Answer:
A) 12.48 million
Step-by-step explanation:
To solve this problem, we need to figure out what 26% of 48 million is. We will need to multiply 48,000,000 by 26% to get our answer. Don't forget that we will also need to switch 26% to its decimal form (26% - > 0.26).
48,000,000 x 0.26 = 12,480,000
Our answer is 12,480,000 or in other terms $12.48 million. This means that A is the best answer.
A statistical question will have more than one answer. Questions like, “How old are the students in my school?”or “What time did the students in this class get up this morning?” are examples of a statistical question. Pretty much if it involves asking more the one people it’s a statistical question because it will lead to more than one answer.
Suppose the student guesses the answers, we shall consider this a binomial probability problem of success. This implies that getting a question right is p=1/5.
The number of questions is n=20 questions.
The mean of binomial distribution is
mean=n*p= 20*1/5=4
b] The standard deviation of a binomial distribution is given by:
σ=√(n*p*(1-p))
=√(20*0.2*0.8)
=1.79~1.8
Answer:
μ=4 ; σ=1.8
The answer would be 3 to 1 as there are 3 dogs and 1 cat and the question asks for the ratio of dogs to cats.
