Answer:

The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919. In the United States, it was first identified in military personnel in spring 1918. It is estimated that about 500 million people or one-third of the world’s population became infected with this virus. The number of deaths was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States.

2.. Kerri took 2 and 1/2 hours to read a 460 page book. At this rate, how long will it take her to read a 1250 page book?

kirill115 [55]

Answer:

Step-by-step explanation:

reading_rate: 2.5R = 1250

R = 1250/2.5 = 500 pages/hr or ( 1 hr)/(500 pages)

Solve for hr?

=( 1 hr)/(500 pages) * 1250 pages

now, cancel out pages and we are left with hours

= 1250/500 hours

= 2.5 hours

Five percent of all blue ray players manufactured by a large electronics company are defective. A quality control inspector rand

iVinArrow [24]

Answer:

0.1354 = 13.54% probability that exactly one of these three blue ray players is defective.

Step-by-step explanation:

For each player, there are only two possible outcomes. Either it is defective, or it is not. The probability of a player being defective is independent of any other ray. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Five percent of all blue ray players manufactured by a large electronics company are defective.

This means that $p = 0.05$

A quality control inspector randomly selects three players from the production line.

This means that $n = 3$

What is the probability that exactly one of these three blue ray players is defective?

This is P(X = 1). So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 1) = C_{3,1}.(0.05)^{1}.(0.95)^{2} = 0.1354$

0.1354 = 13.54% probability that exactly one of these three blue ray players is defective.
