Given: 100,000 subscribers increases by 2.4% per month
To find: After a year, how much will that be?
First step:
Find the increase of the subscribers per month
100,000 of 2.4%
Set up an equation
2.4/100 × 100,000/1
Cross multiply, cancel zeros in both 100,000 and 100. Which is equal to:
2.4/1 x 1,000/1 =
2,400
Second step: If it increases per month,
then to find the year, find out how many months is in a year:
12 months = 1 year
Now that has been figured out, multiply the result by the result in the first step:
12 × 2400 = 28.800
Therefore, the number of subscribers will be after a year
suppose the relative risk of an outcome given exposure versus non-exposure is unity. determine the percent increased risk rounded to the nearest hundredth of a percent.
The percentage of higher risk is unaffected by exposure as relative risk in unity.
In order to determine the strength of the relationship between exposures (treatments or risk factors) and outcomes, relative risk is employed in the statistical analysis of data from ecological, cohort, medical, and intervention studies. For instance, in a study looking at how the drug apixaban affected the occurrence of thromboembolism, 8.8% of patients receiving a placebo developed the condition, whereas only 1.7% of patients receiving the medication did. This means that the relative risk is.19 (1.7/8.8), meaning that patients receiving apixaban had 19% the disease risk of patients receiving a placebo. [4] In this instance, apixaban lowers the probability of disease, making it a protective rather than a risk factor.
Values of relative risk can be understood as long as the relationship between the exposure and the result is assumed to be causal.
RR = 1 denotes that the outcome is unaffected by exposure.
When the risk of the outcome is less than 1, this is referred to as a "protective factor."
RR > 1 indicates that the exposure, a "risk factor," has an effect on the outcome's risk.
Therefore, the percentage of higher risk is unaffected by exposure as relative risk in unity.

1. The solution to the quadratic equation, x² - 14x + 49 = 40, is x = 13.32 and x = 0.68
2. The solution to the quadratic equation, x² - x = 12, is x = -3 and x = 4
3. i. The factors of 2x² - 15x - 8 = 0 are (2x +1) and (x - 8)
ii. The x-intercepts of 2x² - 15x - 8 = 0 are x = -1/2 and x = 8
Solving Quadratic equationsFrom the question, we are to solve the given quadratic equation by completing the square.
The given equation is
x² - 14x + 49 = 40
Solving the equation
x² - 14x + 49 = 40
x² - 14x = 40 - 49
x² - 14x = -9
Multiply the coefficient of x by 1/2 square and add to both sides
x² - 14x + (-7)² = -9 + (-7)²
(x - 7)² = -9 + 49
(x - 7)² = 40
x - 7 = ±√40
x = 7 ± √40
x = 7 ± 6.32
x = 7 + 6.32 OR 7 - 6.32
x = 13.32 OR 0.68
Solving x² - x = 12 by factoring
x² - x = 12
x² - x - 12 = 0
x² -4x + 3x - 12 = 0
x(x - 4) + 3(x - 4) = 0
(x + 3)(x - 4) = 0
x + 3 = 0 OR x - 4 = 0
x = -3 OR x = 4
Determining the factors of 2x² - 15x - 8 = 0
2x² - 15x - 8 = 0
2x² - 16x + x - 8 = 0
2x(x - 8) + 1(x - 8) = 0
(2x + 1)(x - 8) = 0
The factors are (2x +1) and (x - 8)
Determining the x-intercepts
(2x + 1)(x - 8) = 0
2x + 1 = 0 and x - 8 = 0
2x = -1 and x = 8
x = -1/2 and x = 8
Hence, the x-intercepts are -1/2 and 8

Belt B requires 3 hours on machine (M1), 2 hours on machine (M2) and 2 hour on machine (M3) and Belt C requires 5 hours on machine (M2) and 4 hours on machine (M3). There are 8 hours of time per day available on machine M1, 10 hours of time per day available on machine M2 and 15 hours of time per day available on machine M3. The profit gained from belt A is birr 3.00 per unit, from Belt B is birr 5.00 per unit, from belt C is birr 4.00 per unit. What should be the daily production of each type of belt so that the profit is maximum?
a) Formulate the problem as LPM
b) Solve the LPM using simplex algorithm.
c) Interpret the shadow prices
The number of belts produced must be positive: X1, X2, X3 >= 0
The shadow price of a constraint can be understand as the change in the objective function value for a unit change in the right-hand side (RHS) value of the constraint, with all other variables held constant.
What are constraints?A constraint is a condition of an optimization problem that should be satisfied the condition.
Here we can formulate this problem as a linear programming model (LPM):
Consider X1 be the number of belt A produced per day
Let X2 be the number of belt B produced per day
Let X3 be the number of belt C produced per day
The objective function is to maximize the profit, that is;
3X1 + 5X2 + 4X3.
The constraints are as follows:
The time spent on machine M1 must be less than or equal to 8 hours per day then;
2X1 + 3X2 <= 8
The time spent on machine M2 must be less than or equal to 10 hours per day then;
3X1 + 2X2 + 5X3 <= 10
The time spent on machine M3 must be less than or equal to 15 hours per day then we have
2X1 + 2X2 + 4X3 <= 15
Thus number of belts produced must be positive:
X1, X2, X3 >= 0
To solve this LPM using the simplex algorithm, you can follow these steps:
w In standard form, the objective function is to minimize the cost, and all constraints are in the form of "less than or equal to" a certain value.
The pivot row is the row that corresponds to the smallest positive ratio between the right-hand side (RHS) value and the corresponding pivot column element the constraint 2X1 + 3X2 ≤ 8.
Now Interpret the shadow prices.
The shadow price of a constraint can be understand as the change in the objective function value for a unit change in the right-hand side (RHS) value of the constraint, with all other variables held constant.
It can help to understand the value of the constraints in the LPM and how they contribute to the optimal solution.

□ ÷ 1,000 = 0.0327
□ ÷ 102 = 0.327
□ ÷ 1 = 3.27
□ ÷ 10 = 0.327

÷ 100 = 3.27
Note that the equations ÷ 102 and ÷ 1 are not true when 3.27 is used. The equation ÷ 102 is not true because 102 is not a multiple of 1,000, so dividing 3.27 by 102 will not result in a value that is close to 0. The equation ÷ 1 is not true because it is simply stating that 3.27 divided by 1 is equal to 3.27, which is true but not very interesting or useful.

create formulas out of the situations making the variable p=popcorn and s=soda
so,
3p + 6s = 54
and
4p + 9s = 77
then choose one variable to solve for
3p = 54 - 6s
divide both sides by 3
p = 18 - 2s
then plug your answer for p into the other equation:
4(18 - 2s) + 9s = 77
finally, solve for s
72 - 8s + 9s = 77
s = 5
if s=5 then
3p + 6(5) = 54
p = 8
