Alex and Lara have $21.00. each to spend at a book fair, where all students receive a 35% discount. They both want to purchase a copy of the same book, which normally sells for $28.50 plus 10% sales tax. To check if he has enough to purchase the book, Alex takes 35% of $28.50 and subtract that amount from the normal price. He takes 10% of the discounted selling price and adds it back to find the purchase amount. Lara takes 65% of the normal purchase price and then computes 110% of the reduced price. Is Alex correct? Is Lara correct? Do they have enough money to purchase the book? explain your answer using complete sentences and show your work.
To begin, let's find how much the book is including tax and the student discount. Once we find this, we can see if Lara or Alex is correct and if they can afford it.
First, we want to compute the student discount. The student discount is 35%. Thus, we can do 0.65 x 28.50 = 18.525. With 10% tax, we have 18.525 x 1.1 = 20.3775. Which will round up to $20.38.
Now, lets see what Alex did and if he got the same answer. First he takes 35% of $28.50 and subtracts it from the normal price.
.35 x 28.50 = 9.975
28.50 - 9.975 = 18.525
Then he takes 10% of this number and adds it back.
.10 x 18.525 = 1.8525
18.525 + 1.8525 = 20.3775
Alex has the correct answer.
Next, we will see if Lara computed it correctly.
First she takes 65% of the normal price.
0.65 x 28.50 = 18.525
Then she computes 110% of the reduced price.
18.525 x 1.10 = 20.3775
Lara also gets the correct answer.
So, do they have enough money to purchase the book?
YES:
$20.38 < $21
Is Alex correct?
YES
Is Lara correct?
YES
Although they used different methods to get the answer, they both got the right one!

To find the distance between two cities on the map, we can use the formula provided in the question:
d = 250n
where d is the actual distance between the cities in miles, and n is the number of inches on the map. Since we are given that the actual distance between the two cities is 1,125 miles, we can substitute this value for d in the formula above to find the number of inches on the map:
1,125 = 250n
Solving for n, we get:
n = 1,125 / 250 = 4.5 inches
This means that the distance between the two cities on the map should be 4.5 inches, so the correct answer is (D) 4.5 inches.

Answer:
To answer these questions, we need to first calculate the total number of payments you have made over the past 3 years. We can do this by multiplying the number of payments per year (12) by the number of years (3). This gives us a total of 36 payments.
Next, we can use a financial calculator or spreadsheet program to solve for the remaining balance on your loan after making 36 payments of $327.51 each. In a financial calculator, we can enter the following values:
N: 36
I: 5.8
PV: -14000
PMT: 327.51
FV: 0
Solving for PV gives us a remaining balance of $4,819.56. Therefore, the answer to part A is $4,819.56.
To find your equity in the car, we can subtract the remaining balance on the loan from the value of the car. In this case, your equity would be $7,500.00 - $4,819.56 = $2,680.44. Therefore, the answer to part B is $2,680.44.

Which are four types of probability sampling methods?
The four types of probability sampling methods are
1. Simple random sampling
2. Stratified sampling
3. Systematic sampling
4. Cluster sampling
Probability sampling is a sampling method that involves randomly selecting a sample, or a part of the population that you want to research.
1. Simple Random Sampling: Simple random sampling gathers a random selection from the entire population, where each unit has an equal chance of selection. This is the most common way to select a random sample.
2. Stratified Sampling: Stratified sampling collects a random selection of a sample from within certain strata, or subgroups within the population. Each subgroup is separated from the others on the basis of a common characteristic.
3. Systematic Sampling: Systematic sampling draws a random sample from the target population by selecting units at regular intervals starting from a random point. This method is useful in situations where records of target population already exist.
4. Cluster Sampling: Cluster sampling is the process of dividing the target population into groups, called clusters. A randomly selected subsection of these groups then forms the sample. It usually involves existing groups that are similar to each other in some way

We observe that there are p² polynomials of the form x² + ax + b in Zp.
Since there are p choices for each of a and b.
Now a polynomial which is reducible over Zp may be rewritten in the form
(x - c)(x - d)
where c and d are roots.
So there are p choices if c = d
and if c ≠ d then there are [tex]\frac{p(p-1)}{2}[/tex] choices, the division of 2 eliminates repeated pairs.
Therefore there are p² - ( p + [tex]\frac{p(p-1)}{2}[/tex]) polynomials irreducible over Zp.
A polynomial is said to be irreducible if it cannot be factored into nontrivial polynomials over the same field. The property of irreducibly depends on the field or ring to which the coefficients are considered to belong.

Let g(x)=x²-1.
(a) Find the average rate of change from 2 to 6.
(b) Find an equation of the secant line containing (-2, g(-2)) and (6, g(6)).
Answer:
Step-by-step explanation:
To find the average rate of change from 2 to 6, we can use the formula for the average rate of change, which is given by (y2 - y1) / (x2 - x1). In this case, the function we are working with is g(x) = x² - 1, so we need to plug in the values of x1 and x2 into the function to get the corresponding values of y1 and y2.
a) The average rate of change from 2 to 6 is given by:
(g(6) - g(2)) / (6 - 2)
Plugging in the values of x1 and x2 into the function g(x), we get:
(g(6) - g(2)) / (6 - 2) = (6² - 1 - 2² + 1) / (6 - 2) = (35 - 3) / 4 = 32 / 4 = 8
Therefore, the average rate of change from 2 to 6 is 8.
b) To find an equation of the secant line containing the points (-2, g(-2)) and (6, g(6)), we need to first find the slope of the secant line. The slope of the secant line is given by the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points on the secant line.
In this case, the coordinates of the two points on the secant line are (-2, g(-2)) and (6, g(6)). Plugging these values into the formula for the slope, we get:
m = (g(6) - g(-2)) / (6 - (-2)) = (6² - 1 - (-2)² + 1) / (6 + 2) = (35 + 5) / 8 = 40 / 8 = 5
Now that we know the slope of the secant line, we can use the point-slope form of a line to write the equation of the secant line. The point-slope form of a line is given by the formula y - y1 = m(x - x1), where (x1, y1) is a point on the line, m is the slope of the line, and (x, y) are the coordinates of a generic point on the line.
In this case, we know that the point (-2, g(-2)) is on the secant line, and we know that the slope of the secant line is 5. Plugging these values into the point-slope form of a line, we get:
y - g(-2) = 5(x - (-2))
We can then simplify this equation to get:
y - (-2² - 1) = 5(x + 2)
y + 3 = 5x + 10
Finally, we can move all of the terms containing x to one side of the equation and all of the constant terms to the other side of the equation to get the standard form of the equation of the line:
y = 5x + 7
Therefore, an equation of the secant line containing the points (-2, g(-2)) and (6, g(6)) is y = 5x + 7.

Upper Bound = 72.41
The one-sided 99% Confidence Interval for mu when n = 86 and X_Bar =71 is calculated by using the standard normal distribution table to find the critical value of 2.576, and then using the formula Upper Bound = X_Bar + (critical value * standard deviation/sqrt(n)) to calculate the upper bound of the interval. The result is an upper bound of 72.41.

on a field trip, there are `3` chaperones for every `20` students. there are `92` total people on the trip.
There are 12 chaperones in total.
In molecular biology, molecular chaperones are proteins that help big proteins or macromolecular protein complexes fold or unfold conformationally. There are different groups of molecular chaperones, all of which have the same purpose: to help big proteins fold properly during or after synthesis as well as following partial denaturation. Protein translocation for proteolysis involves chaperones as well.
The first molecular chaperones to be identified are an assembly-type of chaperones that help nucleosomes form from folded histones and DNA.
Since heat stress increases the propensity for protein aggregation, one of the main roles of molecular chaperones is to prevent the accumulation of misfolded proteins. As a result, many chaperone proteins are categorized as heat shock proteins.
Chaperones and students combined: 3 + 20 = 23
by the number of individuals in total:
92 / 23 = 4
Divide that sum by the proportional number of chaperones:
4 x 3 = 12
There are 12 chaperones in total.

The slope of a line is -6. The line goes through the point (7.-14). Write the equation of the line in point-slope form.
Answer:
Step-by-step explanation:
(7, -14)
y - y1 = m(x - x1)
y - (-14) = -6(x - 7) = y + 14 = -6(x - 7)
Standard Form
y + 14 = -6x + 42
y = -6x + 28
Which expression is equivalent to the following complex fraction?
(1 - 1/x)/2
Equivalent expression is (x-1)/2x for ((1 -1/x)/2), So Option 1 is correct.
If two expressions can be written similarly or can be combined into a single, simpler phrase, then those two expressions are comparable. Additionally, you can tell if two expressions are equal if you substitute values for the variable in both and they get the same result. The numerator and denominator of equivalent fractions can be written by multiplying or dividing them both by the same value.
This is the rationale for why these fractions simplify to the same number. Equivalent ratios are two ratios that have identical values. Divide or multiply both amounts by the same number to arrive at an equivalent ratio. The method is the same as determining equivalent fractions.
Here expression is ((1 -1/x)/2)
take x as lcm then (x-1)/2x
correct option is (A).

Josh had a major growth spurt during middle school. Two years ago, when Josh was 2/3 as tall as he is
now, he was 4½ feet tall. How tall is Josh now?
a. Let h = Josh's current height. What equation can be written to solve for h?
b. Solve the equation, showing your work. Express his current height as a mixed number.
The fraction of Josh's height which is 2/3 of Josh's current height indicates that the equation that can be used to find Josh's height and Josh's current height are;
a. (2/3) × h 4 1/2 feet
b. 6 3/4 feet
What is a fraction?A fraction of an item is a representation of the whole or entire of the item.
Josh's height two years ago = (2/3) × Josh's height now
Hosh's height two years ago = 4 1/2 feet
a. Josh's current height, = h
An equation is mathematical statement that joins two equivalent expressions with an equal to sign.
(2/3) of Josh's current height is equivalent to Josh's initial height of 4 1/2 feet.
The equation that can be written to solve for h is therefore;
(2/3) × h = 4 1/2b. h = (4 1/2)/(2/3) = (4 1/2) × 3/2
4 1/2 = 9/2
Therefore;
h = 9/2 × 3/2 = 27/4 = 6 3/4
Josh's current height, h = 6 3/4 feet

Suppose that two high school students decide to see if they get the same results as the researcher. They both do the puzzle while in the presence of the pleasant floral scent. The mean of their times is m = 80.2 seconds, the same as that of the researcher. It is appropriate to conclude which of the following? A) They have reproduced the results of the researcher and their P-value will be the same as that of the researcher.B) They have reproduced the results of the researcher, but their P-value will be slightly smaller than that of the researcher.C) They will reach the same statistical conclusion as the researcher, but their P-value will be slightly different than that of the researcher.D) None of the above
The mean of their times is x = 80.2 seconds, the same as that of the researcher, after analyzing the given data we conclude that none of the given condition is appropriate.
We can observe that the researcher wishes to put the theories to the test.
H0: = 80.2 = null hypothesis
Ha: > 80.2 = alternative hypothesis.
The population mean is 80.2 and the standard deviation is 4.
