Answer:
4.75%
Step-by-step explanation:
When simple interest is charged, the payback amount is ...
A = P(1 +rt) . . . . for annual rate r and a term of t years
Using the given values, we can solve for r.
10280 = 8000(1 +6r)
1.285 = 1 +6r . . . . . . . . divide by 8000
0.285 = 6r . . . . . . . . . . subtract 1
0.285/6 = r = 0.0475 = 4.75% . . . . . . divide by 6; express as %
Theo paid interest at the rate of 4.75%.
The answer is 0.88889, because:
Order of Operations-
1) Add 30 plus 6 to get 36
2) Subtract 32 from 36 to get 4
3) Divide 4 by 9 to get 0.4444444
4) Multiply 0.4444444 by 2 to get 0.888889
Good luck! <3
It is 9- is tha answer need the formula
Answer:
The result is significant.
Step-by-step explanation:
Here,
p = 30 ÷ 330 = 0.091
thus, q = 1 - p = 0.909
Also, 
⇒ 
The z-score is:


Thus, at 95% confidence interval, p-value = 0.005
The result is significant at p < .05.
