Hi Dear,
I have given my 100% to solve your problem.
So, please help me out by just thumbs up.
Thank you, so much.

An archer is able to hit the bull's-eye 32% of the time. If she shoots 9 arrows, what is the probability that she does not get exactly 4 bull's-eyes? Assume each shot is independent of the others. Express your answer as a percentage rounded to the nearest hundredth.
an archer is able to hit the bulls-eye 50% of the time. if she shoots 8 arrows, what is the probability that she gets exactly 4 bulls-eyes? Assume each shot is independent of the others.
An Olympic archer is able to hit the bull's-eye 89% of the time. Assume each shot is independent of the others. She shoots 8 arrows. a) How many bull's-eyes do you expect her to get? b) What is the standard deviation? c) If she keeps shooting arrows until she hits the bull's-eye, how long do you expect it will take?
An Olympic archer is able to hit the bull's-eye 84% of the time. Assume each shot is independent of the others. She shoots 6 arrows. a) How many bull's-eyes do you expect her to get? b) What is the standard deviation? c) If she keeps shooting arrows until she hits the bull's-eye, how long do you expect it will take?
An Olympic archer misses the bull's eye 14% of the time. Assume each shot is independent of the others. If she shoots 7 arrows, what is the probability of each of the results described in parts a through f below? c) Her first miss comes on the second or third arrow The probability is 0.2239 (Round to four decimal places as needed.) d) She misses the bull's-eye exactly 3 times. The probability is 0.0525. (Round to four decimal places as...
Ch6 Q7 An Olympic archer misses the bull's-eye 11% of the time. Assume each shot is independent of the others. If she shoots 9 arrows, what is the probability of each of the results described in parts a through f below? a) Her first miss comes on the third arrow. The probability is __________________ (Round to four decimal places as needed.) b) She misses the bull's-eye at least once. The probability is __________________ (Round to four decimal places...

An archer shoots an arrow at a 73.0 m distant target, the bull's-eye of which is at same height as the release height of the arrow. (a) At what angle must the arrow be released to hit the bull's-eye if its initial speed is 33.0 m/s? (Although neglected here, the atmosphere provides significant lift to real arrows.) Incorrect: Your answer is incorrect. °
A) The distribution of exam scores for Statistics is normally distributed with a mean of 78 and a standard deviation of 5.2. What is the z-score for a raw score of 85? Round to the nearest hundredth. B) An Olympic archer is able to hit the bull’s eye 80% of the time. Assume each shot is independent of the others. She will shoot 6 arrows. Let X denote the number of bull’s eyes she makes. Find the standard deviation of...
An archer shoots an arrow at a 73.0 m distant target, the bull's-eye of which is at same height as the release height of the arrow. (a) At what angle must the arrow be released to hit the bull's-eye if its initial speed is 35.0 m/s? (Although neglected here, the atmosphere provides significant lift to real arrows.) ° (b) There is a large tree halfway between the archer and the target with an overhanging branch 3.50 m above the release...
