The average age of a breed of dog is 19. 5 years. If the distribution of their ages is normal and 20% of dogs are older than 22. 6 years, find the standard deviation
The standard deviation of the ages of this breed of dog is approximately 4.4 years.
To find the standard deviation, we can use the concept of z-scores and the cumulative distribution function (CDF) of a standard normal distribution. Let's denote the average age as μ (mu) and the standard deviation as σ (sigma).
Given that the average age of the breed is 19.5 years, we can set μ = 19.5. We are also given that 20% of the dogs are older than 22.6 years. Using the z-score formula, we can calculate the z-score corresponding to this percentile:
z = (x - μ) / σ
Where x is the given value (22.6 years) and z is the z-score. Rearranging the formula, we can solve for σ:
σ = (x - μ) / z
Plugging in the values, we have:
σ = (22.6 - 19.5) / z
To find the z-score corresponding to the 20th percentile, we can use the inverse CDF of the standard normal distribution. Using statistical software or a z-table, we find that the z-score corresponding to the 20th percentile is approximately -0.84.
Substituting the values, we get:
σ = (22.6 - 19.5) / -0.84 ≈ 3.7 / -0.84 ≈ -4.4

The Academic Quiz advisor needs to choose the top member to compete in a final challenge.
When she calculated the team members' scores on qualifying tests over the past year,
she found that Tobin and Yolanda had approximately the same mean score.
The MAD for Tobin's scores is 28.3, and the IQR is 39.8.
The MAD for Yolanda's scores is 9.7, and the IQR is 18.5. Which statement is true?
"The MAD for Yolanda's scores is 9.7, and the IQR is 18.5" is true.
Yolanda would be a better choice to compete in the final challenge, as her consistent performance is more likely to result in a good outcome. However, it's important to note that other factors, such as knowledge and skill, should also be considered when selecting the top member to compete.
Based on the given information, we can conclude that Yolanda is the better candidate for the final challenge. The mean score of Tobin and Yolanda is approximately the same, which means that their average performance is similar. However, the MAD and IQR of Yolanda's scores are significantly lower than Tobin's scores.
The MAD (Mean Absolute Deviation) measures the average distance between each data point and the mean of the dataset. Therefore, the lower the MAD, the less deviation there is in the dataset, indicating that Yolanda's scores are more consistent and reliable compared to Tobin's.
Similarly, the IQR (Interquartile Range) measures the spread of the middle 50% of the dataset. A lower IQR suggests that the data is more tightly clustered around the median, which is another indication that Yolanda's scores are more consistent.
Therefore, Yolanda would be a better choice to compete in the final challenge, as her consistent performance is more likely to result in a good outcome. However, it's important to note that other factors, such as knowledge and skill, should also be considered when selecting the top member to compete.

When proving the Pythagorean Theorem, we use the given diagram. What is the area of all four triangles combined?
Answer:OPTION B) 2ab
Explanation:Side of larger square = (a + b) units
Side of smaller square = c units
To Find:
The area of all four triangles combined = ?
Solution:
a^2 + b^2 = c^2 (Pythagoras theorem) -(1)
The area of all four triangles combined = Area of larger square - Area of smaller square
The area of all four triangles combined = (a + b)^2 - c^2
The area of all four triangles combined = a^2 + b^2 + 2ab - (a^2 + b^2) {By (1)}
The area of all four triangles combined = a^2 + b^2 + 2ab - a^2 - b^2
The area of all four triangles combined = a^2 - a^2 + b^2 - b^2 + 2ab
Therefore, The area of all four triangles combined = 2ab sq. units

Quentin is preparing a report for his earth science class. He creates a table showing what a person can do to keep safe from natural hazards. He reviews his table and realizes that it is not correct.
Which hazards should Quentin switch to correct his report?
drought and hurricane
hurricane and rip current
rip current and wildfire
wildfire and drought
Answer:
Explanation:
Quentin should switch drought and wildfire to correct his report. Drought and wildfire are both natural hazards, but they are not related to each other. Drought is a prolonged period of dry weather that can lead to crop failure, water shortages, and other problems, while wildfire is a large, destructive fire that is typically caused by lightning or human activity. In contrast, hurricane and rip current are both related to water. A hurricane is a tropical cyclone with strong winds and heavy rainfall, while a rip current is a strong, narrow current of water that can pull swimmers out to sea. Switching these hazards in the table will help ensure that the information is correct and accurate.
