Suppose that 3% of the 2 million high school students who take the SAT each year receive special accommodations because of docum

ented disabilities. Consider a random sample of 20 students who have recently taken the test. (Round your probabilities to three decimal places.)(a) What is the probability that exactly 1 received a special accommodation?(b) What is the probability that at least 1 received a special accommodation?(c) What is the probability that at least 2 received a special accommodation?(d) What is the probability that the number among the 20 who received a special accommodation is within 2 standard deviations of the number you would expect to be accommodated? Hint: First, calculate ? and ?. Then calculate the probabilities for all integers between ? - 2? and ? + 2?.

Please help me thanks
makvit [3.9K]

Answer:

324 inches^2

Step-by-step explanation:

So to start off we will find the area of the rectangles.

So on has side lenghts of 15 and 6 meters.

So the area for that would be 90, after multiplying 15 and 6.

The next one has side lenghts of 9 and 6.

And after multiplying you would get 54.

For the last rectangle the side lenghts are 12 and 6.

And after multiplying you would get 72.

So adding all that together is 216 meters^2.

Now for the two triangles.

The height is 9 and the base is 12.

So after multiplying you would get 54.

Same for the other one so adding them up it would be 108.

Hence, adding 108 and 216 the answer is 324inches^2
