Answer:
(c) y < -x +1
Step-by-step explanation:
You want the inequality that matches the graph.
Boundary lineThe boundary line of the shaded area has a negative slope: it falls one unit for each unit to the right, so the slope is ...
m = rise/run = -1/1 = -1
The line crosses the y-axis at y = 1, so the y-intercept is b = 1.
The equation of the boundary line is ...
y = mx + b
y = -x +1
ShadingThe boundary line is dashed, so its values are not part of the solution set. The shading is below the line, so only y-values less than those on the line are included.
The inequality is ...
y < -x +1 . . . . . choice C

which of the following values of alpha would cause exponential smoothing to respond the most slowly to forecast errors? question 38 options: 0.80 cannot be determined 0.20 0.40 0.10
Answers
Alpha value of 0.80 would cause exponential smoothing to respond the most slowly to forecast errors.
What is exponential smoothing?
Exponential smoothing is a method for estimating time series data in statistics. This method of forecasting is widely used in the estimation of the business cycle and other data with a linear trend. Exponential smoothing predicts the next time period by combining the most recent value of the series with a fraction of the prior forecast. The quantity of smoothing is determined by the alpha parameter.
Exponential smoothing can be described as follows:
\($$S_t=\alpha y_t + (1-\alpha)S_{t-1}$$\)
Where
S_t is the predicted value for time t,
α is the smoothing constanty is the actual value for time t−1
(1−α)S_{t−1} is the forecasted value for time t−1
Based on the equation, it is evident that the larger the value of α, the greater the contribution of the current period to the forecast. In the same way, the lower the value of α, the less significant the role of the current period in the forecast. As a result, it can be concluded that the smaller the value of α, the more slowly exponential smoothing reacts to forecast errors.
Therefore, the answer to this question is alpha value of 0.80 would cause exponential smoothing to respond the most slowly to forecast errors.

the wage for 35 people in a factory for one day i 7175. if on another day the factory paid 9225, how many people worked on that day, if the wage per day i the ame for everyone?
Answers
The total wage can only be an integer multiple of the wage per person.
The number of people working in the factory on a particular day can be calculated by dividing the total wage by the wage per person. This can be expressed mathematically as:
Number of People = Total Wage ÷ Wage per Person
For the given scenario, the number of people working on the day when the factory paid 9225 can be calculated as:
Number of People = 9225 ÷ 7175
Number of People = 1.287
Since the number of people has to be a whole number, this means that there were 1 people working in the factory on the day when the factory paid 9225. This is because when the wage per person is the same for everyone, the total wage can only be an integer multiple of the wage per person.

8. A juice container shaped like a cylinder has a base area of 100 cm2 and can hold 1500 cm3 of juice. The height of the juice container is
Answers
15 cm
Explanation:
The cylinder’s volume can be found by multiplying base by height. The formula for this would be base*height=volume. The base and volume are given, so plug the values in and solve for height.
base*height=volume
100*height=1500
height=15 cm
The height of a juice cylinder container with base area of 100 cm² and volume of 1500 cm³ is 15 cm
Base area of a cylinderBase area = πr²
base area = 100 cm²
100 = π × r²
r² = 100 / π
r = √100 / π
Volume of a cylindervolume = πr²h
1500 = π (√100 / π)² × h
1500 = π(100 / π) × h
1500 = 100h
divide both sides by 100
h = 1500 / 100
h = 15 cm

Trinity had $525.38 in a savings account at the beginning of the summer she wants to have at least $200 in the account by the end of the summer she withdraws $25 each week for food, clothes and movie tickets writing in a quality that represents triniti's situation. How many weeks can Trinity withdraw money from her account solve the inequality
Answers
Answer:
Trinity can withdraw $25 from her bank account for 13 weeks.
Step-by-step explanation:
If she wants to have at least $200 by the end of summer you need to subtract that much from what she has now. Which would be $325.38. Now you have to divide that number into 25, which should give you the number of week that money would last. That number is 13.0152, you don't need all those extra numbers so just use 13. No to check you work multiply 25 and 13. You get 325.
a) Using a 2-year moving average, the forecast for year 6= miles (round your response to the nearest whole number). b) If a 2-year moving average is used to make the forecast, the MAD based on this = miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.) c) The forecast for year 6 using a weighted 2-year moving average with weights of 0.40 and 0.60 (the weight of 0.60 is for the most recent period) =3,740 miles (round your response to the nearest whole number). The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.40 and 0.60= miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.) d) Using exponential smoothing with α=0.20 and the forecast for year 1 being 3,100 , the forecast for year 6=3,468 miles (round your response to the nearest whole number).
Answers
a) The forecast is approximately miles. b) the Mean Absolute Deviation (MAD) based on the forecast is approximately miles. c) The forecast for year 6 is approximately miles. d) the last forecast is 3,468 miles.
a) To calculate the forecast for year 6 using a 2-year moving average, we take the average of the mileage for years 5 and 4. This provides us with the forecasted value for year 6.
b) The Mean Absolute Deviation (MAD) for the 2-year moving average forecast is calculated by taking the absolute difference between the actual mileage for year 6 and the forecasted value and then finding the average of these differences.
c) When using a weighted 2-year moving average, we assign weights to the most recent and previous periods. The forecast for year 6 is calculated by multiplying the mileage for year 5 by 0.40 and the mileage for year 4 by 0.60, and summing these weighted values.
The MAD for the weighted 2-year moving average forecast is calculated in the same way as in part b, by taking the absolute difference between the actual mileage for year 6 and the weighted forecasted value and finding the average of these differences.
d) Exponential smoothing involves assigning a weight (α) to the most recent forecasted value and adjusting it with the previous actual value. The forecast for year 6 is calculated by adding α times the difference between the actual mileage for year 5 and the previous forecasted value, to the previous forecasted value.
In this case, with α=0.20 and a forecast of 3,100 miles for year 1, we perform this exponential smoothing calculation iteratively for each year until we reach year 6, resulting in the forecasted value of approximately 3,468 miles.

observations are drawn from a bell-shaped distribution with a mean of 20 and a standard deviation of 2. approximately what percentage of the observations fall between 16 and 24?
Answers
To find the percentage of observations that fall between 16 and 24, we can use the standard normal distribution table to convert these values to standard units and then find the corresponding cumulative probability.
First, we convert the values to standard units by subtracting the mean of 20 and dividing by the standard deviation of 2:
$16 \rightarrow (16-20)/2 = -2$
$24 \rightarrow (24-20)/2 = 2$
Next, we look up the cumulative probability for $-2$ and $2$ in a standard normal distribution table, which gives us 0.0228 and 0.9772, respectively.
The percentage of observations between 16 and 24 is equal to the difference between these two probabilities, which is $0.9772 - 0.0228 = 0.9544$, or 95.44%. So, approximately 95.44% of the observations fall between 16 and 24.

Answers
Answer:
Annual expenses INCLUDING cost of annual rent: = $17,597
Annual expenses EXCLUDING cost of annual rent: = $4,277
Step-by-step explanation:
Annual expenses EXCLUDING cost of annual rent:
Electricity = $980
Gas = $1,100 Phone/cable/Internet = $2,100
Insurance = $45
Lost interest = $52
Total = $980 + $1,100 + $2,100 + $45 + $52
= $4,277
Annual expenses EXCLUDING cost of annual rent: = $4,277
Annual expenses INCLUDING cost of annual rent:
Rent = $1,110 per month
Annual rent = $1,110 per month × 12
= $13,320
Electricity = $980
Gas = $1,100 Phone/cable/Internet = $2,100
Insurance = $45
Lost interest = $52
Total = $13,320 + $980 + $1,100 + $2,100 + $45 + $52
= $17,597
Annual expenses INCLUDING cost of annual rent: = $17,597
