 g = 27984.1311 g
27984.1311 g of calcium oxide will be produced.
