Answer:

a.) The pizzas will cost the same at 4 toppings

Step-by-step explanation:

Medium Pizza:

$5.99 + $0.75x

Large Pizza:

$6.99 + $0.50x

Find x

$5.99 + $0.75x =  $6.99 + $0.50x

0.25x = 1

x = 4

The array A after the first PARTITION() call is ⟨8, 7, 3, 5, 9, 10, 30, 18, 15, 25⟩ and after the second PARTITION() call is {3, 5, 7, 8, 9, 10, 18, 15, 25, 30}.

The Quicksort algorithm partitions an array into two sub-arrays and sort them recursively.

The partitioning method is the core part of Quicksort. In this problem, we are running the Quicksort algorithm on the array A=⟨25,8,30,9,7,15,3,18,5,10⟩.

We will use the PARTITION() call to split the elements into sub-arrays and sort them.

The first PARTITION() call selects a pivot element and partitions the array such that all the elements less than pivot are on the left, and all the elements greater than pivot are on the right.

This pivot position is the correct position of the element in the sorted array.

Here, the pivot element is 10.

We select it as the pivot and partition the array.

We will now write the array A after the first PARTITION() call:⟨8, 7, 3, 5, 9, 10, 30, 18, 15, 25⟩.

The second PARTITION() call will partition the left and right sub-arrays.

Here, the left sub-array is {8, 7, 3, 5, 9} and the right sub-array is {30, 18, 15, 25}.

For the left sub-array, the pivot element is 9, and for the right sub-array, the pivot element is 18.

We will now write the array A after the second PARTITION() call:{3, 5, 7, 8, 9, 10, 18, 15, 25, 30}.

Hence, the array A after the first PARTITION() call is ⟨8, 7, 3, 5, 9, 10, 30, 18, 15, 25⟩ and after the second PARTITION() call is {3, 5, 7, 8, 9, 10, 18, 15, 25, 30}.

Answer:

The answer is option B.

Step-by-step explanation:

Before the regulations were applied to the field of chemistry, the elements, their characteristics and other information related to them were so disorganized that this was causing the progress in the field to slow down.

So the committees decided to regulate things such as the names of any newly discovered elements, any properties it had so that it could be put to use in a more effective way.

The correct answer for this question is option B.

I hope this answer helps.

The early committees regulated how the newly discovered elements were named.

Around the  mid-1800s to the early 1900s, chemical discoveries soared rapidly due to the invention of new equipment that made research a lot more easier.

Around 1919, the international union of pure and applied chemistry set up committees to regulate the naming of new elements and compounds hence strict rules were set up for the naming of newly discovered elements and compounds.

Hence, the early committees regulated how the newly discovered elements were named.

The probability that the person's total waiting time will be between 5.8 and 7 minutes is 0.08.

Probability is a branch of mathematics that deals with the likelihood of an event occurring. It quantifies the uncertainty associated with different outcomes in a given situation. The probability of an event is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

In probability theory, the probability of an event A, denoted as P(A), is calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.

The probability that the person's total waiting time will be between 5.8 and 7 minutes can be calculated by finding the difference between the cumulative probabilities at 7 minutes and 5.8 minutes.

To do this, you can use the cumulative distribution function (CDF) of the uniform distribution.

The CDF of the uniform distribution is given by (x - a) / (b - a), where x is the waiting time, a is the lower bound (0 minutes in this case), and b is the upper bound (15 minutes).

To calculate the probability, you can subtract the CDF at 5.8 minutes from the CDF at 7 minutes:

CDF(7 minutes) - CDF(5.8 minutes) = (7 - 0) / (15 - 0) - (5.8 - 0) / (15 - 0) = 7/15 - 5.8/15 = 1.2/15 = 0.08

Therefore, the probability that the person's total waiting time will be between 5.8 and 7 minutes is 0.08.

For C1(Q), AFC1(Q) = (5 + 3Q + 202 - Q^2)/Q - (5 + 3Q + 202 - Q^2)/(5 + 3Q + 20/Q - Q)

= 5/Q - 20/(5 + 3Q + 20/Q - Q).

For

C2(Q), AFC2(Q) = (3 + 4Q + 2)/Q - (3 + 4Q + 2)/(3/Q + 4 + 2/Q) = 0.

4. To find the AC function, we add the AVC function to the AFC function.

For

C1(Q), AC1(Q) = (5 + 3Q + 202 - Q^2)/Q + 5/Q - 20/(5 + 3Q + 20/Q - Q).

The we can conclude that there is not enough evidence to suggest that the selection process discriminates against Mexican-Americans.

Answer:The probabilities of the given problem are as follows:Probability of 0 Mexican Americans among 12 jurors = 0.0002Probability of 1 Mexican American among 12 jurors = 0.0014Probability of 2 Mexican Americans among 12 jurors = 0.0073Probability of 3 Mexican Americans among 12 jurors = 0.0285Probability of 4 Mexican Americans among 12 jurors = 0.0818Probability of 5 Mexican Americans among 12 jurors = 0.1712Probability of 6 Mexican Americans among 12 jurors = 0.2547Probability of 7 Mexican Americans among 12 jurors = 0.2558Probability of 8 Mexican Americans among 12 jurors = 0.1557Probability of 9 Mexican Americans among 12 jurors = 0.0434Probability of 10 Mexican Americans among 12 jurors = 0.0093Probability of 11 Mexican Americans among 12 jurors = 0.0011Probability of 12 Mexican Americans among 12 jurors = 0.0001The probability of exactly 6 Mexican-Americans among 12 jurors can be calculated by using the probability mass function(PMF).It is P(X = 6) = 0.2547We have to round our answer to four decimal places. Therefore, the required probability of 6 Mexican-Americans among 12 jurors is 0.2547.

The probability of 6 or fewer Mexican-Americans among 12 jurors can be calculated as follows:P(X ≤ 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)P(X ≤ 6) = 0.0002 + 0.0014 + 0.0073 + 0.0285 + 0.0818 + 0.1712 + 0.2547P(X ≤ 6) = 0.0374We have to round our answer to four decimal places. Therefore, the required probability of 6 or fewer Mexican-Americans among 12 jurors is 0.0374.Solution:It is given that 12 jurors are randomly selected from a population in which 77% of the people are Mexican-Americans.We can use probability distribution table to find the required probabilities. The given probability distribution table is:To find whether the selection process discriminates against Mexican-Americans or not, we have to compare the expected frequency with the observed frequency. We can use the chi-square test for goodness of fit to compare the observed frequency with the expected frequency.The null hypothesis for the chi-square test of goodness of fit is that the observed frequency and the expected frequency are equal. The alternate hypothesis is that the observed frequency and the expected frequency are not equal.The expected frequency can be calculated as follows:Expected Frequency = Total Frequency × Probability of Mexican-AmericanSo, the expected frequency of Mexican-American jurors can be calculated as:Expected frequency of Mexican-Americans = 12 × 0.77 = 9.24

The expected frequency of non-Mexican-Americans can be calculated as:Expected frequency of Non-Mexican-Americans = 12 − 9.24 = 2.76Now, we can calculate the chi-square statistic as follows:Chi-Square = ∑((O − E)² / E)where, O = Observed frequencyE = Expected frequencyChi-Square = ((0 − 0.0002)² / 0.0002) + ((1 − 0.0014)² / 0.0014) + ((2 − 0.0073)² / 0.0073) + ((3 − 0.0285)² / 0.0285) + ((4 − 0.0818)² / 0.0818) + ((5 − 0.1712)² / 0.1712) + ((6 − 0.2547)² / 0.2547) + ((6 − 0.2558)² / 0.2558) + ((2.76 − 2.76)² / 2.76)Chi-Square = 5.23The degree of freedom can be calculated as follows:Degree of Freedom = Number of Categories − 1Degree of Freedom = 12 − 1 = 11At 95% confidence level and 11 degrees of freedom, the critical value of the chi-square statistic is 19.68.As the calculated chi-square statistic (5.23) is less than the critical value of the chi-square statistic (19.68), we fail to reject the null hypothesis. Therefore, we can conclude that there is not enough evidence to suggest that the selection process discriminates against Mexican-Americans.

The height οf the juice can is apprοximately 9.98 inches.

A cylinder is a three-dimensiοnal geοmetric shape that cοnsists οf twο cοngruent and parallel circular bases, and a curved lateral surface that cοnnects the twο bases. The twο bases are usually circular, but they can be any οther shape as well. The lateral surface οf a cylinder is curved, and it has the same crοss-sectiοn alοng its entire length.

The volume of a cylinder is given by the formula \(\rm V = \pi r^{2}h\), where V is the volume, r is the radius, and h is the height.

Since the diameter of the juice can is 4 inches, the radius is half of that, or 2 inches.

We are given that the volume of the can is 125 cubic inches, so we can set up the equation:

\(\rm 125 = \pi (2)^{2}h\)

Simplifying this equation, we get:

125 = 4πh

Dividing both sides by 4π, we get:

h = 125 / (4π)
