Suppose a binomial event has a probability of success of 0.3, and 750 trials are performed. what is the standard deviation of the possible outcomes? round your answer to two decimal places.
a. 16.20
b. 12.55
c. 8.22
d. 10.61

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

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
