Businesses often segment the market based on key demographics such as age, gender, income level or marital status, but they also use more precisely defined categories to target specific groups.
Answer: 0.48
Explanation:
P(A/B) = P(AnB)/P(B) where:
P(A/B) = The probability of event A occurring given that B has occurred.
P(AnB) = The probability of both events A and B occurring.
P(B) = the probability that event B occurs.
So let
P(A) = Probability that the residents of a household own 2 cars.
P(B) = Probability that the annual household income is greater than $25,000.
The question tells us that
P(A/B) = 0.8
Note that: P(A) = 0.7, P(B) = 0.6.
Since we want to work out P(AnB), because it gives the probability that residents have an annual household income over $25,000 and own 2 cars.
We would Rearrange our initial equation to make P(AnB) the subject formula becoming;
P(A/B) = P(AnB)/P(B)
P(B)*P(A/B) = P(AnB)
So, inserting our probabilities into this equation gives:
0.6*0.8 = 0.48
Note:
I wasn't able to access the Chester Income Statement but I successfully accessed a similar question Digby.
The Complete Question is as under:
Refer to the HR Reports in the Inquirer. Through past investments in recruiting and training Digby has obtained a productivity index of 109.6%. This means that Digby's labor costs would be increased by 9.6% if it did not have these productivity improvements. This is a competitive advantage that Digby can sustain or even widen further if its competitors have no HR initiatives. Now, refer to the Income Statement in Digby's Annual Report. How much did Digby's productivity improvements save it in direct labor costs (in thousands) last year?
A. $766
B. $29818
C. $3137
D. $3211
Answer:
Option D. $3,137
Explanation:
The Productivity Index of 9.6% shows that if the improvement plan is implemented then the efficiency gains would result in saving of 9.6% of total direct cost. So if we total the direct cost for the year for all of the four products then we have an amount of $32,680 which is given at the second last column.
The amount saved last year would be:
Savings = $32,680 * 9.6% = $3,137
Hence the option C is correct here.
Answer: According to Ian Redpath and Greg Urban, the threshold amount required for conclusively stating whether a substantial basis adjustment is mandatory is $250,000. The amount required is $250,000 in order for one to know whether they are in need for a substantial basis reduction or maybe not. It's required when the amount indeed exceeds $250,000.
