Answer:
A - one
Step-by-step explanation:
A typical demand curve, in economics, depicts the relationship between price of a commodity on the y-axis, and quantity demanded on the x-axis.
The demand curve obeys the Law of Demand, which states that the higher the price, the lower the quantity demanded of that commodity, and vice versa, all things being equal. Thus, a typical demand curve will slope downwards, from left to the right.
Therefore, line 1 indicates the demand curve.
Answer:
x = 20 * s / 300
Step-by-step explanation:
In this case, it is solved by means of a rule of three, that is, we know that 20 of 300 answered yes, but in the case of the strata sample, since it is a value that is not mentioned in the problem, we will assume it as " s "and the people who were selected as" x ". would:
20 x
300 s
Therefore, x:
x = 20 * s / 300
and thus they would give us the number of people that would be selected.
For example, if "s" were 240, it would be:
x = 20 * 240/300
x = 16
that is, 16 people would be selected
(3)(17.25) = 51.75; he spent $51.75
Because everything in the problem is positive, no negative numbers are needed.
