a. In the general education course requirement at a college, a student needs to choose one each from social sciences, humanities, natural sciences, and foreign languages. There are 5 social science courses, 4 humanity courses, 4 natural science courses, and 3 foreign language courses available for general education. How many different ways can a student choose general education courses from these 4 areas?
Using the Fundamental Counting Theorem, there are 240 ways to choose general education courses from these 4 areas.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with \(n_1, n_2, \cdots, n_n\) ways to be done, each thing independent of the other, the number of ways they can be done is:
\(N = n_1 \times n_2 \times \cdots \times n_n\)
Considering the number of options for each course, the parameters are given as follows:
\(n_1 = 5, n_2 = 4, n_3 = 4, n_4 = 3\).
Hence the number of ways is given by:
N = 5 x 4 x 4 x 3 = 240.

Jody's team scored 21, 25, 36, 16, and 32 points at the last five football games. What is the mean number of points Jody's team scored? 20 points 21 points 25 points 26 points
Answer:
26 points
Step-by-step explanation:
Find the mean number of points by adding up all of the points and dividing it by 5
(21 + 25 + 36 + 16 + 32) / 5
130 / 5
= 26
So, the mean number of points is 26 points
Jody's team scored 21, 25, 36, 16 and 32 points at the last five football games. What is the mean number of points Jody's team scored ?
Solution:-To find the mean, first of all we have to add up all the given points and then divide by how many number of points there are. So, there are total 5 points. Hence, we have to divide all the given points by 5.
So, Mean = \( \bf \frac{21 \: + \: 25 \: + \: 36 \: + \: 16 \: + \: 32}{5} \)
Mean = \( \bf \frac{130}{5} \)
Mean = \( \bf 26 \)

The equation 9cos(sin¯¹(x)) = √(81 – 81x²) is true since L.H.S = R.H.S
To answer the question, we need to know what an equation is
What is an equation?An equation is a mathematical expression that show the relationship between two variables.
Given 9cos(sin¯¹(x)) = √(81 – 81x²), we need to show L.H.S = R.H.S
So, L.H.S = 9cos(sin¯¹(x))
= 9[√{1 - sin²(sin¯¹(x)}] (Since sin²y + cos²y = 1 ⇒ cosy = √[1 - sin²y])
9[√{1 - sin²(sin¯¹(x)}] = √9² × √{1 - sin²(sin¯¹(x)}]
= √[9² × {1 - sin²(sin¯¹(x)}]
= √[81 × {1 - sin²(sin¯¹(x)}]
= √[81 × {1 - x²}] (since sin²(sin¯¹(x) = [sin(sin¯¹(x)]² = x²)
= √(81 – 81x²)
= R.H.S
So, the equation 9cos(sin¯¹(x)) = √(81 – 81x²) is true since L.H.S = R.H.S

In an ESP experiment subjects must predict whether a number randomly generated by a computer will be odd or even. (Round your answer to four decimal places.) (b) What is the probability that a subject would guess more than 20 correct in a series of 36 trials?
The probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001
How to find the pobability that a subject would guess more than 20 correct in a series of 36 trialsIn a series of 36 trials, if the subject is guessing randomly, then the probability of correctly guessing odd or even is 1/2.
Let X be the number of correct guesses in a series of 36 trials. X follows a binomial distribution with parameters n = 36 and p = 1/2.
The probability of guessing more than 20 correct is:
P(X > 20) = 1 - P(X ≤ 20)
Using a binomial distribution table, we can find that P(X ≤ 20) = 0.9999 (rounded to four decimal places).
Therefore: P(X > 20) = 1 - 0.9999 = 0.0001
So the probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001 (rounded to four decimal places).

Answer:
he can buy 8 of lilies and 12 of rose and 48 of daisies
Ali can buy 3 flowers of lilies, 3 flowers of roses, and 18 flowers of daisies.
Suppose Ali buys x flowers of lilies, y flowers of roses, and z flowers of daisies.
According to the question
x+y+z = 24......(1)
3x+2y+0.5z = 24.......(2)
Here, we have three variables but only two equations.
2(2)-(1) gives, 5x+3y = 24......(3)
Since, x, y and z can take only integer values.
What are integers?Numbers that are not fractions called integers.
So, from (3) only x=3 and y=3 is possible
So, z= 24-x-y
z=24-3-3 = 18
So, Ali can buy 3 flowers of lilies, 3 flowers of roses, and 18 flowers of daisies.

20. Rafael has a business selling computers. He buys computers from the manufacturer for $450
each and sells them for $800. Each month, he must also pay fixed costs of $3000 for rent and
utilities at his store. If he sells n computers in a month, which of the following equations can be used
to calculate his profit?
A. P = n(800 - 450)
B. P = n(800 - 450 - 3000)
C. P = 3000n(800 - 450)
D. P = n(800 - 450) - 3000
E. P = n(800 - 450) + 3000
Yeah
Answer: D , p = n (800 - 450) - 3000
Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation
P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).
The equation that represents Rafael's monthly profit selling 'n' numbers of computers is D. P = n(800 - 450) - 3000.
What is an equation?An equation represents equality for the terms that are on the both side of the equal sign.
Given Rafael buys computers for 450 dollars and sells them for 800 dollars each.
He also had to pay 3000 dollars for rent and utilities for the store and the number of computers sold in each month is given by 'n'.
∴ The equation that represents his profit(P) in a month is,
P = n(800 - 450) - 3000.

What is statistical inference? Why is it important?
(In your own words, please! ) Thanks!
Statistical inference is the process of using data from a sample to make generalizations or draw conclusions about a larger population.
What is statistical Inference?Based on the sample data, assumptions are made about the fundamental traits of the population, and the uncertainty in those assumptions is quantified using statistical techniques.
Because it enables us to forecast the future and make judgements based on incomplete data, statistical inference is crucial. For instance, with a sample of data, it enables us to confidently estimate population parameters such as averages and proportions. This can be helpful in a variety of contexts, including marketing analysis, surveys of public opinion, clinical trials, and manufacturing quality control.
By comparing the results of several groups or treatments, statistical inference also enables us to assess the efficacy of interventions or treatments.This can inform decisions about which treatments are most effective or which interventions should be implemented.

The image shows a geometric representation of the function f(x) = x2 – 2x – 6 written in standard form.
This function written in vertex form include the following: A. f(x) = (x –1)² – 7.
How to determine the axis of symmetry and vertex of a quadratic function?In Mathematics, the axis of symmetry of a quadratic function can be calculated by using this mathematical equation:
Axis of symmetry = -b/2a
Where:
a and b represents the coefficients of the first and second term in the quadratic function.
For the given quadratic function f(x) = x² – 2x – 6, we have:
a = 1, b = -2, and c = -6
Axis of symmetry, Xmax = -b/2a
Axis of symmetry, Xmax = -(-2)/2(1)
Axis of symmetry, Xmax = 2/2
Axis of symmetry, Xmax = 1.
Next, we would determine vertex as follows;
f(x) = x² – 2x – 6
f(x) = 1² – 2(1) – 6
f(x) = -7.
Now, we can write quadratic function in vertex form;
f(x) = a(x - h)² + k
f(x) = (x - 1)² - 7

27 pounds 72
What is a proportion?
A percentage is created when two ratios are equal to one another. We write proportions to construct equivalent ratios and to resolve unclear values. a comparison of two integers and their proportions. According to the law of proportion, two sets of given numbers are said to be directly proportional to one another if they grow or shrink in the same ratio.
We have,
3 pounds bag of cheese makes 8 pizzas.
This means,
3 pounds = 8 pizzas
1 pound = 8/3 pizzas
Now,
1 pound = 8/3 pizzas
Multiply 18 on both sides.
18 pounds = 18 x 8/3
18 pounds = 48 pizzas
1 pound = 8/3 pizzas
Multiply 22.5 on both sides.
22.5 pounds = 22.5 x 8/3
22.5 pounds = 60 pizzas
1 pound = 8/3 pizzas
Multiply 27 on both sides.
27 pounds = 27 x 8/3
27 pounds = 72 pizzas
Thus,
The number of Pizzas for 3 pounds is 8.
The number of Pizzas for 18 pounds is 48.
The number of Pizzas for 22.5 pounds is 60.
The number of Pizzas for 27 pounds is 71.
