Suppose tori has an unfair coin which lands on tails with probability 0.28 when flipped. if she flips the coin 10 times, find each of the following: question 2 options: the standard deviation of the number of tails p(no more than 3 tails) the mean number of tails p(exactly 4 tails) p(at least 5 tails) p(more than 3 tails) p(no tails) p(exactly 1 tail) p(at least 1 tail) p(less than or equal to 2 tails) 1. 0.1798 2. 0.7021 3. 2.8 4. 0.1181 5. 0.1456 6. 0.0374 7. 0.9626 8. 0.2979 9. 0.4378 10. 1.42

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
