Answer:

t = 3.156

Step-by-step explanation:

N = 9

Please check attachment for the table

ED = 89

ED² = 1587

Bar D = 89/9

= 9.8889

The standard deviation s

= √14283-7921/81

= √78.5432

S = 8.8625

The test statistic

= 9.8889/8.8625/√9-1

= 9.8889/3.1334

= 3.156

From the calculations above, the calculated test statistic t is = 3.156.

Please check the attachment for a more detailed solution to this problem.

Thank you!

Jake is buying a piece of recycled art from Luna. He started by giving her $50 and promised to pay her $5 a week until he pays t
garri49 [273]

Answer: t = 50 + 5 w

Step-by-step explanation:

Here w shows the number of weeks and t shows the total amount in w weeks.

Since, the initial amount he paid to her = $ 50

After that he paid $ 5 per week.

Thus, the total extra amount he paid = 5 w

⇒ The total amount he paid to her = 50 + 5 w

⇒ t = 50 + 5 w

Which is the required relation between the total amount paid(t) and  the number of weeks (w) Jake will take to pay Luna.
