Answer:
D. Using customer's past purchase history to send information about related products and services the customer may be interested in
Explanation:
Data mining is the process whereby large pre existing databases are examined with the aim of generating new information. It is the extraction of usable data from a larger set of data. Company usually use this process to turn raw data into useful information that can be applied to their daily activities.
In the case of marketing, data mining helps in extracting useful information from a customer's purchase history in order to identify useful information on goods or services the customer may be interested in or attracted to.
Answer:
The second gamble has the higher expected value. EV = 4
Explanation:
In betting, expected value can be defined as (Amount won per bet * probability of winning) – (Amount lost per bet * probability of losing)
For the first gamble:
For the second gamble:
This means that Cal is expected to earn $4 for each $20 waged on the second gamble while he is expected to break even in the first gamble.
Therefore, the second gamble has the higher expected value.
If the average cost of producing 9 sweaters is $6. 50 and the marginal cost of producing the tenth sweater is $6. 25, the average cost of producing 10 sweaters will be less than $6.50
If marginal cost is less than average cost, average cost will decrease and therefore be less than $6.50. In this case, average cost of producing 10 sweaters is ($6.50 x 9 + $6.25)/10 = $6.48.
The marginal cost is the variation in total cost brought on by an increase in output, or the cost of producing more. In certain contexts, it might refer to an increase in output of one unit, while in others, it can relate to the rate of change of total cost as output grows by a modest amount.
The total cost is expressed in dollars, whereas the marginal cost is expressed in dollars per unit. The marginal cost is the slope of the total cost, or the rate at which it increases with production.
Marginal cost is the distinction between average cost, which is the total cost divided by the number of units produced.
