Determine whether you can use a normal distribution to approximate the binomial distribution.
if you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs.
if you cannot, explain why and use a binomial distribution to find the indicated probabilities. a survey of u. s. adults found that 64% watch nfl football. you randomly select 20 u. s. adults and ask them whether they watch nfl football.
find the probability that the number who watch nfl football is:

(a) exactly 10
(b) less than 7
(c) at least 15
(d) identify any unusual events.

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
