Answer:
Step-by-step explanation:
![y=a(1+r/c)^{ct}\\ \\ y=9000(1+.042/12)^{12t}\\ \\ y=9000(1.0035)^{12t}\\ \\ a)\ y=9000(1.0035)^{12(10)}=\$ 13687.61\\ \\ b)\ 15400=9000(1.0035)^{12t}\\ \\ 1.0035^{12t}=77/45\\ \\ 12t ln(1.0035)=ln(77/45)\\ \\ t=(ln(77/45))/(12ln(1.0035))\\ \\ t\approx 12.8\ years](https://tex.z-dn.net/?f=y%3Da%281%2Br%2Fc%29%5E%7Bct%7D%5C%5C%20%5C%5C%20y%3D9000%281%2B.042%2F12%29%5E%7B12t%7D%5C%5C%20%5C%5C%20y%3D9000%281.0035%29%5E%7B12t%7D%5C%5C%20%5C%5C%20a%29%5C%20y%3D9000%281.0035%29%5E%7B12%2810%29%7D%3D%5C%24%2013687.61%5C%5C%20%5C%5C%20b%29%5C%2015400%3D9000%281.0035%29%5E%7B12t%7D%5C%5C%20%5C%5C%201.0035%5E%7B12t%7D%3D77%2F45%5C%5C%20%5C%5C%2012t%20ln%281.0035%29%3Dln%2877%2F45%29%5C%5C%20%5C%5C%20t%3D%28ln%2877%2F45%29%29%2F%2812ln%281.0035%29%29%5C%5C%20%5C%5C%20t%5Capprox%2012.8%5C%20years)
There are 6 different sides you can land on with a dice. So the probability of rolling any one side is 1/6. The probability of NOT rolling a 5 is the same thing as rolling anything except a 5. So that probability will be 5/6.
Answer:
ab = 280
or
a = 280/b
Step-by-step explanation:
Inverse variation is of the form
xy = k
Since we have a and b as our variables
ab = k
20 *14 = k
280 = k
ab = 280
Sometimes they write it as
a = 280/b
The answer would be around 1:3
