10 Explain why it is less appropriate to express the area of the property cultivated by the agricultural cooperative in m²?
It is less appropriate to express the area of the property cultivated by the agricultural cooperative in m² because this unit of measurement is too small for such a large area.
The area of a property cultivated by an agricultural cooperative is typically very large, often spanning several hectares or even square kilometers. Expressing the area in m² would result in a very large number that is difficult to comprehend and work with. It is more appropriate to use a larger unit of measurement, such as hectares or square kilometers, to express the area of the property cultivated by the agricultural cooperative. This allows for a more concise and understandable representation of the area.

Five students took a quiz. The lowest score was 4, the highest score was 6, the average (mean) was 5.2, and the mode was 6. A possible set of scores for the students is:
A possible set of scores for the students is: 4, 4, 6, 6, 6
How to solve the measures of Central Tendencies?We are given that five students took the quiz. If the lowest score is 4 and the highest score is 6, we can say that the set of values can be expressed as:
4, x, y, z, 6
Here we can see that the mode is 6 and the mean is 5.2. Therefore, at least one other student of hers has scored her 6, which could result in:
4, x, y, 6, 6
Therefore:
(4 + x + y + 6 + 6)/5 = 5.2
16+x+y=26
x + y = 10
So the other two numbers are probably 6 and 4, because 6 is the mode, so they can't both be 5.

For the given inequality 14 - 3f > 2 the option that comes out be correct is
f < 4 i.e option 2.
What is inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.The majority of the time, size comparisons between two numbers on the number line are made.
Here, "Less than" and "Greater than" have new meanings.
Less-than sign is the symbol for such phrase.
14 - 3f > 2
adding 3f on both sides:
14 - 3f + 3f > 2 + 3f
14 > 2 + 3f
subtracting 2 on both sides:
14 - 2 > 2 + 3f - 2
12 > 3f
dividing 3 on both sides:
(12)/3 > (3f)/3
4 > f
which means f < 4
Therefore, option 2 is correct.

All sample respondents must do so independently, meaning they are not coerced into responding D. Non-response must be kept to a minimum E. None of the above
The independence assumption says that all sample respondents must do so independently, meaning they are not coerced into responding. Thus, option C is the right answer.
What is the independence assumption? The independence assumption is a term used in statistical surveys that refers to the idea that survey participants' responses are not influenced by each other. As a result, data is seen as independent because it is not influenced by any other data in the same sample. This assumption is critical since it aids in the development of statistical analysis, which is used to understand how variables relate to one another. A, B, D, and E options are not correct because:
A. Each sample needs to have a sample size of 30 or more. This is not correct because it's a condition used in the Central Limit Theorem.
B. All observations have to be drawn from the same distribution: This is not correct because the assumptions depend on the study.
C. All sample respondents must do so independently, meaning they are not coerced into responding: This is the right option because the independence assumption says that all sample respondents must do so independently, meaning they are not coerced into responding.
D. Non-response must be kept to a minimum. This is not correct because it is about survey sample bias, not independence.
E. None of the above: This is not the right answer because option C is the right answer.

of all rectangles with area 121, which has the minimum perimeter?
Let P and w be the perimeter and width respectively, of the rectangle. Wite the objective function in terms of P and w Assume that the width is less than the length the dimensions are unequal P=__ (Type an expression) The interval of interest of the objective function is __
(Simplify your answer Type your answer in interval notation) Of all rectangles with area 121, the one with dimensions has the minimum perimeter __
(Simplify your answers Use a comma to separate answers as needed)
Therefore, the rectangle with dimensions 11 and 11 (width and length, respectively) has the minimum perimeter.
Let's denote the length of the rectangle as L. Since the area of the rectangle is given as 121, we have the equation L * w = 121.
We are looking for the rectangle with the minimum perimeter. The perimeter P can be calculated as 2L + 2w.
To write the objective function in terms of P and w, we substitute L from the area equation:
2L + 2w = 2(121/w) + 2w
Simplifying, we get:
P = 242/w + 2w
The interval of interest for the objective function P is the range of valid values for w. Since the width is less than the length, we can assume that w > 0. Also, from the area equation, we have L * w = 121, so w = 121/L. Since w > 0, L must be greater than 0. Therefore, the interval of interest is (0, ∞), meaning the width can take any positive value.
To find the dimensions that result in the minimum perimeter, we need to minimize the objective function P. Taking the derivative of P with respect to w and setting it to zero will give us the critical points. Let's differentiate:
dP/dw = -242/w^2 + 2
Setting dP/dw to zero:
-242/w^2 + 2 = 0
242/w^2 = 2
w^2 = 242/2
w^2 = 121
w = 11
Since the width cannot be negative, we discard the negative solution. Thus, the width w = 11.
Substituting this value back into the area equation, we can find the length L:
L * 11 = 121
L = 121/11
L = 11

Two teachers, Mrs. Wright and Mr. Kinder, decide to buy calculators and protractors for their classrooms. Mrs.
Wright buys 40 calculators and 30 protractors for $485. Mr.
Kinder buys 20 of each for $252. What are the individual costs of the calculators and protractors that were purchased?
In response to the question, we may say that Therefore, the cost of a equation calculator is $10.7 and the cost of a protractor is $1.9.
Let the cost of one calculator be c and the cost of one protractor be p. Then we can write two equations based on the information given:
40c + 30p = 485 (Equation 1)
20c + 20p = 252 (Equation 2)
We can simplify Equation 2 by dividing both sides by 20:
c + p = 12.6 (Simplified Equation 2)
Now we can solve this system of equations using substitution. Solving Equation 2 for c, we get:
c = 12.6 - p
Substituting this expression for c into Equation 1, we get:
40(12.6 - p) + 30p = 485
Expanding and simplifying:
504 - 40p + 30p = 485
Solving for p:
-10p = -19
p = 1.9
Substituting this value for p into Simplified Equation 2, we get:
c + 1.9 = 12.6
Solving for c:
c = 10.7
Therefore, the cost of one calculator is $10.7 and the cost of one protractor is $1.9.

cos^2x sin^4x lowering powers
The simplified expression of cos^2x sin^4x is cos^2x - 2cos^4x + cos^6x.
The expression cos^2x sin^4x can be simplified by using the trigonometric identity that states sin^2x + cos^2x = 1.
We can rewrite cos^2x sin^4x as cos^2x (sin^2x)^2. Then, using the trigonometric identity sin^2x + cos^2x = 1, we can substitute (1 - cos^2x) for sin^2x.
This gives us cos^2x (1 - cos^2x)^2, which can be expanded using the binomial theorem to give cos^2x (1 - 2cos^2x + cos^4x).
Finally, we can simplify this expression further by distributing the cos^2x term and collecting like terms to get cos^2x - 2cos^4x + cos^6x.
Therefore, the simplified expression of cos^2x sin^4x is cos^2x - 2cos^4x + cos^6x.

When Tracey pours all the water from the smaller 5-inch cube container into the larger 7-inch cube container, the water will be approximately 7 inches deep in the larger container.
To find out how deep the water will be in the larger container, we need to consider the volume of water transferred from the smaller container. Since both containers are cube-shaped, the volume of each container is equal to the length of one side cubed.
The volume of the smaller container is 5 inches * 5 inches * 5 inches = 125 cubic inches.
When Tracey pours all the water from the smaller container into the larger container, the water completely fills the larger container. The volume of the larger container is 7 inches * 7 inches * 7 inches = 343 cubic inches.
Since the water fills the larger container completely, the depth of the water in the larger container will be equal to the height of the larger container. Since all sides of the larger container have the same length, the height of the larger container is 7 inches.
Therefore, the water will be approximately 7 inches deep in the larger container.

assume that the average sat score of first year ucf students is 1175 with a standard deviation of 120 and that the distribution of their sat scores is bell-shaped symmetric. find the minimum score of top 2.5% students.
To find the minimum score of the top 2.5% of students, we need to calculate the z-score corresponding to the 97.5th percentile and then convert it back to the original SAT score scale.
First, let's calculate the z-score using the formula:
z = (x - μ) / σ
where x is the SAT score, μ is the mean (1175), and σ is the standard deviation (120).
To find the z-score corresponding to the 97.5th percentile, we need to find the z-score value that leaves 2.5% in the tail of the distribution (to the right).
Using a standard normal distribution table or a statistical calculator, we find that the z-score corresponding to the 97.5th percentile is approximately 1.96.
Now we can solve for x (the SAT score) in the z-score formula:
1.96 = (x - 1175) / 120
Multiply both sides by 120:
1.96 * 120 = x - 1175
235.2 = x - 1175
Add 1175 to both sides:
235.2 + 1175 = x
1410.2 = x
Therefore, the minimum score of the top 2.5% of students is approximately 1410.
