Answer:
The domain of f(x) indicates x > -2, meaning the range of f-1(x) will be y > -2
The range of f(x) identifies y > -1, thus the domain of f-1(x) is x > -1
Step-by-step explanation:
Step-by-step explanation of the answer:
Sam allocated $48,000 with 6% interest and the remainder at 10%. He earned a total of $4,000 in interest over the course of one year, and now we need to determine the amount invested at each rate.
Let us denote the amount invested at 6% as
.
![(\frac{6}{100} \times x)+(\frac{10}{100} \times [48000-x])=4000](https://tex.z-dn.net/?f=%28%5Cfrac%7B6%7D%7B100%7D%20%5Ctimes%20x%29%2B%28%5Cfrac%7B10%7D%7B100%7D%20%5Ctimes%20%5B48000-x%5D%29%3D4000)





This results in the 6% investment being $20,000 and the 10% investment totaling = (48000 - 20000) = $28,000
It should be option B, since you'd need two angles to make a definitive conclusion.
P = Number of successful outcomes resulting in 4 on the final roll / Total outcomes.
Ways to get 4 only on the last attempt = 5 * 5 * 5 * 1 = 125 (the first three rolls have 5 options that are not 4, and for the last roll, only 4 is available (1 way)). The overall total number of outcomes = 6 * 6 * 6 * 6 = 1296. Thus, P = 125/1296.
