The statement "a line segment is a part of a line that is bounded by two distinct end points and contains every point on the line between its endpoints." is True because a line segment is defined as a part of a line that is bounded by two distinct end points and contains all the points on the line between those endpoints.

A line segment is a part of a line that has two endpoints and connects them. It is the shortest distance between two points and has a definite length, but no width or height. A line segment can be part of a straight line or a curved line.

A line segment is a section of a line that is defined by two distinct end points and includes every point on the line between them. It is the basic building block of geometry and can be used to measure distances, angles, and shapes.

The claim that the population mean is less than 125 (Option E) would

the interval tends to refute.

The 90% confidence interval for the population mean is 135 to 160. This means that if we were to repeat the process of taking samples from the same population and constructing a 90% confidence interval, we would expect 90% of the intervals to contain the true population mean.

With this in mind, let's consider each claim:

A. The interval does not rule out the possibility that the population mean is more than 110, as 110 is less than the lower bound of the interval.

B. The interval does not rule out the possibility that the population mean is less than 150, as 150 is greater than the upper bound of the interval.

C. The interval does not rule out the possibility that the population mean is between 140 and 150, as both of these values fall within the interval.

D. The interval does not rule out the possibility that the population mean is more than 140, as 140 is less than the upper bound of the interval.

E. The interval refutes the claim that the population mean is less than 125, as 125 is less than the lower bound of the interval.

Therefore, the answer is (E) The population mean is less than than 125.

The confidence interval for the proportion of adults who identify chocolate pie as their favorite pie, with a confidence level of 98%, is approximately  0.3248 to 0.8152 (rounded to four decimal places).

To calculate the confidence interval for the proportion of adults who identify chocolate pie as their favorite pie, we can use the formula:

Confidence Interval = Sample Proportion ± Margin of Error

First, let's calculate the sample proportion:Sample Proportion = Percentage/100 = 57/100 = 0.57

Next, we need to calculate the margin of error using the formula:Margin of Error = Critical Value * Standard Error

Since the confidence level is 98%, the alpha level (α) is 1 - 0.98 = 0.02. Since it is a two-tailed test, we divide the alpha level by 2, resulting in α/2 = 0.01.

The critical value can be found using a standard normal distribution table or a calculator, based on the alpha level. In this case, the critical value for a 98% confidence level is approximately 2.33.

The standard error is calculated as the square root of [(Sample Proportion * (1 - Sample Proportion)) / Sample Size].

Standard Error = sqrt[(0.57 * (1 - 0.57)) / 22]

Now we can calculate the margin of error: Margin of Error = 2.33 * sqrt[(0.57 * (1 - 0.57)) / 22]

Finally, we can calculate the confidence interval:Confidence Interval = Sample Proportion ± Margin of Error. Substituting the values: Confidence Interval = 0.57 ± Margin of Error

Therefore, the confidence interval for the proportion of adults who identify chocolate pie as their favorite pie, with a confidence level of 98%, is approximately 0.3248 to 0.8152 (rounded to four decimal places).

The correct answer is b) unchanged. Cutting a chocolate bar in half does not affect its density.

When a chocolate bar is cut in half, its density remains unchanged. Density is a physical property of a substance that is determined by its mass per unit volume. When the chocolate bar is cut in half, the mass is also divided into two equal parts, resulting in a reduction of the volume by half as well. Since both the numerator and denominator in the density formula change proportionally, the density remains the same.

For example, if the density of a chocolate bar is 1 gram per cubic centimeter, cutting it in half would result in two smaller bars, each with half the volume and half the mass. The density of each of the new bars would still be 1 gram per cubic centimeter, even though they are smaller in size.

Therefore, the correct answer is b) unchanged. Cutting a chocolate bar in half does not affect its density.

The statement Count = Count + 2 assigns the value of the Count variable to itself, incremented by two. Therefore, the answer to the question is B) 25.

We are given the initial value of the Count as 23. The statement Count = Count + 2 assigns the value of the Count variable to itself, incremented by two.

This implies that the value of Count is 23+2= 25 after the statement is executed.

In other words, the right-hand side of the equals sign is evaluated before the value is assigned to the left-hand side of the equals sign.

In this case, the right-hand side is Count + 2, which is equal to 23+2= 25.

The value 25 is then assigned to the variable Count on the left-hand side of the equals sign.

As a result, the value of Count after executing the statement Count = Count + 2 is 25.

Thus, option B) 25 is the correct answer to the given question.

The equation that we would use to find the value of x based on the area of a rectangle is:

C. (16 + 2x)(12 + 2x) = 396

To find the area of a rectangle, find the product of its length and its width. Thus, the area of a rectangle is: (length)(width) = area.

Given the following:

Area of both the walkway and the garden = 396 square meters

Length = x + 16 + x = 16 + 2x

Width = x + 12 + x = 12 + 2x

Using the area formula for a rectangle, we would have:

(16 + 2x)(12 + 2x) = 396.

The subgroup generated by (123)(45) has order 6 and is cyclic.

Group theory is a branch of mathematics that deals with the study of the properties of groups. A group is a set of elements that follows a specific set of rules.

The order of a group is the number of elements in the group.

The order of an element is the smallest positive integer n such that the element raised to the nth power is the identity element of the group.

This answer will cover the topic of \(\( A_{5} \)\) having a cyclic subgroup of order 6.

\(\( A_{5} \)\) is the alternating group of degree 5.

It is the group of even permutations of five objects. It contains 60 elements.

A cyclic group is a group that is generated by a single element.

The order of a cyclic group is the number of elements in the group. The subgroup of a group is a subset of the group that is itself a group. The order of a subgroup is the number of elements in the subgroup.

To show that \(\( A_{5} \)\) has a cyclic subgroup of order 6, we need to find an element of order 6 in \(\( A_{5} \)\) and show that the subgroup generated by that element is cyclic.

There are several ways to do this, but one way is to use the cycle notation for permutations. A permutation is a bijective function that maps a set to itself.

The cycle notation for a permutation is a way of writing the permutation as a product of disjoint cycles. A cycle is a sequence of elements that are moved by the permutation.

For example, the permutation (123)(45) means that 1 is moved to 2, 2 is moved to 3, 3 is moved to 1, 4 is moved to 5, and 5 is moved to 4.

The permutation (123)(45) has order 6 because (123)(45)(123)(45)(123)(45) = (154)(23).

This means that if we apply the permutation six times, we get back to the identity permutation.

Therefore, the subgroup generated by (123)(45) has order 6 and is cyclic.
