The number of cases per batch that should be produced to minimize cost is: 300 units

The number of cases per batch that should be produced to minimize cost can be found by using the Economic Order Quantity.

The Economic Order Quantity (EOQ) is a calculation performed by a business that represents the ideal order size that allows the business to meet demand without overspending. The inventory manager calculates her EOQ to minimize storage costs and excess inventory.  

Thus:

Number of cases per batch = √((2 * Setup costs * annual demand)/ holding costs for the year)

Solving gives:

√((2 * 30 * 15000)/10)

= √90000

= 300 units

To determine the number of receptacles required for the bathroom counter space, we need to refer to the electrical code guidelines. The specific requirements may vary depending on the country or region, as well as the local electrical codes in place.

In the United States, according to the National Electrical Code (NEC), at least one 20-ampere-rated branch circuit is required to serve the bathroom receptacles. The code specifies that this circuit should be dedicated solely to the bathroom receptacles and should not serve any other areas.

The NEC also states that at least one receptacle outlet is required on the bathroom countertop. This receptacle should be located within 3 feet of the outer edge of the countertop and should be installed above the countertop surface. This means that a receptacle needs to be placed within reach of the bathroom counter space.

Considering the given information that the bathroom counter space is seven feet, including the sink, we need to install at least one receptacle outlet on the countertop within 3 feet of the outer edge. Depending on the specific layout and size of the counter space, additional receptacles may be required to meet the code's requirements for accessibility and convenience.

To ensure compliance with local electrical codes and safety standards, it is advisable to consult with a licensed electrician or refer to the specific electrical codes applicable in your area. They will be able to provide accurate guidance based on the local requirements and regulations.

According to the Pythagorean Theorem, a right triangle's hypotenuse (the side opposite the right angle) or, using conventional algebraic notation,\(a^{2} + b^{2} = c^{2}\)

The Greeks established the existence of numbers that could not be expressed as rational numbers thanks to Pythagoras' theorem. For instance, if we assume that the two shorter sides of a right triangle are 1 and 1, we are left with a length hypotenuse that is not a rational number.

By Pythagoras theorem-

\(adjacent side^{2} + opposite side^{2} = hypotenuse^{2}\)

35= opposite side

r= adjacent side

25+r= hypotenuse

\((25+r)^{2} = 35^{2} + r^{2}\\ 665 + r^{2} + 50r = 1225 + r^{2} \\50r = 600\\r=12 units\)

One possible transformation is a reflection in the x-axis followed by a dilation centered at the origin with a scale factor of 3.

A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.

Before the dilation, the figure was reflected from the first quadrant to the second quadrant, which is a lateral reflection, hence the figure was reflected over the x-axis.

The height of the blue triangle is of 1 unit, while the height of the larger triangle is of 3 units, hence the scale factor is given as follows:

The variance of the given returns is approximately 0.1475. The variance measures the dispersion or variability of the returns from the mean return.

To calculate the variance, we need to follow a few steps:

Calculate the mean (average) return:

Mean = (Year 1 + Year 2 + Year 3 + Year 4) / 4

= (16% + 6% + (-25%) + (-3%)) / 4

= -6% / 4

= -1.5%

Calculate the squared deviations from the mean for each year:

Deviation from mean for Year 1 = 16% - (-1.5%) = 17.5%

Deviation from mean for Year 2 = 6% - (-1.5%) = 7.5%

Deviation from mean for Year 3 = -25% - (-1.5%) = -23.5%

Deviation from mean for Year 4 = -3% - (-1.5%) = -1.5%

Square each deviation:

Squared deviation for Year 1 = (17.5%)^2 = 0.0306

Squared deviation for Year 2 = (7.5%)^2 = 0.0056

Squared deviation for Year 3 = (-23.5%)^2 = 0.5525

Squared deviation for Year 4 = (-1.5%)^2 = 0.000225

Calculate the average of the squared deviations:

Variance = (0.0306 + 0.0056 + 0.5525 + 0.000225) / 4

= 0.589925 / 4

Tyler charges $8 for an adult ticket.

It is given that Tyler charges $t for adult tickets and $5 for child tickets.

No. of tickets sold by him on Monday is 12 child tickets and 9 adult tickets.

No. of tickets sold by him on Tuesday is 20 child tickets and 4 adult tickets.

Therefore,

Tyler earned $12 X 5 + $9 X t on Monday

= $9t + $60

Tyler earned $20 X 5 + $4 X t on Tuesday

= $4t + $100

According to the problem, the earnings on both the days are same. Hence we get the linear equation as follows

9t + 60 =  4t + 100

bringing all the variables, i.e t's to LHS and constants to RHS we get

9t - 4t = 100 - 60

or, 5t = 40

Bringing 5 to RHS we get

t = 40/5

or, t = 8

Therefore, t = $8

What is graph?

A graph is a structure that resembles a set of items in discrete mathematics, more especially in graph theory, in which certain pairs of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Graphs are a popular tool for graphically illuminating data connections. A graph serves the objective of presenting facts that are either too many or complex to be fully expressed in the text while taking up less room.

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.

There are no vectors among the options provided that are parallel to (1²2).

To determine if two vectors are parallel, we can compare their direction ratios.

Two vectors are parallel if their direction ratios are proportional.

Let's compare the given vector (1²2) with each of the options provided:

Vector (7²) (12²) (-22) (3) 12/ (ő) 4 24 3 13/​:

Comparing the direction ratios, we have:

1/7 = 2/12 = 2/-22 = 3/4 = 24/3 = 12/13.

Since the direction ratios of the given vector (1²2) are not proportional to the direction ratios of any of the options, none of the options are parallel to (1²2).

Compared to the average daily temperature in August, the average temperature in December dropped by 50%.

The difference between two numbers can be expressed as a percentage of the original value using the term "percentage change." To track changes in factors like prices, sales, and economic growth, it is frequently used in business, finance, and economics.

To calculate the percent change between two values, we use the formula:

Percent change = [(new value - old value) / old value] x 100%

The old value in this case represents the typical daily temperature for August, whereas the new value represents the typical daily temperature for December.

Percent change = [(37 - 74) / 74] x 100%

Percent change = (-37 / 74) x 100%

Percent change = -0.5 x 100%

Percent change = -50%

Therefore, the average daily temperature in December decreased by 50% compared to the average daily temperature in August.

Answer:

The Great Chicago Fire was a conflagration that burned in the American city of Chicago during October 8–10, 1871. The fire killed approximately 300 people, destroyed roughly 3.3 square miles (9 km 2) of the city, and left more than 100,000 residents homeless. The fire began in a neighborhood southwest of the city center.

Step-by-step explanation:

Origin

The fire is claimed to have started at about 8:30 p.m. on October 8, in or around a small barn belonging to the O'Leary family that bordered the alley behind 137 DeKoven Street.

Spread

When firefighters finally arrived at DeKoven Street, the fire had grown and spread to neighboring buildings and was progressing toward the central business district.

Aftermath

Once the fire had ended, the smoldering remains were still too hot for a survey of the damage to be completed for many days. Eventually, the city determined that the fire destroyed an area about 4 miles (6 km) long and averaging ⁄4 miles (1 km) wide, encompassing an area of more than 2,000 acres (809 ha).
