We are required to find the number of tons of fertilizer are on each acre

The tons of fertilizer are on each acre of land is 1 47/52 tons

Given:

Total tons of fertilizer Alicia has = 4⅛ tons

Total acres of land = 2¹/6 acres

Tons of fertilizer on each acre of land = Total tons of fertilizer Alicia has ÷ Total acres of land

= 4 1/8 ÷ 2 1/6

= 33/8 ÷ 13/6

= 33/8 × 6/13

= (33 × 6) / (8 × 13)

= 198 / 104

= 1 94/104

= 1 47/52

Therefore, the tons of fertilizer are on each acre of land is 1 47/52 tons

Answer:

The variable y should equal 5 2/5 or 5.4 as a decimal.

Step-by-step explanation:

The variable x equals 1 so we can replace x in the equation y = 2/5x + 5 with 1.

y = 2/5(1) + 5

This is our new equation. Any number multiplied by 1 will equal itself so in this case, 2/5 times 1 equals 2/5 or 0.4 in decimal form. Now we can add 2/5 or 0.4 to 5 and we will get 5 2/5 or 5.4. Now we will only have y =  5 2/5 or 5/4 in the equation and this is where we will stop solving for y. In conclusion, y equals 5 2/5 or 5.4. I hope this helps! If this answer is wrong, please give me some feedback on what I did wrong! Thank you!

We assume that the population standard deviation are known, the samples from each population are independent, the population is normally distributed if we use t test of two samples.

Given T test of significance has been used.

T test is a statistical test that is like z test. Z test is used when n>30 and t test is used when n<30. It is used in hypothesis testing.

We know that there are many test which can be used to test a hypothesis.

The requirements to perform a two sample t procedure are as follows:

1)The two samples have equal variance. Hence the variance should be known.

2) The samples for which the two sample t procedure is performed must be independent.

3) The data are in alignment with the normal distribution probability.

4) The sample are random samples taken from different respective population.

Hence when two sample t procedure is performed we have to assume population standard deviation is known and population is normally distributed.

Answer:

The last one, (-6,9)

Step-by-step explanation: For it to be right the nine would have to be negative.

Answer:

I think it's the last one(-6,9) or the third one(6,-1)

Step-by-step explanation:

Answer:

I think the total number of combinations of 3 from 6 = 6C3 = 20

All possible combinations of 3 which have a product divisible by 3 must contain either a 3 or a 6.

So the number not divisible must be 3 combinations from the number 1, 2, 4, and 5.= which is 4

So the required probability is 20-4 ? 20 = 16/20 = 0.8 Answer

The growth constant k is approximately 0.2310.

To find the growth constant k, we can use the information that the population has a doubling time of 3 hours.

In the exponential growth model, the doubling time is the time it takes for the population to double in size.

Let's set up an equation to solve for k:

2Po = Po * e^(k * 3)

Here, 2Po represents double the initial population, and Po * e^(k * 3) represents the population after 3 hours of exponential growth.

Dividing both sides of the equation by Po:

2 = e^(k * 3)

To solve for k, we take the natural logarithm (ln) of both sides:

ln(2) = ln(e^(k * 3))

Using the property of logarithms (ln(a^b) = b * ln(a)):

ln(2) = k * 3 * ln(e)

Since ln(e) is equal to 1:

ln(2) = k * 3

Now we can solve for k:

k = ln(2) / 3

Using a calculator, we find that k ≈ 0.2310.

Therefore, the growth constant k is approximately 0.2310.

Answer:

m∠C = 102°

Step-by-step explanation:

This is a quadrilateral inscribed in a circle

The sum of opposite angles in a cyclic quadrilateral is equal to 180°

m∠D + m∠B = 180°

m∠B = 180° - m∠D

m∠B = 180° - 80°

m∠B = 100°

We know what m∠B

We have external angles outside the circle.

m∠CDA is opposite m∠B

m∠CDA = 2 × m∠B

m∠CDA = 2 × 100°

m∠CDA = 200°

m∠CDA is the sum of m∠CD and m∠DA

m∠CDA = m∠CD + m∠DA

m∠DA = m∠CDA - m∠CD

m∠DA = 200° - 116°

m∠DA = 84°

m∠DAB is an exterior angle also, hence,

m∠DAB is the sum of m∠DA and m∠AB

m∠DAB = m∠DA + m∠AB

m∠DAB = 84° + 120°

m∠DAB = 204°

Finally we can solve for m∠C

m∠DAB is Opposite m∠C

So, m∠C = 1/2 × m∠DAB

m∠C = 1/2 × 204

m∠C = 102°

The standard deviation of the salaries for the company's 80 employees is calculated to be X, where X represents the numerical value of the standard deviation.

The standard deviation measures the dispersion or variability of a set of data points. In order to calculate the standard deviation, we need to first find the mean (average) of the salaries. Then, for each salary, we calculate the difference between the salary and the mean, square that difference, and sum up all the squared differences. Next, we divide the sum by the total number of salaries (80 in this case) minus 1 to obtain the variance. Finally, the standard deviation is obtained by taking the square root of the variance. This accounts for the fact that the squared differences are in squared units, while the standard deviation should be in the original units (currency in this case).

By following this process, we can find the standard deviation of the salaries for the 80 employees in the company. This value represents the measure of variability or spread in the salary distribution, providing insights into how salaries deviate from the mean.

False. An n × n matrix that is orthogonally diagonalizable does not necessarily have to be symmetric. A matrix is said to be orthogonally diagonalizable if it can be expressed as PDP^T, where P is an orthogonal matrix and D is a diagonal matrix.

For a matrix to be symmetric, it must satisfy the condition A = A^T, where A^T denotes the transpose of A. While it is true that symmetric matrices are always orthogonally diagonalizable, the converse is not necessarily true. There exist non-symmetric matrices that can still be orthogonally diagonalized. An example of such a matrix is the following:

  [1  2]

A = [3 4]

This matrix is not symmetric, as A^T is:

  [1  3]

A^T = [2 4]

However, it is still orthogonally diagonalizable. The matrix A can be diagonalized as:

A = PDP^T, where P = [0.8507 -0.5257]

[0.5257 0.8507]

          and D = [-0.3723   0     ]

                    [ 0      5.3723]

Therefore, it is not necessary for an n × n matrix that is orthogonally diagonalizable to be symmetric.

Step-by-step explanation:

A function is given to us and we need to tell which graph represents the given function. The function given to us is,

\(\tt: \implies f(x) = -( x + 3 )( x + 1 ) \)

Let's find out at which points do the graph Intersects x axis / finding the roots. For that substitute f(x) = 0 , we have ,

1. Independent random samples arise when one random sample is split into groups differing by an observed feature is incorrect.

2. The margin of error of a confidence interval about the difference between the means of two populations is equal to half the width of the confidence interval.

1. Independent random samples arise when individuals in a sample are randomly assigned to experimental groups, data is recorded repeatedly on a random sample of individuals, or random samples are selected separately. The statement that one random sample is split into groups differing by an observed feature does not accurately describe independent random samples.

2. The margin of error in a confidence interval represents the range of values within which the true population parameter is likely to fall. It is calculated by taking half of the width of the confidence interval. Therefore, the correct answer is that the margin of error is equal to half the width of the confidence interval.

In summary, the incorrect statement is that independent random samples arise when one random sample is split into groups differing by an observed feature. The margin of error of a confidence interval about the difference between the means of two populations is equal to half the width of the confidence interval.

To simplify the expression -p/3 + q/3 - 2p/3 - q, we can combine like terms.  the simplified form of the expression -p/3 + q/3 - 2p/3 - q is (-4p - 2q)/3.

By adding or subtracting the coefficients of the variables, we can simplify the expression to its simplest form.

The expression -p/3 + q/3 - 2p/3 - q can be simplified by combining like terms. The simplified form of the expression is (-4p - 2q)/3.

Given the expression: -p/3 + q/3 - 2p/3 - q

We can group the like terms together:

(-p - 2p)/3 + (q - q)/3

Simplifying each group separately:

-3p/3 - 2q/3

Since -3p/3 is equivalent to -p, and -2q/3 remains the same, the expression can be further simplified to:

(-p - 2q)/3

Therefore, the simplified form of the expression -p/3 + q/3 - 2p/3 - q is (-4p - 2q)/3.
