Product preference depends in part on the age, income, and gender of the consumer. A market researcher selects a large sample of
potential car buyers. For each consumer, she records gender, age, household income, and automobile preference. Which of these variables are categorical and which are quantitative? gender 1---Select---categorical quantitative
age 2---Select---quantitative categorical
household income 3---Select---quantitative categorical
automobile preference4 Select---quantitative categorical
Answer: Gender = categorical ; Age = quantitative ; Household income = quantitative ; Automobile preference = Categorical
Step-by-step explanation:
Distinction between quantitative and categorical variables are based made on whether the variables are represented with a numeric or non-numeric value. Categorical variables usually takes in strings such as in the scenario above, the appropriate input for gender will be either 'Male' or 'Female' and Automobile preference will be a string of the type of automobile which the user prefers. On the other hand, quantitative variables will accept numeric values such as age and household income.
Knowing the halfway point (which is 5) helps you so you know wither or not the hundred thousands place goes high or stays the same. So, for this problem 138,202 would round out to 100,000 because the 3 is below 5 so the hundred thousands place stays the same.
1600. This is a maximum limit of fish the pond can host.
Step-by-step explanation:
For , we must take the part of this function valid for high values, i.e., the second part, where .
Since we have two polynoms both in numerator and denominator, and both of them are of degree 1 (both linear), for high values of , the main part of each polynom shall be the linear part, neglecting lower degree parts (in this case, constant terms):
This means that the number of fish in a pond has an <em>horizontal asymthote</em>. In other words, there seems to be a natural limit for the number of fish that there will be in the pond as years pass. The maximum number of fish is actually 1600. With this function, no higher than this figure can be reached. This might imply <em>limits in productivity</em>.
