The solution to the equation 0.2(10 - 5c) = 5c - 16 is c = 3.

To solve the equation 0.2(10 - 5c) = 5c - 16, we will first distribute the 0.2 on the left side of the equation:

0.2 * 10 - 0.2 * 5c = 5c - 16

Simplifying further:

2 - 1c = 5c - 16

Next, we will group the variables on one side and the constants on the other side by adding c to both sides:

2 - 1c + c = 5c + c - 16

Simplifying:

2 = 6c - 16

To isolate the variable term, we will add 16 to both sides:

2 + 16 = 6c - 16 + 16

Simplifying:

18 = 6c

Finally, we will divide both sides by 6 to solve for c:

18/6 = 6c/6

Simplifying:

3 = c

Step-by-step explanation:

If you believe that bit plane slicing is lossy, then 1st-order extrapolation or 2D bilinear interpolation cannot fully recover the original image.

What is extrapolation and interpolation?

Extrapolation is an estimation based on extending a known sequence of data beyond what is absolutely known.

Interpolation is the estimation of a value in a sequence of values between two known values.

Bit plane slicing is a lossy compression technique, which means that some information from the original image is lost during the compression process. The purpose of bit plane slicing is to reduce the size of an image by removing less significant bits from each pixel. As a result, the quality of the image is reduced.

1st-order extrapolation and 2D bilinear interpolation are techniques used to estimate or predict missing or unknown values from a given set of data. These techniques can be used to enhance the quality of an image, but they cannot recover the original image in cases where information has been lost through compression or degradation. In other words, they can only improve the quality of the image to a certain extent, but they cannot restore it to its original state.

So, if you believe that bit plane slicing is lossy, then 1st-order extrapolation or 2D bilinear interpolation cannot fully recover the original image, although they may help to improve its quality to some extent.

Answer:

4 units

Step-by-step explanation:

according to question:

perimeter of square = 16 units

4a = 16

where a is the side length

a = 16/4

= 4 units

Step-by-step explanation:

that r = P/(2π) so A = π(P/(2π))2 = P2/(4π). Any positive area less than this is also possible. So in this problem the largest area possible is (16 in.)2/(4π) = 64/π sq.

Answer:

a = 16

b = 10

c = 19

d = 3

Step-by-step explanation:

For a, we know that 60 is 12+a+a+a, and to find what a is, we subtract 12 from 60, so that 48=3a, so 48 is a times 3. dividing 48 by 3 gives a=16

For b, we know that 60 is 4(b+5), dividing both sides by 4, 15=b+5. Subtracting 5 from both sides, b=10

For c, we know that a+b+c=3(b+5), or 16+10+c=45, subtracting 26 from each side, c=19

For d, we know that 3c+d=60, or (19*3)+d=60. simplifying, 57+d=60. subtraction 57 from each side gives d=3

The probability that the sample mean would be greater than 168 is approximately 93.4%.

To find the probability that the sample mean is greater than 168, we can use the Central Limit Theorem, which states that the sampling distribution of the sample mean approaches a normal distribution, regardless of the shape of the population, as the sample size increases.

Given that the population is normally distributed with a mean (μ) of 164 and a standard deviation (σ) of 18.65, and we have a sample size (n) of 50, we can calculate the standard error of the mean (SE) as:

SE = σ / √n

SE = 18.65 / √50 ≈ 2.639

Next, we calculate the z-score using the formula:

z = (sample mean - population mean) / SE

z = (168 - 164) / 2.639 ≈ 1.517

To find the probability that the sample mean is greater than 168, we need to find the area under the standard normal distribution curve to the right of the z-score of 1.517. This can be determined using a standard normal distribution table or a calculator.

From the standard normal distribution table or a calculator, we find that the probability associated with a z-score of 1.517 is approximately 0.934.

The probability that the sample mean would be greater than 168 is approximately 93.4% (rounded to the nearest tenth of a percent).

The sequence a_n = (n+4)! is increasing and unbounded.

1. Monotonicity: To determine if the sequence is increasing or decreasing, we can compare the terms of the sequence. Upon observation, as n increases, the terms (n+4)! become larger. Therefore, the sequence is increasing.

2. Boundedness: To determine if the sequence is bounded, we need to analyze whether there exists a finite upper or lower bound for the terms. In this case, the terms (n+4)! grow without bound as n increases. There is no finite number that can serve as an upper bound for the terms. Therefore, the sequence is unbounded.

        Calculate the midpoint of the given vertices:

        MidPoint = ( -5 + 5/2,  3 + 3/2 )

        MidPoint = ( 0, 3 )

        Distance = √( -5 -5 )^2 + ( 3 - 3 )^2

        Distance = √( -10 )^2  +  (0)^2

        Distance = √100

        Distance =  10

        Side Length =  10/√3

        Side Length = 10/1.7

        Side Length = 5.88

        Height = √3/2  *  Side Length

The teacher should use a sample size of 13 in order to achieve a standard deviation of the sampling distribution of that is half as big as when using a sample size of 50.

To determine the sample size the teacher should use in order to have a standard deviation of the sampling distribution of (sample mean) that is half as big as when using a sample size of 50.

Since the teacher initially planned to take an SRS (Simple Random Sample) of size 50, we can plug this value into the formula and solve for the new sample size:

Now, we can cross-multiply and solve for the new sample size:

2√(Sample size) = √50

Squaring both sides to eliminate the square root:

4 * Sample size = 50

Dividing both sides by 4:

Sample size = 12.5

Since the sample size must be a whole number, we round up to the nearest integer:

Sample size ≈ 13

Therefore, the teacher should use a sample size of 13 in order to achieve a standard deviation of the sampling distribution of that is half as big as when using a sample size of 50.

Answer:

Step-by-step explanation:

If the distance h, in feet, between the tennis ball and the ground, t seconds after it is thrown is given by h(t)=(-16t^2) +160t + 384, at maximum height the velocity of the tennis ball will be zero.

Velocity is the rate of change of displacement of a body. If the distance is modeled by the equation h(t)=(-16t^2) +160t + 384 then its velocity will be gotten by taking the derivative with respect to time as shown;

V = dh/dt = -32t+160

at maximum height;

0 = -32t+160

32t = 160

t = 160/32

t = 5seconds

This means that the tennis ball reaches the maximum after 5seconds.

Answer: x = 4; x = 5

Step-by-step explanation:

The directions specify to solve by factoring

x^2 - 9x + 20 = 0

To factor, find two numbers that add to -9 and multiply to 20

-5 and -4 work

-5 + (-4) = -9

-5 * -4 = 20

(x - 4)(x - 5) = 0

x = 4, x =5

Explanation:

The left-most point is at (-3,-2). The x coordinate is all we're concerned with here. The x coordinate for this point is x = -3. This is the smallest x value possible as an input. We cannot have x = -4 as that is nowhere on the blue curve.

So the domain is the set of real numbers x such that x is -4 or larger

In set builder notation, that would look like \(\{x|x\in\mathbb{R}, \ x \ge -3\}\)

Answer:

Step-by-step explanation:

The equation of the line that is perpendicular to the line 3y - 4x = 6 is: c. 4y + 3x = 8.

The lines that are perpendicular to each other have slope value of their equation, m, that are negative reciprocals of each other or the product of their slopes is equal to -1.

Given the line 3y - 4x = 6, rewrite the equation in slope-intercept form, y = mx + b, and determine the value of m:

3y = 4x + 6

Divide both sides by 3

3y/3 = 4x/3 + 6/3

y = 4/3x + 2

The slope (m) = 4/3.

The slope of the line that would be perpendicular to the line 3y - 4x = 6, will have a slope of -3/4, which is the negative reciprocal of 4/3.

Rewrite 4y + 3x = 8 in slope-intercept form:

4y = -3x + 8

4y/4 = -3/4x + 8/4

y = -3/4x + 2

The slope of 4y + 3x = 8 is -3/4.

Therefore, the perpendicular line is: c. 4y + 3x = 8.

If A and B are two independent events for which P(A) = 0.2 and P(B) = 0.6  then the  probabilities are:

a. P(A/B) = 0.2

b. P(BIA) = 0.6

c. P(A and B) = 0.12

d. P(A or B) = 0.68.

a. To find P(A/B), we need to determine the probability of event A occurring given that event B has already occurred. Since events A and B are independent, the occurrence of event B does not affect the probability of event A. Therefore, P(A/B) = P(A) = 0.2.

b. To find P(BIA), we need to determine the probability of event B occurring given that event A has already occurred. Again, since events A and B are independent, the occurrence of event A does not affect the probability of event B. Therefore, P(BIA) = P(B) = 0.6.

c. To find P(A and B), we multiply the probabilities of events A and B because they are independent:

P(A and B) = P(A) * P(B) = 0.2 * 0.6 = 0.12.

d. To find P(A or B), we need to determine the probability of either event A or event B (or both) occurring. Since events A and B are independent, we can use the addition rule:

P(A or B) = P(A) + P(B) - P(A and B) = 0.2 + 0.6 - 0.12 = 0.68.

Therefore, the probabilities are:

a. P(A/B) = 0.2

b. P(BIA) = 0.6

c. P(A and B) = 0.12

d. P(A or B) = 0.68.

The price per T-shirt should be at least $15 to achieve a profit of $250.

To calculate the price per T-shirt that will yield a profit of at least $250, we need to consider the cost of production, the desired profit, and the number of shirts to be sold.

Given that the cost to make each T-shirt is $10, and we want to sell 50 shirts, the total cost of production would be 10 * 50 = $500.

Now, let's calculate the minimum revenue needed to achieve a profit of $250. We add the desired profit to the total cost of production: $500 + $250 = $750.

Finally, to determine the price per T-shirt, we divide the total revenue by the number of shirts: $750 ÷ 50 = $15.

Therefore, to make a profit of at least $250, the price per T-shirt should be set at $15.

By selling each T-shirt for $15, the total revenue would be $15 * 50 = $750. From this revenue, we subtract the total production cost of $500 to calculate the profit, which amounts to $750 - $500 = $250. Thus, by charging $15 per T-shirt, the desired profit of $250 is achieved.
