Amarketing firm is studying consumer preferences for winter fashions in four different months. from a population of women 18-21 years of age, a random sample of 100 women was selected in january. another random sample of 100 women was selected in march. another random sample of 100 women was selected in june. another random sample of 100 women was selected in september. what is the number of samples?

There were total 4 samples collected and each sample had a sample size of n = 100.

Step-by-step explanation:

We are given the following information in the question:

Collection of samples:

Hence, there were total 4 samples collected and each sample had a sample size of n = 100.

4x and 6y

im not sure though

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
