Answer: B. 12.55
Step-by-step explanation:
Given: In a binomial event , the probability of success = 0.3
i.e. p =0.3
Then, q=1-P=1-03=0.7
The total number of trial performed n= 750
Now, the standard deviation of the proportion is given by :-

Hence, the standard deviation of the possible outcomes = 12.55

Answer:
Step-by-step explanation:
All equations where x=2 is a solution : a(x-2) = 0......a ≠ 0
In similar triangles, the ratios of corresponding sides are equal.
This means
y/6=5/(4+5)
Cross multiply
y=5*6/(4+5)=30/9=10/3 (or 3 1/3)
