What is the solution to 3 + 4e^x+1 = 11?
Solution:
To solve for x, Let us subtract 3 from both sides
Let us divide by 4 on both sides
Let us take ln on both sides
So, x+1=ln(2)
To solve for x, Let us subtract 1 from both sides
x+1-1=ln(2) -1
x+0=ln(2)-1
x= ln(2) -1
Answer: Option (A)
x=ln(2)-1
Answer:
FALSE
Step-by-step explanation:
A binomial distribution is a data distribution where there are only 2 possible outcomes A or B.
If probability p is assigned to outcome A, and probability q is assigned to outcome B, then q = 1 - p.
In a binomial distribution, the mean is np, where n is the size of the sample, and the skewness is
As you can see, if p is different to 0.5 a binomial distribution is always skewed, and the skewness is independent of the sample size. Moreover, the sign of the skew only depends on the sign of 1 -2p
In this problem, we could have named:
<u>Event A</u> : The interviewed answered “YES” to the question “Do you start the day with a cereal breakfast?”
<u>Event B</u>: The interviewed answered “NO” to the question “Do you start the day with a cereal breakfast?”
In this case p = 0.8 and the skewness would be negative, so the distribution would be left skewed.
