The percentage of the decrease in the value of the XYZ Company stock is 16%.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
The decrease in the value of the stock is $25 - $21 = $4.
To find the percent decrease, we need to divide the decrease by the original value and then multiply by 100:
Percent decrease = (Decrease / Original value) x 100
In this case, the original value is $25, so:
Percent decrease = (4 / 25) x 100 = 16%
Therefore, the percentage of the decrease in the value of the XYZ Company stock is 16%.

Answer:
Step-by-step explanation:
A market research company was interested in comparing three communities A, B and C to determine whether there are any differences in their use of water filters in homes. Each of 100 homeowners sampled from each community was asked whether or not they have installed water-filtering system in their homes. Their responses (Yes or No) are summarized in the following contingency table.
Use Filters
Community | Yes | No
A 62 38
B 58 42
C 73 27
a) Clearly state the null and alternative hypotheses in this problem.
b) Calculate the expected count for the bottom right cell (i.e., Community ‘C’ and ’No’), and explain what the number means.
c) The Chi-square statistic has been calculated to be 13.22. What can we conclude from this finding?
a) The null hypothesis is that there is no difference in the proportion of homeowners using water filters among the three communities. The alternative hypothesis is that at least one community has a different proportion of homeowners using water filters than the other communities.
b) To calculate the expected count for the bottom right cell, we can use the formula:
Expected count = (row total x column total) / grand total
The row total for Community C and the column total for No are both 100, and the grand total is 300. Therefore:
Expected count = (100 x 100) / 300 = 33.33
The expected count of 33.33 for the bottom right cell means that if there were no difference in the proportions of homeowners using water filters among the three communities, we would expect 33.33 of the 100 homeowners in Community C to answer 'No' to the question about water filters.
c) To determine what we can conclude from the Chi-square statistic of 13.22, we need to compare it to the critical value for a Chi-square distribution with (3-1) x (2-1) = 2 degrees of freedom at the desired level of significance. Let's assume a level of significance of 0.05. From a Chi-square distribution table, the critical value with 2 degrees of freedom at 0.05 level of significance is 5.99.
Since 13.22 is greater than 5.99, we can reject the null hypothesis and conclude that there is a significant difference in the proportion of homeowners using water filters among the three communities. However, we cannot determine from this test alone which communities have different proportions of homeowners using water filters. We would need to conduct further tests, such as post-hoc tests, to investigate the specific differences among the communities.
Suppose that a farmer has 75 rods (4 rods = 1 acre) on which to plant two crops: wheat and corn. To produce these crops, it costs the farmer (for seed, water, fertilizer, etc. ) $120 per rod for the wheat, and $210 per rod for the corn. The farmer has $15,000 available for expenses, but after the harvest the farmer must store the crops while awaiting favorable or good market conditions. The farmer has storage space for 4,000 bushels. Each rod yields an average of 110 bushels of wheat or 30 bushels of corn. If the net profit per bushel of wheat (after all the expenses) is $1.30 and for corn is $2.00, how should the merry farmer plant the 75 rods to maximize profit?
Use the optimization method described in the lecture.
Difference of density per acre of wheat and corn = 105
What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
Given:
Yield in 110 acre farm = 17,600 Bushes of corn
Yield in 250 acre farm = 13,750 Bushes of wheat
Find:
Difference of density per acre of wheat and corn
Computation:
Yield per acres Bushes of corn = 17,600 / 110
Yield per acres Bushes of corn = 160
Yield per acres Bushes of wheat = 13,750 / 250
Yield per acres Bushes of wheat = 55
Difference of density per acre of wheat and corn = Yield per acres Bushes of corn - Yield per acres Bushes of wheat
Difference of density per acre of wheat and corn = 160 - 55
Difference of density per acre of wheat and corn = 105

The value of s-r is 2
What is common ratio?
In a geometric sequence, ratio of each term to its immediately preceding term is always constant and is known as common ratio.
each term is equal to the sum of the two terms after it.
=> ar^n = ar^(n+1) + ar^(n+2)
On dividing both the sides by ar^n and simplfying we get
r= 0.618
sum of the series is:
s= a/(1-r) , a=first term
=> s= 1/(1-0.618 )
=> s= 2.618
s-r = 2.618 - 0.618 = 2

Determine what number should be added to complete the square of the expression 4x^2-8x
The number that should be added to complete the square of the expression 4x² - 8x is 1.
What is an expression?
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
To complete the square of the expression 4x² - 8x, add a constant term that will make it a perfect square trinomial.
First, factor out the coefficient of the x² term -
4x² - 8x = 4(x² - 2x)
Next, add a constant term that will make the expression inside the parentheses a perfect square.
To do this, take half of the coefficient of the x term and square it.
Half of -2 is -1, and (-1)^2 is 1.
So add 1 to the expression inside the parentheses to make it a perfect square -
4x² - 8x + 1 = 4(x² - 2x + 1)
Simplify this expression by factoring the trinomial inside the parentheses -
4x² - 8x + 1 = 4(x - 1)²
Therefore, the number is 1.

The volume of each tile is 134 cm³.
Describe Volume of Cuboid?The volume of a cuboid is the amount of space it occupies in three-dimensional space. A cuboid is a three-dimensional geometric shape with six rectangular faces, where each face has perpendicular edges to two other adjacent faces. The formula for calculating the volume of a cuboid is V = l x w x h, where V is the volume, l is the length of the cuboid, w is the width of the cuboid, and h is the height of the cuboid.
To calculate the volume of a cuboid, first measure its length, width, and height. Then, multiply the length by the width and the height, and then multiply the result by the height again. This gives the volume of the cuboid in cubic units, such as cubic inches, cubic centimeters, or cubic meters.
For example, if a cuboid has a length of 5 cm, a width of 3 cm, and a height of 2 cm, the volume can be calculated as follows:
V = l x w x h
V = 5 cm x 3 cm x 2 cm
V = 30 cubic centimeters
Therefore, the volume of the cuboid is 30 cubic centimeters.
The volume of each tile can be calculated by multiplying its length, width, and height:
Volume = 10 cm × 20 cm × 0.67 cm = 134 cm³
Therefore, the volume of each tile is 134 cm³.

Previous question
The limit of each function at the given point i n the question 10 to 14, is explained below.
Limit Of A function:A function may get close to two distinct limits. There are two scenarios: one in which the variable approaches its limit by values larger than the limit, and the other by values smaller than the limit. Although the right- and left-hand limits are present in this scenario, the limit is not defined.
When a variable approaches its limit from the right, the function's right-hand limit is the value that approaches.a
10). The limit of f(z) = Arg z as z approaches Zo = 1 does not exist. This is because the argument function is not continuous at the point z = 1, where there is a branch cut.
11). The limit of f(z) = [tex](1 - lm z)^{-1}[/tex] as z approaches z0 = -8 does not exist. This is because the function approaches infinity as z approaches -8 from the left, and negative infinity as z approaches -8 from the right.
However, if we consider the limit of f(z) as z approaches z0 = -8 + i from both the left and the right, the limit exists and is equal to 0. This is because in the complex plane, the value of Im z cannot exceed 1, so as z approaches -8 + i, the denominator (1 - Im z) approaches 0, and the function approaches infinity. However, the numerator approaches a finite value of 1, which cancels out the denominator, and the overall limit is equal to 0.
12). The limit of f(z) = (z - 2) log(z - 2) as z approaches z0 = 2 is 0. This is because the term (z - 2) approaches 0 as z approaches 2, and log(z - 2) approaches 0 as well because log(z - 2) is continuous at z = 2. Therefore, the limit is equal to 0.
13). The limit of f(z) = -1/z as z approaches z0 = 0 does not exist. This is because as z approaches 0, the magnitude of 1/z approaches infinity, but the direction of approach depends on which quadrant the limit is approached from. Since the limit does not approach a unique value from all directions, the limit does not exist.
14). The limit of f(z) = 2 + [tex]2^{1/z}[/tex] as z approaches infinity does not exist. This is because as z approaches infinity, the term [tex]2^{1/z}[/tex] approaches 1, and the limit approaches 2 + 1 = 3. However, if we approach infinity along the real axis, the limit of [tex]2^{1/z}[/tex] approaches 1, but if we approach infinity along the imaginary axis, the limit of [tex]2^{1/z}[/tex] approaches infinity. Therefore, the limit of f(z) does not exist.

The height of the triangle is h = 2A/6.
What is height?Height is the measure of vertical distance, either how "tall" something or someone is, or how "high" the point is. For example, a person's height is typically measured using a stadiometer and is recorded in centimeters or feet and inches. The height of a mountain is usually measured in meters or feet. In aviation, height is measured from the surface of the earth, either above ground level (AGL) or above mean sea level (AMSL).
To find the height of a right triangle given the base, we can use the area formula A = 1/2bh. Rearranging this equation gives us the height: h = 2A/b. In this case, the base is 6 inches and the area is given as A. Therefore, the height of the triangle is h = 2A/6.

1) The eighth grade class has 20% fewer students this year than they
had as seventh graders. Write an expression to show the decline in
class numbers, and then simplify the expression. Use (s) to represent
the number of seventh grade students.
Answer:
Step-by-step explanation:
To represent the number of eighth-grade students, we can use the expression:
0.8s
This is because the problem states that there are 20% fewer students in the eighth grade than in the seventh grade, which means that the number of eighth-grade students is equal to 80% of the number of seventh-grade students.
To simplify this expression, we can use the distributive property:
0.8s = 1s - 0.2s
This shows that the number of eighth-grade students is equal to the number of seventh-grade students minus 20% of the number of seventh-grade students. We can further simplify this to:
0.8s = 0.8s
This means that the number of eighth-grade students is equal to 80% of the number of seventh-grade students, which is consistent with the original problem statement.
