Answer:
-3 < x <1
Step-by-step explanation:
4 > | x + 1 | + 2
1. Isolate the absolute value;
Inverse operations;
4 > | x + 1 | + 2
-2 -2
2 > | x + 1 |
2. Remove the absolute value;
The absolute value of a value is the distance it is from zero. This means that when removing the absolute value, one has to account for two possibilities; when the value within the absolute value brackets is negative, and when it is positive. In the case of dealing with absolute value inequalities, one will have to set up an inequality with this in mind.
2 > | x + 1 |
-2 < x + 1 < 2
Inverse operations
-2 < x + 1 < 2
-1 -1
-3 < x < 1

this research seeks to identify, describe and produce an analysis of the factors that influence the learning choices of first- year undergraduate students who intend to go on to postgraduate study when they graduate, and develop associated theory.
The research explores the various factors that may influence the learning choices of first-year undergraduates, such as the family and educational background of the student, their socioeconomic status and the availability of resources, among others.
What is factor?Factor is a mathematical quantity which is multiplied with another quantity to give a product. Factors can also be defined as the numbers that divide a given number exactly. Factors are used in everyday life to calculate many different types of problems, such as compound interest, speed, distance and time, and more. Factors are also used in statistics and probability to determine the likelihood of certain events occurring.
The paper will also examine the various types of postgraduate courses that are available to undergraduates, including those offered by universities and other institutions, such as professional courses or distance learning programmes.
The research adopts a qualitative approach, and will use semi-structured interviews with first-year undergraduates to gain an understanding of their learning choices, and the factors that influence them. Interviews will be conducted with students in different disciplines, in order to gain an insight into how the different disciplines shape students' learning preferences. The research will also use questionnaires to obtain data on the socioeconomic background, family background and educational background of students.
In addition, the research will use documentary analysis of university prospectuses and websites, and information from other sources, such as employers and professional bodies, to gain an understanding of the various postgraduate courses that are available to undergraduates. This data will be used to compare and contrast the learning choices of undergraduates from different disciplines and economic backgrounds.
Finally, the research will use an interpretive approach to analyse the data collected and develop a theory of the factors that influence the learning choices of first-year undergraduates. The theory will be used to inform the design of initiatives to help undergraduates make informed decisions about their learning choices.

What is the best description of originality?
nonobvious
special or interesting
convergent
having a low probability, unique
Originality is the quality of being unique, new, and innovative. It requires creativity, imagination, inspiration, and nonobviousness. Special or interesting aspects may be present, but they are not sufficient to define originality.
Originality refers to the quality of being unique, new, and innovative. It involves creating something that has not been seen or experienced before. The best description of originality is that it is having a low probability and being unique.
An original idea, product, or work of art is something that has not been copied or imitated from others. It represents a new perspective or approach that can offer a fresh insight into a problem or challenge. Originality requires a high level of creativity, imagination, and inspiration, as well as a willingness to take risks and explore new possibilities.
Nonobviousness is also an important factor in originality. It means that the idea or invention is not something that would be obvious to someone skilled in the same field or industry. In other words, an original idea should not be something that could be easily predicted or anticipated.
Special or interesting are also characteristics of originality, but they are not sufficient to define it. An idea or product can be special or interesting without being truly original. For example, a new flavor of ice cream may be interesting, but it may not be original if it has already been created by someone else.
Convergent thinking, on the other hand, involves finding a single solution to a problem. It is the opposite of divergent thinking, which involves generating multiple ideas and possibilities. Convergent thinking is important for finding effective solutions to problems, but it is not the same as originality.
In conclusion, originality is the quality of being unique, new, and innovative. It requires creativity, imagination, inspiration, and nonobviousness. Special or interesting aspects may be present, but they are not sufficient to define originality.

You are given the great circle of a sphere is a length of 25 miles. What is the volume of the sphere
The volume of the sphere is approximately 3431.82 cubic miles.
To find the volume of a sphere, we need the radius of the sphere. The length of a great circle is the circumference of the sphere, which is related to the radius by the formula C = 2πr, where C is the circumference and r is the radius.
In this case, we are given that the length of the great circle is 60 miles. We can use this information to find the radius of the sphere.
C = 2πr
60 = 2πr
Divide both sides of the equation by 2π:
r = 60 / (2π)
r = 30 / π
Now that we have the radius, we can use the formula for the volume of a sphere:
V = (4/3)πr³
V = (4/3)π(30/π)³
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)(27000/π²)
V = (4/3)(27000/9.87) (approximating π to 3.14)
V ≈ 3431.82 cubic miles
Therefore, the volume of the sphere is approximately 3431.82 cubic miles.

Y is 275.Add any like terms together, combining x-terms with x-terms and constants with constants, on either side of the equation.
How can I locate expressions that are equivalent?Add any like terms together, combining x-terms with x-terms and constants with constants, on either side of the equation. The x-term is typically put before constants when arranging the terms in the same sequence. The two phrases are equal if each of the terms in both of them is the same.
Explanation:
x 2 + xy+xz=135; y 2 + yz+ xy=351; z 2 + xz+ yz=243; (iii)
When I (ii), and (iii) are added together, we obtain x 2 + y 2 + z 2 + 2(xy+yz+xz) = 729, which converts to (x+y+z) 2 = 27 2.
x+y+z=27
........
(iv)
According to equation I x 2 + x y + x z = 135 => x(x+y+z) = 135 => x27=135 => x=5
In equation (ii), we have y 2 + y z + x y = 351, which leads to y (x+y+z) = 351.
y×27=351 \s=>
y=13

Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)
Part B: What value of x makes the equation true? (4 points)
Answer:
Part A: First you distribute the 6(2x-11) and simplify. Then, you get the variables on the same side by subtracting 3x. Next, you do inverse operations by adding 51 to both sides and dividing 9 from both sides
Part B: x=7
Step-by-step explanation:
First thing you should do is distribute out the 6(2x-11) to get 12x-66+15=3x+12. then you simplify to get 12x-51=3x+12. Next you need to get both variable on the same side so just to keep positive number to make it easier you will subtract 3x from both sides to get 9x-51=12. now it is simple algebra where you add 51 to both sides of the equation to get 9x=63. Finally, you divide both sides by 9 to get x=7

On the first day of a family road trip, Kai's family travels 365 miles.
On the third day, they travel 20% farther.
How many miles does Kai's family travel on the third day?
Answer:
438 miles
Step-by-step explanation:
You need to find 120% of 365 because 120% would just be 100% (the starting 365 miles) + the 20% miles on the third day. 120% of 365 would be 438 miles.
Which one or more of the following pairs of displacements cannot be added to give a resultant displacement of 2 meters?
a) 1 m and 1 m
b) 1 m and 2 m
c) 1 m and 3 m
d) 1 m and 4 m
Answer is (d). 1m & 4 m. The magnitude of the result of P + Q is between P + Q and P - Q. The magnitude of the resultant is between 3 and 5 meters when the displacement is between 1 and 4 meters.
A resultant displacement is produced when displacement vectors are added. However, as long as two vectors have the same vector amount, any two vectors can be added. A resultant velocity is produced when two or more velocity vectors are added. A resultant force is created when two or more force vectors are joined together.
S = x^2 + y^2 is the displacement formula that results. For displacement, use the letter "S." The object is moving in two directions at once: X in the first direction and Y in the second. Y = 0 if your object only moves in one direction.
verify option 1:
(1,1) = P+Q = 1+1=2
P-Q = 1-1 =0
Resultant R = 2+0 = 2 (so, we can add this Option)
verify option 2:
(1,2) = P+Q = 1+2=3
P-Q = 1-2 =-1
R= 3-1= 2 (so, we can add this Option)
verify option 3:
(1,3) = P+Q = 1+3=4
P-Q = 3-1 = 2
R= 4-2= 2 (so, we can add this Option)
verify option 4:
(1,4) = P+Q = 1+4=5
P-Q = 1-4 = 2
R= 5-2= 3 (so, we can't add this Option)

The sale price of every item in a store is 85% of its usual price.
a. The usual price of a backpack is $30, what is its sale price? $
25.5
b. The usual price of a sweatshirt is $18, what is its sale price? $
Answer
a. The backpack is $4.50
b. The sweatshirt is $2.70
Step-by-step explanation:
a. 30 x 0.15 = 4.50 (The 0.15 is from the price you are actually paying for the item. Because the item is 85% off, you are paying for 15% of the usual price. 15% as a decimal is 0.15 so you multiply that to the original price to find the amount u will pay.)
b. 18 x 0.15 = 2.70
Suppose a man invested $300 at the end of 1900 in each of three
funds that tracked the averages of stocks, bonds, and cash,
respectively. Assuming that his investments grew at the rates
given in the table to the right, approximately how much would
each investment have been worth at the end of 2010?
Category
Stocks
Bonds
Cash
His investment in the fund tracking stocks would be worth approximately $
(Do not round until the final answer. Then round to two decimal places as needed.)
Average Annual Return
6.4%
1.7%
0.7%
Answer:
To calculate the value of each investment at the end of 2010, we need to use the compound interest formula:
A = P(1 + r/n)^(nt)
where:
A = the final amount
P = the initial investment
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
For the investment in the fund tracking stocks:
P = $300
r = 6.4% = 0.064
n = 1 (assuming the interest is compounded annually)
t = 2010 - 1900 = 110
A = 300(1 + 0.064/1)^(1*110) = $208,884.78 (rounded to the nearest cent)
For the investment in the fund tracking bonds:
P = $300
r = 1.7% = 0.017
n = 1
t = 2010 - 1900 = 110
A = 300(1 + 0.017/1)^(1*110) = $2,326.34 (rounded to the nearest cent)
For the investment in the fund tracking cash:
P = $300
r = 0.7% = 0.007
n = 1
t = 2010 - 1900 = 110
A = 300(1 + 0.007/1)^(1*110) = $862.38 (rounded to the nearest cent)
Therefore, the investment in the fund tracking stocks would be worth approximately $208,884.78 at the end of 2010, the investment in the fund tracking bonds would be worth approximately $2,326.34, and the investment in the fund tracking cash would be worth approximately $862.38.

Shannon was born on 04/02/2004. How many eight-digit codes could she make using the digits in her birthday?
Answer: 420 different codes.
Step-by-step explanation:
We have eight digits, {0, 0, 0, 0, 2, 2, 4, 4}
For the first digit of the code, we will have 8 options.
For the second we will have 7 options (because we already took one)
for the third one we will have 6 options, and so on.
for the fourth, we will have 5 options
for the fifth, there are 4 options.
for the sixth, there are 3 options.
for the seventh, there are 2 options.
And for the last, there is only one option.
The total number of combinations will be equal to the product between the numbers of options for each digit, then we will have:
C = 8*7*6*5*4*3*2*1
But there is something more, the zeros can permute and will give the same code (So we are counting the same code several times), we have 4 zeros, then the number of permutations of the zeros is:
4*3*2*1 = 24
the 4's also are repeated, two times in this case, the number of permutations is:
2*1 = 2
And the 2's also are repeated, also two times, the number of permutations is:
2*1 = 2
Because we do not want to count these repetitions, we need to divide the total number of combinations by these 3 numbers of permutations
This means that we need to divide the number of different combinations will be:
c = (8*7*6*5*4*3*2*1)/(24*2*2) = 420
So we can conclude that there are 420 different codes.
The number of eight digit codes she can make using the digits in her birthday is; 420 eight digit codes
The 8 digits code of her birth date are;
0, 4, 0, 2, 2, 0, 0, 4
Now, since there are 8 digits, then number of ways of arranging the 8 digits is 8!
Since there are some repetitions, then we have to consider the permutations for them too.
There are four 0's which is 4!
There are two 2's which is 2!
There are two 4's which is 2!
Thus, number of 8 digit codes she can make using the digits on her birthday is;
8!/(4! × 2! × 2!) = 420 eight digit codes

2. Yesterday, there was less than 25 inches of snow. _________________
3. The temperature tomorrow will be no more than 8 °F. _________________
4. The temperature today will be at least 7 °F. _________________
Answer:
The symbols that we will use are:
a > b (a is larger than b)
a < b (a is smaller than b)
a ≥ b (a is larger than or equal to b)
a ≤ b (a is smaller than or equal to b).
1) if x represents the inches of snow, we have:
"More than 4 inches" means that x must be strictly larger than 4 inches, this can be written as:
x > 4 inches.
2) "less than 25 inches" means that x must be strictly smaller than 25 inches, this can be written as:
x < 25 inches.
3) If T represents the temperature
"No more than 8°F" means that the temperature can be smaller than 8°F, or equal to 8°F, then we can write this situation with:
T ≤ 8°F
4) "At least 7°F" means that the temperature can be 7°F or more than that, then we can write this situation as:
T ≥ 7°F
Relative intensity of 9 decibels is how many times higher than that of 8 decibels
Answer:
what do you mean by land ?
The intensity of sound is proportional to the square of its amplitude.
Thus, if I9 and I8 are the intensities of sounds at 9 decibels and 8 decibels respectively, then:
I9/I8 = (10^(9/10))/(10^(8/10))
I9/I8 = 10^(0.1)
I9/I8 = 1.2589
Therefore, the relative intensity of 9 decibels is approximately 1.26 times higher than that of 8 decibels.
