In binomial distribution, 
n=sample size =69
p=probability of success = 0.29
mean = np = 69*.29= 20.0100
variance = npq = np(1-p) =20.01(1-0.29)=14.20710
standard deviation=sqrt(variance)=3.76923
(round to appropriate number of decimal places)

Solve for x. PLEASE HELP ASAP WILL GIVE BRAINLIEST ANSWER

Answer:

x = 2.6  

Step-by-step explanation:

To find x, you need to find how many times you need to multiply 25 to get 65. Using reverse operations will make this easier. 65 / 25 = 2.6. We can check this by multiplying 25 by 2.6, and we get 65.
