Niacin is particularly important for men over 50 since it helps them to maintain healthy blood cholesterol levels. A researcher randomly selects 10 men over 50 years old and ascertains whether or not each individual's level of niacin in his bloodstream is high, average, or low. Does this constitute a binomial experiment?

The experiment conducted by the researcher does not constitute a binomial experiment.

Step-by-step explanation:

A researcher wants to determine the level of Niacin in men over the age of 50 years.

In any particular man, the level of Niacin is either high, average or low.

This implies that for every sample there are three different outcomes.

The experiment performed by the researcher is not a Binomial experiment.

In a Binomial experiment, there are n independent and repeated trials.

Each trial has only two outcomes: Success (S) or failure (F).

And each outcome has the same probability of occurrence.

Thus, the experiment conducted by the researcher does not constitute a binomial experiment.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
