1) A modification problem takes places when creating a database two different type of information is entered in the same chart row generating inaccuracy. The only form to solve this issue is creating a new row so each piece of information will be stored in one row particularly.
2) There are three (3) types of modification problems: the deletion problem (<em>the single row containing information from different themes can be deleted losing data</em>), the update problem (<em>new information entered could lead to more inconsistency</em>), and the insertion problem (<em>similar to deletion, a new row can be inserted instead of the row causing problem but information will be missing</em>).
Answer:
a) 0.0358
b) 0.0395
c) 0.1506
Explanation:
Number of clues "daily doubles" = 3
Determine the probabilities
<u>a) P(single contestant finds all three ) </u>
assuming event A= a returning champion gets the "daily double" in first trial
P(A) = 1/30 , P(~A) = 29/30
assuming event B = any player picks up "daily double" after the first move
P(B |~A ) = 1/3
hence : P ( B and ~A ) = 29/30 * 1/3 = 29/90
<em>considering second round </em>
P(player chooses both daily doubles ) = 1/3 * 1/3 = 1/9
∴ P(single contestant finds all three ) = 29/90 * 1/9 = 0.0358
<u>B) P ( returning champion gets all three ) </u>
= (1/30 + 29/90 )* 1/9
= 32 / 810 = 0.0395
<u>c) P ( each player selects only one )</u>
P = 32/405 + 29/405
= 61 / 405 = 0.1506
Answer:
Effect on income= $68,580 increase
Explanation:
<u>Because it is a special order, and there is unused capacity, we will not take into account the fixed costs. Only the variable ones.</u>
<u>First, we need to calculate the unitary cost:</u>
Unitary cost= 46.1 + 8.8 + 1.8 + 1.3
Unitary cost= $58
<u>Now, the effect on the income of accepting the offer:</u>
Effect on income= 2,700*(83.4 - 58)
Effect on income= $68,580 increase
The area that consumes the majority of a family’s income is Housing.
This is according to the Bureau of Labor Statistics' info for 2017.
