Answer: ![f(x)=15500(1.0375)^x](https://tex.z-dn.net/?f=f%28x%29%3D15500%281.0375%29%5Ex)
Step-by-step explanation:
The exponential model for growth is given by :-
, where A = initial value , r = growth rate (in decimal), x = time (in years).
Given: A= 15,500 r= 3.75% = 0.0375
The exponential model for the growth of this population will be :
![f(x)=15500(1+0.0375)^x\\\\\Rightarrow\ f(x)=15500(1.0375)^x](https://tex.z-dn.net/?f=f%28x%29%3D15500%281%2B0.0375%29%5Ex%5C%5C%5C%5C%5CRightarrow%5C%20f%28x%29%3D15500%281.0375%29%5Ex)
hence, the required model: ![f(x)=15500(1.0375)^x](https://tex.z-dn.net/?f=f%28x%29%3D15500%281.0375%29%5Ex)
10, ten is the gcf that’s your answer.
Answer:
0.01 is the difference between the 2006 study and the sampe which is negligible hence why we can't say the proportion of Americans who are afraid to fly has increased.
Step-by-step explanation:
In 2006, the proportion of Americans afraid to fly is 0.10.
Then a random sample of 1300 Americans results in 143 indication that they are afraid to fly.
The proportion for this random sample is:
![\frac{143}{1300} = 0.11](https://tex.z-dn.net/?f=%5Cfrac%7B143%7D%7B1300%7D%20%20%3D%200.11)
0.11 is the proportion of Americans afraid to fly based on the random sample.
This proportion is not necessarily evidence that the proportion of Americans who are afraid to fly has increased because the difference between the proportion of the sample and the 2006 study is negligible.
The difference is:
![0.11 - 0.10 = 0.01](https://tex.z-dn.net/?f=0.11%20-%200.10%20%3D%200.01)
and 0.01 is negligible.
Answer:
114.89 V
Step-by-step explanation:
Watts are a measure of power, and there is an equation that relates power, voltage, and resistance. It goes like this:
P=(V^2)/R
Now to find the voltage you want to solve for V
PR = V^2
V = ![\sqrt{PR}](https://tex.z-dn.net/?f=%5Csqrt%7BPR%7D)
Now substitute your numbers into the equation and you get your answer
V = ![\sqrt{(60)(220)}](https://tex.z-dn.net/?f=%5Csqrt%7B%2860%29%28220%29%7D)
V = ![\sqrt{13200}](https://tex.z-dn.net/?f=%5Csqrt%7B13200%7D)
V = 114.89 V
