The population standard deviation is approximately 16.78 when rounded to two decimal places.
To determine the population standard deviation (σ), we can use the formula relating the standard error of the mean (SE) and the sample size (n) to the population standard deviation:
σ = SE × √(n)
Given that the standard error of the mean (SE) is 1.35 and the sample size (n) is 155, we can substitute these values into the formula:
σ = 1.35 × √(155)
Calculating the square root of 155, we find:
σ = 1.35 × 12.4499
Multiplying 1.35 by 12.4499, we get:
σ ≈ 16.7823
It's important to note that the standard error of the mean (SE) is calculated as the standard deviation of the sample divided by the square root of the sample size:
SE = s / √(n)
The standard error of the mean (SE) is given as 1.35, so we directly used it in the formula to determine the population standard deviation.

One map shows rates in 2007 and the second shows unemployment rates in 2009. A map key shows that gray represents 16.5 percent or greater unemployment, purple represents 13.1-16.4 percent unemployment, dark red represents 11.0 - 13.0 percent unemployment, bright red represents 8.9-10.9 percent unemployment, dark orange represents 7.1-8.8 percent unemployment, light orange represents 5.5-7.0 percent unemployment, bright yellow represents 4.1-5.4 percent unemployment, white represents 4.0 percent or lower unemployment. The 2007 map shows a large portion of the Midwest in white. The west coast is largely yellow and orange. The east coast and central part of the U.S. are also largely yellow and orange. There are a few scattered splotches of red, and a very few purple and gray areas. The 2009 map is dramatically different.

2. In its first year, “DM Trading” had the following experience: Unit selling price birr 100 Sales 50,000 units Total fixed cost birr 400,000 TVC birr 3,000,000 Required: a) Develop TR, TC and profit functions for the company in terms of quantity b) Find the breakeven point in terms of quantity and sales volume.
Answers
a) The total revenue (TR) function can be calculated by multiplying the unit selling price by the quantity sold.
In this case, TR = 100 * Q, where Q represents the quantity sold. The total cost (TC) function consists of the sum of fixed costs (FC) and total variable costs (TVC). Given that the fixed costs are 400,000 birr and the TVC is 3,000,000 birr, the TC function can be expressed as:TC = FC + TVC = 400,000 + 3,000,000 = 3,400,000 birr.
The profit function (P) can be determined by subtracting the total cost from the total revenue, so P = TR - TC = 100Q - 3,400,000 birr.
b) The breakeven point can be found by setting the profit function equal to zero, as this is the point where total revenue equals total cost.
In this case, 100Q - 3,400,000 = 0. Solving for Q, we find Q = 3,400,000 / 100 = 34,000 units. Therefore, the breakeven point in terms of quantity is 34,000 units. To calculate the sales volume at the breakeven point, we can multiply the breakeven quantity by the unit selling price:Sales Volume = 34,000 units * 100 birr/unit = 3,400,000 birr. Hence, the breakeven point in terms of sales volume is 3,400,000 birr.

The stock solution is prepared by dissolving 1.0 +/- 0.01 g of substance in a 1000 +/- 0.4 ml volumetric flask. The standard solutions are prepared by adding x +/- 0.1 ml stock solution (x is the volume you need) to a 100 +/- 0.1 ml volumetric flask, then top up with water to the mark.
a) Calculate the relative uncertainty in concentration for the three standard solutions. Hint calculate ey/y.
b) Calculate the absolute uncertainty in concentration for the three standard solutions. Hint calculate ey.
Answers
For the 0.1 g/L solution:
- Nominal value of concentration (y) = 0.1 g/L
- Absolute uncertainty (ey) = (0.01 g / 1.0 g) * 1000 mL = 0.1 mL
- Relative uncertainty (ey/y) = (0.1 mL / 100 mL) * 100% = 0.1%
For the 0.05 g/L solution:
- Nominal value of concentration (y) = 0.05 g/L
- Absolute uncertainty (ey) = (0.01 g / 1.0 g) * x mL + (0.4 mL / 1000 mL) * 100 mL = 0.01x + 0.004 mL
- Relative uncertainty (ey/y) = (0.01x + 0.004 mL) / (0.05 g/L * 100 mL) * 100%
For the 0.01 g/L solution:
- Nominal value of concentration (y) = 0.01 g/L
- Absolute uncertainty (ey) = (0.01 g / 1.0 g) * x mL + (0.4 mL / 1000 mL) * 100 mL = 0.01x + 0.004 mL
- Relative uncertainty (ey/y) = (0.01x + 0.004 mL) / (0.01 g/L * 100 mL) * 100%
b) The absolute uncertainty in concentration for the three standard solutions can be calculated using the formula ey, where ey is the absolute uncertainty.
For the 0.1 g/L solution:
- Absolute uncertainty (ey) = (0.01 g / 1.0 g) * 1000 mL = 0.1 mL
For the 0.05 g/L solution:
- Absolute uncertainty (ey) = (0.01 g / 1.0 g) * x mL + (0.4 mL / 1000 mL) * 100 mL = 0.01x + 0.4 mL

A die is tossed three times. What is probability that a 6 will show in the upward face at least once?
Answers
Answer:
1/216.
Explanation:
The probability of a 6 appearing on any single roll of a fair die is 1/6. Since the rolls are independent, the probability of a 6 appearing on all three rolls is (1/6) x (1/6) x (1/6) = 1/216. Therefore, the probability that a 6 will not appear in any of the three rolls is 1 - 1/216 = 215/216. Finally, the probability that a 6 will appear at least once in the three rolls is 1 - 215/216 = 1/216. Thus, the probability of a 6 appearing in the upward face at least once is 1/216.

10. A researcher is interested in estimating the mean alcohol content for a particular brand of cough medicine. They randomly sample 50 bottles of this brand and find a sample mean of 8.6 (percent alcohol). Let u denote the mean alcohol content (in percent) for the population of all bottles of the brand under study. The population standard deviation is 2.2. a.) Construct a 95% confidence interval for u
Answers
Answer:
To construct a 95% confidence interval for the mean alcohol content of the population of all bottles of the brand under study, you can use the following formula:
Sample mean +/- (t-value * standard error)
The t-value can be found using a t-distribution table or a computer program. It is based on the desired confidence level (in this case, 95%) and the degrees of freedom, which is the sample size minus 1 (in this case, 50-1=49).
The standard error is calculated as:
Standard error = population standard deviation / sqrt(sample size)
Plugging in the given values, you get:
Standard error = 2.2 / sqrt(50) = 0.22
Using a t-distribution table or computer program, you can find that the t-value for a 95% confidence interval with 49 degrees of freedom is 2.01.
Therefore, the 95% confidence interval for the mean alcohol content of the population of all bottles of the brand under study is:
8.6 +/- (2.01 * 0.22)
Which simplifies to:
8.6 +/- 0.44
So the 95% confidence interval for the mean alcohol content of the population is (8.16, 8.94).

look at these two triangles triangle b is a reflection of triangle a
Answers
Triangle B is a reflection of Triangle A.
Triangle B is a mirror image of Triangle A. The corresponding sides, angles, and vertices of the two triangles will be equal in measure, but they will face in opposite directions.
Reflection is a transformation in which a figure is flipped over a line to create a mirror image. In the case of triangles, a reflection would involve flipping the triangle over a line to create a new triangle that is a mirror image of the original.
When Triangle B is a reflection of Triangle A, it means that Triangle B is created by reflecting Triangle A over a line.
The line of reflection is an imaginary line that serves as the axis of symmetry for the reflection. It is a line that each point on Triangle A is reflected across to create the corresponding point on Triangle B.
When Triangle B is a reflection of Triangle A, the corresponding sides and angles of the triangles will be equal in measure. This is because reflection preserves the shape and size of the original figure.
The vertices of Triangle B will be the mirror image of the vertices of Triangle A. For example, if vertex A in Triangle A is reflected to vertex A' in Triangle B, the distance between the line of reflection and vertex A will be equal to the distance between the line of reflection and vertex A'.
Similarly, the angles in Triangle B will be equal in measure to the corresponding angles in Triangle A.
The sides of Triangle B will have the same lengths as the corresponding sides of Triangle A.
Overall, when Triangle B is a reflection of Triangle A, the two triangles will have the same shape and size but will be facing in opposite directions.
By understanding the concept of reflection and the properties of a reflection, we can conclude that Triangle B is a mirror image of Triangle A. The corresponding sides, angles, and vertices of the two triangles will be equal in measure, but they will face in opposite directions.

The probability that the mean of a month's reviews will take Yoonie from 3.5 to 4.25 hrs is 0.7499.
What is the probability?We first get the z score for the two values. As z = (x - u) sqrt(n) / s, then as
x1 = lower bound = 3.5
x2 = upper bound = 4.25
u = mean = 4
n = sample size = 16
s = standard deviation = 1.2
Thus, the two z scores are
z1 = lower z score = (x1 - u) * sqrt(n) / s = -1.666666667
z2 = upper z score = (x2 - u) * sqrt(n) / s = 0.833333333
Using table/technology, the left-tailed areas between these z scores is
P(z < z1) = 0.047790352
P(z < z2) = 0.797671619

Now you can see that \(\frac{1}{3} *x^{2} - 2\) must be equal to \(\frac{1}{3}*(x^{2} - k^{2})\) which is equal to \(\frac{1}{3}*x^{2} - \frac{1}{3}*k^{2}\). Now we just need to solve \(2 = \frac{1}{3}*k^{2}\). The final answer is \(k = +- \sqrt{6}\).
