Answer:
B
Step-by-step explanation:
2x+y=-6 the equation has to be in slope form (y=mx+b) the first thing that you have to do is find the slope which you can do fairly easy by moving the 2x to the other side of the equation. Y=-2x-1 then you use that slope and use a different y intercept for the two lines to be parallel
Answer: Option 'D' is correct.
Step-by-step explanation:
If there is difference between the sample mean and the population mean, then it is known as "Sampling error".
As we know that standard error of the mean is given by
![\dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
and the sampling error refers to the difference in the value of sample mean and the value of population mean.
Hence, Option 'D' is correct.
Answer:
![\boxed{\boxed{C.\ \text{f(x)} = 120000(1.055)^x}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7BC.%5C%20%5Ctext%7Bf%28x%29%7D%20%3D%20120000%281.055%29%5Ex%7D%7D)
Step-by-step explanation:
This is the case of an exponential growth. The function for exponential growth is,
![y(t)=y_0(1+r)^t](https://tex.z-dn.net/?f=y%28t%29%3Dy_0%281%2Br%29%5Et)
where,
- y(t) = value after time t = f(x)
- y₀ = initial value = $120,000
- r = rate of growth = 5.5% = 0.055
- t = number of periods = x years
Putting the values,
![\text{f(x)} = 120000(1+0.055)^x\\\\\text{f(x)} = 120000(1.055)^x](https://tex.z-dn.net/?f=%5Ctext%7Bf%28x%29%7D%20%3D%20120000%281%2B0.055%29%5Ex%5C%5C%5C%5C%5Ctext%7Bf%28x%29%7D%20%3D%20120000%281.055%29%5Ex)
