how many positive integers with three digits have at least one digit divisible by 3?
There are a total of 900 three-digit positive integers, from 100 to 999.
To count the number of three-digit positive integers with at least one digit divisible by 3, we can use the principle of inclusion-exclusion.
First, we count the number of three-digit positive integers that have at least one digit divisible by 3. There are three possibilities for the position of the digit that is divisible by 3: it can be in the hundreds place, the tens place, or the units place.
For the hundreds place, there are 3 choices (3, 6, or 9) for the digit that is divisible by 3, and 10 choices for each of the other two digits. So there are 3 x 10 x 10 = 300 three-digit positive integers that have a digit divisible by 3 in the hundreds place.
Similarly, there are 3 x 10 x 10 = 300 three-digit positive integers that have a digit divisible by 3 in the tens place, and 3 x 10 x 10 = 300 three-digit positive integers that have a digit divisible by 3 in the units place.
However, we have overcounted the number of three-digit positive integers that have two or three digits divisible by 3. To correct for this, we need to subtract the number of three-digit positive integers that have two digits divisible by 3, and then add back in the number of three-digit positive integers that have all three digits divisible by 3.
There are two possibilities for the positions of the two digits that are divisible by 3: they can be in the hundreds and tens places, or in the tens and units places. For each of these cases, there are 3 x 3 = 9 choices for the two digits that are divisible by 3, and 10 choices for the remaining digit. So there are 2 x 9 x 10 = 180 three-digit positive integers that have two digits divisible by 3.
There is only one three-digit positive integer, 999, that has all three digits divisible by 3.
Therefore, the number of three-digit positive integers with at least one digit divisible by 3 is:
300 + 300 + 300 - 180 + 1 = 721
So there are 721 three-digit positive integers with at least one digit divisible by 3.

When a patient has unequal pupils why is it most important ask if they have a history of eye surgery - EMT
When a patient has unequal pupils (anisocoria), it is important for an EMT to ask if they have a history of eye surgery because this may indicate a potential underlying cause of the anisocoria.
There are several conditions that can cause anisocoria, including nerve damage, medications, or underlying medical conditions such as brain tumors, aneurysms, or infections. However, if a patient has a history of eye surgery, this may suggest that the anisocoria is related to the surgery itself or to a complication of the surgery.
For example, anisocoria can be a complication of cataract surgery or corneal transplant surgery. It can also be a sign of other complications, such as retinal detachment or glaucoma, which may occur after eye surgery.
Therefore, if a patient has a history of eye surgery and presents with anisocoria, this information can help the EMT to determine the possible causes of the anisocoria and to provide appropriate care or transport to a medical facility that can manage the patient's condition.
Sumner has a moderate view on abortion: he thinks that some abortions are permissible and some are not. What trait is relevant in determining whether an abortion is permissible, according to Sumner? Why is this trait important?
According to Sumner, the trait that is relevant in determining whether an abortion is permissible is the moral status of the fetus.
What is the view?Sumner contends that the moral position of the fetus is correlated with its stage of cognitive development and capacity for consciousness. He holds that a kid who is still developing its capacity for consciousness and self-awareness is capable of being aborted and does not yet have a fully developed moral viewpoint.
In contrast, a fetus with the ability to think for itself and have moral agency should not be aborted unless the mother's life or health is in jeopardy.

Pesticide use in agriculture has unintended environmental impacts. Although pesticides were designed to protect crops from pests, they have negative consequences such as soil contamination, water pollution, and harmful effects on non-target organisms. These impacts undermine the sustainability of agricultural systems, posing a threat to human health and ecosystems. To address these challenges, there is a need for alternative pest management practices that prioritize ecological and health-friendly approaches, reduce the use of harmful chemicals and protect biodiversity. Effective policies and incentives can promote sustainable agriculture that balances productivity and environmental protection.

Suppose someone argued that the reason twins often share multiple sclerosis is not because it's hereditary, but because of some abnormality in the mother's pregnancy, such as maternal exposure to a toxin or virus. What argument could you give against this hypothesis?
An argument against this hypothesis could be it is likely that both genetic and environmental factors contribute to the development of MS.
What is the argument against this hypothesis?While it is possible that maternal exposure to toxins or viruses during pregnancy can increase the risk of multiple sclerosis in twins, this explanation does not fully account for the observed patterns of inheritance of the disease in families with a history of MS.
Twin studies have shown that identical twins, who share 100% of their genes, are much more likely to both develop MS compared to fraternal twins, who share only 50% of their genes on average.
