Answer
b. No
Step-by-step explanation:
We can easily solve this question by using a graphing calculator or any plotting tool, to check if it is a sinusoid.
The function is
f(x) = sin(20*x) + cos(8*x)
Which can be seen in the picture below
We can notice that f(x) is a not sinusoid. It has periodic amplitudes, and the function has a period T = π/2
The maximum and minimum values are
Max = 1.834
Min = -2
Start by changing the -8y to plus a negative 8y.
Now combine your "x" terms and your "y" terms.
So -5x + 5x is 0x and 2y + -8y is -6y.
So the answer is 0x - 6y or just -6y.
Answer:
4x+2y-1/4y+3

Answer:
a. The sampling distribution of the sample mean will have a smaller standard deviation than the population.
b. The sampling distribution of the sample mean will have a different standard deviation than the population.
c. The shape of the sampling distribution of the sample mean will be skewed right.
Step-by-step explanation:
We are asked to evaluate <span>(sqrt(t)+t^2)/(2t-t^2) as t approches infinity. In this case, when infinity is substituted, the answer is infinity/infinity which is an indeterminate number. Using L'hopital's rule, we differentiate separately the tems in the numerator and denominator. This is equal to [0.5t^-0.5 + 2t] / [2 - 2t]. In this case, 1/infinity is equal to zero but still the quotient is equal to infinity over infinity. We derive again. [0.25t^-1.5 + 2] / [-2]. Substituting, the final answer is -1.</span>
