Courtney makes 80 % 80%80, percent of the free throws she attempts. She often stays after practice to shoot sets of 10 1010 free throws. Assume that the results of free throws are independent from each other. What are the mean and standard deviation of the number of free throws she makes in each set of 10 1010?

Mean: 8 free throws

Standard Deviation: 1.3 free throws

Step-by-step explanation:

This is a binomial random variable, so we can use the formula , where n is the number of trials, and p is the probability. Since we know both of these values, just plug it in for the mean.

For the standard deviation, we use the formula σ = . Since we know what np is, we can replace those 2, giving us . Again, p is our probability, so this gives us our final equation of , which simplifies to . Using a calculator, we get 1.264, which is 1.3 rounded to the nearest tenth.

Hope this helped :)

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
