The probability of exactly one processor having no jobs is 4/9 when a computing center has 3 processors that receive n jobs.
The probability that exactly one processor has no jobs can be calculated using the binomial distribution. The number of successful trials (having exactly one processor with no jobs) is denoted by k and the total number of trials (number of ways to assign n jobs to 3 processors) is denoted by n. The probability of success in each trial is 1/3 (the chance that a particular processor has no jobs) and the probability of failure is 2/3 (the chance that a particular processor has one or more jobs).
Using the formula for binomial distribution, the probability that exactly one processor has no jobs can be calculated as follows:
[tex]P(X = k) = (n choose k) * (1/3)^k * (2/3)^{(n-k)}[/tex]
where (n choose k) is the number of combinations of n items taken k at a time, and can be calculated as n! / (k! * (n-k)!).
For the given scenario, n = 3 and k = 1, so the probability of exactly one processor having no jobs is:
[tex]P(X = 1) = (3 choose 1) * (1/3) * (2/3)^2 = 3 * (1/3) * (4/9) = 4/9.[/tex]
Hence, the probability of exactly one processor having no jobs is 4/9.

Shawn walks 5 miles in a southeast direction from his house. He stops for lunch then walks 6 miles in a northeast direction from his lunch spot. What is the shortest distance Shawn can walk to return home.
Shortest distance to reach home = 7.81 miles
What is Pythagoras theorem?Pythagoras theorem states that "In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides".
Given, Shawn walks 5miles in southeast from his house.
After having lunch he walks 6 miles north east.
Angle between both directions is 90°.
By the figure
AB = 5miles
BC = 6 miles
Shortest distance to return home is AC
By Pythagoras theorem
AC² = AB² + BC²
= 5² + 6²
AC² = 25 + 36
AC² = 61
AC = √61
AC = 7.81 miles.
Hence, 7.81 miles is the shortest distance to reach home.

3.3 3.3 pounds of apples at the total cost of $18.15 $ 18.15 . if she purchases 7.9 7.9 pounds of apples at this store, how much would it cost?
The unit cost of apples is found to be $5.5 per pound. So the cost of 7.9 pounds of apple will be 43.45.
Here we have to calculate the value of a pound of apple from the given data, and then should multiply the unit value to find the cost of the given weight.
Weight of apple that was purchased = 3.3 lbs.
Cost of 3.3 lbs. of apples = 18.15
Cost of a pound of apple = Cost of apples purchased/ weight of apples purchased
= 18.15/3.3 = 5.5.
So each pound of apple will cost $5.50.
Weight of apple to be purchased = 7.9 lbs.
Cost of the apples = Weight of apples × unit price
= 7.9 × 5.50 = 43.45.
So the cost of 7.9 pounds of apple will be $43.45.

What is the distance between two points of a line?The distance between two points of a line is given as:
Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
We have,
The coordinates of the endpoints are (a, b) = [tex](x_1, y_1)[/tex] and (-3, -5) = [tex](x_2, y_x)[/tex].
The distance between the two endpoints is 11 units.
Now,
Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
11 = [tex]\sqrt{(-3 - a)^2 + (-5 - b)^2}[/tex]
Squaring both sides.
11² = (-3 - a)² + (-5 - b)²
121 = (-3 - a)² + (-5 - b)²
If we take a = -3 and b = 6
121 = (-3 + 3)² + (-5 - 6)²
121 = 0 + (-11)²
121 = 121
or
If we take a = 8 and b = -5
121 = (-3 - 8)² + (-5 + 5)²
121 = (-11)² + 0
121 = 121
Thus,
(-3, 6) and (8, -5) are the possible endpoints.

The radius of the prize wheel is approximately 9.06 feet.
The circle's circumference (or perimeter) = 2πR, where R is the radius of the circle. 3.14 is the approximate value of π(up to two decimal points) value of the mathematical constant.
Again, Pi (π) is a particular mathematical constant that represents the circumference to diameter ratio of any circle.
The formula for the circumference of a circle is:
C = 2 * π * r
Where "C" is the circumference, "π" is pi (approximately equal to 3.14159), and "r" is the radius.
We can rearrange this formula to solve for the radius:
r = C / (2 * π)
Plugging in the given values:
r = 56.52 / (2 * 3.14159)

When a relation is displayed in each table row represents an ordered pair with the x column representing the input values and the y column representing the output values.
True or False?
True.
In a relation, each row of a table represents an ordered pair where the x-value is in the left column (also called the domain) and the y-value is in the right column (also called the range or codomain). The x-values represent the inputs to the relation, and the y-values represent the corresponding outputs.
Relation Table RepresentationA relation is a set of ordered pairs, where the first element of each pair comes from a set called the domain and the second element comes from a set called the range or codomain. In a table representing a relation, each row represents an ordered pair where the first element (the x-value) is from the domain and the second element (the y-value) is from the range or codomain.
For example, consider the relation R = {(1, 3), (2, 5), (3, 7)}. In a table representing R, the x column represents the first element of each ordered pair (i.e., the domain) and the y column represents the second element of each ordered pair (i.e., the range or codomain).
The first row of the table would be (1, 3), where 1 is the input (x-value) and 3 is the output (y-value) for the relation R. The second row of the table would be (2, 5), where 2 is the input (x-value) and 5 is the output (y-value) for the relation R. And so on for the rest of the rows in the table.
Therefore, each row of a table representing a relation does indeed represent an ordered pair, where the x column represents the input values and the y column represents the output values.

What is Arithmetic Progression?An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the arithmetic sequence be represented as A
Now , the equation will be
A = 14 , 22 , 30 , 38 ...
Now , the common difference of the AP is d = 8

how many strawberries should be picked so that the probability of having exactly 2 rotten strawberries among them equals 2/35
The final answer will depend on the specific value of p.
Let's say we need to choose a number of strawberries. Then, using the binomial distribution formula, it is possible to determine the likelihood that there will be exactly 2 rotting strawberries among them:
P(exactly two spoiled strawberries) i= (n choose 2) * p^2 * (1-p)^(n-2)
where p is the probability of each strawberry being rotten.
By setting this to 2/35 and figuring out n, we get at:
2/35 = (n choose 2) * p^2 * (1-p)^(n-2)
2/35 = (n choose 2) * p^2 * (1-p)^(n-2)
(2/35) / p^2 = (n choose 2) * (1-p)^(n-2)
It should be noted that p's value is unknown and would need to be determined by estimation or historical data. The final answer will depend on the specific value of p.

34/10
36/11
How much revenue will be produced for 45 units?
Answer: 12$
Step-by-step explanation: To find the revenue produced for 45 units, we need to find the equation that represents the relationship between the number of units sold (u) and the revenue produced (r). Based on the information given in the table, we can see that the revenue increases as the number of units sold increases. So, we can assume that there is a direct proportion between the number of units sold and the revenue produced. Therefore, we can use the equation: r = ku, where k is the constant of proportionality.
We can use any two of the given pairs (u, r) to find k. For example, using (30, 8), we have:
8 = k * 30
k = 8 / 30 = 4/15
So, the equation representing the relationship between the number of units sold and the revenue produced is: r = 4/15 * u. To find the revenue produced for 45 units, we can plug in u = 45 into the equation:
r = 4/15 * 45 = 12.
Therefore, the revenue produced for 45 units is $12.
