Step-by-step explanation:
Answer:
12 is 25 percent of 48.
Step-by-step explanation:
To find the solution to this problem, you'll first want to convert the word problem to an equation. We can find key words in the word problem that will give us information about what we're doing and change the percentage into a decimal since both are ways to write numbers less than 1.
If we know that the word 'of' means we should multiply, we can write the equation like this:
12 = .25 * x
where x is the mystery number we are trying to find. Divide both sides by .25 to get x by itself (since any number divided by itself equals 1).
12 / .25 = .25 / .25 * x
12 / .25 = x
48 = x
To check our work, if you know that 25% is one quarter (1/4) of a whole, we can multiply 12 by 4 to find our whole.
12 * 4 = 48
Answer:
The distribution is
b) skewed.
The sum of the probabilities is:
1
Step-by-step explanation:
In a binomial distribution, p represents the probability of success. Success in the sense that the event of interest happens. In the model presented, the probability of success p is 0.4 since we are informed that 40% of adults watch a particular television show.
The next quantity of significance in a binomial model is the number of independent trials, n. In our case there are 6 independent trials since we are told that 6 adults were selected at random. If we let the random variable K denote the number of adults out of the 6 who watch the television show, then K is a binomial random variable with parameters;
n = 6 and p = 0.4
A binomial distribution is only symmetric when either p is 0.5 or n is large. In the presented scenario none of this conditions is met since p is 0.4 while n is just 6 which is relatively small. Thus we conclude that the distribution is not symmetric but rather skewed.
The sum of the probabilities is any discrete probability distribution such as the bernoulli, binomial, negative binomial, poisson, or the geometric distribution is always equal to 1. That's a rule of thumb.
