A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria, the person will fall sick. Let’s suppose 100 such bacteria entered a person’s blood. How many hours will it take for the person to become sick? Arrange the steps in the right order to show how to find the number of hours it will take for the person to fall sick.
45,000,000 = 100(1 + 1.5)t
450,000 = (2.5)t
log 450,000 = t log(2.5)
45,000,000 = 100(2.5)t

log 450,000 = log(2.50)t

14.21 hours = t

Step-by-step explanation:14 hrs 12 minutes

Given that a certain kind of bacteria multiplies at a rate of 150 percent per hour.

Initial bacteria = 100

Growth is 150% hence P(t) = no of bacteria present at time t is exponential as

A person will fall sick if the number of bacteria is 45,000,000

i.e.

Take log on both sides

i.e. in 14 hours and 12 minutes a person will fall sick

step-by-step explanation:

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
