Solving log12 20,736 is 3
How to solve log12 20,736To solve for log12 20,736, we need to determine what power of 12 is equal to 20,736.
We can do this by repeatedly dividing 20,736 by 12 until we get a quotient less than 12:
20,736 / 12 = 1,728
1,728 / 12 = 144
144 / 12 = 12
So we can write 20,736 as 12 raised to the power of 3 (since we divided by 12 three times):
20,736 = 12^3

In the revenue equation R = –360p2 + 28,800p, what is the maximum revenue that can be expected?
Group of answer choices
The revenue equation is given by:
R = –360p^2 + 28,800p
To find the maximum revenue that can be expected, we need to find the vertex of the parabola represented by this equation. The vertex of a parabola is given by the formula:
Vertex = (-b/2a, f(-b/2a))
where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.
In this case, a = -360 and b = 28,800.
The x-coordinate of the vertex is given by:
x = -b/2a = -28,800/(2*(-360)) = 40
Substituting x = 40 into the revenue equation gives:
R = –360(40)^2 + 28,800(40) = 576,000
Therefore, the maximum revenue that can be expected is $576,000.

An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.
Given,
Choose two columns from the paired ordered columns. Using (2, 4) and (3,6)
The x and y values are 2 and 3, respectively, and the

The mean of birth weights for individual babies in the population is 3,500 grams. What is the mean birth weight for the sampling distribution for samples of 100 babies?
Answer:
The mean birth weight for the sampling distribution is
3,500 grams.
Step-by-step explanation:
The sample mean is the average of the sample values collected divided by the number of the samples, while the population mean is the average or mean of all the values in the population. If the sample is random and the sample size is large enough, then the sample mean would be a good estimator of the population mean. This implies that with a randomly distributed and unbiased sample size, the sample mean and population mean will be equal, according to the central limit theorem. Therefore, the mean of the sample means will always approximate the population mean.
A quality control expert at Glotech computers wants to test their new monitors. The production manager claims they have a mean life of 75 months with a standard deviation of 5 months. If the claim is true, what is the probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
Answer:
86.65% probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Population: \(\mu = 75, \sigma = 5\)
Sample of 85: \(n = 85, s = \frac{5}{\sqrt{85}} = 0.5423\)
If the claim is true, what is the probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
This is 1 subtracted by the pvalue of Z when X = 74.4. So
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem
\(Z = \frac{X - \mu}{s}\)
\(Z = \frac{74.4 - 75}{0.5423}\)
\(Z = -1.11\)
\(Z = -1.11\) has a pvalue of 0.1335
1 - 0.1335 = 0.8665
86.65% probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors

[~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T by substituting the propositional variables.
What is truth table?A truth table is a table used to determine the truth values of a compound proposition, which is a logical statement made up of simpler propositions using logical operators such as "and" (represented by "&"), "or" (represented by "V"), "not" (represented by "~"), conditional (represented by "⊃"), and biconditional (represented by "≡").
According to question:Let's substitute the given truth values for the propositional variables in the given statement:
[~F & (F V F)] ≡ (T ⊃ F)
Using the truth table for conjunction (represented by "&") and disjunction (represented by "V"), we can simplify the left-hand side of the equivalence:
[T & F] ≡ (T ⊃ F)
Using the truth table for conditional (represented by "⊃"), we can simplify the right-hand side of the equivalence:
F ≡ F
Since both sides of the equivalence have the same truth value, the statement is true.
Therefore, [~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T.

The histogram below shows information about the ages of 54 houses in a village.
Work out an estimate for the median age of these houses. If your answer is a decimal, give it to 1 d.p.
From the histogram, it appears that the median age of the houses is approximately 35 years.
What is median age?Median number is the middle value in a set of numbers. It is determined by first listing all the numbers in an ascending or descending order and then finding the value in the middle of the set. Median number is used to measure the central tendency of the data set, or the average of the values, as it is not affected by outliers and large values. It gives a more accurate picture of the data set compared to the mean.
This can be estimated by looking at the midpoint of the bars on the histogram. As the bars indicate, there is an even distribution of houses that are older and younger than this figure, and so it can be assumed that the median age of the houses is 35 years. This is supported by the fact that the highest bar on the histogram is at the 35 year mark, indicating that this is the most common age of the houses in the village.
The fact that the figure of 35 is a good estimate for the median age of the houses can be further supported by looking at the information that is provided in the histogram. It can be seen that there are 27 houses that are older than 35 years, and 27 houses that are younger than 35 years. This indicates that half of the houses are older than 35 years, and half of the houses are younger than 35 years, which confirms that 35 years is a good estimate for the median age of the houses in the village.

2. Triangle GHI with vertices G(-1,6), H(-1,3), and I(-6, 6):
a) translation along the vector (7,-5)
b) reflection in the line y = -3
Answer:
a) The vertices of the triangle G'H'I' are \(G'(x,y) = (6, 1)\), \(H'(x,y) = (6,-2)\) and \(I'(x,y) = (1, 1)\), respectively.
b) The triangle G''H''I'' have vertices at \(G''(x,y) = (-3,-12)\), \(H''(x,y) = (-1, -9)\) and \(I''(x,y) =(-6,-12)\).
Step-by-step explanation:
a) From Linear Algebra, we define the translation by the following vector:
\(O'(x, y) = O(x,y) +T(x,y)\) (1)
Where:
\(O(x,y)\) - Original point, dimensionless.
\(O'(x,y)\) - Translated point, dimensionless.
\(T(x,y)\) - Translation vector, dimensionless.
If we know that \(G(x,y) = (-1,6)\), \(H(x,y) =(-1,3)\), \(I(x,y) = (-6,6)\) and \(T(x,y) = (7,-5)\), then the vertices of the triangle G'H'I' are, respectively:
\(G'(x,y) = G(x,y) +T(x,y)\) (2)
\(G'(x,y) = (-1,6) +(7,-5)\)
\(G'(x,y) = (6, 1)\)
\(H'(x,y) = H(x,y) + T(x,y)\) (3)
\(H'(x,y) = (-1,3) + (7,-5)\)
\(H'(x,y) = (6,-2)\)
\(I'(x,y) =I(x,y)+T(x,y)\) (4)
\(I'(x,y) = (-6,6) +(7,-5)\)
\(I'(x,y) = (1, 1)\)
The vertices of the triangle G'H'I' are \(G'(x,y) = (6, 1)\), \(H'(x,y) = (6,-2)\) and \(I'(x,y) = (1, 1)\), respectively.
b) From Linear Algebra, we define the reflection with respect to a horizontal line as follows:
\(O''(x,y) = O(x,y) - 2\cdot [O(x,y)-R(x,y)]\) (5)
Where:
\(O(x,y)\) - Original point, dimensionless.
\(R(x,y)\) - Reflection point, dimensionless.
If we know that \(G(x,y) = (-1, 6)\) and \(R(x,y) = (-1,-3)\), then the location of point G'' is:
\(G''(x,y) =G(x,y) -2\cdot [G(x,y)-R(x,y)]\) (6)
\(G''(x,y) = (-1,6)-2\cdot [(-1,6)-(-1,-3)]\)
\(G''(x,y) = (-1,6) -2\cdot (0,9)\)
\(G''(x,y) = (-1,6)-(2,18)\)
\(G''(x,y) = (-3,-12)\)
If we know that \(H(x,y) =(-1,3)\) and \(R(x,y) = (-1,-3)\) , then the location of the point H'' is:
\(H''(x,y) =H(x,y) -2\cdot [H(x,y)-R(x,y)]\) (7)
\(H''(x,y) = (-1,3)-2\cdot [(-1,3)-(-1,-3)]\)
\(H''(x,y) = (-1, 3) -2\cdot (0,6)\)
\(H''(x,y) = (-1,3)-(0,12)\)
\(H''(x,y) = (-1, -9)\)
If we know that \(I(x,y) = (-6,6)\) and \(R(x,y) = (-6, -3)\), then the location of the point I'' is:
\(I''(x,y) =I(x,y) -2\cdot [I(x,y)-R(x,y)]\) (8)
\(I''(x,y) = (-6,6)-2\cdot [(-6,6)-(-6,-3)]\)
\(I''(x,y) = (-6,6)-2\cdot (0,9)\)
\(I''(x,y) = (-6,6)-(0,18)\)
\(I''(x,y) =(-6,-12)\)
The triangle G''H''I'' have vertices at \(G''(x,y) = (-3,-12)\), \(H''(x,y) = (-1, -9)\) and \(I''(x,y) =(-6,-12)\).

Tuesday: 88
Wednesday: 85
Thursday: 88
Friday: 99
Saturday: 134
Sunday: 129
Your response must have MORE than 5 complete sentences for this assignment!
Susannah's data are illustration of measure of central tendencies
(a) The mean
To calculate the mean, she needs to divide the total number of turkey sandwiches sold, by the number of days.
The total is:
\(\mathbf{Total = 73 +88+85+88+99+134+129}\)
\(\mathbf{Total = 696}\)
The number of days is:
\(\mathbf{Day = 7}\)
So, the mean is:
\(\mathbf{Mean =\frac{Total}{Days}}\)
\(\mathbf{Mean =\frac{696}{7}}\)
\(\mathbf{Mean =99.4}\)
Hence, the mean number of turkey sandwiches sold is 99.4
(b) The median
To calculate the median, she needs to arrange the data in ascending or descending order, then select the middle item.
In ascending order, we have: 73, 85, 88, 88, 99, 129, 134
The middle item is 88
So:
\(\mathbf{Median = 88}\)
Hence, the median number of turkey sandwiches sold is 88
(c) The mode
This is the data that occurs most.
From the dataset, 88 appears twice (more than others).
So:
\(\mathbf{Mode = 88}\)
Hence, the mode number of turkey sandwiches sold is 88
(d) The range
This is the difference between the highest and least data
From the dataset,
The highest is 134, and the least is 73
So:
\(\mathbf{Range =134 - 73}\)
\(\mathbf{Range =61}\)
Hence, the range of turkey sandwiches sold is 61
The measure that would be most helpful is the median, because it is not affected by outliers.

The area of a rectangle with a width of 5.1 cm and a height of 11.2 cm is 57.12 cm².
To find the area of a rectangle, we multiply its length by its width. In this case, the width is given as 5.1 cm and the height (or length) is given as 11.2 cm.
Area = length × width
Area = 11.2 cm × 5.1 cm
Calculating the product, we get:
Area = 57.12 cm²
Therefore, the area of the rectangle is 57.12 cm².
The correct answer is: 57.12 cm².
It is important to note that when calculating the area of a rectangle, we should always include the appropriate unit of measurement (in this case, cm²) to indicate that we are dealing with a two-dimensional measurement. The area represents the amount of space covered by the rectangle's surface.

Kay loves to save coins. She has a piggy bank that she has been filling for a long time with only dimes and nickels. Recently, her piggy bank was filled to the brim so Kay counted her coins and she discovered that she had $10. She also noticed that she has 11 less dimes than nickels. How many coins were in Kay's bank?
The total number of coins that were in Kay's bank are 137 coins.
How to determine the number of coins?In order to determine the number of dimes and nickels, we would assign a variables to the unknown numbers and then translate the word problem into algebraic equation as follows:
Let d represent the number of dimes.Let n represent number of nickels.Since she has 11 less dimes than nickels, an equation which models this situation is given by;
n = d + 11 ....equation 1.
Note: 1 nickel is equal to 0.05 dollar and 1 dime is equal to 0.1 dollar.
Additionally, the coins are worth 10 dollars;
0.1d + 0.05n = 10 ....equation 2.
By solving both equations simultaneously, we have:
0.1d + 0.05(d + 11) = 10
0.1d + 0.05d + 0.55 = 10
0.15d = 9.45
d = 63 dimes.
For nickels, we have:
n = d + 11
n = 63 + 11
n = 74
Now, we can determine the total number of coins;
Total number of coins = n + d
Total number of coins = 74 + 63
Total number of coins = 137 coins.
