The figure above shows a cement block of
36 cm x 20 cm x 9 cm with two 10 cm x 8 cm
openings. What is the weight of the cement block
to the nearest gram? (The density of cement is
1.7 gram/cm
cm)
A) 5,040
B) 6,048
C) 7,560
D) 8,568

Answer:

∠A=123°.

Step-by-step explanation:

From the given figure it is clear the CD and CE are two tangent lines on circle with center A.

Radius is perpendicular to the tangent at the point of tangency.

\(\angle ADC=90^{\circ}\)

\(\angle AEC=90^{\circ}\)

Smaller arc DE = (5x-2)°

It means central angle DAE is (5x-2)°.

\(\angle DAE=(5x-2)^{\circ}\)

Now, ADCE is a quadrilateral and sum of all angles of a quadrilateral is 360 degrees.

\(\angle ADC+\angle DCE+\angle AEC+\angle DAE=360^{\circ}\)

\(90^{\circ}+(2x+7)^{\circ}+90^{\circ}+(5x-2)^{\circ}=360^{\circ}\)

\((7x+5)^{\circ}+180^{\circ}=360^{\circ}\)

\((7x+5)^{\circ}=360^{\circ}-180^{\circ}\)

\((7x+5)^{\circ}=180^{\circ}\)

\(7x+5=180\)

\(7x=175\)

\(x=25\)

The value of x is 25.

\(\angle A=5x-2=5(25)-2=125-2=123^{\circ}\)

Therefore, the measure of ∠A is 123°.

Answer:

Step-by-step explanation:

50 * 3 = 150.

a).  2^38 bytes of memory

b). 12 bits

c). The maximum number of entries in the single-level page table would be 2^38.

d). The size would be 2^38 * 4KB, which equals 2^20 pages.

e). The maximum number of entries it can have depends on the remaining bits of the logical address.

f). The amount of bits required to denote an index into the inner page table is obtained by subtracting the offset and outer page index bits from the logical address.

a. To address a physical memory size of 128GB (2^37 bytes), a 64-bit architecture would require 38 bits for the logical address, allowing access to a maximum of 2^38 bytes of memory.

b. Given that the page size is 4KB (2^12 bytes), 12 bits would be needed to specify the displacement into a page. This means that the lower 12 bits of the logical address would be used for page offset or displacement.

c. With a single-level page table, the maximum number of entries would be equal to the number of possible logical addresses. In this case, since the logical address requires 38 bits, the maximum number of entries in the single-level page table would be 2^38.

d. The size of the single-level page table is determined by the number of entries it contains. Since each entry maps to a page of size 4KB, the size of the single-level page table can be calculated by multiplying the number of entries by the size of each entry. In this case, the size would be 2^38 * 4KB, which equals 2^20 pages.

e. For a two-level page table, the size of the outer page table is determined by the number of entries it can contain. Since the outer page table uses 4KB pages, the maximum number of entries it can have depends on the remaining bits of the logical address. The number of bits used for the index into the outer page table is determined by subtracting the bits used for the inner page index and the offset from the total number of bits in the logical address.

f. The number of bits used to specify an index into the inner page table can be determined by subtracting the bits used for the offset and the bits used for the outer page index from the total number of bits in the logical address. The remaining bits are then used to specify the index into the inner page table.

The average effect size of each gene on the trait would be 17.6 / 100 = 0.176 grams, and the minimum number of genes affecting this trait would be estimated as 2.47.

To estimate the minimum number of genes affecting this trait, we can use Falconer's formula:

Vg = (n/2) * (1/n) * (π * a)^2,

where:

Vg is the genotypic variance

n is the number of genes affecting the trait

a is the average effect size of a single gene on the trait

We can rearrange this formula to solve for n:

n = 2 * Vg / (π * a)^2

Given that Vg = 0.88, and the difference in mean phenotype between the two strains is 17.6 grams, we can estimate a as follows:

a = 17.6 / (number of genes affecting the trait)

Substituting a in the formula for n, we get:

n = 2 * Vg / (π * (17.6/n))^2

Simplifying this expression, we get:

n = 2 * 0.88 / (π * (17.6/n))^2

n = 0.5 / (π^2 * (17.6/n)^2)

We can now use trial and error or iterative methods to solve for n. For example, we can plug in different values of n until we find a value that satisfies the equation.

Let's try n = 100:

n = 0.5 / (π^2 * (17.6/100)^2)

n = 0.5 / (3.1416^2 * 0.176^2)

n = 2.47

This means that if 100 genes were involved, the average effect size of each gene on the trait would be 17.6 / 100 = 0.176 grams, and the minimum number of genes affecting this trait would be estimated as 2.47. However, this is just an estimate and the actual number of genes affecting the trait may be different.

The probability of randomly getting the red marbles from both Jar A and Jar B is 8/25.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

So, the probability that both marbles will be red is:

Probability formula: P(E) = Favourable events/Total events

We know that:

Jar A: 4 red marbles and 6 blue marbles

The probability of randomly choosing red marble is:

P(E) = Favourable events/Total events

P(E) = 4/10

P(E) = 2/5

Jar B: 8 red marbles and 2 blue marbles

The probability of randomly choosing red marble is:

P(E) = Favourable events/Total events

P(E) = 8/10

P(E) = 4/5

So, the total probability will be:

2/5 * 4/5

8/25

Therefore, the probability of randomly getting the red marbles from both Jar A and Jar B is 8/25.

Incidence density rate ratio, hazard ratio, and cumulative incidence risk ratio are typically used in longitudinal or cohort studies rather than cross-sectional studies.

Measures of association that can be computed in a cross-sectional study include the following:

Prevalence odds ratio: The prevalence odds ratio compares the odds of a certain outcome or exposure between different groups in a cross-sectional study. It is commonly used to assess the association between a binary outcome and a binary exposure in a population at a specific point in time.

Relative risk: Relative risk, also known as risk ratio, compares the risk of an outcome between different groups in a cross-sectional study. It measures the ratio of the probability of an outcome occurring in one group compared to another group. Relative risk is commonly used to assess the association between an exposure and an outcome in a cross-sectional study.

The measures of association listed above, prevalence odds ratio and relative risk, are commonly used in cross-sectional studies to evaluate the relationship between exposures and outcomes. However, it's important to note that measures such as incidence density rate ratio, hazard ratio, and cumulative incidence risk ratio are typically used in longitudinal or cohort studies rather than cross-sectional studies.

Step-by-step explanation:

In general, economists are critical of monopoly when there is a lack of competition in the market. Hence, option 1) is correct.

This includes situations where there are only a few firms operating in the market, as well as situations where there is a natural monopoly, which occurs when the most efficient market structure involves only one firm due to high fixed costs. However, even in cases of persistent economies of scale where it may seem like a monopoly is necessary for efficiency, economists still tend to be critical as monopolies can lead to higher prices, lower quality products, and reduced innovation.

A monopoly in economics is a scenario when one business or entity has complete control over the production and distribution of a specific good or service. Due to the monopolist's ability to set prices above what the market would otherwise bear, there would be less consumer surplus and associated inefficiencies. Monopolies can develop as a result of entry-level restrictions, such as expensive beginning fees or legal requirements, or through acquiring rival businesses. Monopolies may be regulated or dismantled by governments in an effort to boost competition and safeguard the interests of consumers. Monopolies are a fundamental idea in industrial organisation and have significant effects on the composition and operation of markets.
