Answer:

$12.50

Step-by-step explanation:

18 - 12 = 6

Brandon bought 6 less than Lance and payed $75 dollars shoes.

That means that 6 shirts cost $75.

We need to divide 6 from 75

75/6 = 12.5

So each shirt costs $12.50.

Step-by-step explanation:

The probability distribution for the random variables X (number of pages with moderate graphics) and Y (number of pages with high graphics) can be represented as follows:

P(X = x, Y = y) = (30Cx * 10Cy) / (100C4)

In this scenario, we have a hypergeometric distribution because we are sampling without replacement from a finite population (100 pages).

The probability of selecting x pages with moderate graphics (out of 30) and y pages with high graphics (out of 10) from the sample can be calculated using the hypergeometric probability formula. The numerator represents the number of favorable outcomes (combinations of selecting x moderate pages and y high pages) and the denominator represents the total number of possible outcomes (combinations of selecting any 4 pages).

Using the combination formula, 30Cx represents the number of ways to choose x out of 30 moderate pages, and 10Cy represents the number of ways to choose y out of 10 high pages. The denominator, 100C4, represents the total number of ways to choose any 4 pages out of 100.

The probability distribution can be used to calculate the probabilities of different combinations of moderate and high graphics pages occurring in a sample of four pages selected from the small-business website. This information can be helpful in understanding the likelihood of certain graphics content being present in the sample and can aid in decision-making or analysis related to the website's content.

Therefore, the percent increase in iron is 50%.

To calculate the percent increase in iron, we need to find the difference between the new and old iron content, divide it by the old iron content, and then multiply by 100 to get the percentage.

Old iron content: 1.2 mg

New iron content: 1.8 mg

Difference = New iron content - Old iron content

= 1.8 mg - 1.2 mg

= 0.6 mg

Percent increase = (Difference / Old iron content) * 100

= (0.6 mg / 1.2 mg) * 100

= 0.5 * 100

BC = 78 is parallel to the midsegment DE.

This parallel midsegment is half as long as BC, so DE = BC/2 = 78/2 = 39

-------

DF = 34 doubles to AB = 2*DF = 2*34 = 68, since the midsegment is half as the parallel side, so we just think in reverse of that process.

You can predict the size of the standard error of M for a sample size of 100 relative to a sample size of 25 because of the sampling distribution.

Suppose you compile all possibilities samples of 100 children of elementary school age in your school district; the expected value of M (when n = 100) will be equal to the expected value of M for all of the possible samples of 25 children of elementary school age in your school district.

1. All possible samples of 100 children of elementary school age in your school district; the expected value of M (when n = 100) is 11.03 the expected population mean:

E(μ) = 11.03

2. The standard error of M for this distribution of samples when n = 100 will be equal to 1.964

σ/√n = 19.64/ √100 = 1.964

3. The standard error of M for all the possible samples of 100 is twice (2 times) the standard error of M for all of the possible samples of 25.

σ/√n= 19.64/√25 = 3.928 = 2( σ/√n = 19.64/√100=1.964)

4. As both the sample has a same population with different sample size, therefore we can predict the standard error on the basis of sample observation. large sample size lower stanadrd error and vice versa.

If you were interested in how much time children spend reading on weekdays among this population of 2, 431 children, would you actually compile all possible samples of a certain size, Option: No

A scientist can use bootstrap analysis to estimate the strength of evidence that a particular node in a phylogeny exists.

Bootstrap analysis is a statistical method used to determine the reliability and robustness of phylogenetic trees' topologies. In bootstrap analysis, a series of random resampling with replacement is used to assess how well the observed data fit the phylogenetic hypothesis.

Bootstrap values range from 0 to 100 and reflect the proportion of times that a particular node or branch occurs in the bootstrap replicate trees. Bootstrap values greater than 70% are usually considered strong evidence that a particular node or branch exists in the phylogenetic tree.

Bootstrap analysis is an important tool for understanding the reliability of phylogenetic trees and the evolutionary relationships among organisms.

Dimensions of the area enclosed is l = 800 ,b = 800 and the maximum area = 6,40,000 square yards.

Given:

Liana has 3200 yards of fencing to enclose a rectangular area.

Let l and b be the length and breadth.

we know that:

perimeter of rectangle = 2(l+b)

2l + 2b = 3200

l+b = 1600

b = 1600 - l

Area of rectangle A = lb

= l*1600-l

= 1600 l - l^2

Apply derivative:

dA/dl = 1600 - 2l

1600 - 2l = 0

Answer: q = 16

Step-by-step explanation:

When given the equation 3(q - 7) = 27,  you would solve for the variable.

The variable in this equation is q, so we need to isolate the variable.

Solving process:

3(q - 7) = 27

lets distribute, due to the orders of PEMDAS.

PEMDAS stands for: Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.

3(q - 7) = 27

distributing is multiplying the number correlated outside of the parenthesis with the inside components.

3q - 21 = 27

lets add 21 to both sides

3q = 48

now lets divide by 3 (we are trying to get q by itself)

q = 16

----

To check if your solution is correct, you replace the value (16) of the variable (q) within the original equation:

3 (16 − 7) = 27

Following PEMDAS you get:

3(9) = 27

27 = 27 (meaning that the solution is correct)

The student 3's numeric grade percentage is 95.6%.

The final grade for the students is calculated based on the test scores and the class project score.

The test is worth 80% and the project is worth 20% of the grade. To calculate the final grade percentage, the individual percentages of test and project are computed, then added together.

The result cannot exceed 100%.Let us calculate the weighted test score for student 3.

There were three tests each worth 100 points. The scores of student 3 are 91, 78, and 83.

We have to add up the test scores; then divide by the total number of test points and then multiply by the weighted percentage.

The weighted test score is:(91+78+83)/300 * 80% = 76.6%

We can now calculate the percentage for the project. Student 3 received a grade of 95%.

Therefore, the percentage for the project is: 95% * 20% = 19%.

Now, we add the weighted test score to the weighted project score to find the final grade for student 3. 76.6% + 19% = 95.6%.

Therefore, The final grade of student 3 is 95.6%

The maximum profit the company can earn is $90,250 when 500,000 units of the product are sold. Therefore, to yield a maximum profit, 500,000 units must be sold.

The given quadratic equation:

y = -0.001(x - 600)² + 90represents the expected profit, in thousands of dollars, of the company where x represents the number of thousands of units of the product sold by the company. We are required to determine the number of units that must be sold to yield a maximum profit.It can be noted that the given equation is in the vertex form:

y = a(x - h)² + kwhere (h, k) are the coordinates of the vertex of the parabola, and the sign of the coefficient 'a' determines the shape of the parabola. If a > 0, the parabola opens upwards, and if a < 0, the parabola opens downwards.In the given equation, the coefficient of the squared term is -0.001 which is less than zero. Therefore, the parabola opens downwards. Hence, the vertex of the parabola will give us the maximum profit that the company can earn. Thus, we need to find the value of x that corresponds to the vertex of the parabola.To find the vertex of the parabola, we can use the formula:h = -b/2a, and k = c - b²/4a

where the quadratic equation is in the standard form of ax² + bx + c = 0

On comparing the given quadratic equation with the standard form, we get:

a = -0.001, b = 1, and c = 90Substituting these values in the formula, we have:

h = -b/2a = -1/(2 × -0.001) = 500k = c - b²/4a= 90 - (1)²/4(-0.001)= 90.25

Hence, the vertex of the parabola is (500, 90.25).

This implies that the maximum profit the company can earn is $90,250 when 500,000 units of the product are sold. Therefore, to yield a maximum profit, 500,000 units must be sold.

The chef heats the chocolate, the particles in the chocolate absorb thermal energy and their kinetic energy increases.

Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness

As the chef heats the chocolate, the particles in the chocolate absorb thermal energy and their kinetic energy increases.

This increased kinetic energy causes the particles to vibrate more vigorously and move around more freely, weakening the intermolecular forces that hold them in place.

If the temperature of the chocolate is raised high enough, the intermolecular forces are weakened to the point where the particles break free from their fixed positions and the solid chocolate begins to melt and turn into a liquid.

Hence,  the chef heats the chocolate, the particles in the chocolate absorb thermal energy and their kinetic energy increases.
