If an outcome measure is normally distributed, this means that
A normally distributed result means that when the data is plotted on a graph, we can actually see a bell shaped curve. That highest frequency or peak is centered on the average value. Because it is shaped like this, we can say that:
most scores are around the average with some scores being lower or higher
In ∆ABC, the median AM (M ∈ BC ) is perpendicular to the angle bisector BK (K ∈ AC ). Find AB, if BC = 12 in.
Answer:
The answer is 6 inches
Step-by-step explanation:
Since the angle is isosceles, angle A and angle B have the same measure,
The sum of the angles of any triangle is 180°.
So 2 times the measure of angle B plus 120° = 180°, then the equation:
Solving for x we get:
Now we use the law of sine on the triangle BMC like this:
Solving for BC we get :
We apply the law of sin again on the isosceles triangle ABC like this:
Solving for AB we get:

Anyone know how to do the fireworks display portfolio?
Final answer:
To create a fireworks display portfolio, you can use physical methods such as printing photos or employ digital tools like a word processor, presentation software, or Web 2.0 tools. Ensure you use your own photos, review them to demonstrate key concepts learned, and include them in your final project.
Explanation:
To create a fireworks display portfolio, you have several options. One method involves printing your photos and physically attaching them to paper or poster board, then writing reflections beside them. For a more modern touch, you might opt to create your portfolio digitally using a word processor. In this format, it's important to only use your own photos rather than those with Creative Commons licenses or other sourced images.
Alternatively, you can employ presentation software or various Web 2.0 tools like Glogster (EDU) or VoiceThread for a dynamic and interactive portfolio. When creating your fireworks display portfolio, it is crucial to consider the visual and descriptive elements that highlight what you've learned. Make sure to review your flash photos, choose the sets that best demonstrate the three distance settings or the three settings in the assignment prompt, and be ready to discuss their relevance to the concepts learned in class, such as conservation of momentum and center of mass regarding fireworks.
Lastly, ensure that you download your photos to a computer to include them in the end-of-course final project portfolio. This portfolio will serve as a cohesive collection of your work and understanding of the subject matter.

Evaluate the summation of 2 n plus 5, from n equals 1 to 12..
A. 29
B. 36
C. 216
D. 432
Option: C is the correct answer.
C. 216
Step-by-step explanation:We are asked to evaluate the sum of the following summation:
[tex]\sum_{n=1}^{12} (2n+5)[/tex]
Now, this summation could also be written as:
[tex]\sum_{n=1}^{12} (2n+5)=\sum_{n=1}^{12} 2n+\sum_{n=1}^{12} 5[/tex]
i.e.
[tex]\sum_{n=1}^{12} (2n+5)=2\sum_{n=1}^{12} n+\sum_{n=1}^{12} 5[/tex]
Now, we know that:
[tex]\sum_{n=1}^{12} n=1+2+3+4+....+12\\\\i.e.\\\\\sum_{n=1}^{12} n=\dfrac{12(12+1)}{2}[/tex]
Since,
[tex]\sum_{i=1}^{n} i=\dfrac{n(n+1)}{2}[/tex]
i.e.
[tex]\sum_{n=1}^{12} n=78[/tex]
and
[tex]\sum_{n=1}^{12} 5=5+5+....+5\ (\text{twelve\ times})\\\\i.e.\\\\\sum_{n=1}^{12} 12=12\times 5\\\\i.e.\\\\\sum_{n=1}^{12} n=60[/tex]
Hence, we have:
[tex]\sum_{n=1}^{12} (2n+5)=2\times 78+60[/tex]
i.e.
[tex]\sum_{n=1}^{12} (2n+5)=156+60[/tex]
i.e.
[tex]\sum_{n=1}^{12} (2n+5)=216[/tex]

Economists recommend that the GDP (gross domestic product) growth rate of a nation be between 7.1 and 7.9 percent inclusively. Identify the compound inequality that show these GDP rates.
7.1 ≤ g ≤ 7.9
7.1 ≤ g <7.9
7.1 < g <7.9
7.1 < g ≤ 7.9
The compound inequality which represents the recommendation of economists for a GDP growth rate to be between 7.1 and 7.9 percent (inclusive) is given by '7.1 ≤ g ≤ 7.9'. This mathematical expression indicates that the acceptable rates are all the values including and between 7.1 & 7.9.
Explanation:In the context of mathematics, specifically the subject of inequalities, the student's question is asking to represent the given GDP rates as a compound inequality. A compound inequality is a statement with two inequalities joined by the word 'and' or 'or'.
Here, economists recommend the GDP growth rate to be between 7.1 and 7.9 percent (inclusive). So, the GDP growth rate (let's denote it as 'g') is more than or equal to 7.1 percent and, at the same time, less than or equal to 7.9 percent. So, the compound inequality which represents this situation is 7.1 ≤ g ≤ 7.9. So the correct option from the provided ones is the first one: '7.1 ≤ g ≤ 7.9'.
This inequality tells us that the growth rates 'g' are all the values including and between 7.1 & 7.9. This is crucial information for economists when monitoring the health and progress of a nation's economy. The percentage rate of GDP growth is a measure of economic success and can impact many aspects like standard of living, employment rates, and business growth.

Twelve pennies are arranged in a row on a table every other coin is replaced with a nickel then every third coin is replaced with a dime finally every fourth coin is replaced with a quarter what is the total value of the coins on the table?
Final answer:
The sequence of substitutions of the coins on the table results in a final arrangement of coins with a total value of 121 cents or $1.21. This problem combines sequence patterns with coin values to find the total.
Explanation:
We have a problem involving a series of substitutions of coins, and we need to calculate the total value of the coins on the table after these substitutions. We start with 12 pennies, which are initially worth 1 cent each.
Step 1: Every other coin is replaced with a nickel, so we replace every 2nd penny with a 5-cent coin (nickel). The sequence starts with a penny (P), so the even positions will now be nickels (N). The sequence now looks like P, N, P, N, P, N, P, N, P, N, P, N.
Step 2: Every third coin is replaced with a dime, which is worth 10 cents. This means the 3rd, 6th, 9th, and 12th positions will now be dimes (D). The sequence becomes P, N, D, N, P, D, P, N, D, N, P, D.
Step 3: Every fourth coin is replaced with a quarter, which is worth 25 cents. Positions 4, 8, and 12 are affected. The sequence is now P, N, D, Q, P, D, P, Q, D, N, P, Q.
Let’s calculate the total value of the coins:
6 Pennies (P): 6 * 1 cent = 6 cents
2 Nickels (N): 2 * 5 cents = 10 cents
3 Dimes (D): 3 * 10 cents = 30 cents
3 Quarters (Q): 3 * 25 cents = 75 cents
Adding all these values together: 6 cents + 10 cents + 30 cents + 75 cents = 121 cents or $1.21.
This problem requires understanding of sequence patterns and knowledge of United States coin values to determine the total value of the coins.
