The employees that the company had a year ago is 500.
How many employees were there last year?Percentage is the rate expressed as a number out of 100. Percentage is used to measure the frequency of a dataset. The sign that represents percentages is %.
The employees last year would be greater than the employees this year. The equation that can be used to represent employees last year is:
Employees this year = employees last year x (1 - percentage decrease)
335 = employees last year x (1 - 0.33)
335 = employees last year x 0.67
employees last year = 335 / 0.67
employees last year = 500

Use the expression for the slope from part B to write a general equation for the slope of any two points (a, b) and (c, d).
Using a slope value of 3, the general equation in point-slope form is: y - b = 3(x - a).
Recall:
Given the slope (m) of a line, we can write an equation in point-slope form of the line can be written if we know one of the points as, \(y - y_1 = m(x - x_1)\), where \((x_1, y_1)\) is a point on the line and m = slope.From the question given, the slope gotten from part B is missing in this question. However, let's assume the slope (m) = 3.
Using one of the points, say (a, b), to write a general equation in point slope form, substitute \((x_1, y_1)\) = (a, b) and m = 3 into \(y - y_1 = m(x - x_1)\).
Thus:
\(\mathbf{y - b = 3(x - a)}\)

What is the slope of the line shown?
Answer: slope = \(\frac{1}{2}\)
Step-by-step explanation:
Since we are given a graph with clear points, we will use "rise over run" by counting the units between points upwards and rightwards.
Since this line is going up from bottom left to upper right, we have a positive slope.
Starting at (0, -3) we count up one unit and right two units to (2, -2), giving us a slope of \(\frac{1}{2}\).

In the figure find the value of c in the interval [0, 4] on the x-axis that maximizes angle θ. c = ?
Answer:
Step-by-step explanation:
ERERRER3R3ERWEWREWRERE
The angle θ is maximized when c = 2 (halfway between two points).
What is maximized angle?The maximum angle at which a conveyor can be inclined while still delivering a predetermined amount of bulk material in a given amount of time. As the maximum angle is approached, the rate of bulk material handling is usually reduced.
Given that, in the figure, find the value of c in the interval [0, 4] on the x-axis that maximizes angle θ.
Express θ as a function of c, Let α be the angle to the left of θ and let β be the angle to the right, then,
tanα = 2/c
and tanβ = 2/(4-c)
At this point, we suppose that it might be easier to use cotangent in order to keep c inn numerator,
cotα = c/2
cotβ = (4-c)/2
We have, α+β+θ = π, so,
θ = π-α-β
= π-cot⁻¹c/2-cot⁻¹(4-c)/2
Differentiate, set equal to 0 and solve
dθ/dc = 1/1+(c/2)².1/2+1/1+(4-c/2)²(1/2)
Put dθ/dc = 0
1/1+(c/2)².1/2+1/1+(4-c/2)²(1/2) = 0
1/1+(c/2)²-1/1+(4-c/2)² = 0
1/1+(c/2)² = 1/1+(4-c/2)²
(4-c/2)² = (c/2)²
(c/2) = (4-c/2)
4-c = c
2c = 4
c = 2
Hence, The angle θ is maximized when c = 2 (halfway between two points).

Sonya is baking cookies. The table below shows the relationship between the number of batches of cookies she bakes and the number of cups of sugar she uses Number of Batches 1 2 3 Number of Cups of Sugar 2-7 47/17 6²2/2 Based on the relationship shown in the table, how many more cups of sugar does Sonya use to bake 9 batches of cookies than to bake 3 batches of cookies?
a6
b12
c13 1/2
d19 1/4
To find the difference in the number of cups of sugar used to bake 9 batches of cookies compared to 3 batches of cookies, we need to calculate the amount of sugar used for each case.
From the table, we can see that:
- For 1 batch of cookies, Sonya uses 2-7 cups of sugar.
- For 2 batches of cookies, Sonya uses 47/17 cups of sugar.
- For 3 batches of cookies, Sonya uses 6²2/2 cups of sugar.
To calculate the amount of sugar used for 9 batches of cookies, we can use the pattern observed in the given values:
- For 4 batches of cookies, Sonya uses 2-7 cups of sugar.
- For 5 batches of cookies, Sonya uses 47/17 cups of sugar.
- For 6 batches of cookies, Sonya uses 6²2/2 cups of sugar.
- For 7 batches of cookies, Sonya uses 2-7 cups of sugar.
- For 8 batches of cookies, Sonya uses 47/17 cups of sugar.
- For 9 batches of cookies, Sonya uses 6²2/2 cups of sugar.
Therefore, to find the difference in the number of cups of sugar used to bake 9 batches of cookies compared to 3 batches of cookies, we subtract the amounts:
Amount of sugar for 9 batches - Amount of sugar for 3 batches
[(2-7) + (47/17) + (6²2/2)] - [(2-7) + (47/17) + (6²2/2)]
Simplifying the expression, we get:
[(2-7) + (47/17) + (6²2/2)] - [(2-7) + (47/17) + (6²2/2)]
= 6²2/2 - 6²2/2
= 0
Therefore, the correct answer is:
d) 19 1/4
There is no difference in the number of cups of sugar used to bake 9 batches of cookies compared to 3 batches of cookies.

Putting forecast errors into perspective is best done using : a.linear decision rules. b. hindsight. c. exponential smoothing. d. MAPE. e.MAD.
Putting forecast errors into perspective is best done using MAPE and MAD. These are two common measures of forecast accuracy that can help evaluate the performance of a forecasting model and put forecast errors into perspective.
MAPE (Mean Absolute Percentage Error) measures the average absolute percentage difference between actual and forecasted values. This metric is useful because it expresses forecast accuracy in relative terms, allowing us to compare forecast errors across different data sets and time periods. However, it can be sensitive to extreme values and can be misleading when dealing with small or negative actual values. MAD (Mean Absolute Deviation) measures the average absolute difference between actual and forecasted values, without regard for direction. This metric is more robust to extreme values and is easier to interpret than MAPE, making it a popular choice for evaluating forecast accuracy. Using MAPE and MAD, we can identify areas where the forecasting model is performing well and where it needs improvement. By putting forecast errors into perspective, we can make informed decisions about how to adjust our forecasting approach to improve accuracy and reliability.

How can you tell if a point is a solution to a two variable inequality?
One way to determine whether a point is a solution to a two-variable inequality is to substitute the values of the variables in the inequality and determine whether the inequality is true or false. If the inequality is true, the point is a solution, and if the inequality is false, the point is not a solution.
For example, consider the inequality 2x + 3y > 7. Let’s see if the point (1,2) is a solution. To do so, substitute x=1 and y=2 into the inequality:2(1) + 3(2) > 7 Simplify to get:2 + 6 > 7 This is true, so the point (1,2) is a solution to the inequality. Conversely, let’s see if the point (4,-1) is a solution. To do so, substitute x=4 and y=-1 into the inequality:2(4) + 3(-1) > 7 Simplify to get:8 - 3 > 7 This is false, so the point (4,-1) is not a solution to the inequality .There are some general rules that can be followed to help determine which side of a line is shaded in an inequality. If the inequality is greater than or less than, the line should be dashed, and the shading should be above or below the line, respectively. If the inequality is greater than or equal to or less than or equal to, the line should be solid, and the shading should be above or below the line, respectively.

Each minute after costs $0.12 so just divide the 2 numbers. You should get 23.75, that's the number of minutes. Add the 3 minutes back on to get the total time and you get 26.75, it says round to the nearest whole number, which would be 27, but since that would cost more money than Jane actually has, I think it would be 26 minutes
