Suppose that you construct a histogram and a relative frequency histogram corresponding to a particular frequency table. Identify one way the histograms will differ.
The classes will have different relative widths.
They will have a different number of classes.
The y-axis units will differ.
The one way the histogram will differ is C) The y-axis units will differ.
What is histogram?
A grouped frequency distribution with continuous classes is graphically represented by a histogram. It is an area diagram, and its size is proportional to the frequencies in the associated classes. Due to the base's coverage of the spaces between class boundaries, all of the rectangles in such representations are contiguous.
Given that you construct a histogram and a relative frequency histogram corresponding to a particular frequency table.
Histogram is representing actual frequency for a class interval in numbers.
But relative histogram gives the ratio of actual frequency to the sum of frequencies.
Thus histogram gives actual while relative histogram gives ratio.
Histogram figures may be greater than 1, but relative histogram figures are always less than 1.
Hence the correct option is C) The y-axis units will differ.

The level of inventory that, when reached, drives a new order to be placed to ensure proper inventory is maintained, is known as the reorder point. Your store is operational 156 days per year for business. Your annual demand is 18,575 items of product. The lead time to receive an inbound shipment order to resupply your store is 14 days. When the inventory falls to what approximate level should a new order be placed, using reorder point
When the inventory falls to approximately 1,832.91 items, a new order should be placed to ensure proper inventory is maintained for being the store operational for 156 business days.
To calculate the reorder point, we need to consider the demand during lead time as well.
First, we need to find the average daily demand:
Annual demand = 18,575 items
Average daily demand = Annual demand / Operational days
= 18,575 / 156
= 119.02 items per day
Next, we need to calculate the demand during lead time:
Lead time demand = Average daily demand x Lead time
= 119.02 x 14
= 1,666.28 items
Now, we can calculate the reorder point:
Reorder point = Lead time demand + Safety stock
We don't have information on the safety stock, so let's assume it's 10% of the lead time demand:
Safety stock = 10% x Lead time demand
= 10% x 1,666.28
= 166.63 items
Reorder point = 1,666.28 + 166.63
= 1,832.91
Therefore, when the inventory falls to approximately 1,832.91 items, a new order should be placed to ensure proper inventory is maintained.

(a)Offspring survivorship, S, for another bird species decreases with clutch size, C, as S = 0.5 - 0.1C. What is the optimal clutch size for this species? Again, assume that the bird lays one clutch per year, regardless of how many eggs are in the clutch. (b) Find a symbolic expression for optimal clutch size in a species that has a survivorship-clutch size relationship of the form S = a - bC
The optimal clutch size is 1.
a)The survivorship of an offspring, S, decreases with the clutch size, C.
Therefore, the formula is given as:
S = 0.5 - 0.1C
We need to find the optimal clutch size for this bird species.
We can do this by differentiating S with respect to C, and equating the result to zero.
That is:S = 0.5 - 0.1C => dS/dC = -0.1
Equating dS/dC to zero gives:-0.1 = 0 => C = 0
This implies that there is no optimal clutch size for this species.
However, since C represents clutch size, it must be a positive integer.
Therefore, we can choose a clutch size of 1, which will result in the highest survivorship of offspring. Hence, the optimal clutch size is
1.b)The optimal clutch size for a species with a survivorship-clutch size relationship of the form S = a - bC can be obtained by following the same procedure as above.
We can differentiate S with respect to C, and equate the result to zero.
That is:S = a - bC => dS/dC = -b
Equating dS/dC to zero gives:-b = 0 => C = 0
This implies that there is no optimal clutch size for this species. However, since C represents clutch size, it must be a positive integer. Therefore, we can choose a clutch size of 1, which will result in the highest survivorship of offspring. Hence, the optimal clutch size is 1.

A common everyday counting unit that is used to mean 12 of an object is a Dozen
Dozen is derived from the Old French word "douzaine" which means twelve each. In most situations, a dozen is used to refer to a group of twelve items. The term dozen is also used in informal situations to refer to a very large number of objects. For example, one might say "I have dozens of friends!" to mean that they have a lot of friends.
Dozen is a useful term when counting items. It allows for large numbers to be easily broken down into manageable groups. For example, if you have 120 pencils, you could easily count them by saying that you have 10 dozen pencils. It can also be useful when talking about fractions. For example, instead of saying "one and a half of an item," one could say "one and a half dozen of an item."
Dozen is a common everyday counting unit that is used to mean 12 of an object. It is a useful term when counting items and when talking about fractions, and can be used in both formal and informal settings.

How do I determine whether a graph is a function?
Here's a more detailed explanation: To determine if a graph is a function, you can use the vertical line test. The vertical line test states that if you can draw a vertical line that intersects the graph in more than one place, then the graph is not a function.
Determining whether a graph represents a function is an important concept in mathematics, especially in algebra and calculus. A function is a set of ordered pairs where each input is associated with exactly one output.
So, if you take a ruler or a straight edge and place it vertically on the graph, and it intersects the graph in two or more points, then the graph is not a function. This is because if two points in the graph have the same x-value, they must have different y-values, since functions can only have one output for each input.
On the other hand, if you place a vertical line anywhere on the graph and it intersects the graph in only one point, then the graph is a function.
It's also important to remember that a function must also pass the horizontal line test, which means that no horizontal line can intersect the graph in more than one place.

Using trigonometric relations we can write a system of equations, and solving that system we will get:
x = 3*√5
How to find the value of x?We can view this as two right triangles, one smaller (in the right) and other larger, made of the two small triangles.
Also notice that the vertice in the right side is common for the two triangles, then we can use trigonometric relations that call for that angle.
If that angle is θ, we can see that x is the hypotenuse and 5 is the adjacent cathetus, then we can write:
cos( θ) = 5/x
For the larger triangle, the hypotenuse is 4 + 5 = 9, and the adjacent cathetus is x, then we can write:
cos(θ) = x/9
So we have the system of equations:
cos( θ) = 5/x
cos(θ) = x/9
Using substitution we can write:
5/x = x/9
If we multiply both sides by x we get:
5 = x^2/9
Now we can multiply both sides by 9 to get:
5*9 = x^2
√(5*9) = x^2
3√5 = x

The profit-maximizing level of output derived in part e is validated using the MC and MR rule. And by following the steps below and performing the necessary calculations, the answers to parts a) to f) can be obtained for the given revenue and cost functions.
a) Using the revenue function \(TR = 100Q - 3Q^2\), Total Revenue (R) can be calculated by substituting different values of Q. Average Revenue (AR) is obtained by dividing Total Revenue by the corresponding quantity (Q). Marginal Revenue (MR) is calculated by finding the change in Total Revenue with respect to a one-unit change in quantity (Q).
b) With the cost function \(TC = 100 + 10Q + 2Q^2\), Total Cost (C) can be calculated by substituting different values of Q. Average Cost (AC) is obtained by dividing Total Cost by the corresponding quantity (Q). Marginal Cost (MC) is calculated by finding the change in Total Cost with respect to a one-unit change in quantity (Q).
c) The profit function (n) is constructed by subtracting Total Cost (C) from Total Revenue (R), resulting in \(n = R - C\).
d) Total profit is calculated by substituting different values of Q into the profit function (n) and calculating the difference between Total Revenue and Total Cost.
e) The output level at which the firm maximizes profits or minimizes losses can be determined by identifying the quantity (Q) where the difference between Total Revenue and Total Cost is maximized.
f) The profit-maximizing level of output derived in part e can be validated using the MC and MR rule, which states that profit is maximized when Marginal Cost (MC) is equal to Marginal Revenue (MR) at the chosen output level (Q). By comparing the calculated MC and MR values at the profit-maximizing output level, we can validate if the rule holds true.
