MOE = +\- 1.27
The 99% confidence interval ranges from 53.73 to 56.27 hours.
9(10+x)
To apply the distributive property, we need to multiply the number out of the parenthesis by each number inside.
9*10 = 90
9*x = 9x
9x + 90
Final answer: 9x + 90
Subtract 6 from both sides, you get 1/3x=-14
Now multiply both sides by there, hence x=-42
Answer:
14.7
Step-by-step explanation:
Perhaps your equation is ...
f(t) = N·e^(-0.2174t)
We want f(6) = 4, so ...
4 = N·e^(-0.2174·6) = N·e^-1.3044 ≈ 0.2713N
N = 4/0.2713 = 14.7 . . . . milligrams
The dose amount was about 14.7 mg.
