Answer:

If you click on the link you find a picture which has black dots on a white background. This suggests that we color every point on the plane either white or black, making sure to use infinitely many of each color. With these constraints it is indeed the case that there must be a black point and a white point at unit distance. (In fact, "infinite" can be weakened to nonempty.)

Step-by-step explanation:

Hint: starting with a black point, we're done unless the entire unit circle around that point is black. Now repeat that argument for each point on that unit circle: we've already generated a sizable swathe of the plane colored totally black...

Answer:

\(\frac{\partial f}{\partial x} = -70+7\cdot y\), \(\frac{\partial f}{\partial y} = 12+7\cdot x\), \(\frac{\partial f}{\partial x} (1,-1) = -77\), \(\frac{\partial f}{\partial y}(1,-1) = 19\)

Step-by-step explanation:

Let \(f(x,y) = 9000-70\cdot x +12\cdot y +7\cdot x \cdot y\), then the first partial derivatives of this multivariate function are, respectively:

\(\frac{\partial f}{\partial x} = -70+7\cdot y\) (1)

\(\frac{\partial f}{\partial y} = 12+7\cdot x\) (2)

Now we evaluate the partial derivatives at \((x,y) = (1, -1)\):

\(\frac{\partial f}{\partial x}(1,-1) = -70+ 7\cdot (-1)\)

\(\frac{\partial f}{\partial x} (1,-1) = -77\)

\(\frac{\partial f}{\partial y}(1,-1) = 12+7\cdot (1)\)

\(\frac{\partial f}{\partial y}(1,-1) = 19\)

Using the given percentage and solving an equation, we can see that 1/4 is the 80% of 0.3125

Let's define the variable x as the number, we know that the 80% of this number is 1/4.

Then we can write the equation:

1/4 = (80%/100%)*x

And we can try to use that equation ot find the value of x.

1/4 = 0.8*x

(1/4)/0.8 = x

0.3125 = x

Then we conclude that 1/4 is the 80% of 0.3125

Step-by-step explanation:

3²×(3³)² × 3^-8

(3³)² = 3⁶

remember that an exponent of an exponent means to multiply the 2 exponents.

3²×3⁶ = 3⁸

remember that when we multiply the same base number with exponents, we add these exponents.

and then 3⁸×3^‐8 = 3⁰ = 1

3²×(2×3)^-3 / (2^-3)

(2×3)^-3 = 2^-3 × 3^-3

remember that an exponent of a product means that that exponent has to be applied to every factor.

so, 2^-3 / 2^-3 = 1

that leaves us with 3²×3^-3

remember that we add the exponents in such a case.

2 + -3 = -1

so, we get 3^-1 = 1/3

remember that a negative exponent just means 1/...

2^-1 × (2×3)⁴ / (2×3)³

this is now easy.

(2×3)⁴ / (2×3)³ = (2×3)¹ = 2×3

and then

2^-1 × 2¹×3¹ = 2⁰×3¹ = 1×3 = 3

2⁵×3⁵×6^-5 = (2×3)⁵ × 6^-5 = 6⁵×6^-5 = 6⁰ = 1

2³×(2×3)^-1 / 2²

2³/2² = 2¹ = 2

2¹×(2×3)^-1 = 2¹×2^-1 × 3^-1 = 2⁰×3^-1 = 1×3^-1 = 3^-1 = 1/3

The mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)

Given data values are 55, 56, 70, 61, 53, 57, 50, 73, 52, 69, and 2. We need to calculate the mean, median, and mode of this sample.So, let's first arrange the data values in ascending order:2, 50, 52, 53, 55, 56, 57, 61, 69, 70, 73

Mean:The mean is the sum of all the data values divided by the total number of data values. So, we can use the following formula to calculate the mean:

Mean = (sum of all the data values) / (total number of data values)Sum of all the data values = 55 + 56 + 70 + 61 + 53 + 57 + 50 + 73 + 52 + 69 + 2 = 598Total number of data values = 11

Therefore,Mean = (sum of all the data values) / (total number of data values) = 598 / 11 = 54.36 (rounded to two decimal places)Therefore, the mean of the given data values is 54.36.

Median:The median is the middle value of a sorted data set. Since the data set has 11 data values, the median is the average of the 6th and 7th values (counting from smallest to largest).

Therefore, the median is :Median = (55 + 56) / 2 = 55.5Therefore, the median of the given data values is 55.5.

Mode:The mode is the data value that appears most frequently in the data set. In this case, there is no data value that appears more than once. So, there is no mode.

Therefore, the mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)

The value of angle x in decimal place is 57.8°.

A decimal number's digits are assigned a place value according to a chart that displays decimal place values. A digit in a number's place value is, as far as we are aware, its numerical value. The correct placement of each digit in a decimal number is therefore determined using decimal place value charts, just like with other place value diagrams. In this chart, the place values of the digits before and after the decimal point are shown.

Draw the altitude of the triangle

We know that

sinθ =  Opposite / Hypotenuse

sin 38° = y/11

Answer:

z ≥ − 8

Step-by-step explanation:

The formula to find the resolution of an image, also known as its pixel density, is Pixels per Inch (PPI) or Pixels per Centimeter (PPCM). This formula is used to determine the number of pixels in a given area of an image.

The higher the PPI or PPCM, the greater the resolution of the image.

To calculate PPI, you need to know the total number of pixels in the image (width x height) and the physical size of the image (width x height in inches or cm). Once you have this information, you can use the following formula: PPI = (pixels / physical size) x (inches/cm).

For example, if an image has a resolution of 1920 x 1080 pixels and is printed at a size of 8 x 6 inches, the PPI would be (1920 x 1080) / (8 x 6) = 240 PPI.

In conclusion, PPI or PPCM is the formula used to find the resolution of an image, also known as its pixel density. It is calculated by dividing the total number of pixels in the image by its physical size and multiplying it by inches/cm.

The higher the PPI or PPCM, the greater the resolution of the image. It is important to consider the PPI or PPCM when choosing an image to print or display in order to ensure that it will be of high quality and have a high resolution.

When in doubt, you can use your calculator to evaluate these expressions. If the decimal fraction uses all available digits, the number is likely irrational.

If the number cannot be expressed exactly without using symbols (√, ∛, π, e), then it is irrational. The attached calculator display shows this nicely.

The correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

To calculate the probability of a cash flow being between $16,000 and $19,000, we can use the standard deviation and assume a normal distribution.

We are given that the average cash flow is $14,000 with a standard deviation of $5,000. These values are necessary to calculate the probability.

The probability of a cash flow falling within a certain range can be determined by converting the values to z-scores, which represent the number of standard deviations away from the mean.

First, we calculate the z-score for $16,000 using the formula: z = (x - μ) / σ, where x is the cash flow value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get z1 = (16,000 - 14,000) / 5,000.

z1 = 2,000 / 5,000 = 0.4.

Next, we calculate the z-score for $19,000: z2 = (19,000 - 14,000) / 5,000.

z2 = 5,000 / 5,000 = 1.

Now that we have the z-scores, we can use a standard normal distribution table or calculator to find the corresponding probabilities.

Subtracting the probability corresponding to the lower z-score from the probability corresponding to the higher z-score will give us the probability of the cash flow falling between $16,000 and $19,000.

Looking up the z-scores in a standard normal distribution table or using a calculator, we find the probability for z1 is 0.6554 and the probability for z2 is 0.8413.

Therefore, the probability of the cash flow being between $16,000 and $19,000 is 0.8413 - 0.6554 = 0.1859, which is approximately 18.59%.

So, the correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

WE are given that integral of R(t) with respect to t ∫[0,5] R(t) dt = ∫[0,5] (30,000 + 3,000t) dt

To determine the total value of the income stream, we need to evaluate the definite integral of the function R(t) over the given interval. The integral of R(t) with respect to t is:

∫[0,5] R(t) dt = ∫[0,5] (30,000 + 3,000t) dt
