Question: Each sandwich takes 10 minutes to make which means in the 10 hour shift there will be a... Each sandwich takes 10 minutes to make which means in the 10 hour shift there will be a total of 60 sandwiches. The deli wants an efficient way to increase the sandwich output using the same five workers and 10 hour shift (Don't Factor Break in) to produce 75 because of the 25% increase due to the expansion of the deli. What would you do to make the the process more efficient? Where each sandwich would take 8 minutes to make instead of 10 minutes. Please answer the question throughly.
Answers
Extra people required is 50.
Each of the five workers should increase their efficiency to a rate of 15 sandwiches per 10 hour shift.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Question 1 :
Number of associates = 30
Number of direct workers = 30 - 2 = 28
You work 8 hours a day and 5 days a week with two 15 minutes break or 30 minutes break per day.
Direct rate = 150 units per hour
Number of working hours in a week with break = 8 × 5 = 40 hours per week Number of working hours in a week = 7.5 hours per day × 5 days a week
= 37.5 hours per week
Units that department produce in a 40 hour week = 37.5 × 150 = 5625 units
28 people produce 5625 units in a week
Let x people produce 10,000 + 5625 = 15,625 units in a week
Using proportion,
28 : 5625 = x : 15,625
28 / 5625 = x / 15,625
x = (28 × 15,625) / 5625 = 77.78 ≈ 78
Extra people required = 78 - 28 = 50
Question 2 :
Number of sandwiches made in 10 minutes = 1
Number of sandwiches made in 10 hours = 60
5 workers are there. one worker makes 60/5 = 12 sandwiches
But Deli want number of sandwiches in 10 hours = 75
One worker should make 75/5 = 15 sandwiches instead of 12.
Number of sandwiches made in 8 minutes should be 1.
So the working efficiency on each worker should be increased and produce each one should produce 15 sandwiches in a 10 hour shift.
Hence extra people required in question 1 is 50 and efficiency of each worker in question 2 should be increased to 15 sandwiches in 10 hours shift.

Find the solution of the following initial value problem. y ′′ + y = δ(t − 2π) cost; y(0) = 0, y′ (0) = 1
Answers
The solution of the given initial value problem is y(t) = sin(t) + H(t-2π)cos(t-2π), where H(t) is the Heaviside step function.
To solve the initial value problem, we start by finding the complementary solution, which satisfies the homogeneous differential equation y'' + y = 0. The complementary solution is given by y_c(t) = A sin(t) + B cos(t), where A and B are constants to be determined.
Next, we find the particular solution for the given non-homogeneous term δ(t-2π)cos(t). Since the forcing term is a Dirac delta function at t = 2π, we can write the particular solution as y_p(t) = K(t-2π)cos(t-2π), where K is a constant to be determined.
Applying the initial conditions y(0) = 0 and y'(0) = 1, we can solve for the constants A, B, and K. Plugging in these initial conditions into the general solution, we find A = 0, B = 1, and K = 1.
Therefore, the solution of the initial value problem is y(t) = sin(t) + H(t-2π)cos(t-2π), where H(t) is the Heaviside step function.
The initial value problem with the given conditions is solved by finding the complementary solution and the particular solution. The solution is y(t) = sin(t) + H(t-2π)cos(t-2π), where H(t) is the Heaviside step function. This solution satisfies the given initial conditions y(0) = 0 and y'(0) = 1.

evaluate the integral 6x(1 y^3)^1/2 da where r is the triangle enclosed by x=0, y=x, and y=1
Answers
Answer: The value of the integral is -1.
Step-by-step explanation:
We want to evaluate the integral : ∫∫r 6x√(1-y^3) dA
where r is the triangle enclosed by the x-axis, y-axis, and the line y = 1.
To set up the double integral, we need to determine the bounds of integration for x and y.
Since the triangle is enclosed by the x-axis, y-axis, and the line y = 1, we know that the bounds for y are from 0 to 1.
For x, we know that it varies between the y-axis and the line y = x, so the bounds for x are from 0 to y.
Therefore, we can set up the double integral as: ∫(y=0 to 1) ∫(x=0 to y) 6x√(1-y^3) dx dy
Now we integrate with respect to x: ∫(y=0 to 1) [3x^2√(1-y^3)]_0^y dy= ∫(y=0 to 1) 3y^2√(1-y^3) dy
At this point, we can make the substitution u = 1 - y^3, du = -3y^2 dy, which gives:= -∫(u=1 to 0) √u du
To integrate this expression, we make the substitution w = √u, dw = 1/(2√u) du, which gives:
= -2∫(w=1 to 0) w dw
= -[w^2]_1^0
= -1

If a right-angled triangle ha one traight line i 3x-1, and another traight line that i 3x, what i the are of the triangle
Answers
The area of the triangle formed by the two straight lines 3x-1 and 3x is 0 since both sides of the triangle have a length of 2/3.
A right-angled triangle is a type of triangle that has one angle that measures exactly 90 degrees.
In this scenario, we have two straight lines, one with the equation 3x-1 and another with the equation 3x.
To find the area of a right-angled triangle, we need to know the lengths of both of its sides.
Since we have the equations of the two straight lines that form the sides of the triangle, we can use these equations to find the length of each side.
The first side of the triangle can be found by finding the length of the line segment between the two points where the line 3x-1 intersects the x-axis. The x-axis is a horizontal line where the y-coordinate is 0.
Therefore, to find the two points of intersection, we set the y-coordinate of the line equal to 0 and solve for x.
=> 3x-1 = 0
=> 3x = 1
=> x = 1/3
So the two points of intersection are (1/3, 0) and (-1/3, 0). The length of the line segment between these two points can be found using the distance formula:
=> d = √((x₂ - x₁)² + (y₂ - y₁)²)
=> d = √((-1/3 - 1/3)² + (0 - 0)²)
=> d = √(-2/3)²
=> d = 2/3
So the length of the first side of the triangle is 2/3

The Fandago Bike Company specializes in children’s bikes. Each month, the company must keep track of their costs and revenue. Their costs consists of fixed costs that include rent, utilities, and workers’ salaries, as well as the variable cost to make the bikes. You can represent the company’s costs using the function C(x) = 25x + 900. You can represent the company’s revenue for every bike sold using the function R(x) = 100x - x².
Due to the rising costs of running a business, the Fandago Bike Company anticipates fixed costs in the next year to be $1800 per month, whereas the cost to make each bike will stay at $25 per bike.
Determine the number of bikes the company now needs to make for one month to break even when the revenue from selling bikes remains the same.
Answers
The Fandago Bike Company needs to produce 60 bikes in one month to break even when the revenue from selling bikes remains the same.
To find the number of bikes the Fandago Bike Company needs to make for one month to break even, we need to set the cost function equal to the revenue function and solve for x. This is because the break-even point is the point where the company’s revenue equals its costs.
The cost function is C(x) = 25x + 900, where x is the number of bikes produced in one month.
The revenue function is R(x) = 100x - x², where x is the number of bikes sold in one month (which we assume is equal to the number of bikes produced).
Setting C(x) = R(x), we have:
25x + 900 = 100x - x²
Rearranging and simplifying, we get a quadratic equation in standard form:
x² - 75x + 900 = 0
We can solve for x using the quadratic formula:
x =\((-b \± \sqrt(b\² - 4ac)) / 2a\)
In this case, a = 1, b = -75, and c = 900, so we have:
x = \((-(-75) \± \sqrt((-75)\² - 4(1)(900))) / 2(1)\)
Simplifying, we get:
x = (75 ± 45) / 2
x = 60 or x = 15
Since we are looking for the number of bikes the company needs to make to break even, we choose the value of x that represents the minimum number of bikes needed. In this case, x = 60, since the number of bikes produced cannot be negative.

Answers
The correct interpretation of an odds ratio of 0.75 would be (a) If not exposed the outcome is less likely since the odds ratio is less than 1.
An odds ratio of less than 1 indicates a decreased odds of the outcome in the exposed group compared to the unexposed group. Specifically, an odds ratio of 0.75 suggests that the odds of the outcome occurring in the exposed group is 25% lower than the odds of the outcome occurring in the unexposed group.
Option b is incorrect as an odds ratio of 0.75 is not necessarily close to 0, and option c is incorrect because an odds ratio of 0.75 means that the odds of the outcome in the exposed group is lower than the unexposed group, not 75 times greater. Option d is also incorrect as a protective effect would be observed if the odds ratio were less than 1.
Therefore, the correct option is (a) If not exposed the outcome is less likely since the odds ratio is less than 1.

Lotteries In a New York State daily lottery game, a sequence of two digits (not necessarily different) in the range 0-9 are selected at random. Find the probability that both are different.
Answers
The probability that both digits in a New York State daily lottery game are different is 0.9, or 9 out of 10.
To find the probability that both digits in a New York State daily lottery game are different, we need to first calculate the total number of possible outcomes. Since there are 10 digits (0-9) that can be selected for each of the two digits in the sequence, there are a total of 10 x 10 = 100 possible outcomes.
Now, we need to determine the number of outcomes where both digits are different. There are 10 possible choices for the first digit and only 9 possible choices for the second digit, since we cannot choose the same digit as the first. Therefore, there are a total of 10 x 9 = 90 outcomes where both digits are different.
The probability of both digits being different is equal to the number of outcomes where both digits are different divided by the total number of possible outcomes. Thus, the probability is 90/100, which simplifies to 9/10, or 0.9.
In summary, the probability that both digits in a New York State daily lottery game are different is 0.9, or 9 out of 10. This means that there is a high likelihood that both digits selected will be different.

Answers
When the cloud coverage was 4 percent or less, Glen Sarin took approximately 45 photographs.
Glen Sarin, the photographer, wonders if there is a correlation between the percentage of cloud cover and the number of photographs she captures. She maintains a record that is depicted in the scatterplot below.
When the cloud coverage was 4 percent or less, how many photographs did she take?We can observe that, as the percentage of cloud cover increases, the number of photographs taken by Glen Sarin decreases. As per the scatterplot,
This can be done by reading the point where the 4% line of cloud cover intersects with the line of best fit and drawing a line perpendicular to the x-axis to see what is the corresponding y-value (which represents the number of photographs)
This can be interpreted as follows: the scatterplot shows a negative correlation between the percentage of cloud cover and the number of photographs taken.
This indicates that as the percentage of cloud cover increases, the number of photographs taken decreases. Glen Sarin may use this information to make informed decisions about when and where to photograph.
