In new Zealand there is a river known as the kaituna. on it, there exists a 23- foot waterfall; some peoplelike to go over the waterfall on a raft. a group of 6 people decide to give it a try; they consist of four adults and two teenagers.
the raft must be travelling at least 30 miles per hour in order to successfully go over the falls; otherwise it will tip over. the river flows at one-sixth of the needed speed. an adult can paddle the same speed as two adults.
how fast is the raft travelling?
will the group be able to make it over the falls without tipping over?

i have no answer for this maybe o 7 units

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

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.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
