Answer:
13.5 hours
Step-by-step explanation:
If it takes Amy 12 hours to complete the job alone
And it takes Tom 15 hours to complete the same job alone,
How long will it take for both of them to get the job done together?
Amy= 12 hours
Tom= 15 hours
Amy + John =?
(12 + 15)/ 2
27/2= 13.5 hours.
So it would take Amy and Tom 13.5 hours to complete the job together.
Answer: 34 degrees of freedom should be used to find the p-value of the test .
Step-by-step explanation:
Degrees of Freedom relates to the maximum number of independent values, that have independence to vary in the sample.
Given : When testing the difference between two population means and the population variances are unknown and unequal, the degrees of freedom are calculated as 34.7.
But degree of freedom must be an integer , so we find the greatest integer less than equal to the calculated degree of freedom.
i.e. [df]=[34.7]= 34
Thus , 34 degrees of freedom should be used to find the p-value of the test .
Answer:
- 1.15585%
Step-by-step explanation:
Given that:
Sum of stock at beginning = $10,335.24
Sum of stock at the end of the day = $10,215.78
Rate of change of the Down Jones on that day :
The change in price on the day:
Ending - Beginning
10,215.78 - 10,335.24 = −119.46
The rate if change is thus ;
(Change in price / beginning stock price) * 100%
(-119.46 / 10,335.24) * 100%
-0.0115585 * 100%
- 1.15585%
