Dominoes refers to a group of tile-based games with playing pieces that resemble dominoes. A line usually divides the two square ends of each rectangular domino tile. Either a blank space or a series of dots designate each end. Each tile in a set has a back that is either blank or has a similar design, making them all identical.
The playing pieces are what make up a domino set, sometimes referred to as a deck or pack. The typical European domino set consists of 28 tiles with spot counts ranging from zero to six in all possible combinations. Some other names for these tiles are pieces, bones, rocks, stones, men, cards, and simply dominoes.

In an experiment with probability function f(x) is binomially distributed with probability p that an attribute occurs at a single trial. If in four trials of the experiment, the attribute occurs four times with probability 16/81, find the value of p
Answer:
Step-by-step explanation:
A binomial probability function has two parameters: n, the number of trials and p, the probability of success (or occurrence of the attribute) in a single trial.
In this case, we are given that the attribute occurs four times in four trials, with probability 16/81. Using this information, we can use the binomial probability formula to find the value of p:
P(k) = (n choose k) * p^k * (1-p)^(n-k)
Where k is the number of successes in n trials, and (n choose k) is the binomial coefficient, which is the number of ways to choose k items from n items without replacement.
In this case,
k = 4 (the attribute occurs four times)
n = 4 (there are four trials)
P(k) = 16/81
We can use this equation to find the value of p:
(4 choose 4) * p^4 * (1-p)^(4-4) = 16/81
1 * p^4 * (1-p)^0 = 16/81
p^4 = 16/81
p = √(16/81)
p = √(4/81)
p = √(1/81)
p = 1/9
The value of p is 1/9
This means that in a single trial of the experiment, the probability of the attribute occurring is 1/9 or about 0.111

The area of a rectangle is represented by 32X exponent three it’s a length of a rectangle is 4X then the width is 
Answer:We know that the area of a rectangle is represented by the product of its length and width, so the equation for the area of the rectangle is:
A = l * w
We also know that the area of the rectangle is given as 32X^3 and the length of the rectangle is 4X. Therefore, we can substitute these values into the equation:
32X^3 = (4X) * w
To find the width of the rectangle, we can divide both sides of the equation by 4X:
w = 32X^3 / 4X
Simplifying the equation, we can get the value of w:
w = 8X^2
So the width of the rectangle is 8X^2

Work out the area of a rectangle with base,
b
= 26mm and perimeter,
P
= 68mm.
Please help me
Answer:
208 mm
Step-by-step explanation:
A = Area. P = Perimeter. B = base.
Let's say H = Height
P = 2B + 2H
Now we already know the perimeter is 68 mm, so P = 68:
68 = 2B + 2H
In addition, we know that the base is 26 mm, so B = 26:
68 = 2(26) + 2H
68 = 52 + 2H
16 = 2H ==> subtract 52 on both sides
H = 8 ==> the height of the rectangle is 8 mm
A = B * H
A = 26 * 8 ==> plugin B=26 and H=8 into the Area formula
A = 208 ==> simplified
Hence, the area is 208 mm.
if it takes 42 minutes to load 3 1/2 trucks, how many minutes will it take to load 6 1/2 trucks? 36 78 84 96 backnext
The information provided indicates that it will take 78 minutes to load.
How are math and time related?Time may be described in mathematics as a continuing and continuous series of events that take place one after another, from the past through the present, and into the future. The length of events or the gaps between them may be measured, compared, or even ordered using time.
If loading three and a half trucks takes 42 minutes, loading one truck will take 42 / 3.5 minutes, or 12 minutes. The time needed to load is calculated by multiplying the minutes per vehicle by 6.5. In this scenario, it would take 78 minutes to load 6 1/2 trucks (12 x 6.5). The time taken is calculated using the formula t = 12n, where n indicates the number of trucks and t is the time in minutes.

antti entered a 10 kilometer race. his goal is to finish in one hour. he starts off sprinting, and completes the first 2 kilometers of the race at an average speed of 12 kilometers per hour. to achieve his goal of a one-hour finish time, what average speed must antti maintain for the last 8 kilometers of the race?
So, Antti must maintain an average speed of 8 kilometers per hour for the last 8 kilometers of the race in order to finish in one hour.
To finish the 10 kilometer race in one hour, Antti must maintain an average speed of 10 kilometers per hour for the entire race. Since he has already completed 2 kilometers at an average speed of 12 kilometers per hour, he must make up for that extra speed by running the last 8 kilometers at a slower pace.
To find out what average speed he must maintain for the last 8 kilometers to finish in one hour, we can use the formula:
(distance) / (time) = (speed)
So, 8 / 1 = 8 kilometers per hour
Antti must maintain an average speed of 8 kilometers per hour for the last 8 kilometers of the race in order to finish in one hour.

Assuming that the y-axis tick marks will be separated by 50 (50, 100, 150, and so on), what is the largest value that should appear on the y-axis?
Assuming that the y-axis tick marks will be separated by 50 (50, 100, 150, and so on). The largest value that should appear on the y-axis is 400.
Largest value:
The maximum value of a dataset is often called the maximum value (max for short), and the minimum value is often called the minimum value (or min). The difference between the maximum and minimum values, sometimes called the range, is calculated by subtracting the minimum value from the maximum value.
Dependent and Independent Variables for ChartResearchers varied the time of the experiment to measure the activity of the enzyme on glucose-6-phosphate (substrate). This happened because the enzyme acted on glucose-6-phosphate to produce glucose and a phosphate ion (Pi).
The concentration of phosphate ions was measured in the experiment. Therefore, time is the independent variable plotted on the x-axis and phosphate ion concentration is the dependent variable plotted on the y-axis.
The measured phosphate ion concentration ranges from 0 to 355. The maximum possible value is 355, so the y-axis range must be between 0 and 400. So the maximum value on the y-axis is 400.

0.80 is the expected value of wei's ticket. This can be solved by using the concept of probability.
What is probability?The word "probability" derives from the Latin word "probitatem," which means "credibility, likelihood," from the noun probabilis in the 14th century (see probable). The phrase was first used in a mathematical meaning in 1718.
A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
As, we know
E(x) = x₁. p(x₁) + x₂ . p(x₂) + ....... + x(n). p(x(n))
From the table it is shown that,
E(x) = (68% × 0) + (24% × 0) + (6% × 5) + (2% × 25)

does this approximate a normal distribution? does this confirm the first part of the central limit theorem?
No, this does not approximate a normal distribution.
This does not confirm the first part of the Central Limit Theorem, which states that the sum of a large number of independent random variables will approximate a normal distribution. To calculate the probability of a normal distribution, we need to calculate the mean and standard deviation of the sample. We can then use this information to calculate the z-score of a given value in the sample. The z-score will tell us how many standard deviations away from the mean a certain value is. If the z-score follows a normal distribution then the sample approximates a normal distribution. However, if the z-score does not follow a normal distribution then the sample does not approximate a normal distribution.

The probability of a senior student taking statistics or calculus is 0.82. This is calculated by adding the probability of a senior student taking statistics (0.15) and a senior student taking calculus (0.35).
p(a or b) = p(a) + p(b) - p(a and b)
p(a) = 15/100 = 0.15
p(b) = 35/100 = 0.35
p(a and b) = 15/100 = 0.15
p(a or b) = 0.15 + 0.35 - 0.15 = 0.82
The probability of a senior student taking either statistics or calculus is 0.82. This is calculated by adding the probability of a senior student taking statistics (0.15) and a senior student taking calculus (0.35) and subtracting the probability of a senior student taking both statistics and calculus (0.15).

Area of concave hexagon = 24
To find the area of the concave hexagon, we can divide it into two triangles and a rectangle. The side lengths of the rectangle are the difference of the radii of the two circles (4-2=2) and the distance between the centers of the circles, which can be found using the Pythagorean theorem. Using that we can find the area of the rectangle and the two triangles. The area of the hexagon is the sum of the areas of these three shapes.
In the given case, let the distance between the centers of the circles be 'd'.
d^2 = (4+2)^2
d = √((4+2)^2) = √(36) = 6
Area of rectangle = 26 = 12
