A computer is an electronic device that performs various processing tasks very quickly and efficiently. It involves a combination of hardware, software, and input/output devices to process, store, and retrieve information. A computer system consists of several components, including the central processing unit (CPU), memory, storage devices, input/output devices, and communication channels. Computers can perform a wide range of activities, such as data processing, calculations, gaming, browsing the internet, and creating multimedia content. They have become an essential tool in almost every industry, ranging from education, healthcare, finance, entertainment, and more.
bot
A bot, short for "robot" is a computer program designed to automate repetitive tasks, simulate human behavior, or perform specific functions. Bots are typically used to perform tasks that are too tedious, time-consuming, or complex for humans to do, such as web scraping, data entry, and social media management. They can also be used for conversational purposes, such as chatbots, which are designed to provide customer service or communicate with users in a natural language interface. Bots can operate autonomously or be controlled by humans, and they can be programmed to carry out a wide variety of tasks. Some bots are beneficial, while others can be harmful, depending on their use, design, and purpose.

A popular art teacher at a school asks a sample of students if they would be interested in taking an art class next year. Of the 30 students he asks, 85% are in one of his art classes this year. Only 15% of the students in the school are in one of his art classes this year. Will this sample be biased?
*

Yes, because students who are in one of his art classes this year will be more likely to take one of his art classes next year.
No, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.

Out of the 400 spectators surveyed, 140 were women.
To estimate the number of women at the event, you can use proportional reasoning as follows:
140/400 = x/8000, where x represents the number of women at the event.
Solving for x, we get:
x = (140/400)*8000 = 2,800
Therefore, the estimated number of women at the event is 2,800.

Suppose there are 8,000 people at a basketball game. You survey a random sample of 400 spectators and gather the following information: Estimate the number of people at the event who are under 30 years old.
Out of the 400 spectators surveyed:
- 220 were under 30 years old (80 females and 140 males)
- 180 were 30 years old or older (60 females and 120 males)
To estimate the number of people at the event who are under 30 years old, you can use proportional reasoning as follows:
220/400 = x/8000, where x represents the number of people under 30 years old at the event.
Solving for x, we get:
x = (220/400)*8000 = 4,400
Therefore, the estimated number of people who are under 30 years old at the event is 4,400.
- 220 were under 30 years old (80 females and 140 males)
- 180 were 30 years old or older (60 females and 120 males)

The function rule for the table is f(x) = x^2 + 2x + 1.
To verify:
- When x = 3, f(x) = 3^2 + 2(3) + 1 = 9 + 6 + 1 = 16
- When x = 4, f(x) = 4^2 + 2(4) + 1 = 16 + 8 + 1 = 25
- When x = 5, f(x) = 5^2 + 2(5) + 1 = 25 + 10 + 1 = 36
- When x = 6, f(x) = 6^2 + 2(6) + 1 = 36 + 12 + 1 = 49
So the function rule f(x) = x^2 + 2x + 1 correctly outputs the values in the table.

12d + 0.3
H(d) = 0.3d
H(d) = 0.3 + 12
The rule to describe the function is:
H(d) = 0.3d + 12
where H represents the height of the zucchini plant (in centimeters) and d represents the number of days since it was first planted.

d(t) = t + 0.5; b. 4.3 meters
d(t) = 0.5t + 1; b. 4.1 meters
d(t) = 0.5t; b. 4.2 meters
a. The rule to describe the function is:
d(t) = 0.5t
where d represents the distance traveled (in meters) and t represents the time elapsed (in minutes).
b. To find out how far the sloth will travel in 8 minutes, we can substitute t with 8 in the function:
d(8) = 0.5(8) = 4
Therefore, the sloth will travel 4 meters in 8 minutes.
Correct answer is: d(t) = 0.5t; b. 4 meters
d(t) = 0.5t
where d represents the distance traveled (in meters) and t represents the time elapsed (in minutes).
b. To find out how far the sloth will travel in 8 minutes, we can substitute t with 8 in the function:
d(8) = 0.5(8) = 4
Therefore, the sloth will travel 4 meters in 8 minutes.
Correct answer is: d(t) = 0.5t; b. 4 meters
Which function is greatest at x = 2?
* f x=3x
fx=x3
fx=2.x3
none of the others
* f x=3x
fx=x3
fx=2.x3
none of the others
f(x) = x^3 is the greatest at x = 2.
When x = 2:
- f(x) = 3x = 3(2) = 6
- f(x) = x^3 = 2^3 = 8
- f(x) = 2x^3 = 2(2^3) = 16
Therefore, the function f(x) = 2x^3 is the greatest at x = 2.
When x = 2:
- f(x) = 3x = 3(2) = 6
- f(x) = x^3 = 2^3 = 8
- f(x) = 2x^3 = 2(2^3) = 16
Therefore, the function f(x) = 2x^3 is the greatest at x = 2.
