The volume in units of cubic inches is 101.63 cubic inches.

Unit conversion is a process with multiple steps involving multiplication or division by a numerical factor, particularly a conversion factor. The procedure may also demand the selection of the correct number of substantial digits and rounding. Different units of conversion are used to calculate different parameters.

We convert the units of any quantity to understand better. For example, the length of a table is measured in inches; on the other hand, the length of a garden is measured in yards to make it simple to comprehend. We cannot calculate the length of a finger in miles.

1 quart is equal to 57.75 cubic inches. So, to convert a volume of 1.75 quarts to cubic inches, we multiply by 57.75:

1.75 quarts × 57.75 cubic inches/quart = 101.63 cubic inches

Therefore, the volume of the box of ice cream in cubic inches is 101.63 cubic inches.

The substantive audit sampling technique uses a statistical sampling approach is Sampling or MUS.

Sampling is a powerful tool in auditing as it allows the auditor to make conclusions about the population without having to test all the transactions, balances or data.

Substantive audit sampling refers to the use of samples in an audit process to make conclusions about a population of transactions, balances or other data.

There are three main substantive audit sampling techniques: Stratified Sampling, Attribute Sampling and Monetary Unit Sampling.

Monetary Unit Sampling or MUS is a statistical sampling approach that focuses on the monetary value of transactions.

The auditor will select a sample of transactions and calculate the expected deviation rate.

This technique is used when the auditor is focused on testing material balances and ensuring that they are correct.

The Probability that a randomly selected student who performed in the spring play, but did not perform in the spring concert is chosen is 26/53.

Now let A be the event of the student performing in Spring play

Let B be the event of students performing i the spring concert

Now according to what we know,

n(A) = 68

n(B) = 54

n(A ∩ B) = 16

Now total no. of students will be n(A U B) = 68 + 54 - 16

= 106

We need to find the number of people who performed in the spring play and not in the concert

Hence we need to find the Probability

P(A ∩ not B)

Now we can say that (A ∩ not B) will clearly be

A - (A ∩ B) Hence we get it to be

68 - 16 = 52

Hence, P(A ∩ notB) = 52/106

The value of constant a is 2.45.

To find the value of the constant a, we need to make sure that the pdf (probability density function) is properly normalized. The pdf must satisfy the following property:

∫[a, ∞] f(x) dx = 1

In this case, we have pdf:

∫[a, ∞] (12/x^3) dx = 12∫[a, ∞] (1/x^3) dx

= 12 [-1/(2x^2)]ₐ∞

= 12 * (1/(2a^2))

= 6/ a²

Therefore, to ensure that the integral is equal to 1, we need:

6/ a² = 1

Solving for a:

a^2 = 6

a = ±√6

Since x is always positive, we have a = √6 ≈ 2.45.

Answer:

(t + 3)(7t - 2)

Step-by-step explanation:

7t² - 19t - 6

consider the factors of the product of the coefficient of the t² term and the constant term which sum to give the coefficient of the t- term

product = 7 × - 6 = - 42 and sum = - 19

the factors are 21 and - 2

use these factors to split the t- term

7t² + 21t - 2t - 6 ( factor the first/second and third/fourth terms )

7t(t + 3) - 2(t + 3) ← factor out (t + 3) from each term

The subgroups of S6 include the following abelian groups: Z₁, Z₂, Z₃, Z₆, Z₂ x Z₂, and Z₃ x Z₂

A subgroup of a group is isomorphic to another group if there is a bijective homomorphism between the two groups, meaning there is a one-to-one correspondence between their elements that preserves the group operation. In this case, the subgroup of S6 (the symmetric group on 6 elements) is isomorphic to one of the abelian groups.

It is known that the number of subgroups of a finite group is bounded above by the number of its elements, so there are only finitely many possible subgroups of S6 to consider. The most common abelian groups are the cyclic groups Zₙ, and any group that is isomorphic to a direct sum of cyclic groups is also abelian.

It is known that the subgroups of S6 include the following abelian groups: Z₁, Z₂, Z₃, Z₆, Z₂ x Z₂, and Z₃ x Z₂. These are the only abelian groups that can be isomorphic to subgroups of S6. Note that there may be non-abelian subgroups of S6 as well.

The critical region for a hypothesis test consists of outcomes that have a very low probability if the null hypothesis is true. This means that if the null hypothesis is true, these outcomes should not occur. The critical region is used to decide when to reject the null hypothesis and accept the alternative hypothesis.

Hypothesis testing is a process used in statistics to determine whether a certain claim or hypothesis is valid. It involves collecting data, analyzing the data, and making decisions based on the analysis of the data. The goal of hypothesis testing is to either reject or accept a null hypothesis, which is an assumption that there is no relationship between two measured phenomena. Hypothesis testing can also be used to compare two groups or to determine the effectiveness of a treatment or intervention.

The probability of the union of events a and b is 0.21. the sum of their individual probabilities : P(a ∪ b) = 0.01 + 0.2 = 0.21.  Events a and b are mutually exclusive, it means that they cannot both happen at the same time.

In the event that occasions an and b are totally unrelated, it implies that the two of them can't occur simultaneously. In this way, the likelihood of their association (that is, the likelihood that either occasion an or occasion b will happen) is the amount of their singular probabilities:

P(a ∪ b) = P(a) + P(b)

Considering that P(a) = 0.01 and P(b) = 0.2, we can ascertain the likelihood of their association:

P(a ∪ b) = 0.01 + 0.2 = 0.21

In this way, the likelihood of the association of occasions an and b is 0.21.

The likelihood of occasion An incident is 0.01 and the likelihood of occasion B happening is 0.2. Assuming that these occasions are fundamentally unrelated, it implies the two of them can't occur simultaneously. The complete opportunity of either occasion An or occasion B happening is found by including the singular probabilities.

The probability that a bag of chip is lower than 9.07 oz of weight is 0.1587.

A continuous probability distribution for a real-valued random variable is called a normal distribution or a Gaussian distribution.

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the center of the range.

The normal distribution defines how a variable's values are distributed, just like any probability distribution does. Because it properly depicts the distribution of values for many natural occurrences, it is the most significant probability distribution in statistics.

the mean of the data = 9.12 oz

The SD = 0.05 oz

The probability of the bag to be less than 9.07 oz

x = 9.07

z = x - mean / SD = 9.07 - 9.12/0.05 = - 1

for z = -ve

Ф(z) = 1 - Ф(-z) = 1 - Ф(1) = 1 - 0.8413 = 0.1587

Given:

m∠B = 62°, a = 11, and c = 19

Now, b² = a² + c² - 2ac cos B.

b = √ a² + c² - 2ac cos B

b = √ 11² + 19² - 2x 11  x 19 cos 62

b= 16.9

Due to their four sides or more, triangles are considered polygons. It has a straightforward, geometric form. A triangle is a square angle formed by the letters ABC. A singular rectangle or square is produced by Euclidean geometry when the sides are still not collinear. Triangles are polygons because they have three sides and three corners.

Using the area of the rectangle and circle, the shaded area is equal to 6.88 squared units

To determine the area of the shaded region, we can simply find the area of the rectangle and the area of the circle.

The formula of area of the rectangle;

Assuming the width is half the length

Area of rectangle = length * width

Area of rectangle = 8 * 4

Area of rectangle = 32 squared units.

Area of circle = πr²

r = radius of the circle

In this problem, the diameter of the circle is the width of the rectangle or rather, the diameter of the circle is half the length of the the rectangle.

d = 8 / 2 = 4 units

radius = diameter / 2

radius = 4 / 2 = 2 units

Substituting the values into the formula

A = πr²

A = 3.14 * 2²

A = 3.14 * 4

A = 12.56 squared units.

The non-shaded area = 2 * 12.56 = 25.12 squared units.

The shaded area = area of rectangle - non-shaded area
