1. Sunlight is not considered an environmental hazard.
Sunlight is not considered an environmental hazard because it is a natural source of light that is essential to life on Earth. Sunlight provides energy for photosynthesis, which is the process by which plants produce oxygen and food. It is also a source of vitamin D, which is important for bone health in humans and animals. However, excessive exposure to sunlight can be harmful to living organisms.
This is because the sun emits ultraviolet (UV) radiation, which can cause skin damage, premature aging, and skin cancer in humans. UV radiation can also be harmful to animals and plants, causing DNA damage, reduced growth and reproduction, and even death.
In addition, sunlight can indirectly contribute to environmental hazards. For example, when sunlight interacts with pollutants in the atmosphere, it can lead to the formation of smog and ground-level ozone, which can cause respiratory problems in humans and animals.
Sunlight can also contribute to climate change by warming the Earth's surface, which can have negative impacts on ecosystems and human societies.In conclusion, while sunlight is not inherently an environmental hazard, it can have negative impacts on living organisms and contribute to other environmental hazards if not properly managed.
Therefore, it is important to protect ourselves from excessive exposure to UV radiation and to reduce our greenhouse gas emissions to mitigate the effects of climate change.

Building sheep pens : darsh and darpan are fencing off a large rectangular area to build some temporary holding pens. to prep the males, females, and kids, they are separated into three smaller and equal-size pens partitioned
The larger rectangle will be a square with sides of 96 ft while the pens will have 96 ft of length and 31 ft of width
How to Maximize Area of rectangle?
The side lengths of the big rectangle are x and y and so we have the following expression for its area A:
A = x*y
This is tied to the constraint that the perimeter should not be larger than the available fencing , Thus;
2x + 2y = 384 (All the fencing is used to maximize the area)
y = (384 - 2x)/2
y = 192 - x
Put 192 - x for y in A to get;
A = x(192 - x)
A = 192x - x²
Completing the square gives;
A = 9216 - (x - 96)²
Thus;
A is maximum at;
x - 96 = 0
x = 96 ft
y = 192 - 96
y = 96 ft
Then since we maximised the area of the bigger rectangle , we have maximised the area of the smaller pens. The dimensions will be;
x_small = 96 ft /3
x_small = 31 ft
y_small = 96 ft
Complete question is;

King Midas wanted to be the richest king in the world, and one day, he had the chance to make it happen. His servants had captured a satyr, a half-man and half-goat creature. The satyr happened to be good friends with a very powerful god named Dionysus. (2) Midas thought that Dionysus just might give him a reward for finding the satyr, so he asked the satyr to stay at the palace where he would be treated as a guest. The satyr was given a nice room with fine linens and any food he desired. The satyr was quite happy about all this. (3) Soon, Dionysus arrived at the palace, as he had been searching for the satyr. Midas took Dionysus to see the satyr, who told the god about all the rich foods and fine things the king had given him. Dionysus was grateful to Midas for treating his friend so well, and he offered to grant Midas one wish. (4) "I wish that everything I touch would turn to gold!" Midas exclaimed without thinking. He couldn't believe his luck! Now he would definitely become the world's richest king. Dionysus asked if he was sure, and because Midas said he was sure, Dionysus granted the wish. (5) For the next few hours, Midas was in heaven. He touched flowers, and they became gold. He touched his bed, and it became gold. He touched his castle, and it became gold. Then, because he was thirsty, Midas tried to drink some water, but it dried as it touched his lips and also became gold. He tried to eat an orange, but it too turned into the precious metal. Finally, his daughter ran to give him a hug, and she too became gold! Midas realized that his wish had become a curse. (6) Midas begged Dionysus to take back his wish. Dionysus saw how sorry Midas was and took pity on him. He sent Midas to bathe in the River Pactolus. The waters cleansed him and released him from the golden touch. Midas realized then that riches are not the most important things in the world. 4 The sixth paragraph is mostly about A. Midas begging Dionysus to help him. B. Dionysus seeing how sorry Midas is. C. Dionysus releasing Midas from his wish. D. Midas traveling to the river Pactolus.

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
