Answer:

7.5kg

Step-by-step explanation:

Given that:

Monday:

Mass of sand = 24 kg

Mass of cement = 5 kg

Tuesday :

Mass of sand = 36 kg

Let mass of cement = c

Mass of cement required to make the same type of mortar mix

Mass of Sand = mass of cement

24kg = 5kg

36kg = c

By cross multiplication :

24 * c = 5 * 36

24c = 180

Divide both sides by 24

c = 180 / 24

c = 7.5 kg

Hence mass of cement required is 7.5 kg

Based on the calculations, the slope of this line is equal to 50.

The slope of a line refers to the gradient of a line and it can be used to describe both the ratio, direction and steepness of an equation of a straight line.

Since the line passes through two (2) points, the slope of this line would be calculated by using this formula;

\(Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\)

Substituting the given parameters into the formula, we have;

Slope = (100 - 0)/(2 - 0)

Slope = 100/2

Slope = 50.

Based on the graph, we can deduce that the distance for each hour increases by 50 miles since Bill crossed the bridge.

The main answer to this question is that there could be several reasons why an experiment may not produce significant results even if the research hypothesis is true.

One possible explanation could be that the sample size used in the experiment was too small, which could have resulted in insufficient statistical power to detect the true effect of the independent variable on the dependent variable. Another explanation could be that there were extraneous variables that were not controlled for in the experiment, which could have influenced the results and made it difficult to detect the true effect of the independent variable.

it is important to consider all possible factors that may affect the results of an experiment and to take steps to minimize their impact. This includes ensuring that the sample size is appropriate, controlling for extraneous variables, and using appropriate statistical tests to analyze the data. By doing so, researchers can increase the likelihood of obtaining significant results that accurately reflect the effects of the independent variable on the dependent variable.

A principal amount of P 200,000 was deposited for a period of 4 years and 6 months, and it earned an interest of P 85,649.25. To find the rate of interest compounded monthly, we can use the formula for compound interest and solve for the interest rate.

The formula for compound interest is given by A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

In this case, we are given the principal amount P as P 200,000, the final amount A as P 285,649.25 (P 200,000 + P 85,649.25), the time t as 4 years and 6 months (or 4.5 years), and we need to find the interest rate r compounded monthly (n = 12).

Using the given values in the compound interest formula and solving for r, we can find the rate of interest. By rearranging the formula and substituting the known values, we can isolate the interest rate r and calculate its value.

Answer:

Route 1 is shorter

Step-by-step explanation:

Route 1:

3 + 10 + 2 = 15 units

Route 2:

3 + 3 + 4 + 4 + 3

= (6) + (8) + (3) = 20 units

Therefore, route 1 is 5 units shorter than route 2.

Answer:

Both routes are the same.

That's the answer.

Step-by-step explanation:

a) The high temperature for today using a 3-day moving average = 92.7 degrees.

b) The high temperature for today using a 2-day moving average = 91.5 degrees.

c) The mean absolute deviation based on a 2-day moving average = 1.5 degrees.

d) The mean squared error for the 2-day moving average = 2.25 degrees².

e) The mean absolute percent error (MAPE) for the 2-day moving average = 2.9%.

To calculate the high temperature for today using a 3-day moving average, we sum the high temperatures of the last three days (90, 93, and 95), and then divide the sum by 3. This gives us an average of 92.7 degrees, rounded to one decimal place.

For a 2-day moving average, we sum the high temperatures of the last two days (90 and 93), and divide the sum by 2. This gives us an average of 91.5 degrees, rounded to one decimal place.

To calculate the mean absolute deviation based on a 2-day moving average, we first find the absolute difference between each high temperature and the 2-day moving average (91.5 degrees). The differences are 1.5, 1.5, 1.5, 2.5, 3.5, and 1.5. Then, we calculate the average of these differences, which is 1.5 degrees, rounded to one decimal place.

The mean squared error for the 2-day moving average is calculated by squaring the differences between each high temperature and the 2-day moving average (91.5 degrees), and then finding the average of these squared differences. In this case, the squared differences are 2.25, 2.25, 2.25, 6.25, 12.25, and 2.25. The average of these squared differences is 4.83 degrees^2, rounded to one decimal place.

The mean absolute percent error (MAPE) for the 2-day moving average is calculated by finding the absolute difference between each high temperature and the 2-day moving average (91.5 degrees), dividing this difference by the high temperature, and then finding the average of these percentages. The percentages are 1.6%, 1.6%, 1.6%, 2.6%, 3.7%, and 1.6%. The average of these percentages is 2.9%, rounded to one decimal place.

The relationships described indicate that, without trade, the price of shoes relative to automobiles is lower in the United States compared to the Rest of the World.

In the given two-country two-good two-input model, the relationships suggest that the price of shoes relative to automobiles is lower in the United States compared to the Rest of the World. Let's now examine the relative labor endowment.

The relative labor endowment refers to the ratio of labor available in one country compared to another. Given that the capital-labor ratios for automobiles and shoes are higher in the United States than in the Rest of the World, it implies that the United States has a higher capital endowment relative to labor compared to the Rest of the World.

Since technology and tastes are assumed to be the same in both countries, the lower price of shoes relative to automobiles in the United States indicates that the labor input required for producing shoes is relatively higher in the United States compared to the Rest of the World.

This suggests that the United States has a higher labor endowment compared to the Rest of the World.

Therefore, based on the given relationships, we can conclude that the relative labor endowment in the United States is higher than in the Rest of the World.

100 same-day tickets were sold for the cost using equation.

To solve this problem, we can use a system of two equations with two variables. Let x be the number of advance tickets sold and y be the number of same-day tickets sold. Then we have:

x + y = 600   (equation 1: total number of tickets sold)
50x + 30y = 28000   (equation 2: total amount paid for tickets)

We can solve for x and y by using elimination or substitution. Here's one way to do it using substitution:
From equation 1, we have y = 600 - x. Substitute this into equation 2:

50x + 30(600 - x) = 28000

Simplify and solve for x:
50x + 18000 - 30x = 28000
20x = 10000
x = 500

So 500 advance tickets were sold. To find the number of same-day tickets, we can substitute x = 500 into equation 1:

500 + y = 600
y = 100

So 100 same-day tickets were sold.

The average length encoding of a letter for a Huffman code of the letters and their given frequencies will be 245.

We have,

Frequencies:

a = 0.15 = 15,

b = 0.25 = 25,

c = 0.20 = 20,

d = 0.35 = 35,

e = 0.05 = 5,

So,

Now,

According to the question,

We will make Huffman tree,

i.e.

a = 0.15 = 15,

b + c = 25 + 20 = 45

d + e = 35 + 5 = 40,

Now,

a + b + c + d + e = 100

So,

a = 11 = 2 digits

b = 101 = 3 digits

c= 100 = 3 digits

d= 01 = 2 digits

e= 00 = 2 digits

And,

We know that,

Total bits required to represent Huffman code = 12.

So,

Now,

The average code length = a * 2 digits + b * 3 digits + c * 3 digits + d * 2 digits + e * 2 digits

i.e.

The average code length = 15 × 2 + 25 × 3 + 20 × 3 + 35 × 2 + 5 × 2

On solving we get,

The average code length = 245

Hence we can say that the average length encoding of a letter for a Huffman code of the letters and their given frequencies will be 245.

To find the area of each light, we can use the formula for the area of a circle, which is A = πr². By substituting the given value of pi as 3.14 and knowing the radius of each light, we can calculate their respective areas.

The formula for the area of a circle is A = πr², where A represents the area and r is the radius of the circle. In this case, we are given that pi is equal to 3.14. To find the area of each light, we need to know the radius of each circle.

Once we have the radius value for each light, we can substitute it into the formula to calculate the area. By squaring the radius and multiplying it by pi, we obtain the area. It is important to note that the radius should be in the same unit as the desired area (e.g., if the radius is in meters, the area will be in square meters).

By following these steps for each light, we can determine the area of each one separately. Remember to double-check the given radius values and ensure they are accurate before calculating the areas.

A) 24 machines, working simultaneously and independently at this constant rate, can produce a total of 3x units of product P in 4 days..

Let's analyze the given information and use it to determine the number of machines required to produce 3x units of product P in 4 days.

We are told that 4 machines can produce a total of x units of product P in 6 days. This means that the rate at which these 4 machines produce the product is x/(4 * 6) units per day.

To find the number of machines required to produce 3x units of product P in 4 days, we can set up a proportion based on the rates:

(x units / (4 machines * 6 days)) = (3x units / (N machines * 4 days))

Simplifying the proportion:

1/(4 * 6) = 3/(N * 4)

Multiplying both sides by 4:

1/24 = 3/N

Cross-multiplying:

N = 24/1

N = 24

Therefore, the number of machines required to produce 3x units of product P in 4 days is 24.

The answer is option A. 24.

Exponential decay

Step-by-step explanation:

The general form of an exponential function is

\(P=P_{0}a^t\), where P0 is the initial value, a is the base, and t is the exponent.

In your example, P0 is 1 and a is 4/5.

A function is experiencing exponential growth when a > 1.

A function is experiencing exponential decay when 0 < a < 1.

4/5 lies between 0 and 1, so the function is experiencing exponential decay.
