The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of one side of the cube. Find the surface area and the volume of a cube with a side length of 4 meters.
Answers
Answer:
surface area of the cube is 96m² and the volume is 64m³
Step-by-step explanation:
Surface area of the cube = 6x²
x is the side length
Given
x = 4metres
Surface area of the cube = 6(4)²
Surface area of the cube = 6(16)
Surface area of the cube = 96m²
Volume of the cube = x³
Volume of the cube = 4³
Volume of the cube = 64m³
Hence the surface area of the cube is 96m² and the volume is 64m³

Given: The dimension of the right-trinagle as
\(\begin{gathered} H_{\text{ypothenuse}}=24\text{inches} \\ O_{ne\text{ of the legs of the triangle}}=12inches \end{gathered}\)To Determine: The second leg of the triangle to the nearest tenth
Solution:
Let us represent the given using a right-triangle
The hypothenuse is the logest side and the side facing the right angle
Applying pythagoras theorem which state that the square of the hypothenuse is equal to the sum of the squares of the other sides
Let the other leg be y
Therefore
\(y^2+12^2=24^2\)\(\begin{gathered} y^2+144=576 \\ y^2=576-144 \\ y^2=432 \end{gathered}\)\(\begin{gathered} y^2=432 \\ y=\sqrt[]{432} \\ y=20.7846 \\ y\approx20.8inches \end{gathered}\)Hence, the second leg of the triangle is 20.8 inches rounded to the nearest tenth
records show that 10% of all college students are foreign students who also smoke. it is also known that 40% of all foreign college students smoke. what percent of the students at this university are foreign?
Answers
The percentage of the students at the university which are foreign are 25% by conditional probability formula.
According to the question, 10% of all college students are foreign students who also smoke and it is also known that 40% of all foreign college students smoke.
We use the conditional probability formula to solve this question.
Let foreign students be denoted as F
Let students smoking be denoted as S
We know that 10% of all college students are foreign students who also smoke this means
P(F ∩ S) = 0.1
and 40% of all foreign college students smoke which means
P(S/F) = 0.4
So, the percentage of the students at this university who are foreign can be calculated as
\(P(F) = \frac{0.1}{0.4}\) = 0.25

You perform a Chi-Square test and obtain a p-value lower than 0.01. What does that mean?
Answers
Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.
If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.
The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.
In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.

Answers
To evaluate the given Boolean equation F = (a) AND NOT(b OR NOT(c)) for each set of variable values:
The Boolean equation F=(a) AND NOT(b OR NOT(c)) can be simplified as follows:
F = a AND (NOT b AND c)
The value of F depends on the values of a, b, and c.
Case A: a=0, b=0, c=0
In this case, F = 0 AND (NOT 0 AND 0) = 0 AND 0 = 0.
Case B: a=1, b=0, c=1
In this case, F = 1 AND (NOT 0 AND 1) = 1 AND 1 = 1.
Case C: a=1, b=1, c=0
In this case, F = 1 AND (NOT 1 AND 0) = 1 AND 0 = 0.
Case D: a=1, b=1, c=1
In this case, F = 1 AND (NOT 1 AND 1) = 1 AND 1 = 1.

For every p prime number, are there any q and r prime numbers such that 2p=q+r (q and r are different, and p is not 2 or 3)?
Answers
Yes, there are always prime numbers q and r, which are different from one another for every p prime number when 2p = q + r, where q and r are different from one another and p is not 2 or 3.
An even number can always be represented as the sum of two prime numbers according to the Goldbach conjecture. 2p can also be represented as the sum of two distinct prime numbers (q and r).However, we must exclude the following possibilities: p = 2, 3, or 2p is an even composite number.
Because for 2, the only even prime number, there is no way to represent 4 as the sum of two different prime numbers. Similarly, 3 + 3 is the only way to represent 6 as the sum of two distinct prime numbers.
And finally, for 2p being an even composite number, the Goldbach conjecture only refers to even numbers, and there is no proof for odd numbers such as 2p. So, these possibilities have been ruled out.
In the remaining cases, we have the following observation
Therefore, for every p prime number, there are prime numbers q and r that are different from one another for every p prime number when 2p = q + r, and p is not 2 or 3.
Summary: For every p prime number, there are always prime numbers q and r, which are different from one another when 2p = q + r, where q and r are different from one another and p is not 2 or 3.

Program State Model describes a precise mathematical description of the semantics of an executing program.
This model is used to illustrate how the program executes and to determine its behavior. It is composed of three components: states, transitions, and actions. A program state is a snapshot of the program's state at a particular point in its execution. It includes the values of variables and other resources. Transitions are the changes that occur between states, and are caused by the execution of instructions. Finally, actions are the operations that are performed by the program as it transitions from one state to the next. All of these components together provide a mathematical model for understanding the behavior of a program.

Enter your answers in decimal form by filling in the boxes.
Absolute value inequality:
A bead can be no shorter than

cm.
Answers
The range of lengths is given by the inequality:
4.1 in ≤ L ≤ 4.5 in
What is the acceptable range of lengths?
We know that the length of a manufactured ceramic bead is 4.3 centimeters, with an acceptable error of 0.2 inches.
This means that the length of the ceramic bead can be, at most, 0.2 inches away (lower or upper) from 4.3 in.
Then the smaller length allowed is:
4.3 in - 0.2 in = 4.1 in
The largest length allowed is:
4.3 in + 0.2in = 4.5in
Then the range of lengths is given by the inequality:

Answers
To determine the landing point, we need to balance the time it takes to row the boat with the time it takes to walk.
The woman's rowing speed is 3 km/h, and her walking speed is denoted as w km/h. Let d be the distance from the island to the landing point, and x be the distance she needs to walk from the landing point to reach the town. The total time for rowing (d/3) should be equal to the total time for walking [(12 - x)/w] in order to arrive at the town.
By rearranging the equation, we find that the landing point should be 12 km minus the distance covered by walking (d * w) divided by 3.
The exact value of x depends on the specific distances involved and the woman's walking speed, which are not provided in the given information.

Find a polynomial function of degree 3 with the given numbers as zeros. Assume that the leading coefficient is 1.
-1/2, 0, 1
The polynomial function is f(x)= ___
(Simplify your answer. Use integers or fractions for any numbers in the expression)
Answers
The polynomial function of degree 3 with the zeros -1/2, 0, and 1 is:
f(x) = x^3 - (1/2)x^2 - (1/2)x
To find a polynomial function of degree 3 with the zeros -1/2, 0, and 1, we can start by using the zero-product property. Since the leading coefficient is assumed to be 1, the polynomial can be written as:
f(x) = (x - (-1/2))(x - 0)(x - 1)
Simplifying this expression, we have:
f(x) = (x + 1/2)(x)(x - 1)
To further simplify, we can expand the product:
f(x) = (x^2 + (1/2)x)(x - 1)
Multiplying the terms inside the parentheses, we get
f(x) = (x^3 + (1/2)x^2 - x^2 - (1/2)x)
Combining like terms, we have:
f(x) = x^3 - (1/2)x^2 - (1/2)x
Therefore, the polynomial function of degree 3 with the zeros -1/2, 0, and 1 is:
f(x) = x^3 - (1/2)x^2 - (1/2)x
