Explanation
Sentence B is correct because it employs the use of a semicolon to separate two independent clauses. The use of the conjunction, <em>however</em>, helps to separate two sentences that have opposite connotations.
Sentence D is correct because the conjunction, and, was used appropriately to add a second thought to the sentence. The comma was also used correctly as it spliced the sentence and was immediately followed by the conjunction, <em>and</em>.
Answer:
a. 2.13. b. (30.53, 34.79). c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.
Explanation:
The size of the sample is 42 and the mean of the sample is ∑
= 32.66 and the standard deviation of the sample (σ) is √[∑(
-μ)^2 - 1] = √46.6092 = 6.8271
a. α = 1 - (95/100) = 0.05; α/2 = 0.025; the degree of freedom = n-1 = 42-1 = 41; tα/2 = t0.025 = 2.02. Thus, the error margin = (tα/2)*(σ/√n) = 2.02*(6.83/√42) = 2.1279
b. Lower level limit = 32.66 - 2.1279 = 30.5321; Upper level limit = 32.66+2.1279 = 34.7879. The interval estimate = (mean± margin of error) = (30.53, 34.79).
c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.
Answer: Law of diminishing marginal utility
Explanation: In simple words, law of diminishing marginal utility states that as a consumer consume more of a good or service then the marginal benefit he or she receives from the additional consumption keeps on decreasing.
In the given case, Jenny's excitement keeps on decreasing with every chocolate she receives after a certain point of time.
Hence we can conclude that the given case illustrates law of diminishing marginal utility.
<u>Answer: </u>True
<u>Explanation:</u>
Here for calculation of the profit or loss the cost of production cannot be used for comparison as they are the sunk cost it cannot be used for taking sale or rework decision. It is given the proceeds from the sale of inventory would be $425,000 and the cost of rework will be $150,000.
Net proceeds from sale of units = 425000 - 150000
=$275,000
It is clear that these profits are lower than the sale of these units without repair. Sale proceeds without repair is $325,000. So MR corporation can make decision to sell the units without repair for better benefits.
