Answer:
3 2/3
Step-by-step explanation:
If the mean is 11 and there are 5 numbers then their sum is 5 × 11 = 55 We have the ratio of parts being a : b : c : d : e → 1 : 2 : 3 : 4 : 5 so the total count of parts is 1 + 2 + 3 + 4 + 5 = 15. a-1/15x55=55 divided by 5/ 15 divided by 5=11/3=3 2/3
Answer: Both 4 barrels and 7 barrels of beer per crates of olives will allow both Germany and Portugal to gain from trade.
Step-by-step explanation: For every 1 crate of olives produced by Portugal, they will not be able to produce 3 barrels of beer in return. Therefore, for portugal to trade a crate of olives for barrels of beer more than 3 means they are gaining on the trade, in this case, they gain 1 (option A) and 4(option B) extra barrels of beer for every crate of olive traded with Germany. Likewise Germany gains in both cases because any exchange of barrels of beer that is less than 11 barrels of beer to a crate of olives is a gain for Germany. Therefore both 4 barrels and 7 barrels for a crate of olives will lead to both countries gaining.

Step-by-step explanation:
7321=9
After x years the value (V) is:
<span>Original - 4000x </span>
<span>so, after 3 years we have: </span>
<span>Original - 12000 = 18000 </span>
<span>b: Original = $30,000 </span>
Answer: The null and the alternative hypotheses are given below:
Under null hypothesis, the test statistic is:
Now we have to find the left tailed critical value at 0.01 significance level using the standard normal table.
The critical value is:
Since the test statistic is -0.26 lies in acceptance region because the critical region is beyond -2.33, therefore, we fail to reject the null hypothesis.
