The expression 3h? + 4 represents the total amount of grain, in pounds, that is harvested on a farm h hours into each workday. If the harvesting rate continues to follow this
model, which inequality represents the time, in hours, when the total amount of grain
harvested will be at most 100 pounds?

B.

Step-by-step explanation:

total amount of grain, in pounds, harvested = , where, h = hours.

If at most 100 pounds will be harvested, it means the what will be harvested in pounds after working for some h hours, would be 100 pounds or less than 100 pounds. The highest is 100 pounds. "At most 100 pounds" means "less than or equal to 100 pounds".

The inequality that represents the time in hours would be:

✅

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.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
