a. The new expression that is showing the distributive division for each of the 12 parts is 3p – 4

b. The equation of length of each 12 equal division of pipes using the distributive property of division is 3p – 4

Given: Expression 36p – 48 representing the total distance of piping.

To simplify for the portions the needs to divide the pipe into 12 equal halves.

What is the distributive Property of division?

The distributive property of division states that for a division if we divide the numerator or the dividend into smaller parts that are exactly divisible by the denominator or the divisor respectively, and then add all the quotients of the smaller divisions then the answer will be exactly same as dividing the larger number without breaking into smaller parts.

Let’s solve the given question:

The total distance of piping = 36p – 48

a. Now total distance of piping will have to be divided into 12 equal parts.

Let’s say the equation of the sizes of each part be x

Then the sum of all the 12 parts will be equal to 36p – 48

So x + x + …. 12 times = 36p – 48

=> 12x = 36p – 48

Dividing both sides by 12:

12x / 12 = (36p – 48) 12

x = 3p – 4

The new expression that is showing the distributive division for each of the 12 parts is 3p – 4

b. We have to use the Distributive property to show the division of piping for her job

Now the pipe of length 36p – 48 has to be divided into 12 equal parts

So length of each part is (36p – 48) / 12

We can write 36p – 48 as {(12p – 24) + (24p – 12)}

So (36p – 48) / 12 = {(12p – 24) + (24p – 12)} / 12

= (12p – 24) / 12 + (24p – 24) / 12

= 12p / 12 – 24 / 12 + 24p / 12 – 24 / 12

= p – 2 + 2p – 2

= 3p – 4

So the equation of length of each 12 equal division of pipes is 3p – 4

Hence

a. The new expression that is showing the distributive division for each of the 12 parts is 3p – 4

b. The equation of length of each 12 equal division of pipes using the distributive property of division is 3p – 4

The value of the digit 5 in the tenths place of 3.545 is 100 times the value of the digit 5 in the thousandths place.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

Evan has a bag of apples that weighs 3.545 pounds.

The value of the digit 5 in the tenths place of 3.545 is 0.500

The value of the digit 5 in the thousandths place of 3.545 is  0.005

Take the ratio of both values:

tenths place value/thousandths place value =  0.500/0.005

tenths place value/thousandths place value =  100

tenths place value = 100(thousandths place value)

Thus, the value of the digit 5 in the tenths place of 3.545 is 100 times the value of the digit 5 in the thousandths place.

Equivalent Ratios:

When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another. For instance, the ratios 1:2 and 2:4 are equivalent.

To put it another way, two ratios are said to be equivalent if one of them can be written as the multiple of the other. Therefore, we must multiply the two values (antecedent and consequent) by the same number in order to obtain the equivalent ratio of another ratio.

Answer:

[(6 + x) / 13+x] = 0.65

7

Step-by-step explanation:

Given that:

Total number of games = 13

Number of correct prediction = 6

Number of correct predictions needed to raise prediction % to 65%

(Number of correct predictions) / (total number of games) = 0.65

Let x = number of additional consecutive correct predictions

[(6 + x) / 13+x] = 0.65

Where x = number of consecutive predictions required

6 + x = (13 + x) * 0.65

6 + x = 8.45 + 0.65x

x - 0.65x = 8.45 - 6

Answer:

\(254 \frac{12}{17}\) or approximately 254.71

Step-by-step explanation:

First, you need to find out how many gallons it will take to travel 866 miles. Because the car's avg miles/gallon is 13.6, you divide 866 by 13.6. However, this gets you an irrational number. To avoid this, make 13.6 into a fraction. Now divide 866 by \(13 \frac{3}{5}\). This becomes 866 ÷ \(\frac{68}{5}\). Convert this into a multiplication problem by converting \(\frac{68}{5}\) into its reciprocal. This gets you 866 × \(\frac{5}{68}\). This gets you \(\frac{2165}{34}\). Now that you have the amount of gallons it will take to get to your destination, multiply it by 4. \(\frac{2165}{34}\) × \(4\)\(= \frac{4330}{17}\). This becomes \(254 \frac{12}{17}\) or approximately 254.71.

The cost for the river-facing side is $9 per foot, while the cost for the other sides is $6 per foot. With a total budget of $1,458, we want to find the length of the river-facing side that will result in the maximum area.

To maximize the fenced area, we need to determine the length of the side facing the river that will give us the maximum area within the given budget. Let's denote the length of the river-facing side as x. The cost of the river-facing side will then be 9x, and the cost of the other sides will be 6(2x) = 12x. The total cost of the fence will be 9x + 12x = 21x.

Since we have a budget of $1,458, we can set up the equation:

21x = 1,458

Solving for x, we find x = 1,458 / 21 ≈ 69.43.

Therefore, the length of the side facing the river should be approximately 69.43 feet in order to maximize the fenced area within the given budget.

The probability of being dealt a royal flush in poker is 4 / C(52, 5).

The probability of being dealt a royal flush in poker can be calculated by considering the number of ways to obtain a royal flush and dividing it by the total number of possible poker hands.

1. Determine the number of ways to obtain a royal flush: A royal flush consists of the ace, king, queen, jack, and 10 of the same suit. There are 4 suits in a standard deck, so there are 4 possible royal flushes, one for each suit.

2. Calculate the total number of possible poker hands: To do this, we need to consider the number of ways to choose 5 cards from a deck of 52 cards. This can be calculated using the combination formula: C(52, 5) = 52! / (5! * (52 - 5)!), where "!" denotes factorial.

3. Divide the number of ways to obtain a royal flush by the total number of possible poker hands to get the probability: P(royal flush) = Number of ways to obtain a royal flush / Total number of possible poker hands.

Thus, the probability of being dealt a royal flush in poker is 4 / C(52, 5).

The rows selected for the predicate "enrol_mark >= 50" by the DBMS will include all rows where the value of the column "enrol_mark" is greater than or equal to 50.

In a DBMS (Database Management System), a predicate is a condition or criteria used to filter and select specific rows from a database table. In this case, the predicate "enrol_mark >= 50" indicates that we are interested in selecting rows where the value of the "enrol_mark" column is greater than or equal to 50.

When the DBMS evaluates this predicate, it will scan the table and compare the value of the "enrol_mark" column for each row. If the value is greater than or equal to 50, the row will be selected and included in the result set. Rows with "enrol_mark" values less than 50 will not be included in the result set.

It's important to note that the actual rows selected by the DBMS will depend on the specific data in the table. If there are rows where the "enrol_mark" column has values greater than or equal to 50, those rows will be selected. If there are no such rows, then the result set will be empty.

Moving Average leads a trend, True. Mean Squared Error cannot be used to compare alternative forecasting methods, False. Delphi method uses multiple rounds for determining estimates, True.

True. Moving Average is a commonly used time series forecasting technique that calculates the average of a specified number of past data points to predict future values. It is known as a lagging indicator because it uses historical data to forecast trends. By smoothing out fluctuations in the data, moving averages provide a clearer picture of the underlying trend. Therefore, it can be said that moving averages lead a trend.

False. Mean Squared Error (MSE) is a measure used to assess the accuracy of a forecasting model by comparing its predicted values to the actual values. It calculates the average of the squared differences between the predicted and actual values. While MSE is a useful metric for evaluating the performance of a single forecasting method, it cannot be directly used to compare alternative forecasting methods.

This is because MSE values are scale-dependent, meaning they can vary depending on the units of measurement. In order to compare alternative methods, it is recommended to use other metrics like Mean Absolute Error (MAE) or forecasting accuracy measures such as Mean Absolute Percentage Error (MAPE).

True. The Delphi method is a forecasting technique that involves multiple rounds of gathering expert opinions to reach a consensus or determine estimates. In each round, a panel of experts provides their individual forecasts or opinions on a particular topic. These responses are collected, summarized, and fed back to the experts for further consideration. This process continues for several rounds until a convergence or consensus is reached.

The Delphi method is designed to harness the collective intelligence and expertise of a diverse group of experts while minimizing the influence of dominant individuals or group dynamics. The iterative nature of the Delphi method allows for refining and revising estimates based on feedback, resulting in a more reliable and accurate forecast.

Answer:

Step-by-step explanation:

First of all, I have a strong feeling that that is supposed to be

\(log_2(32)=y\) so I'm going to go with that. We can solve for y by rewriting that in exponential form. Exponential form and log form are inverses of each other. If the log form of an equation is

\(log_b(x)=y\), the exponential form of it is

\(b^y=x\). We will apply that here to solve for y:

\(2^y=32\)

which is asking us, "2 to the power of what equals 32?". We can use our calculator to raise 2 to consecutive powers til we reach the one that gives us a 32, or we could solve it by writing the 32 in terms of a 2:

\(2^y=2^5\)

Since both bases are the same, 2, then the exponents are equal to one another. y = 5. This is an important rule to remember while solving either log or exponential equations.
