Answer:
x = 3, y = -3
Step-by-step explanation:
3x - 2y = 15 (eq 1)
x + y = 0 (eq 2)
(eq 2) x 2
2x + 2y = 0 (eq 3)
(eq 1) + (eq 3)
5x = 15
x = 3
SUB x=3 into (eq 2)
3 + y = 0
y = -3
In the question "Total output is a synonym for". The correct answer is production.
Output in economics is the "quantity of goods or services produced<span> in a given time period, by a firm, industry, or country", whether consumed or used for further production.</span>
Answer:
The degrees of freedom is 11.
The proportion in a t-distribution less than -1.4 is 0.095.
Step-by-step explanation:
The complete question is:
Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom used. Find the proportion in a t-distribution less than -1.4 if the samples have sizes 1 = 12 and n 2 = 12 . Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places. degrees of freedom = Enter your answer; degrees of freedom proportion = Enter your answer; proportion
Solution:
The information provided is:

Compute the degrees of freedom as follows:


Thus, the degrees of freedom is 11.
Compute the proportion in a t-distribution less than -1.4 as follows:


*Use a <em>t</em>-table.
Thus, the proportion in a t-distribution less than -1.4 is 0.095.
.55 is the answer. I hope this helped a great deal!
