Discrete binomial distributions: assume that you are taking a true-false test that you have not studied for! the test only has 10 questions and each question has two possible answers (true or false). you plan to randomly guess on all 10 questions and the probability you get one correct is the same for all questions. what is the probability that you get less than 2 questions correct?

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

what i would say the best answer is a. 40.5

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
