A store sells mugs Each mugs cost the same amount. During a sale the store reduces of each mug by $1. 75 Wen spends $28. 20 on 5 mugs at the sale price what was the price of one mug before the sale

Answer:5/8 fraction of the deposit has been spent, which is 20 liters

Let "a" be the initial amount of water, then first half the water is used: then a / 2 of water is used and the other half is left at / 2 * (1/4), then the fourth part is used: then 1/8 * a is used, so now it remains: a / 2 - a / 8 = 3/8 * a, so 5/8 * a has been used, then what remains are 12 liters:

3/8 * a = 12 L

a = 12 L * 8/3 = 32 L

Wasted: 32 L - 12 L = 20 L

ab = (x - 3)(x + 3)

multiply

ab = x² + 3x - 3x - 9

Simplify

ab = x² - 9

---------------------------

2ab = 2(x² - 9)

Distribute

2ab = 2x² - 18

Step-by-step explanation:

she painted half of the still to be painted area.

after the first weekend there were 800 of 1600 ft² painted, and therefore 1600 - 800 = 800 ft² left to be painted.

on the second weekend she then painted half of that :

800 / 2.

that means she painted 800/2 = 400 ft², and that left 800 - 400 = 400 ft² to be painted on the following weekends.

if we look in detail, we find the starting 800 ft² of the second weekend are already the result of the first weekend.

800 = 1600 / 2

so,

800 / 2 = 1600 / 2 / 2 = 1600 / 2² = 1600 / 4.

and the same principle goes on weekend after weekend.

therefore, the expression for the nth weekend could be

1600 × (1/2)^n ft²

that means, she painted

on the 1st weekend : 1600 × 1/2 = 800 ft²

on the 2nd weekend : 1600 × 1/4 = 400 ft²

on the 3rd weekend : 1600 × 1/8 = 200 ft²

on the 4th weekend : 1600 × 1/16 = 100 ft²

...

that also means : she will never be finished, as she always paints only half of what is still left open, and that leaves always some part open. it will be tinier and tinier over time, but never 0.

The maximum height of the coin is approximately 14.825 meters.

To find the maximum height of the coin, we need to find the vertex of the parabolic function. The x-coordinate of the vertex is given by:

x = -b/2a

where a = -5 and b = 13 are the coefficients of the quadratic function f(x) = -5x^2 + 13x + 6.

Plugging these values into the formula, we get:

x = -13/(2×(-5)) = 13/10

Now we can find the y-coordinate of the vertex by plugging in x = 13/10 into the function:

f(13/10) = -5(13/10)^2 + 13(13/10) + 6

Do the arithmetic operations

The ratio of dividends to the average number of common shares outstanding is known as the dividend yield. It is a measure of the return on an investment in the form of dividends received relative to the number of shares held.

To calculate the dividend yield, you need to divide the annual dividends per share by the average number of common shares outstanding during a specific period. The annual dividends per share can be obtained by dividing the total dividends paid by the number of outstanding shares. The average number of common shares outstanding can be calculated by adding the beginning and ending shares outstanding and dividing by 2.

For example, let's say a company paid total dividends of $10,000 and had 1,000 common shares outstanding at the beginning of the year and 1,500 shares at the end. The average number of common shares outstanding would be (1,000 + 1,500) / 2 = 1,250. If the annual dividends per share is $2, the dividend yield would be $2 / 1,250 = 0.0016 or 0.16%.

In summary, the ratio of dividends to the average number of common shares outstanding is the dividend yield, which measures the return on an investment in terms of dividends received per share held.

Answer:

\(y=3x+1\)

Step-by-step explanation:

Given the following question:

Point A = (0, 1) = (x1, y1)
Point B = (-2, -5) = (x2, y2)

In order to find the answer, we must first find the slope of the two given points by using rise over run.

\(m=\frac{y2-y1}{x2-x1}\)
\(m=\frac{-5-1}{-2-0}\)
\(m=\frac{-5-1}{-2-0} =\frac{-6}{-2}\)
\(=\frac{-6}{-2} =-6\div-2=3\)
\(m=3\)

Now that we know the slope, we can now write the equation in slope intercept form.

\(y=mx+b\)
\(m=3\)
\(y=1\)
\(x=0\)

Substitute:

\(1=3(0)+b\)
\(3\times0=0\)
\(1=b\)
\(b=1\)
\(y=3x+1\)

If the manufacturer sells 100 cameras,  the expected refunds to be paid is $16,655(A).

To calculate the expected refund amount, we need to consider the probabilities of the camera failing during each year and the corresponding refund amounts.

The probability of the camera failing during the first year is given by P(X ≤ 1) = ∫[0, 1] f(x) dx = 1 - e^(-1/3) ≈ 0.2835.

The probability of the camera failing during the second year (but not the first year) is given by P(1 < X ≤ 2) = ∫[1, 2] f(x) dx = e^(-1/3) - e^(-2/3) ≈ 0.2027.

Since the manufacturer sells 100 cameras, the expected refund amount can be calculated as:

Expected refund amount = (100 cameras) × (0.2835 × $500 + 0.2027 × $250) = $16,944.50.

Hence, the correct answer is A. $16,655.

Therefore, there are 4 vertices in this graph.

Let V be the number of vertices in the graph. The sum of the degrees of all vertices in an undirected graph is twice the number of edges, so in this case, the sum of degrees is 2 * 10 = 20.

We know that two vertices have degree 4, so the degrees of the remaining vertices must add up to 20 - 2 * 4 = 12.

If there are v vertices of degree 3, then the total degree contributed by those vertices is 3v, so we have:

3v + 2 * 4 = 20

3v = 12

v = 4

The vertex of the absolute value function is (-3, 2) and the range is y ≥ 2

For a general absolute value function:

y = |a*x + b| + d

The vertex is at the value of x such that the argument of the absolute value part becomes zero, this is at:

a*x + b = 0

x = -b/a

And the y-value of the vertex is c

In our case:

y = |2x + 6| + 2

The vertex is at:

x = -6/2 = -3

y = 2

So we can write it as (-3, 2)

Debris flow refers to a type of fast-moving landslide or mass movement that involves a mixture of water, soil, rocks, and other debris. It typically occurs in mountainous or hilly regions, especially after heavy rainfall or during periods of intense snowmelt.

The characteristics of debris flow include high velocity, thick consistency, and destructive power. They often exhibit a turbulent, surging flow pattern and can transport large volumes of material downstream. Debris flows have the ability to erode and carry away sediment, rocks, and vegetation, causing significant damage to infrastructure, property, and natural environments.

To monitor and reduce the risk of a stream with potential debris flow, various measures can be implemented. Monitoring techniques may include the installation of gauges and sensors to measure rainfall, water levels, and ground movement. Early warning systems can be established to alert residents and authorities of potential debris flow events.

To reduce the risk, structural measures such as the construction of debris flow barriers or channels can be implemented to divert or contain the flow. Land-use planning and zoning regulations can help restrict development in high-risk areas.

The probability distribution for the random variable f, the number landing face up when the die is tossed, is a discrete uniform distribution. The mean and standard deviation of this distribution are given as 3.5 and 1.7078, respectively.

When the die is tossed 5 times and the mean of the 5 values landing face up is recorded, this is referred to as a sample mean. The sample mean of 5 tosses of a die is also a random variable and its distribution is called the sampling distribution of the sample mean.

The simulation with 400 trials that you described is designed to estimate the sampling distribution of the sample mean. This can be done by repeating the process of tossing the die 5 times, finding the mean of the 5 values, and recording the result, 400 times. By collecting the sample mean values over 400 trials, it will give an idea of the distribution of the sample mean.

It's worth noting that as the sample size increases, the sampling distribution of the sample mean becomes closer to a normal distribution, known as the central limit theorem. And the mean of the sampling distribution becomes equal to the mean of the original distribution and the standard deviation of the sampling distribution becomes smaller.
